Detailed Description

Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While certain embodiments of the present disclosure have been illustrated in the accompanying drawings, it is to be understood that the present disclosure may be embodied in various forms and should not be construed as limited to the embodiments set forth herein, but rather, these embodiments are provided so that this disclosure will be more thorough and complete. It should be understood that the drawings and embodiments of the present disclosure are for illustration purposes only and are not intended to limit the scope of the present disclosure.

In describing embodiments of the present disclosure, the term "comprising" and its like should be taken to be open-ended, i.e., including, but not limited to. The term "based on" should be understood as "based at least in part on". The term "one embodiment" or "the embodiment" should be understood as "at least one embodiment". The term "some embodiments" should be understood as "at least some embodiments". Other explicit and implicit definitions are also possible below. The terms "first," "second," and the like, may refer to different or the same object. Other explicit and implicit definitions are also possible below.

Embodiments of the present disclosure may relate to user data, the acquisition and/or use of data, and the like. These aspects all follow corresponding legal and related regulations. In embodiments of the present disclosure, all data collection, acquisition, processing, forwarding, use, etc. is performed with knowledge and confirmation by the user. Accordingly, in implementing the embodiments of the present disclosure, the user should be informed of the type of data or information, the range of use, the use scenario, etc. that may be involved and obtain the authorization of the user in an appropriate manner according to the relevant laws and regulations. The particular manner of notification and/or authorization may vary depending on the actual situation and application scenario, and the scope of the present disclosure is not limited in this respect.

As mentioned briefly above, vehicles are now becoming more and more widely used with the increasing standard of living, and driving and traveling have been the most common means of transportation in life for people. To better assist the user decision, enhance the user experience, the navigation information is no longer limited to only providing direction information for guiding the direction of the user, but may also include other information for assisting the user in driving, such as signal light information. Such traffic light information is, for example, a current indication state of the traffic light (e.g., whether traffic is possible), a remaining time of the current indicated state, and the like. Accordingly, the vehicle driving user can determine the driving strategy, for example, whether to perform acceleration, deceleration driving, waiting time, etc., according to the signal lamp information. In this context, in order to further improve the use value of the alert information associated with the signal lamps, in some embodiments, a group of signal lamps capable of forming a green wave passing state is estimated based on the indication state of each signal lamp (in general, each signal lamp in a group of signal lamps having a green wave passing state may be referred to as a green wave signal lamp, a green wave band signal lamp, or the like). A green wave traffic state (or green wave band), meaning that there is a travel speed (which may also be referred to as a range of green wave speeds, typically a range of travel speeds) associated with a set of green wave signal lamps that can be continuously passed through when the vehicle is traveling at a travel speed that falls within the range of green wave speeds.

For example, one possible way is to determine green-wave traffic state information based on pre-planning information (such planning information may, for example, define a vehicle speed of a road section on a specified traffic route, and then require signal lights to make corresponding adjustments to the start time of the allowed traffic state of each intersection through which the traffic flow passes according to the road section distance, to form a set of green-wave signal lights), and bind such speed information with each signal light (i.e., green-wave signal lights), and subsequently, based on the binding information, the service provider may provide the user with corresponding green-wave traffic state information (e.g., the number of green-wave signal lights present in the current road section, and the corresponding vehicle speed interval).

However, in such a manner, not only is the green wave traffic relationship between the signal lights preconfigured, but because the green wave speed is actually directed to (or associated with) all of the signal lights, such a manner may result in a lower value of the green wave speed provided in situations where, for example, a user may only need to pass through a portion of the signal lights, may not need to travel at the green wave speed through all of the signal lights. In addition, in such a manner, since there is also explicit guidance (for example, informing the user that the user needs to accelerate to a certain speed to continuously and sequentially pass through the signal lights, otherwise, waiting) on the driving behavior of the user, the user may generate speed anxiety, which not only affects the user experience, but also may negatively affect the driving safety.

The embodiment of the disclosure provides a scheme for driving prompt. According to various embodiments of the present disclosure, a green wave speed range for traveling through a group of lights including a first light is determined based on a distance of a vehicle to the first light. In response to determining that the current speed of the vehicle falls within the green wave speed range, generating green wave alert information indicating at least one of: a green wave speed range and the number of signal lights in a group.

In the embodiment of the disclosure, after the green wave speed range can be determined, the green wave reminding is performed after the vehicle speed falls into the green wave speed range, so that the speed guiding of the user can be avoided, and the user is prevented from adapting to the green wave speed in a frequent acceleration and deceleration mode. Therefore, the green wave information can be provided to improve the passing efficiency, and the driving comfort and safety can be ensured.

Referring initially to fig. 1, fig. 1 illustrates a schematic diagram of an example environment 100 in which embodiments of the present disclosure may be implemented. In environment 100, terminal device 110, server device 120, and user 130 may be included. In some embodiments, terminal device 110 may also be associated with a display interface 111 such that it utilizes display interface 111 for interaction with user 130. The user 130 may communicate with the server device 120 using the terminal device 110 (e.g., the user 130 utilizes the display interface 111) to obtain driving assistance information (e.g., route information, signal light information). For example, the user 130 communicates with the server device 120 using the terminal device 110, and sends out a departure point (e.g., a location where the user 130 is currently located) and a destination to the server device 120 to obtain route information (e.g., route information planned by the server device 120) from the departure point to the destination. Accordingly, the server device 120 may determine auxiliary information (e.g., route information planned based on map information maintained in advance, traffic light information of a route determined based on the route information, etc.) based on the current location and destination of the user 130, and send the auxiliary information to the terminal device 110 for presentation to assist the user 130 in driving. Alternatively or additionally, the terminal device 110 may also extract status information based on the current driving status of the user 130 and present the status information to the user 130 for assistance, e.g. it may collect the current speed, position, etc. of the vehicle driven by the user 130. Accordingly, the terminal device 110 may send the collected status information (separately and/or simultaneously) such as speed, location, etc., to the outside of the server device 120, and present the status information to the user 130, e.g., using an interface of a display device associated with the terminal device 110 (e.g., the display interface 111 of the terminal device 110).

In environment 100, terminal device 110 may be any type of mobile terminal, fixed terminal, or portable terminal, including a mobile handset, desktop computer, laptop computer, notebook computer, netbook computer, tablet computer, media computer, multimedia tablet, personal Communication System (PCS) device, personal navigation device, personal Digital Assistant (PDA), audio/video player, digital camera/camcorder, positioning device, television receiver, radio broadcast receiver, electronic book device, game device, or any combination of the preceding, including the accessories and peripherals of these devices, or any combination thereof. Alternatively, the terminal device 110 may also be an appropriate electronic device mounted in the vehicle, for example, a center control device of the vehicle, a vehicle recorder mounted in the vehicle, an electronic rearview mirror, or the like. The server device 120 may be, for example, a computing system/server, such as a mainframe, edge computing node, computing device in a cloud environment, and so forth.

It should be understood that the structure and function of environment 100 are described for illustrative purposes only and are not meant to suggest any limitation as to the scope of the disclosure.

In this regard, some embodiments of the present disclosure provide a process for driving hints. Referring specifically to fig. 2, fig. 2 illustrates a flow chart of a process 200 for driving hints according to some embodiments of the present disclosure. Process 200 may be implemented at an appropriate electronic device or combination of electronic devices (e.g., terminal device 110 or a combination of terminal device 110 and server device 120 as shown in fig. 1). For ease of discussion, process 200 is described below with the combination of terminal device 110 and server device 120 as an example.

It should be appreciated that the type of signal light may be complex and varied during life, e.g., in some scenarios, the signal light may merely indicate whether traffic is possible in blue, white, or the status may be indicated by the presentation of a single indicator signal (e.g., the illumination, extinction of a single indicator light), or the signal light may also include intermediate states that indicate that traffic and non-traffic states are switched, e.g., a yellow light state. For convenience of understanding, in the following description, a signal indicating a "no-traffic state" is indicated by a "red light" and a "green light" is indicated by a "traffic light" for example.

In addition, to more clearly describe the process for driving cues, and the presentation examples associated therewith, process 200 will be described in connection with fig. 3 and 4. An example 300 of the server device 120 determining a green wave speed range in some embodiments is shown in fig. 3. An example 400 of green wave alert information displayed in terminal device 110 in some embodiments is shown in fig. 4.

At block 210, the server-side device 120 determines a green wave speed range for traveling through a group of lights including the first light based on the distance of the vehicle to the first light. In an embodiment of the present disclosure, the server device 120 obtains a distance of a vehicle (e.g., a vehicle driven by the user 130) to a first signal, which is typically a signal in front of the vehicle traveling and closest to the vehicle. In some embodiments, the server device 120 may determine a driving direction of the vehicle based on the above-described route information, and determine the first signal light based on the current location of the vehicle and the driving direction of the vehicle. In some embodiments, the server device 120 may use as the first signal a signal of an intersection located closest to the vehicle in front of the road and according to the current location of the vehicle (or road). Further, the server-side device 120 determines a group of signals including the first signal to determine other signals for which a green wave communication relationship exists. In some embodiments, the server-side device 120 may determine a signal that the vehicle passes after the first signal through route information of the vehicle (e.g., a planned route provided for the vehicle, a predicted vehicle travel route, etc.), and for ease of understanding, such a signal may be referred to as a second signal. Accordingly, the server device 120 may determine a second speed range corresponding to the second signal based on the location of the vehicle to the second signal, respectively.

For ease of understanding, only the example is illustrated in which the server-side device 120 determines a green wave speed range corresponding to the first signal light based on the distance of the vehicle from the first signal light. After determining the first signal, the server device 120 determines a distance between the vehicle and the first signal, a current state of the first signal, and a switching time of at least one future state, for example, the current state of the first signal is red, and a future green switching time is 10:10:15, the moment of switching yellow lamps by the green light in the future is 10:10:45, the time for switching the red light of the future yellow light is 10:10:50.

further, the server device 120 determines a speed range in which the first signal is in a green light state just when the vehicle reaches the first signal based on the switching timing and the distance of the vehicle to the first signal, for example, the server device 120 may determine the speed range [ v ] based on the following formulas (1) and (2) _min ,v _max ]：

Wherein D represents the distance from the current vehicle to the first signal lamp, t ₁ Indicating the end time of a green light period of the first signal lamp, t ₂ Representing the start time of this green light cycle of the first signal, T represents the point in time at which it is desired to enter the green wave traffic state (e.g., the current time at which the distance of the vehicle to the first signal is obtained), v _min Representing the lower limit of the velocity value, v _max Indicating an upper speed value limit.

ExampleFor example, the current vehicle is 200m away from the first signal lamp, and the time when the green wave passing state is expected to be entered is 10:10:05, the current state of the first signal lamp is red, and the green light in a future green light period is started as 10:10:15, the end time is 10:10:45. accordingly, the service end device 120 may determine that a green wave speed range corresponding to the first signal lamp isI.e. [5m/s,20m/s ]]。

Accordingly, the server-side device 120 may determine the speed range of the other lights than the first signal in the set of lights based on a similar manner.

It should be appreciated that for the same signal, the server device 120 determines a plurality of different speed ranges (e.g., for different green light periods, corresponding speed ranges are obtained).

Further, the server apparatus 120 may determine a green wave speed range corresponding to a group of signal lights including the first signal light based on the green wave speed range interval corresponding to each signal light. For ease of understanding, a green wave speed range corresponding to a set of signal lamps may be referred to as a target green wave speed range. In some embodiments, the server device 120 may perform statistics based on each signal in a set of signals (e.g., the green wave speed ranges corresponding to the first signal and the second signal) to determine an intersection of the green wave speed ranges corresponding to each signal, and use the intersection as the green wave speed range corresponding to the set of signals (i.e., the target green wave speed range described above).

In some embodiments, determining a green wave speed range for traveling through a group of lights including a first light includes: determining a first speed range for traveling through the first signal; determining at least one second speed range for driving through at least one second signal, the at least one second signal being determined based on route information of the vehicle; and determining a green wave speed range for traveling through a set of signal lights based on the first speed range and the at least one second speed range.

Specifically, as described above, the server device 120 may determine a first speed range corresponding to the first signal lamp (i.e., a green wave speed range corresponding to the signal lamp described above), and a second speed range corresponding to the at least one second signal lamp (i.e., a green wave speed range corresponding to the signal lamp described above), respectively (e.g., a signal lamp passing after the vehicle passes through the first signal lamp, determined based on the route information of the vehicle). The server device 120 then determines a green wave speed range (i.e., the target green wave speed range described above) for traveling through a set of signal lights based on the intersection between the first speed range and the second speed range. In some embodiments, the server-side device 120 may also filter the determined target green wave speed range based on a pre-maintained speed threshold in determining the target green wave speed range. For example, a speed threshold may be maintained based on information such as road speed limit, so that the server device 120 may delete (or modify) a speed range that does not meet the road speed limit according to the speed threshold, so that the final target green wave speed range meets the road speed limit requirement, and has practical use value.

It should be appreciated that, based on the foregoing description, the server device 120 may ultimately maintain at least one target green wave speed interval and a set of signal lights corresponding to the target green wave speed interval. For example, the server device 120 may maintain a set of lights (e.g., first light, second light a, second light b) corresponding to the target green wave speed interval [30km/h,40km/h ], and a set of lights (e.g., first light, second light a, second light b, and second light c) corresponding to the target green wave speed interval [30km/h,50km/h ].

It should be appreciated that in some scenarios, for example, the intersection of one or more green wave speed intervals corresponding to a first signal with one or more green wave speed intervals of other signals (e.g., a second signal) is an empty set, and accordingly, only the first signal may be included in such a set of signals.

To more clearly illustrate the results of this process, reference may be made to FIG. 3 for an exemplary purpose. An example 300 of the server device 120 determining a green wave speed range in some embodiments is shown in fig. 3. In fig. 3, a distance-time coordinate system may be constructed, and indication states of the respective signal lamps (e.g., the first signal lamp, the second signal lamp a, the second signal lamp b, and the second signal lamp c) are represented therein by a histogram. In example 300, the bar graph portion corresponding to pattern 310 indicates that the signal is in a red light state, the bar graph portion corresponding to pattern 320 indicates that the signal is in a green light state, and the bar graph portion corresponding to pattern 330 indicates that the signal is in a yellow light state. Example 300 illustrates one available speed (e.g., one available speed for vehicle 341 for line 351 shown) for each of the target green wave speeds of vehicle 341 and vehicle 342, and a corresponding green wave band width (e.g., time width 350 shown for vehicle 341) at that available speed.

At block 220, the server-side device 120 generates green wave alert information in response to determining that the current speed of the vehicle falls within the green wave speed range. In an embodiment of the present disclosure, the server device 120 presents green wave alert information with a target device associated with the vehicle (e.g., such a target device may be, for example, the terminal device 110 used by the user 130 in the case of the vehicle being driven by the user 130) if it is determined that the current speed of the vehicle falls within the above-determined green wave speed range. Such green wave alert information indicates at least one of: the green wave speed range and the number of a group of signal lights, i.e. the number of signal lights that the service end device 120 can use the terminal device 110 to present the green wave speed range in which the vehicle currently falls, and the number of signal lights that the green wave speed range can pass. Based on the above example, for example, in the case where the server device 120 determines that the current speed of the vehicle is 35km/h, it may be determined that it falls within the [30km/h,40km/h ] target green-wave speed section. Accordingly, the service-side device 120 determines that the green wave speed range indicated in the green wave alert information is [30km/h,40km/h ], and the number of the group of signal lights is 3 (i.e., the first signal light, the second signal light a, and the second signal light b). For another example, the server device 120 may determine that it falls within the [30km/h,50km/h ] target green wave speed interval in the case where it is determined that the current speed of the vehicle is 45 km/h. Accordingly, the service-side device 120 determines that the green wave speed range indicated in the green wave alert information is [30km/h,50km/h ], and the number of one group of signal lights is 4 (i.e., the first signal light, the second signal light a, the second signal light b, and the second signal light c).

For example, reference may be made to fig. 4. An example 400 of green wave alert information displayed in terminal device 110 in some embodiments is shown in fig. 4. In this example 400, the server device 120 may determine the first signal 420 and the second signal 430 (subsequent signal not shown) based on a navigation path (e.g., navigation path 440) of the vehicle 410. Further, the service-side device 120 determines that the current speed of the vehicle 410 is 45km/h, falls within the green wave speed range [30km/h,50km/h ] indicated in the determined green wave alert information, and determines that it can continuously pass through 4 signal lights. Accordingly, the server device 120 presents the green wave alert information 450 using the display interface 111 of the terminal device 110. The green wave alert message 450 includes at least a message 451 indicating a target green wave speed range and a message 452 indicating the number of signal lights.

In some embodiments, information 453 indicating the direction of progress and information 454 of the current speed may also be presented in the display interface 111 in order to better assist the user 130 in driving.

In some embodiments, generating the green wave alert information includes: determining a speed limit constraint associated with the vehicle; and generating green wave reminding information in response to the green wave speed range meeting the speed limit constraint.

In particular, the server-side device 120 may also maintain a limited speed limit constraint associated with the vehicle, such as a speed limit constraint associated with the vehicle type (e.g., car, truck). Accordingly, after determining the speed limit constraint associated with the vehicle (e.g., speed limit information of the road for a vehicle of the small car type), the server device 120 generates green wave alert information if the target green wave speed range meets the speed limit constraint. For example, the server device 120 may determine that the vehicle is a small car, for which the speed limit constraint on the traveled road is [30km/h,80km/h ]. Accordingly, for the target green wave speed range [30km/h,50km/h ], the server device 120 may determine that it meets the speed limit constraints associated with the vehicle, and the server device 120 may provide green wave alert information for the vehicle accordingly. As another example, if the target green wave speed range determined by the server device 120 is [90km/h,100km/h ], the server device 120 may determine that the target green wave speed range is [90km/h,100km/h ] has exceeded the speed limit constraint as [30km/h,80km/h ], and accordingly, the server device 120 does not provide the green wave reminding information for the vehicle any more, thereby avoiding misguidance of the user (or, avoiding erroneous driving behavior of the guiding user, such as avoiding that the vehicle speed of the guiding user exceeds the road speed limit), and improving the use value of the reminding information while guaranteeing the driving safety.

In some embodiments, generating the green wave alert information includes: determining a degree of congestion associated with the vehicle; and generating green wave reminding information in response to the congestion degree being less than the threshold degree. Specifically, the server device 120 may further obtain a congestion degree associated with the vehicle, for example, after determining a location where the vehicle is located, the server device 120 may determine, based on a road side device of a road segment associated with the location, traffic information of other vehicles, and the like, for example, an average speed of the vehicle, a density of the vehicle, and the like, and further determine the congestion degree associated with the vehicle. Further, the server device 120 generates green wave alert information if it determines that the congestion level meets the requirement (e.g., is less than the threshold level of congestion). Therefore, the traffic light anxiety of the user is reduced while the green wave reminding information is provided for the user in the congestion state (or in the case that the green wave state cannot be entered in the green wave speed range) so as to improve the use value of the green wave reminding information. Alternatively or additionally, after determining the congestion level associated with the vehicle, the server-side device 120 may also send a prompt message to other electronic devices in the vehicle if it is determined that the congestion level exceeds the threshold congestion level. For example, prompt information is sent to vehicle entertainment equipment, ventilation equipment, massage equipment and the like so as to start the electronic equipment to provide corresponding services for users, thereby the users are in the environment of being jammed and anxiety, and driving experience is improved.

In some embodiments, generating the green wave alert information includes: determining the state of a first signal lamp; and generating green wave reminding information in response to the first signal lamp being in a preset state indicating that the traffic is possible. Specifically, the server device 120 may determine whether to generate the green wave reminding information based on the indication state of the first signal lamp, for example, the server device 120 may generate the green wave reminding information when determining that the first signal lamp is green. Therefore, the passing experience of the user can be improved to a greater extent, and the user experience reduction caused by the fact that the user needs to match the green wave speed range in a obviously speed-reducing mode is avoided.

In some embodiments, the above process 200 may further include: acquiring the update speed of the vehicle; and responsive to the update speed not being within the green wave speed range, adjusting green wave alert information based on the type of vehicle. Specifically, the server-side device 120 may also continuously track the vehicle to determine a change in the speed of the vehicle. When the server device 120 determines that the speed of the vehicle changes, a certain adjustment is performed on the green wave reminding information.

In some embodiments, the adjustment policy for the green wave alert information may also be associated with the type of vehicle, e.g., where the vehicle is a service vehicle (e.g., a utility vehicle, a service vehicle), the server device 120 may adjust that the green wave speed alert information is no longer displayed, e.g., the green wave alert information 450 is no longer displayed. That is, in some embodiments, adjusting the green wave alert information based on the type of vehicle includes: and stopping providing the green wave reminding information in response to the vehicle serving the vehicle. To avoid problems with still providing it with green wave speed information, causing speed induction, in case the speed of the vehicle has left the target green wave speed range. Thereby, the safety and riding comfort of the vehicle are improved. In some embodiments, the server device 120 may also display only part of the content in the green wave speed reminding information, for example, replace the original green wave reminding information with the current state information, that is, only display the information 453 indicating the advancing direction and the information 454 indicating the current speed, for example, and not display the information 451 and the information 452 any more. Accordingly, the server device 120 may also provide the suggested speed to the user based on different adjustment policies, for example, changing the presentation style to a manner of making a speed suggestion, so as to implement a policy for differentiation for different types of vehicles, thereby improving the user experience.

In some embodiments, adjusting the green wave alert information based on the type of vehicle includes: and updating the green wave reminding information to indicate that the current speed of the vehicle is not in the green wave speed range. Specifically, as discussed above, the server device 120 may also update the green wave alert information to indicate that the current speed of the vehicle is not within the green wave speed range, so that the user may determine whether to enter the green wave speed according to the requirement. In some embodiments, the updated green wave alert information may give a value within a specific green wave speed range (e.g., specific [30km/h,40km/h ]), may give a speed difference between the green wave speed ranges closest to the current speed range (e.g., acceleration or deceleration of 5km/h may enter the green wave speed range), or may give only an adjustment direction of the speed (e.g., acceleration or deceleration may enter the green wave speed range). Thus, the user can make driving decisions in actual situations, and differentiated green wave reminding can be realized for the user in such a way.

Based on the foregoing, in some embodiments, to better assist the user in making driving decisions, the server device 120 may further provide the user with alert information indicating the switching time of the status of the signal lights, so that the user can determine the status of the signal lights (and the future switching time) based on the alert information to make decisions better.

For this, reference may be further made to fig. 5. Fig. 5 is a flow chart 500 of a process of providing handoff information in accordance with some embodiments of the present disclosure. Process 500 may be implemented at an appropriate electronic device or combination of electronic devices (e.g., terminal device 110 or a combination of terminal device 110 and server device 120 as shown in fig. 1). For ease of discussion, process 500 is described below with the combination of terminal device 110 and server device 120 as an example.

At block 510, the server device 120 obtains an updated location of the vehicle. In embodiments of the present disclosure, the server device 120 may continuously obtain the location of the vehicle, as discussed above, by way of, for example, passing through the terminal device 110 used with the user 130.

At block 520, the server-side device 120 determines a third signal associated with the vehicle based on the updated location. In an embodiment of the present disclosure, the server device 120 can determine a third signal associated with the vehicle based on the updated location obtained by way of the above-described block 510, such as the signal closest to the updated location of the vehicle described above. It should be appreciated that in some embodiments, such a third signal may also be a plurality, such as a signal closest to the updated location of the vehicle and a signal next to the signal closest to the updated location of the vehicle (e.g., a second signal following the first signal in the embodiment illustrated in FIG. 2 above). In some embodiments, determining a third signal associated with the vehicle includes: in response to obtaining navigation information associated with the vehicle, determining a third signal light associated with the vehicle based on the navigation information; or in response to not obtaining navigation information associated with the vehicle, determining a third signal light associated with the vehicle based on lane information indicated by the updated location and/or operational information of the vehicle.

Specifically, the server device 120 may determine the forward direction of the vehicle based on the navigation information associated with the vehicle, and thereby determine the third signal light in the forward direction of the vehicle. Alternatively or additionally, in the event that navigation information is not available for the vehicle (e.g., navigation is not used, the vehicle is in a cruise state), etc., the server device 120 may determine a third signal light associated with the vehicle according to lane information indicated based on the updated location and/or operation information of the vehicle as described above. For example, the server device 120 may determine that the vehicle is in a left turn lane based on the updated location and based on steering wheel operation information of the vehicle (e.g., incorporating the left turn lane) to determine that the third signal should be a signal at the front intersection indicating a left turn. Therefore, the signal lamp with the indication state having practical value for the user can be determined, information of the signal lamp can be acquired in advance, and valuable information is provided for the user.

Alternatively or additionally, the server device 120 may also continuously acquire lane information and/or operation information of the vehicle for determining the third signal lamp, so as to avoid the problem that the third signal lamp cannot be determined in the case of navigation failure caused by misoperation of a user, change of driving intention, and the like. Accordingly, the service end device 120 may also continuously acquire the lane information and/or the operation information of the vehicle for determining the third signal lamp, and use the same as the auxiliary information of the navigation information, so that the third signal lamp may be determined more accurately.

In block 530, the server device 120 provides, in response to obtaining the state switching time of the third signal lamp, first switching alert information regarding the state switching time based on the current time and the state switching time of the third signal lamp. In an embodiment of the present disclosure, the server device 120 may provide first switching alert information about a state switching time (such a state switching time may be maintained in the server device 120 in advance, for example, a signal light state switching period provided by a traffic management department, and the signal light state switching period obtained based on image data mining captured by other vehicles) based on the state switching time of the third signal light, and present the first switching alert information with the terminal device 110 used by the user 130 (for example, with the display interface 111 associated with the terminal device 110), so that the user knows the switching time of the signal light ahead. In some embodiments, the state switch time comprises: the red light state is switched to the green light state or the green light state is switched to the yellow light state. The server device 120 may generate the first switching reminder information based on switching moments of the states of the signal lamps maintained in advance. The first switching reminding information may be at least a future state of the signal lamp switching and a time, for example, the first switching reminding information may be that the third signal lamp is switched from a green lamp state to a yellow lamp state at a ratio of 10:30:05.

For example, reference may be made to fig. 6. Fig. 6 illustrates an example 600 of displayed handoff alert information according to some embodiments of the present disclosure. In fig. 6, the server device 120 may determine a third signal light (e.g., traffic light 630) based on the updated location of the vehicle 610. Further, the server device 120 may present the first switching reminding information 640 by using the display interface 111, where the first switching reminding information 640 includes information 641 for informing the user of the specific third signal lamp indicated, information 642 for indicating the state of the third signal lamp, and information 643 for indicating the switching time of the future state of the third signal lamp. In some embodiments, for the convenience of the user to know the current state of the vehicle, the first switching reminding information 640 may further include information 644 for indicating the driving direction of the vehicle and information 645 for indicating the current time. In some embodiments, the first switching reminding information may further include a distance from the indicated third signal lamp to the update location. Therefore, the user can know the indication state of the front traffic light and the switching time of each state based on the first switching reminding information, so that the user can conveniently make decisions by combining with the self requirements.

In some embodiments, for the timing of acquiring the update location, the server device 120 may periodically acquire the update location, or may acquire the update location if it determines that the vehicle passes through a signal light, or may communicate with the user 130 in advance, so as to control the terminal device 110 used by the user 130 to send a corresponding update indication if it determines that the user 130 (or the vehicle driven by the user 130) passes through the signal light. Thus, the server device 120 may continuously acquire the status of the signal in the future in case that it is determined that the user 130 passed the previous signal, so as to continuously provide the status of the signal to the user.

Alternatively or additionally, the server device 120 may also determine whether the distance from the next signal (i.e., the third signal) falls within a reminding distance (e.g., such a reminding distance may be 150 m) if the user 130 passes through the previous signal, and perform reminding again if it is determined that the user 130 falls within the reminding distance, so as to avoid reminding the user prematurely, which may cause anxiety to the user.

In some embodiments, providing the first handoff alert information includes: presenting a path element associated with the vehicle, the path element being associated with a signal element corresponding to the third signal; and in response to the third signal light switching to the green light state, changing the presentation style of the path element to dynamically indicate the green light state of the third signal light. Specifically, in the case where the server device 120 presents the first switching alert information to the user 130 by using the terminal device 110, the presented content (for example, the indication state of the third signal light, etc.) may also be associated with a path element (for example, an earthworm line for guiding the vehicle to advance), so as to present the indication state of the third signal light, for example, to the user more concisely and intuitively. For example, in the case where the server device 120 presents the first switching alert information to the user 130 using the terminal device 110, the server device 120 associates the third signal with a presentation style that may select a path element corresponding to, for example, between the third signal location and the updated location of the vehicle (or between the third signal location and the updated location of the vehicle, which is within a preset distance from the third signal location).

For example, reference may be continued to FIG. 6. In fig. 6, the server device 120 may display the path element described above with the second presentation style 660 to present a third signal light (e.g., traffic light 630) in front of a vehicle (e.g., vehicle 610) in a green light state. In some embodiments, the server device 120 may also configure different presentation styles according to different indication states, e.g., the server device 120 may configure the traffic light 630 with a first presentation style 650 associated with a red light. Accordingly, the server device 120 uses the first presentation style to present the path element, so as to inform the user that the current indication state of the third signal lamp is red. Thus, the user is informed of the change of the indication state of the third signal lamp more intuitively in a manner of switching the style (for example, a manner of switching the first presentation style to the second presentation style).

In some embodiments, the second presentation style 660 may also have dynamic effects, such as continuous motion arrows, whereby such second presentation style 660 may also intuitively indicate the direction of travel of the vehicle at the same time, for easier understanding by the user.

In some embodiments, further comprising: acquiring an image of the third signal lamp by using image acquisition equipment carried by the vehicle in response to the condition switching moment of the third signal lamp not being acquired; based on the image, determining that a third signal lamp is subjected to preset state switching; and providing a second switching reminding information about the state switching. Specifically, in the case where the state switching timing of the third signal lamp is not acquired, the server device 120 may acquire an image of the third signal lamp using the image acquisition device in which the vehicle is. It should be appreciated that, in acquiring an image of the third signal with the image capturing device of the vehicle, the server device 120 may also communicate with other vehicles associated with the location of the third signal (e.g., reference vehicles located within a certain distance of the third signal) using, for example, positioning information, to acquire an image of the third signal with the image capturing device of the reference vehicle. Further, the server device 120 provides the second switching reminding information about the state switching in the case that it is determined that the third signal lamp is subjected to the preset state switching based on the image. Therefore, the situation that the state switching time (for example, the state switching time cannot be acquired) cannot be based on the state switching time can be avoided, and the service can be provided for the user by using other vehicles in a scene, image acquisition equipment of the vehicles and the like, so that the stability is enhanced, and the service quality is improved.

In some embodiments, the generation of the first switching alert information is further based on user configuration information associated with the vehicle, wherein the user configuration information includes at least one of: the type of state switching for the first switching reminding information, the visual style of the first switching reminding information and the voice template of the first switching reminding information. In particular, to better conform to the needs of the user, a personalized experience is provided for the user, and the user may also configure the parameters of the first switching prompt information in advance, for example, the user may configure the type of state switching targeted in the first switching prompt information (for example, only providing red light to switch green light, green light to switch red light, red and green light to switch, whether yellow light to switch, etc.), each indicating a corresponding visual pattern (e.g., text display, graphic display, and font, size of text, the graphic style employed in the graphic display, for example, the image style may have a special style corresponding to a specific time, for example, in the case of a scenario, the graphic style may be a "heart shape"), the visual style of the first switching reminder information, whether the first switching reminder information is allowed to be prompted in the form of voice, and a voice template of the first switching reminder information (for example, one of the pre-configured voice templates is selected, or a user-customized entered voice template, etc.), and so forth. Accordingly, the server device 120 may generate the first switching reminding information according to the above configuration of the user, so as to obtain the first switching reminding information meeting the user requirement, thereby improving the user experience.

Alternatively or additionally, in some embodiments, in the case of providing the first switch alert information to the user, different presentation effects may also be provided to the user based on different state switch combinations (e.g., red to green and green to red may have different presentation effects), e.g., the information (e.g., information 642) indicating the status of the signal may be highlighted (e.g., flashing, magnifying, etc.) for the user for a certain period of time (e.g., within the last 3 seconds) to alert the user to prepare for a corresponding action (e.g., vehicle launch, etc.).

Based on the above-described process, the embodiment of the disclosure may determine the green wave speed range, and then perform green wave reminding after the vehicle speed falls into the green wave speed range, so as to avoid speed guidance for the user, and avoid the user adapting to the green wave speed in a frequent acceleration and deceleration manner. Therefore, the green wave information can be provided to improve the passing efficiency, and the driving comfort and safety can be ensured.
