Description

  The present invention relates to a navigation system.

  In a navigation system that provides navigation to a driver who drives a vehicle, the driver's life information related to vehicle driving is registered in a pattern, and a predicted departure time and a destination are obtained based on the registered life information. A technique for transmitting traffic jam information together with a destination is known (see Patent Document 1 below).

JP 2005-181241 A

  By the way, the vehicle may be used exclusively by one person, but may be shared by a family member, for example. In a shared house such as a condominium, a vehicle may be shared by residents living in the shared house. Thus, the case where one vehicle is shared by a plurality of drivers can be considered.

  Here, according to the technique described in Patent Document 1, since it is not considered to share a vehicle by a plurality of drivers, it is not possible to provide appropriate navigation for each driver.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a navigation system capable of providing appropriate navigation for each driver when a vehicle is shared by a plurality of drivers.

  The navigation system of the present invention includes an imaging unit that images a driver in a vehicle, a specifying unit that specifies a face authentication image of the driver from an image captured by the imaging unit, and a face authentication of the driver specified by the specifying unit Based on the driving information stored in the driving information storage means in association with the image, driving information storage means for storing driving information including the departure time, travel route, destination and arrival time of the vehicle driven by the driver Analyzing means for analyzing a driving pattern including a predicted departure time, a predicted travel route, a predicted destination, and an estimated arrival time for each driver, and acquiring means for acquiring traffic information including a traffic jam section Extracting means for extracting the driving pattern including a traffic jam section included in the traffic jam information when the traffic jam information is acquired by the acquisition unit; Predicted travel route to the predicted destination to the destination information processing device specified in advance by the driver before the predicted departure time specified by the driving pattern including the traffic jam section extracted by the extracting means Transmission means for transmitting attention information indicating that a traffic jam has occurred.

  According to the navigation system configured as described above, when a vehicle is shared by a plurality of drivers, appropriate navigation can be provided for each driver.

  In the navigation system, the traffic jam information may include a traffic jam section where the traffic jam occurs and a delay time delayed due to the traffic jam, and the caution information may include the traffic jam section and the delay time.

  As a result, the navigation system can navigate the traffic jam section and the delay time due to the traffic jam to the driver.

  Furthermore, the navigation system creates a plurality of travel routes to the predicted destination included in the driving pattern, and until the predicted destination is reached for each of the plurality of travel routes created by the creation unit. A time predicting means for predicting a time required for the time, and the transmitting means selects a travel route corresponding to the longest predicted time among the predicted times for each of the plurality of travel routes predicted by the time predicting means. And even if it uses the selected driving | running route, you may make it transmit the said attention information to the said information processing apparatus at the time in time for the said estimated arrival time.

  Further, the transmission unit may transmit the plurality of routes and the predicted time in the attention information.

Then, the information processing device displays a display that displays a receiving unit that receives the attention information, and the traffic jam section, a delay time, the plurality of travel routes, and the predicted time included in the attention information received by the receiving unit. Thus, the navigation system can notify the driver that a traffic jam has occurred before the latest arrival time at the destination.

  Furthermore, the display means may display the travel route having the shortest predicted time among the plurality of travel routes so that the travel route can be distinguished from other travel routes.

  Thereby, the navigation system can display the caution information so that the driver can visually recognize the route arriving at the earliest destination at a glance.

  The navigation system includes a server capable of communicating with the vehicle, the vehicle includes the imaging unit, the specifying unit, and the driving information storage unit, and the server includes the acquisition unit, the extraction unit, You may make it provide an analysis means and the said transmission means.

  As a result, the server can execute processing with heavy load such as analysis of driving information, and the processing load on the control unit of the vehicle can be reduced.

  Furthermore, when the navigation system is configured as described above, the vehicle may transmit the driving information stored in the driving information storage unit when receiving an instruction to transmit the driving information from the server.

  As a result, the server can execute processing for acquiring driving information of the vehicle when its own load is light. For example, when obtaining driving information from many vehicles, the load can be distributed, which is particularly effective.

  The vehicle may include the imaging unit, the specifying unit, the driving information storage unit, the acquisition unit, the extraction unit, the analysis unit, and the transmission unit.

  Thereby, since the driving information of the vehicle and the face authentication information of the driver are not output outside the vehicle, it becomes possible to protect the privacy of the driver driving the vehicle.

  Furthermore, a traffic information providing system for managing traffic information including traffic jam information related to roads may be provided, and the acquisition means may acquire the traffic jam information from the traffic information provision system.

  According to the present invention, when a vehicle is shared by a plurality of drivers, it is possible to provide appropriate navigation for each driver.

  As described above, the server 200 can manage the driving information of the plurality of vehicles 100 for each vehicle 100.

  FIG. 8 is a diagram for explaining a specific example of an analysis method in which the server 200 analyzes driving information to obtain a driving pattern and a driving pattern (analysis result).

  For example, it is assumed that the contents of the driving information M11 to M15 are the following contents as shown in FIG.

  The driving information M11 includes the departure position (XXXXX), departure time (2015/11/09 MON 08:15:05), travel route (section A, section C, section D, section F, section H), arrival It is the time (2015/11/09 MON 08:45:15) and the destination (XX Automobile Industry Co., Ltd. xx establishment).

  Driving information M12 includes departure position (XXXXX), departure time (2015/11/10 TUE 08:16:06), travel route (section A, section C, section D, section F, section H), arrival The time (November 09, 2015 TUE 08:48:15) and the destination (XX Auto Industry Co., Ltd. × Office).

  Driving information M13 includes departure position (XXXXX), departure time (2015/11/11 WED 08:16:05), travel route (section A, section C, section D, section F, section H), arrival The time (November 11, 2015 WED 08:45:45) and the destination (XX Auto Industry Co., Ltd. xx establishment).

  Driving information M14 includes departure position (XXXXX), departure time (2015/11/12 THU 08:15:25), travel route (section A, section C, section D, section F, section H), arrival It is the time (2015/11/09 THU 08:45:49) and the destination (XX Automobile Industry Co., Ltd. xx establishment).

  Driving information M15 includes departure position (XXXXX), departure time (2015/11/13 FRI 08:14:15), travel route (section A, section C, section D, section F, section H), arrival It is the time (2015/11/13 FRI 08:45:17) and the destination (XX Automobile Industry Co., Ltd. xx establishment).

  When analyzing the driving information M11 to M15, the controller 210 starts from Monday to Friday (XXX), travel route (section A, section C, section D, section F, section H), destination (○ ○ Automobile industry Co., Ltd. xx establishments) is the same, and it is analyzed that driving information is not stored on Saturday and Sunday.

  Further, the control unit 210 analyzes that the driver is using the vehicle 100 for commuting, considering that the destination is in the office. Further, the control unit 210 analyzes that the departure time is approximately 8:15 and the arrival time is approximately 8:45.

  Therefore, the control unit 210 sets the predicted departure position (XXXXX), predicted departure time (MON-FRI 08:15:00), and predicted travel route (section A, section C, section D, section as the driving pattern P1. F, section H), predicted arrival time (MON-FRI 08:45:00), and predicted destination (XX Automobile Industry Co., Ltd. × XX office) are analyzed, and the operation pattern P1 is stored in the analysis result storage unit 260. Remember. The driving pattern P1 is associated with a vehicle body ID, a driver ID, and a mail address.

  Next, processing for setting an e-mail address from which the driver receives attention information will be described. FIG. 9 is a flowchart illustrating an example of processing for setting a mail address for the control unit 110 to receive attention information.

  A driver located in the driver's seat of vehicle 100 operates touch panel 160 to start a mail address setting operation. Thereby, control unit 110 accepts a mail address setting operation from the driver (ST101).

  Next, the control unit 110 operates the imaging unit 120 (ST102). The imaging unit 120 images a driver's face located in the driver's seat. The image processing unit 121 performs face authentication processing on the image captured by the imaging unit 120. The face authentication information at this time becomes the driver ID of the driver.

  Next, control unit 110 displays the driver ID (face authentication information) captured on touch panel 160 (ST103). Based on the image displayed on the touch panel 160, the driver determines whether or not his / her face has been photographed, and inputs OK or NO to the touch panel 160.

  Based on the driver input, control unit 110 determines whether or not it is OK (ST104). If it is determined that it is not OK (that is, NO) (ST104: NO), the process returns to step ST101 and the process is repeated.

  If it is determined that it is OK (ST104: YES), control unit 110 accepts input of a mail address of a destination of attention information desired by the driver (ST105).

  Next, based on the driver's input operation on touch panel 160, control unit 110 determines whether or not the process is terminated (ST106). When it is determined that the process is not finished (ST106: NO), the process of accepting the mail address is continued.

  On the other hand, if it is determined that the process is finished (ST106: YES), control unit 110 stores the received mail address in the mail address storage unit 184 in association with the driver ID (ST107).

  Next, the control unit 110 associates the vehicle body ID stored in the vehicle body ID storage unit 181 with the mail address stored in the mail address storage unit 184 and the driver ID, and transmits the associated information to the server 200. (ST108). Then, the mail address setting process ends.

  When the server 200 receives information associated with the vehicle body ID, the mail address, and the driver ID from the vehicle 100, the server 200 refers to the entire driving information storage unit 240, and obtains the vehicle body ID and the driver ID from the data D2 (refer to FIG. 7). The mail address is stored in association with the vehicle body ID and the driver ID. When the vehicle body ID and the driver ID are not found, the control unit 210 adds the vehicle body ID, the mail address, and the driver ID to the data D2. In the present embodiment, a case where one email address is registered in association with the driver ID will be described. However, two or more email addresses may be registered, and the email address is changed based on the operation of the touch panel 160 of the driver. It is also possible.

  Next, a process for storing driving information when the driver drives the vehicle 100 will be described. FIG. 10 is a flowchart illustrating an example of processing in which the control unit 110 stores driving information.

  As shown in FIG. 10, first, control unit 110 determines whether or not the vehicle is activated (ST201). In the present embodiment, the control unit 110 determines whether or not the switch 111 is turned on by the driver. If it is determined that the vehicle is not activated (ST201: NO), the process returns to step ST201, and control unit 110 continues the standby state.

  When it is determined that the vehicle is activated (ST201: YES), the control unit 110 operates the imaging unit 120 (ST202: imaging unit). As a result, the face of the driver located in the driver's seat is photographed, and the driver ID (face authentication information) is acquired.

  Next, the control part 110 specifies a driver (ST203: specifying means). More specifically, the control unit 110 compares the driver ID (face authentication information) acquired in step ST202 with the driver ID (face authentication information) stored in the driving information storage unit 183, and determines the driver. Identify. Note that if there is no matching driver ID in the driving information storage unit 183, for example, in the case of a driver driving the vehicle 100 for the first time, the control unit 110 associates the driver ID and the vehicle body ID acquired this time with the driving information storage unit 183. To remember.

  Next, control unit 110 stores the departure position and departure time (ST204). Specifically, the control unit 110 identifies the departure position based on the position acquired by the position information acquisition unit 130 and the map acquired by the map information acquisition unit 140, and associates the departure position with the driver ID. And stored in the driving information storage unit 183. In addition, the control unit 110 identifies the date and the current time based on the date and time acquired from the clock unit 150, and uses the identified date and current time as the departure time in association with the driver ID and the departure position. The information is stored in the information storage unit 183.

  Next, control unit 110 stores the travel route of vehicle 100 (ST205). Based on the position acquired by the position information acquisition unit 130 and the map acquired from the map information acquisition unit 140, the section in which the vehicle 100 travels is specified, and the traveled section is associated with the driver ID in time series. The information is stored in the information storage unit 183. For example, the control unit 110 stores the driving section in the driving information storage unit 183 in association with the driver ID when the driving of the preset section is completed while driving on the road. Here, the section is set so as to correspond to the section when the traffic information providing system 400 provides the traffic jam information.

  Next, control unit 110 determines whether or not vehicle 100 is stopped (ST206). This determination is not a temporary stop of the vehicle 100 but a determination as to whether or not the vehicle 100 has arrived at the destination. Therefore, the control unit 110 performs the determination in step ST206 depending on, for example, whether or not the switch 111 is turned off. If it is determined that vehicle 100 is not stopped (ST206: NO), the process returns to step ST205. Thus, the travel route until the vehicle 100 stops is sequentially stored for each section.

  On the other hand, when determining that vehicle 100 has stopped (ST206: YES), control unit 110 stores the arrival position and the arrival time (ST207). Specifically, the control unit 110 identifies the arrival position based on the position acquired by the position information acquisition unit 130 and the map acquired from the map information acquisition unit 140, and uses the arrival position as the driver ID. The associated information is stored in the driving information storage unit 183. In addition, the control unit 110 identifies the date and the current time based on the date and time acquired from the clock unit 150, and uses the identified date and current time as the arrival time in association with the driver ID and the arrival position. The information is stored in the information storage unit 183. As a result, the driving information of the current driver is stored in the driving information storage unit 183. The storage means of the present invention is configured by steps ST204 to ST207.

  Next, the control unit 110 transmits information (hereinafter referred to as transmission information) in which the vehicle body ID, the driver ID, and the driving information stored in the current driving information storage unit 183 are associated with each other to the server 200 (ST208). And the control part 110 complete | finishes a process.

  Accordingly, the server 200 can acquire transmission information, that is, information associated with the driving information, the vehicle body ID, and the driver ID from each vehicle 100 each time the plurality of vehicles 100 are driven. Become.

  Next, processing when server 200 receives transmission information from vehicle 100 will be described. FIG. 11 is a flowchart illustrating an example of processing executed when the control unit 210 receives transmission information from the vehicle 100.

  As shown in FIG. 11, first, control unit 210 determines whether or not transmission information has been received from vehicle 100 (ST301). If it is determined that the transmission information has not been received (ST301: NO), the process returns to step ST310 and the standby state is continued.

  On the other hand, if it is determined that the transmission information has been received (ST301: YES), the control unit 210 searches the vehicle ID and driver ID included in the transmission information from the entire driving information storage unit 240, and searches for the vehicle ID, The driving information included in the transmission information is stored in the total driving information storage unit 240 in association with the driver ID (ST302). When the vehicle ID and the driver ID cannot be searched, the control unit 210 newly stores the vehicle ID and the driver ID in the all driving information storage unit 240, and stores the newly stored vehicle ID and driver ID in the newly stored vehicle ID and driver ID. The driving information is stored in the total driving information storage unit 240 in association with each other.

  Next, control unit 210 performs driving information analysis processing on the vehicle ID and driver ID to which driving information has been added in step ST302 (ST303: analysis means). Here, the analysis process is, for example, analyzing the driving pattern of the driver based on the driving information accumulated in the past and the driving information newly stored this time. A specific example of the analysis process has already been described with reference to FIG.

  Next, control unit 210 stores an operation pattern, which is an analysis result of the analysis process, in analysis result storage unit 260 (ST304). Then, the control unit 210 ends the process.

  As described above, each time the server 200 receives transmission information from the vehicle 100, the server 200 executes analysis processing using the newly received driving information. Therefore, the driving pattern based on the latest driving behavior of the driver is stored as an analysis result. It can be stored in the unit 260.

  Next, processing when the server 200 receives traffic jam information from the traffic information providing system 400 will be described. FIG. 12 is a flowchart illustrating an example of processing executed by the control unit 210 when traffic jam information is received.

  As shown in FIG. 12, first, the control unit 210 determines whether or not traffic information has been received from the traffic information providing system 400 (ST401: acquisition unit). If it is determined that the traffic jam information has not been received (ST401: NO), the process returns to step ST401.

  On the other hand, when determining that the traffic jam information has been received (ST401: YES), control unit 210 acquires the traffic jam section and the delay time from the received traffic jam information (ST402).

  Next, the control unit 210 extracts, from the driving pattern stored in the analysis result storage unit 260, the vehicle 100 predicted to travel in the traffic jam section by the traffic jam resolution prediction time when the traffic jam of the traffic jam section is resolved ( ST403: Extraction means).

  More specifically, for example, the control unit 210 first calculates a traffic jam resolution predicted time by using the delay time included in the traffic jam information and the time acquired from the clock unit 230. Next, the control unit 210 extracts from the analysis result storage unit 260 a driving pattern in which a traffic jam section is included in the predicted travel route before the traffic jam resolution prediction time elapses. In the present embodiment, the case where the server 200 predicts the traffic jam prediction elimination time will be described. However, the traffic jam information may be configured to include the traffic jam elimination prediction time.

  Next, control unit 210 selects one operation pattern from the extracted operation patterns (ST404). The operation pattern extraction method is arbitrary.

  Next, control section 210 creates a plurality of different routes to the destination included in the driving pattern (ST405: creation means). For example, the control unit 210 excludes a traffic jam section, further excludes a traffic jam section specified by other traffic jam information from the travel route, and travels between the departure point and the destination included in the extracted driving pattern. A plurality of routes are created, and a plurality of travel routes are selected from the travel routes that satisfy predetermined conditions such as the total distance of the travel routes and whether or not a section of the main road is included. For example, the control unit 210 selects in order from a travel route having a section of a main road and having a short total distance. Thereby, it becomes possible to select a travel route in order of short travel time.

  Next, the control unit 210 predicts the time required to reach the destination when each route is used (ST406: time prediction means).

  Next, the control unit 210 sets the time required for the longest time from the predicted required time as the transmission advance time, sets the time before the transmission advance time as the caution information transmission time from the predicted departure time, and sets the vehicle body ID, driver The contents of the caution information including the ID and mail address are determined (ST407).

  Next, control section 210 determines whether or not all the extracted operation patterns have been selected (ST408). If it is determined that not all driving patterns have been selected (ST408: NO), the process returns to step ST404, and if it is determined that all driving patterns have been selected (ST408: YES), the process ends. In this way, attention information is created every time traffic information is received.

  Next, a process in which the server 200 transmits attention information to the information processing apparatus 300 will be described. FIG. 13 is a flowchart illustrating an example of a process in which the control unit 210 transmits attention information to the information processing apparatus 300.

  As shown in FIG. 13, control unit 210 obtains the current time from clock unit 230 (ST501).

  Next, control section 210 determines whether there is attention information that has reached the attention information transmission time (ST502). In other words, the control unit 210 determines whether there is caution information whose caution information transmission time included in the caution information matches the acquired current time.

  If it is determined that there is no caution information at the caution information transmission time (ST502: NO), the process returns.

  On the other hand, when it is determined that there is attention information that has reached the attention information transmission time (ST502: YES), control unit 210 transmits the attention information that has reached the attention information transmission time to information processing device 300 (ST503: transmission means). ), Processing is a return. In the present embodiment, the caution information is transmitted to an e-mail address included in the caution information.

  Next, processing of the information processing apparatus 300 when attention information is received will be described. FIG. 14 is a flowchart illustrating an example of processing executed when the control unit 310 receives attention information.

  As shown in FIG. 14, control section 310 determines whether or not attention information has been received (ST601: receiving means). If it is determined that attention information has not been received (ST601: NO), the process returns to step ST601, and control unit 310 continues the standby state.

  On the other hand, when it is determined that attention information has been received (ST602: YES), control unit 310 stores the received attention information in memory 360 (ST602).

  Next, control section 310 displays attention information reception on notification section 340 (ST603). For example, the control unit 310 displays a message “congestion has occurred” on the notification unit 340. A predetermined sound (ringing tone) may be output from the notification unit 340 together with the display of this message.

  Next, when control unit 310 receives an instruction to display attention information from driver via touch panel 330 (ST604), control unit 310 displays the attention information on touch panel 330 (ST605: display means).

  Next, control section 310 determines whether or not a predetermined instruction has been received via touch panel 330 (ST606). When it is determined that the predetermined instruction has not been received via the touch panel 330 (ST606: NO), the attention information display process is continued. On the other hand, when it is determined that the predetermined instruction has been received via touch panel 330 (ST606: YES), control unit 310 ends the display process of the caution information.

  Next, a display example of the caution information displayed on the touch panel 330 will be described. FIG. 15 is a diagram illustrating an example of the touch panel 330 displaying attention information.

  As shown in FIG. 15, the display example 330a of the touch panel 330 shows a plurality of routes (traveling routes) R1 to R4 from the departure point S to the destination G.

  The route R1 is a travel route included in the driving pattern P1, and the routes R2 to R4 are travel routes created by the server 200. Further, in route R1, a traffic jam section on the travel route is shown. As a result, the driver can visually recognize the traffic jam at a glance.

  Also, at the bottom of the map showing routes R1 to R4, the departure time (MON-FRI 08:15), arrival time (MON-FRI 08:45), and required time (30 minutes) of the driver's driving pattern are shown. It is displayed. The departure time and arrival time displayed in this display example 330a reflect the estimated departure time and the estimated arrival time, respectively.

  Furthermore, on the lower side, the required time from the route R2 to the route R4, the required time according to the route, and the time to depart early are displayed. For route R2, the required time is 35 minutes, so it is necessary to depart 5 minutes earlier, for route R3, the required time is 40 minutes, and it is necessary to depart 10 minutes earlier, and for route R4 Indicates that it is necessary to depart 20 minutes earlier because the required time is 50 minutes.

  Further, the route R2 is displayed so as to be distinguishable from the other routes R3 and R4. For example, the route R2 is displayed by highlighting or highlighting. For this reason, the driver can visually recognize at a glance the route (route R2) that arrives at the destination in the shortest time among a plurality of other proposed routes (routes R2 to R4).

  Further, the current time (in this embodiment, the same time as the mail reception time) is displayed on the upper side of the map showing the routes R1 to R4. 7:55 is displayed as the current time. Therefore, the driver can arrive at the destination at 8:45 even when using the route 4 having the longest time to the destination G of 50 minutes. That is, the driver is informed that a traffic jam has occurred before the latest arrival time at the destination G using the route R4.

  As described above, when the navigation system N shares the vehicle 100 with a plurality of drivers, the driver can transmit the attention information to the information processing apparatus 300 set as the transmission destination of the e-mail by the driver. Appropriate navigation can be provided for each.

  In the navigation system N, the vehicle 100 executes the processing of step ST202 (imaging unit), step ST203 (identification unit), and steps ST204 to ST207 (driving information storage unit), and the server 200 performs step ST401 (acquisition). Means), step ST403 (extraction means), step ST303 (analysis means), and step ST503 (transmission means). For this reason, the server 200 can execute processing with heavy loads such as analysis of driving information, and the processing load on the control unit 110 of the vehicle 100 can be reduced.

  Further, when the navigation system N is configured as described above, the control unit 110 of the vehicle 100 transmits the previous driving information when receiving an instruction to transmit the driving information from the server 200, and then stores the driving information in the driving information storage unit 183. You may make it transmit the memorize | stored driving information at once.

  If comprised in this way, the server 200 will be able to perform the process which acquires the driving information of the vehicle 100, when own load is light. For example, when driving information is acquired from many vehicles 100, the load can be distributed, which is particularly effective.

(Second Embodiment)
The second embodiment differs from the first embodiment in that the server 200 is not provided in the navigation system N as shown in FIG.

  Furthermore, as shown in FIG. 17, an analysis program storage unit 250 and an analysis result storage unit 260 provided in the server 200 are provided in the vehicle 100. For this reason, vehicle 100 does not execute the process of transmitting transmission information to server 200 (reference: step ST208 in FIG. 10). Further, the processing from step ST302 to step ST304 (refer to FIG. 11) executed by the server 200 is executed each time the control unit 110 of the vehicle 100 stores the driving information in the driving information storage unit 183, and the traffic information providing system 400. The control unit 110 executes the processing from step ST401 to step ST408 (refer to FIG. 12) and the processing from step ST501 to step ST503 (refer to FIG. 13). It has become.

  The vehicle 100 configured as described above can achieve the same effects as the navigation system N of the first embodiment.

  In addition, since the caution information can be transmitted to the information processing device 300 by the processing of the vehicle 100 without using the server 200, the introduction of the navigation system can be facilitated. Since the driver's face authentication information is not output outside the vehicle 100, the privacy of the driver driving the vehicle 100 can be protected.

  In the first and second embodiments described above, the case where the attention information once created is transmitted when the attention information transmission time comes has been described. However, the present invention is not limited to this. For example, when the created caution information is not transmitted to the set destination (before the caution information transmission time), the server 200 receives traffic information including a section specified by the caution information. In such a case, the created traffic information may be created (updated) again. Thereby, the caution information including a plurality of routes created based on the latest traffic jam information can be transmitted to the information processing apparatus 300.

  In addition, when the information in which the traffic jam in the traffic jam section is resolved is received from the traffic information providing system 400, the server 200 or the vehicle 100 deletes the caution information created based on the traffic jam information including the traffic jam section. Anyway.

  In the first and second embodiments described above, the case where attention information (first attention information) is transmitted when a traffic jam occurs has been described. However, the present invention is not limited to this case. The caution information (second caution information) may be transmitted in time for the normal departure time. FIG. 18 is a diagram illustrating an example of a display example 330b when the information processing apparatus 300 displays the second attention information. As described above, when the server 200 or the vehicle 100 has not received the traffic jam information from the traffic information providing system 400, the second warning information is transmitted to the information processing device 300 possessed by the driver, and the traffic jam information is received. If there is, the first attention information may be transmitted to the information processing apparatus 300 possessed by the driver. This allows the driver to receive caution information before the normal departure time when there is no traffic jam, and to receive the caution information a predetermined time before the normal departure time when there is a traffic jam. it can.

  Furthermore, in the first and second embodiments, the time before the transmission time before the departure time is set as the caution information transmission time. However, the setting of the caution information transmission time is not limited to this. Absent. For example, a time that is a predetermined time before the transmission time before the departure time may be set as the attention information transmission time. As a result, when heading to the destination by another route, the driver becomes a travel route that travels for the first time, and thus the vehicle 100 can be driven with peace of mind because it can depart at an earlier time. Here, the predetermined time may be set as a default, for example, 5 minutes, or may be set in the server 200 by the driver using the touch panel 160 of the vehicle 100. The predetermined time set by the driver may be stored in association with the driver ID.

  Furthermore, in the first and second embodiments, every time driving of the vehicle 100 ends, the vehicle 100 stores driving information in the driving information storage unit 183, and further, based on the stored driving information, driving is performed. Although described in the case of creating a pattern, it is not limited to this. For example, a driving pattern may be created based on driving information for one day at a predetermined daily time.

  The present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the above-described embodiments. For example, you may delete some components from all the components shown by embodiment mentioned above. Furthermore, you may combine the structure of different embodiment.
