First embodiment
Fig. 1 is a flowchart illustrating steps of a real-time road condition navigation method according to a first embodiment of the present invention. The method can obtain a proper navigation route without congestion, and improve driving safety, and referring to fig. 1, the real-time road condition navigation method of the embodiment may include the following steps 101-104.
Step 101, acquiring current position information and destination information of a vehicle, and obtaining an initial navigation route of the vehicle from the current position to a destination according to the current position information and the destination information of the vehicle.
In this step, the current position information of the vehicle, such as the position information of longitude and latitude of the vehicle, may be obtained in real time through the vehicle-mounted navigation system, and the destination information of the vehicle (such as the position information of longitude and latitude) input by the driver may be received, and then the initial navigation route between the vehicle from the current position to the destination may be obtained according to the current position information of the vehicle, the destination information and the pre-stored electronic map data. The initial navigation route is a complete route from the departure place to the destination, and the initial navigation route can comprise a plurality of road sections, wherein a driving road between every two adjacent traffic light intersections is a road section.
The electronic map data may be stored in the vehicle navigation system in advance, and may include road segment parameters, where the road segment parameters may include at least one of longitude, latitude, intersection position, and entrance-available position of a road segment. The drivable entry site may include at least one of a parking lot, a gas station, a residential area, and the like, which are non-public road areas. The road segment parameters may also include at least one of the parameters of the road segment's street, roadway, building, etc.
Step 102, obtaining the road condition of the navigation route in real time during the running process of the vehicle along the current navigation route, if knowing that the congestion condition occurs in the front (for example, the front or the front road section of the current road section), judging whether the current road section has a drivable place, if judging that the current road section has the drivable place, proceeding to step 103, preferably, if judging that the current road section does not have the drivable place, proceeding to step 102, wherein the drivable place comprises an entrance and an exit, and at least one exit and the entrance are not on the same road section in the exit.
In this step, during the running of the vehicle along the current navigation route, the vehicle navigation system may acquire the road conditions of the navigation route in real time, for example, whether the road section is congested, if it is known that the road section ahead is congested, it is determined, according to the electronic map data, whether there is a drivable place such as a parking lot, a gas station, a residence area, etc. on the road section where at least one exit is not located, if there is a drivable place such as a parking lot, a gas station, a residence area, etc. on the road section where at least one exit is not located, it is determined that there is a drivable place on the road section, if there is no drivable place such as a parking lot, a gas station, a residence area, etc. on the road section where at least one exit is not located, etc. on the road section where at least one exit is located, and residence area, etc. if it is determined that there is no drivable place on the road section.
Step 103, it is determined whether or not there is an accessible place with no internal congestion, if there is an accessible place with no internal congestion, step 104 is performed, and if there is no accessible place with no internal congestion, step 102 is performed continuously.
In this step, the parking lot monitoring device, for example, a camera, can monitor whether the interior of the entrance-available place is congested, and provide the detected interior congestion condition of the entrance-available place for the parking lot cloud to store, so that the vehicle-mounted navigation system can determine whether the entrance-available place with no internal congestion condition exists by acquiring the congestion condition of the entrance-available place stored in the parking lot cloud, if the congestion condition of a certain entrance-available place is displayed as non-congested, it can determine that the entrance-available place with no internal congestion condition exists, and if all the congestion conditions of the entrance-available places are displayed as congested, it can determine that the entrance-available place with no internal congestion condition does not exist.
Step 104, obtaining the entrance position of the entrance place without internal congestion, obtaining the exit position of the entrance place which can avoid the front congestion and is close to the destination position, obtaining a plurality of navigation routes of the entrance place for selection according to the entrance position and the exit position, guiding the vehicle to travel to the exit position of the entrance place according to the selected navigation routes, and recalculating and updating the navigation routes based on the exit position of the entrance place and the destination information, and continuing to step 102.
The accessible place without internal congestion not only needs to be free from congestion, but also needs to be close to the destination, for example, closest to the destination, so that driving time can be saved. In the present invention, the judgment of the routes of the parking lot, the gas station, the residential area and the like is added during navigation. When it is determined that traffic jam occurs on the front route, it is determined whether there is a non-public road such as a parking lot, a gas station, a residential area, or the like in front. If it is judged that places such as a parking lot, a gas station and a residential area can be opened to the outside in front, and when the route passing through the place is saved in time or is close to a destination, whether the place is congested is judged, when the place is displayed from the cloud end of the place, the user is prompted to select places meeting the conditions, when the user selects the corresponding place, the vehicle is guided to travel to the exit position of the entrance place according to the selected navigation route, and the navigation route is recalculated and updated based on the exit position of the entrance place and the destination information, so that the user can conveniently avoid the congested road section, the user can be helped to reach the target position more quickly, and the user experience is improved.
In summary, according to the real-time road condition navigation method provided by the embodiment of the invention, the initial navigation route from the current position to the destination of the vehicle is obtained according to the current position information and the destination information of the vehicle by acquiring the current position information and the destination information of the vehicle; acquiring the road condition of the initial navigation route in real time in the process that the vehicle runs along the current initial navigation route, and judging whether a current road section has a drivable place or not if the situation of congestion in the front is known; if the current road section is judged to have the drivable entry site, judging whether the drivable entry site with no congestion exists inside; if the entrance place which is free of the internal congestion exists, the entrance position of the entrance place which is free of the internal congestion is obtained, the exit position which is free of the front congestion and is close to the destination position is obtained, a plurality of navigation routes of the entrance place are obtained according to the entrance position and the exit position for selection, the vehicle is guided to travel to the exit position of the entrance place according to the selected navigation routes, and the navigation routes are recalculated and updated based on the exit position of the entrance place and the destination information, so that a user can be helped to bypass a road section with severe congestion, the user can be helped to reach the destination position more quickly, the user requirement is met, and the user experience is good.
