Step 102: and determining the position coordinates of the traffic jam position points in the current navigation path according to the road condition request information and a prestored map.
In the embodiment of the invention, after receiving the road condition request information input by a user, the CDS sends the road condition request information to the vehicle-mounted central control system, and the vehicle-mounted central control system responds to the road condition request information and acquires the position coordinates of the traffic jam position point in the current navigation path through the prestored map.
Step 103: sending a first road condition description acquisition request to a cloud platform server, so that the cloud platform server can send a second road condition description acquisition request to a second terminal within a first preset range of the position coordinate according to the first road condition description acquisition request; wherein the first road condition description acquisition request includes the position coordinates.
In the embodiment of the invention, after the vehicle-mounted central control system acquires the position coordinates of a traffic jam position point through a prestored map, a first road condition description acquisition request containing the position coordinates of the traffic jam position point is sent to a vehicle networking system (T-BOX), the T-BOX sends the first road condition description acquisition request to a cloud platform server, and the cloud platform server responds to the first road condition description acquisition request and sends a second road condition description acquisition request to a second terminal located in a first preset range of the position coordinates according to the position coordinates of the traffic jam position point. Optionally, the second terminal may be an on-board central control system on a vehicle near the traffic jam location, or may be an electronic device near the traffic jam location, where the vehicle near the traffic jam location receives the second road condition description acquisition request through the T-BOX and sends the second road condition description acquisition request to the on-board central control system, the on-board central control system pushes the second road condition description acquisition request to a user on the vehicle near the traffic jam location through the central display CDS, and the electronic device near the traffic jam location directly receives the second road condition description acquisition request through the APP on the electronic device.
In the implementation of the invention, under the condition of acquiring the road condition request information input by the user, the cloud platform server sends the second road condition description acquisition request to the second terminal located in the first preset range of the traffic jam position point, so that the real-time road condition information request can be realized between the first terminal and the second terminal, further the interaction of the road condition information is realized, and the requirement of the user for predicting the waiting time according to the road condition information is met.
Optionally, the method further comprises:
and acquiring the road condition information which is sent by the cloud platform server and is acquired according to the second road condition description acquisition request.

In the embodiment of the present invention, if the second terminal that receives the second road condition description acquisition request is the vehicle-mounted central control system on the vehicle, and the vehicle is far from the traffic jam location point, in many cases, due to a traffic accident or other reasons, a situation may occur in which the vehicle that is closer to the traffic jam (accident scene) cannot feed back the road condition information, and therefore, the vehicle that needs to be far from the traffic jam location point, that is, the person on the vehicle on which the second terminal that receives the second road condition description acquisition request gets off gets close to the traffic jam location point to check the road condition information, and then the description is performed. When a vehicle central control system on a vehicle far away from a traffic jam position point receives a message that a cloud platform server sends a second road condition description acquisition request, the vehicle central control system on the vehicle sends road condition description time confirmation information, namely time required for describing road condition information, to a first terminal through the cloud platform server, if a user of the first terminal chooses to accept, the vehicle central control system sends acceptance information to the cloud platform server, the cloud platform server sends the second road condition description acquisition request to the vehicle central control system on the vehicle, and if the user of the first terminal chooses to reject, the vehicle central control system sends rejection information to the cloud platform server, and the cloud platform server stops sending the second road condition description acquisition request to the vehicle central control system on the vehicle. According to the embodiment of the invention, the vehicle positioned at the far position of the traffic jam position can receive the second road condition description acquisition request, and the road condition information is obtained in a walking checking mode, so that the first terminal or the request terminal positioned near the traffic jam source can accurately acquire the road condition information of the accident scene.
Optionally, in the embodiment of the present invention, in a first preset time period, if no second terminal responds to the second road condition description acquisition request and sends the road condition description time confirmation information, the cloud platform server sends a search range expansion request to the first terminal, where the search range expansion request includes a second preset area range obtained by expanding the first preset area range, and sends the expanded second preset area range to the vehicle central control system of the first terminal, where the vehicle central control system of the first terminal determines whether the second preset area range is within a limit range preset by the user, and if the second preset area range is within the limit range, sends confirmation information to the cloud platform server, and the cloud platform server sends the second road condition description acquisition request to all second terminals located within the second preset area range according to the confirmation information, and if a second terminal located far away from the traffic congestion location receives the second road condition description acquisition request, the vehicle-mounted central control system of the second terminal sends road condition description time confirmation information, namely time required for describing the road condition information, to the first terminal through the cloud platform server, if the user of the first terminal selects to accept, the vehicle-mounted central control system sends acceptance information to the cloud platform server, the cloud platform server sends a second road condition description acquisition request to the vehicle-mounted central control system on the vehicle, if the user of the first terminal selects to reject, the vehicle-mounted central control system sends rejection information to the cloud platform server, and the cloud platform server stops sending the second road condition description acquisition request to the vehicle-mounted central control system on the vehicle.
As shown in fig. 3, an embodiment of the present invention further provides a road condition information obtaining method, which is applied to a second terminal, and the method includes:
step 301: and acquiring a second road condition description acquisition request sent by the cloud platform server.
