Embodiment 1

[0039] This embodiment discloses a real-time navigation method based on RSU vehicle import perception, such as figure 1 shown, including the following steps:

[0040] S10. When the vehicle is ready to merge into other roads, the vehicle OBU sends a merge request to the RSU.

[0041] In this step, the initiation condition for the vehicle to merge into the request is: the vehicle OBU collects the turn signals and the current navigation route planning information to determine whether the vehicle needs to merge into other roads.

[0042] see figure 2 , for example: when our vehicle EV needs to merge into other roads, because it is not clear about the current real-time road conditions of the target road that needs to be merged, there will be hidden dangers in safety and efficiency. At this time, the vehicle OBU gathers the turn signal lights and the current navigation The path planning information calculates the target road that the vehicle EV needs to merge into, and the vehicl...

Embodiment 2

[0058] This embodiment discloses an RSU-based vehicle merge-aware real-time navigation system, and uses the RSU-based vehicle merge-aware real-time navigation method described in Embodiment 1 to realize vehicle merge-aware real-time route navigation.

[0059] The system of this embodiment is as image 3 As shown, it includes: a vehicle OBU, a vehicle navigation system and an RSU, and the vehicle OBU communicates with the vehicle navigation system and the RSU respectively.

[0060] The vehicle OBU is used to send the import request to the RSU, and send the result fed back by the RSU to the vehicle navigation system.

[0061] Specifically include: when the vehicle needs to merge into other roads, because the current real-time road conditions of the target road that needs to be merged are not clear, there will be hidden dangers in safety and efficiency. At this time, the vehicle OBU collects the turn signals and the current navigation path planning information It is calculated t...

Abstract

The invention relates to a RSU-based vehicle importing sensing real-time navigation method and system. The method comprises the steps that when a vehicle is ready to importing to other roads, a vehicle OBU sends an importing request to a RSU; after receiving the importing request, the RSU judges whether the vehicle can be smoothly importedaccording to the actual road condition of the target road, and returns corresponding result information to the OBU according to the judgment result; and the OBU generates new path navigation according to the result information sent by the RSU. According to the invention, through the communication between the OBU and the RSU of the vehicle, the road information of the target road needing to be importedis obtained, and the path navigation is updated in real time, so that the path navigation of the vehicle is more real-time, efficient and safer; and the traffic efficiency and safety of vehicles are improved, the traffic efficiency and safety of the whole road are finally improved, and intelligent, efficient and safe travel is better embodied.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a real-time navigation method and system based on RSU-based vehicle merge perception. Background technique [0002] The current car navigation mainly relies on the data of the satellite navigation system, which has problems in real-time, and the satellite navigation has no global route planning scheme, so in the actual driving process of the vehicle, it will bring low traffic efficiency and traffic safety cannot be guaranteed question. For example: when our vehicles need to merge into other roads, and other roads are currently congested, or other roads have just experienced safety hazards, or vehicles that may be driving on the target road when the vehicle merges Collision risks, etc., because the current real-time road conditions of the target road are not clear, there will be hidden dangers in safety and efficiency. Contents of the invention [0003] In o...
