The invention provides a vehicle driving path generation method and system. The vehicle driving path generation method comprises the step of determining a lane level connection topology from a current road to a destination road based on a first group of information in map information from the current road where a vehicle is located to the destination road, wherein the first group of information comprises road-level vehicle driving path information and a traffic relationship between all lanes in each road from the current road to the destination road, and the lane-level connection topology comprises nodes associated with the lanes and edges representing the traffic relationship between the nodes. The method further includes the step of generating a routing table based on the lane-level connection topology, the routing table includes paths from all lanes in the current road to a target lane in the destination road. According to the invention, the lane-level vehicle driving path planning can be realized only by using a traditional map and some lane information with a small data volume, a high-precision map is not needed, and the cost of hardware storage is reduced.
Description
technical field [0001] The present disclosure relates to the planning of vehicle driving paths, and in particular to the lane-level planning of lane-level driving paths. Background technique [0002] Currently, most of the navigation used in vehicles is road-level navigation. The path planning provided by this road-level navigation for vehicle driving is based on roads, that is, the provided vehicle driving path is the connection between roads, for example, from Turn left on road A and enter road B, go straight on road B for 1 kilometer and then turn right from road B to road C, etc. When the vehicle is a predetermined distance (for example, 200 meters) from the left-turn or right-turn intersection, the vehicle will be reminded Make a lane change so that the vehicle subsequently performs a successful left or right turn. However, in some cases, such as traffic rush hours, unexpected accidents ahead, etc., when the vehicle receives the lane change reminder, it will not be abl...
