Embodiment Construction
[0047] The technical solutions of the present invention will be described in detail below with reference to the accompanying drawings.
[0048] Scenario Definition:
[0049] Generally speaking, there will be a variety of traffic light rules at the intersection. Only the left turn waiting area is considered here. The left turn in a single direction is not synchronized, and the right turn can pass freely, and there is a vehicle U-turn.
[0050] Rule description:
[0051] First of all, consider the scene where at one end of the intersection, turning left and going straight are all red lights, then straight ahead with the green light on first, the vehicles going straight pass, the vehicles turning left enter the waiting area, and the U-turn vehicle in the front row of the intersection directly chooses to make a U-turn. Then the straight green light goes out, the left turn green light turns on, and another part of the U-turn vehicle chooses to make a direct U-turn in the left turn...

The invention discloses an intelligent driving system for vehicle distribution and formation for solving traffic congestion at intersections, comprising: a vehicle end system and a roadside system; the roadside system is used for adaptively adjusting the traffic flow information at the intersection according to the current and previous traffic light intersections. Next traffic light time; receive the vehicle's own feature information and motion status from the vehicle-end system, calculate the network distribution instruction information of each vehicle in the distribution fleet according to this information and the next traffic light time, and issue the distribution to these vehicles. Networking instruction information; the vehicle-end system includes an intelligent distribution formation automatic driving subsystem set on the unmanned vehicle and an intelligent distribution formation auxiliary driving subsystem installed on the manned vehicle; the intelligent distribution formation automatic driving subsystem It is used to send the vehicle's own characteristic information and motion state to the roadside system, receive and execute the distribution networking command information of the roadside system, and conduct networking to generate the control commands for automatic driving.
Description
technical field [0001] The invention relates to the field of intelligent driving, in particular to an intelligent driving system for vehicle distribution and formation for solving traffic jams at intersections. Background technique [0002] With the development of advanced wireless communication technology and a new generation of Internet technologies, the dynamic real-time information interaction between vehicles and vehicles and roads will be implemented in an all-round way, and active vehicle safety control and road collaborative management will be carried out on the basis of the collection and fusion of full-time dynamic traffic information. , fully realize the effective coordination of people, vehicles and roads, ensure traffic safety, and improve traffic efficiency, thus forming a safe, efficient and environmentally friendly road traffic system is possible. Effective vehicle-vehicle coordination and vehicle-road coordination can greatly improve traffic efficiency, espe...
