A system and method for dispatching vehicles with autonomous driving capabilities at intersections

Abstract

The present application proposes a method, device, server and readable storage medium for dispatching vehicles with an automatic driving function at an intersection, wherein the method includes: the server receives a crossing request sent from an automatic driving vehicle in the current period. The intersection request includes the state of the autonomous vehicle in the current period, including information such as position, speed, and planned driving route. Vehicles that entered and did not leave the intersection dispatching area before the current time period are called previous vehicles. The server further obtains the planned driving trajectory of the previous vehicle and generates a speed planning instruction in combination with the crossing request issued by the self-driving vehicle. The server sends the speed planning instruction to the self-driving vehicle. Under the unified dispatch of the server, the vehicles in the intersection dispatching area can increase traffic efficiency while ensuring safety.

Description

technical field [0001] The present application relates to the technical field of automatic driving, in particular, to a system and method for dispatching automatic driving vehicles at intersections. Background technique [0002] With the development of intelligent vehicles and intelligent traffic lights at intersections, how to make intersections more efficient has become a hot spot in the field of urban traffic research, among which intelligent dispatching at intersections is an important part. In the prior art, some cities set up intelligent traffic lights at intersections. The intelligent traffic lights will be calculated according to the traffic flow of each lane waiting at the current intersection, and the duration of traffic lights will be allocated to reduce congestion to a certain extent. However, this method also has certain limitations. Disadvantages: Vehicles in the direction of red lights may still need to stop and wait, and the efficiency of vehicles passing thr...

AI Technical Summary

Problems solved by technology

In the prior art, some cities set up intelligent traffic lights at intersections. The intelligent traffic lights will allocate the duration of traffic lights according to the traffic flow in each lane at the current intersection after calculation, which can reduce congestion to a certain extent, but this method also has certain limitations. Disadvantages: Vehicles in the direction of red lights may still need to stop and wait, and the efficiency of vehicles passing through the intersection is low; parking and restarting of vehicles will also cause a certain amount of fuel waste, and the level of intelligence and automation is low
