Intelligent U-turn method and device

Abstract

The invention discloses an intelligent U-turn method and device, which belong to the field of automobile active safety. The method includes: during the vehicle U-turn process, obtaining current environmental state information in real time, the current environmental state information includes the width of the lane, the position of the vehicle in the lane, and the angle between the vehicle and the boundary of the lane; according to the U-turn strategy value table and the The current environmental state information, to obtain the decision-making action corresponding to the current environmental state information, the U-turn strategy value table stores a plurality of vehicle states, the state quantity of each state and the corresponding decision-making action; each time a decision-making action is obtained, Controlling the vehicle to execute the decision-making action and continuing to obtain environmental state information and decision-making actions until the vehicle reaches the target state. The invention obtains an intelligent U-turn method through self-learning, and configures the method in the on-board system of the vehicle to realize the U-turn of the vehicle in the real environment, and has stability, adaptability, mobility and flexibility.

Description

technical field [0001] The invention relates to the field of automobile active safety, in particular to an intelligent U-turn method and device. Background technique [0002] With the increase of car usage year by year, the accident rate is getting higher and higher, therefore, car safety has attracted more and more attention. In the field of automotive safety, automotive active safety has attracted special attention due to its automation advantages. [0003] Automobile active safety refers to adding methods and devices to improve active safety in automobiles so that automobiles can actively take measures to avoid accidents. For example, passive safety systems of automobiles include anti-lock braking systems, blind spot monitoring systems, lane Deviating from the warning system, etc., the characteristics of the car's active safety system are to prevent accidents. [0004] In particular, during the U-turn process, traffic accidents are prone to occur due to the driver’s blo...
