Intelligent u-turn method and device

Abstract

The invention discloses an intelligent u-turn method and device, and belongs to the field of automobile active safety. The method comprises the steps that in the automobile u-turn process, the current environment state information is obtained in real time and includes lane width, the position of an automobile in a lane, and the included angle of the automobile and a lane boundary; according to a u-turn strategy value table and the current environment state information, the decision action corresponding to the current environment state information is obtained, and a plurality of automobile states, state variables of the states and corresponding decision actions are stored in the u-turn strategy value table; and the automobile is controlled to execute the decision action when one decision action is obtained, and obtaining of the environment state information and the decision actions continues till the automobile reaches the target state. The intelligent u-turn method is obtained through independent study. The method is allocated to an automobile-mounted system of the automobile, u-turn of the automobile in the real environment is achieved, and the intelligent u-turn method and device have stability, self-adaptation, maneuverability 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...
