Collision avoidance processing method of automatic parking system for static obstacles

Abstract

The invention discloses a collision avoidance processing method for an automatic parking system aiming at a static obstacle, which comprises the following steps of: 1) starting a full-automatic parking system, and scanning and searching an idle parking space through an ultrasonic radar or an ultrasonic radar and a high-definition camera; 2) determining a certain idle parking space as a target parking space to be parked; and (3) in the automatic parking process, an electric power steering system is controlled to steer, an electronic gear shifting system is controlled to execute gear shifting, and a vehicle body stabilizing system and an engine management system are controlled to achieve advancing, retreating or stopping of the vehicle, so that the full-automatic parking function is achieved, static obstacles are avoided, and finally the vehicle is parked in a target parking space. Recognition and judgment of the static obstacle are achieved, and the method is applied to an automatic parking system; the problems of safety risks, scene adaptability and the like when static obstacles are located at different positions in the parking environment of a current automatic parking system are solved. The static obstacle recognition processing method is higher in precision, wider in range and higher in confidence coefficient.

Description

technical field [0001] The invention relates to the field of automatic parking, in particular to a collision avoidance processing method of an automatic parking system for stationary obstacles. Background technique [0002] In view of the fact that the automatic parking function has been widely used in the automotive field, it has been well known by the majority of car users. Many domestic and foreign manufacturers and emerging car manufacturers have developed and mass-produced cars equipped with automatic parking functions; automatic parking. The vehicle system is a system that can realize the functions of automatic parking and storage of vehicles by controlling the steering, braking, gear and other actuators. Car pressure, improve user experience. For example, CN112099497A (An obstacle avoidance control method, device, vehicle and medium, application number 202010935901.5), which includes: after turning on the vehicle obstacle avoidance function based on the received obst...
