AI Technical Summary

Technical Problem

When facing a complex parking environment, the automatic parking system cannot accurately identify obstacles such as small steps, uneven road surfaces, low obstacles and high speed bumps, resulting in insufficient torque of the power system and unable to successfully overcome these obstacles, which in turn leads to the vehicle's attempt to park automatically many times but fails to succeed.

Method used

During the automatic parking process, whether the vehicle has fallen back occurs based on the actual vehicle speed, actual motor speed and parking distance, and count the number of fallen backs; determine whether the vehicle has stopped stagnant based on the motor driving torque, and count the number of stagnant times; determine whether the comprehensive counting results determine whether there is an obstacle.

Benefits of technology

It realizes accurate identification of obstacle scenarios during automatic parking, improves the robustness of automatic parking for scene recognition, and improves the reliability and safety of automatic parking functions.

Abstract

The invention discloses a method, a device and equipment for identifying an obstacle scene in an automatic parking process, and the method comprises the steps: in the automatic parking process, determining whether vehicle rollback occurs in the automatic parking process according to the actual speed of a vehicle, the actual rotating speed of a motor and a parking distance, and counting the number of times of vehicle rollback; according to the motor driving torque, whether vehicle stagnation occurs in the automatic parking process or not is determined, and the number of vehicle stagnation times is counted; according to the method, whether the obstacle is encountered in the automatic parking process or not is judged according to the counting result, it is achieved that whether the obstacle is encountered in the automatic parking process or not is comprehensively judged through multiple parameters, the obstacle scene can be accurately recognized, the scene recognition robustness of automatic parking is improved, and the reliability and safety of the automatic parking function are improved.
