Control Method and System for Fixed-Point Parking in Autonomous Driving

Abstract

A control method, relating to the technical field of automobile intelligent driving includes: determining a target parking spot, and automatically generating target track points, an estimated braking distance, and an estimated coasting distance; calculating the longitudinal distance between the current position and the target end point according to the target track points and the current control deviation; collecting real-time vehicle driving information, and calculating current vehicle speed, slope, and vehicle braking response time information; updating the longitudinal distance at a fixed frequency according to the longitudinal distance to the target end point and the real-time vehicle speed; on the basis of control state decision logic, performing real-time estimation of the distance to the target parking point to determine the vehicle control state. A system for fixed-point parking in autonomous driving includes a vehicle information collection module, a position estimation module, and a control state decision module.
