System and method for controlling a lateral control system of a motor vehicle based on a model of a wheel steering system

摘要

Method (30) for controlling a lateral control system of a motor vehicle comprising a wheel steering system configured to control the steered wheels of the vehicle, in which: a lateral positioning error of the vehicle is calculated in particular as a function of a desired lateral acceleration of the vehicle and a speed of the vehicle; - the vehicle dynamics are modeled as a function of the vehicle speed and a steering wheel angle value; - a maximum steering wheel angle value is calculated as a function of the calculated lateral positioning error, - the steering system according to a steering wheel angle relationship given by the manufacturer between a maximum steering wheel angle and the vehicle speed, the maximum value of the maximum steering wheel angle is compared with the steering wheel angle relationship from the manufacturer and the smaller of the two steering wheel angle values are transmitted to the vehicle dynamics model.
