Abstract
(EN) A vehicle steering control method, device and system. The control method comprises: acquiring a vehicle speed signal and a steering angle signal of a steering wheel of a vehicle; determining, according to the vehicle speed signal, a proportional coefficient of a front wheel steering angle and a rear wheel steering angle of the vehicle; determining the front wheel steering angle according to the steering angle signal of the steering wheel; and calculating the rear wheel steering angle according to the proportional coefficient and the front wheel steering angle, so as to improve the safety and reliability of vehicle steering control.
(FR) L'invention concerne un procédé, un dispositif et un système de commande de direction de véhicule. Le procédé de commande selon l'invention consiste : à acquérir un signal de vitesse de véhicule et un signal d'angle de direction d'un volant de véhicule ; à déterminer, en fonction du signal de vitesse de véhicule, un coefficient proportionnel d'un angle de direction de roue avant et d'un angle de direction de roue arrière du véhicule ; à déterminer l'angle de direction de roue avant en fonction du signal d'angle de direction du volant de direction ; et à calculer l'angle de direction de roue arrière en fonction du coefficient proportionnel et de l'angle de direction de roue avant, de sorte à améliorer la sûreté et la fiabilité de la commande de direction de véhicule.
(ZH) 一种车辆转向控制方法、装置及系统,控制方法包括:获取车辆的车速信号和方向盘的转角信号;根据所述车速信号,确定所述车辆的前轮转角与后轮转角的比例系数;根据所述方向盘的转角信号确定所述前轮转角;根据所述比例系数和所述前轮转角,计算所述后轮转角,以提高车辆转向控制的安全性和可靠性。
