The invention belongs to the technical field of vehicle rear wheel steering control, and particularly relates to a control method for rear wheel steering during low-speed running of a vehicle. The method is suitable for controlling rear wheel steering when the vehicle speed is smaller than or equal to 30 Km/h, a panoramic look-around system is linked with a rear wheel steering system, control overvehicle rear wheel steering is stopped under the specific low-speed forward steering working condition, the motion trail of the rear portion of a vehicle body is kept within the motion trail of the front portion of the vehicle body, and therefore collision accidents are avoided. And under the specific low-speed reverse gear steering driving working condition, the rear wheel rotating angle is controlled to be the extreme angle in a certain direction, and reversing and parking are facilitated.
本发明属于车辆后轮转向控制技术领域,具体涉及一种车辆低速行驶时后轮转向的控制方法;适用于车速≤30Km/h时对后轮转向的控制,将全景环视系统与后轮转向系统联动,在特定的低速前进转向工况下,将停止对车辆后轮转向的控制,保持车身后部运动轨迹在车身前部运动轨迹之内,从而避免磕碰事故的发生;在特定的低速倒档转向行驶工况下,控制后轮转角为某个方向的极限角度,方便倒车入库。
