The invention discloses a vehicle stability control method based on rear wheel steering, belongs to the technical field of automobile suspension control, and aims to solve the problems that in actualrear wheel steering development, the posture change of a vehicle is not considered, so that the actual use requirement of the set distance of the rear wheel steering angle is deviated, and the actualcontrol of the vehicle is not fine enough. On the basis of an original rear wheel turning angle calculation module, a rear wheel angle correction module is added, a vehicle signal is received, a rearwheel turning angle change value caused by a suspension system in a vehicle state and a corresponding state is estimated, and a rear wheel correction turning angle value for offsetting the turning angle is given, so that the controllability control of the whole vehicle is more accurate, And the driving stability of the vehicle under the turning braking/accelerating working condition is improved.

    本发明公开了一种基于后轮转向的车辆稳定控制方法,属于汽车悬架控制技术领域,本发明为了解决在实际的后轮转向开发中,未考虑车辆的姿态变化,导致后轮转角的设定距离实际的使用需求有偏差,对于车辆的实际控制不够精细。通过在原有的后轮转角计算模块的基础上,增加了一个后轮角度修正模块,通过接收车辆信号,估算车辆状态及相应状态下由于悬架系统引起的后轮转角变化值,并给出抵消该转角的后轮修正转角值,对整车的操控性控制的更精准,提升车辆在转弯制动/加速工况下的行驶稳定性。
