The invention relates to a vehicle stability judgment method and system and relates to the field of vehicle stability judgment, and the method comprises the steps that the accelerator pedal opening degree, the front wheel rotation angle, the steering angular speed, the vehicle body roll angle and the roll angle speed of a vehicle are obtained; predicting a tire force of a wheel according to an accelerator pedal opening degree of the vehicle, the front wheel steering angle, the steering angular velocity, the vehicle body roll angle and the roll angle velocity; constructing a stability judgment space according to the stability indexes; and determining the vehicle stability according to the stability judgment space and a set vehicle stability area. According to the method, the judgment precision of the overall stability of the vehicle is improved by considering the longitudinal, yaw and roll stability of the vehicle at the same time.

    本发明涉及一种车辆稳定性判断方法及系统,涉及车辆稳定性判断领域,方法包括:获取车辆的加速踏板开度、前轮转角、转向角速度、车身侧倾角和侧倾角速度;根据所述车辆的加速踏板开度、所述前轮转角、所述转向角速度、所述车身侧倾角和所述侧倾角速度预测车轮的轮胎力;根据稳定性指标构建稳定性判定空间;根据所述稳定性判定空间和设定车辆稳定区域确定车辆稳定性。本发明通过同时考虑车辆纵向、横摆和侧倾的稳定性以提高车辆整体稳定的判断精度。
