The invention relates to the technical field of vehicle control, in particular to a vehicle stability control method and system and an electric vehicle, front wheel speed of the vehicle is monitored in real time through a speed sensor installed on a front wheel, rear wheel speed of the vehicle is monitored in real time through a speed sensor installed on a rear wheel, and the speed difference of the front wheel and the rear wheel is calculated; the slip rate sensors installed on the wheels are used for monitoring the slip rate of the wheels in real time; the driving system of the vehicle is controlled to reduce power output according to the comparison condition of the speed difference of the front and rear wheels and the slip rate with the preset threshold value, stable running of the vehicle is guaranteed, sideslip and emergency braking falling accident risks are prevented, the traction performance and stability of the electric vehicle under the complex road surface condition can be effectively improved, and meanwhile the risk of tire slip is reduced.

    本发明涉及车辆控制技术领域,具体涉及一种车辆稳定性控制方法、系统及电动车,利用安装在前轮的速度传感器实时监测车辆前轮速度,利用安装在后轮的速度传感器实时监测车辆后轮速度,计算前后轮速度差;利用安装在各个车轮上的滑移率传感器实时监测各个车轮的滑移率;根据前后轮速度差和滑移率与预设阈值的比较情况控制车辆的驱动系统降低功率输出,保证车辆平稳行驶,防止侧滑和紧急制动摔车事故风险,可以有效提高电动车在复杂路面条件下的牵引性能和稳定性,同时减少轮胎打滑的风险。
