The invention relates to the technical field of vehicle body stabilization, and provides a method and system for stabilizing a vehicle body, and the method comprises the steps: collecting the actual vehicle speed v of the vehicle and the actual rotation speed N of the vehicle; according to a preset slip rate s, a tire radius r and a rotation ratio i, calculating an expected rotation speed Nexpectation of the motor, comparing N with the Nexpectation, and adopting a torque mode according to a comparison result; or the motor rotating speed is controlled to stabilize the vehicle body. Whether the current driving state of the vehicle is unstable or not is judged by collecting information such as the vehicle speed and the rotating speed in real time, then the rotating speed of the motor is controlled according to the judgment result, the vehicle body rapidly recovers the stable state, and the safety and stability of the vehicle are improved.
本发明涉及稳定车身技术领域,提供一种稳定车身的方法及系统,包括:采集所述车辆的实际车速v及所述车辆的实际转速N;根据预设的滑移率s、轮胎半径r和转动比i计算出电机的期望转速N期望,将N与N期望作比较,根据比较结果采用扭矩模式;或控制电机转速,稳定车身。本发明通过实时采集车辆车速、转速等信息,判断车辆当前的行驶状态是否失稳,再根据判断结果控制电机转速,使车身快速恢复稳定状态,提高了汽车的安全性和稳定性。
