The invention provides a vehicle anti-skid control method and system, a vehicle and a storage medium, and belongs to the technical field of vehicle anti-skid control. The method comprises the steps that state information of the vehicle in the driving process and working signals of active safety control are obtained in real time; wherein the state information at least comprises the wheel speed and the vehicle speed; based on the state information, performing slip prediction on the vehicle, the slip prediction being used for determining whether the vehicle is about to slip; determining whether torque control needs to be performed on the vehicle based on a prediction result of the slip prediction and the working signal; if yes, the current wheel slip rate of the vehicle is determined based on the current vehicle speed and the current wheel speed of the vehicle, and a motor of the vehicle is controlled to output the target torque in real time based on the current wheel slip rate and the current vehicle speed till the vehicle exits the slip state. According to the anti-skid control method for the vehicle, the problem of controller over-current caused by overlarge torque change of the motor can be avoided, and the operation stability of the vehicle is improved.
本发明提供了一种车辆防滑控制的方法、系统、车辆及存储介质,属于车辆防滑控制技术领域,该方法包括:实时获取车辆在行驶过程中的状态信息,以及主动安全控制的工作信号;其中,状态信息至少包括车轮轮速与车速;基于状态信息,对车辆进行打滑预测,打滑预测用于确定车辆是否即将打滑;基于打滑预测的预测结果,以及工作信号,确定是否需要对车辆执行扭矩控制;若是,则基于车辆的当前车速与当前车轮轮速,确定车辆的当前车轮滑移率,并基于当前车轮滑移率、当前车速,实时控制车辆的电机输出目标扭矩,直至车辆退出打滑状态。通过本发明所提供的车辆防滑控制的方法,可以避免电机扭矩变化过大引起控制器过流问题,以及提高车辆的操纵稳定性。
