The embodiment of the invention provides an anti-lock control method and system of a vehicle and an electric vehicle, and belongs to the technical field of vehicle automatic control. The method specifically comprises the steps of collecting state information of a vehicle; determining the current slip rate of the electric driving wheel of the vehicle according to the state information and a slip rate model; under the condition that the current slip rate is larger than or equal to a preset slip rate threshold value, determining the target wheel speed of the motor driving wheel according to the state information and a slip rate model; and regulating the wheel speed of the motor driving wheel to the target wheel speed, so that the slip rate of the motor driving wheel is reduced to be smaller than a preset slip rate threshold value. According to the scheme, the wheel speed of the motor driving wheel is adjusted to the target wheel speed, the slip rate of the motor driving wheel can be reduced to be smaller than the preset slip rate threshold value; therefore, it is ensured that the slip rate in the braking process is within the safety range, and the braking anti-lock safety is provided.

    本申请实施例中提供了一种车辆的防抱死控制方法、系统及电动车,属于车辆自动控制技术领域,该方法具体包括:采集车辆的状态信息;根据状态信息及滑移率模型确定车辆的电动驱动轮的当前滑移率;在当前滑移率大于或者等于预设滑移率阈值的情况下,根据状态信息及滑移率模型确定电机驱动轮的目标轮速;将电机驱动轮的轮速调整至目标轮速,以将电机驱动轮的滑移率降低至小于预设滑移率阈值。通过本公开的方案,通过将电机驱动轮的轮速调整至目标轮速,可以实现将电机驱动轮的滑移率降低至小于预设滑移率阈值,确保制动过程中的滑移率处于安全范围,提供制动防抱死的安全性。
