The invention discloses an anti-lock control method, device and system and a vehicle. The method comprises the steps that when a regenerative braking function of the vehicle is triggered, judgment parameters of a vehicle lock trend are obtained; when the judgment parameter of the vehicle locking trend does not fall into the corresponding preset value interval, it is determined that the vehicle has the locking trend; and when the wheels have the locking tendency, the locking probability of the vehicle is reduced by reducing the dragging torque of the motor, and the larger the difference value between the judgment parameter of the locking tendency and the preset value interval reference value is, the larger the reduction amplitude of the dragging torque of the motor is. By adopting the scheme provided by the invention, the probability of brake locking of the A-type regenerative braking system can be reduced, and the use safety of the vehicle is improved.

    本申请公开了一种防抱死控制方法、装置、系统及车辆,所述方法包括:在车辆的再生制动功能被触发时,获取车辆抱死趋势的判断参数;当车辆抱死趋势的判断参数未落入对应的预设取值区间时,确定车辆存在抱死趋势;当车轮存在抱死趋势时,通过降低电机的拖滞力矩以降低车辆的抱死概率,其中,抱死趋势的判断参数与预设取值区间参考值的差值越大,电机拖滞力矩降低的幅度越大。采用本申请所提供的方案,可以降低A型再生制动系统出现制动抱死的概率,提高车辆使用的安全性。
