The invention provides a wheel anti-lock control method, device and equipment and a storage medium, and the method comprises the steps: firstly obtaining a motor target torque and a motor rotating speed lower limit value calculated by a vehicle control unit, and then transmitting the motor target torque and the motor rotating speed lower limit value to a motor controller; reading the motor rotating speed of the motor controller, and recording the motor rotating speed as the current motor rotating speed; the current motor rotating speed is compared with a motor rotating speed lower limit value received by a motor controller, and when the current motor rotating speed is larger than the motor rotating speed lower limit value, wheel anti-lock control is conducted on the target vehicle through the motor target torque; otherwise, wheel anti-lock control is conducted on the target vehicle through the motor rotating speed lower limit value received by the motor controller. The method can effectively solve the problems that when large electricity feedback is carried out, a control parameter transmission path in traditional anti-lock control is too long, so that wheel locking is likely to happen, and large calibration work and large errors are caused when estimated parameters are used for controlling the vehicle, and more initiative is brought to a main engine plant to control the longitudinal stability of the vehicle.
本申请提供一种车轮防抱死控制方法、装置、设备及存储介质,首先获取整车控制器计算出的电机目标扭矩和电机转速下限值,然后发送给电机控制器;再读取电机控制器自身的电机转速,记为当前电机转速;再将当前电机转速与电机控制器接收到的电机转速下限值进行比对,并在当前电机转速大于电机转速下限值时,利用电机目标扭矩对目标车辆进行车轮防抱死控制;反之,利用电机控制器接收到的电机转速下限值对目标车辆进行车轮防抱死控制。本申请可有效解决较大电回馈时传统防抱死控制中控制参数传递路径过长导致容易发生车轮抱死,以及使用预估参数对车辆进行控制带来较大标定工作和较大误差的问题,也为主机厂对车辆纵向稳定性控制带来更多主动权。
