The embodiment of the invention relates to the technical field of vehicle control, and discloses a vehicle anti-lock control method which comprises the following steps: acquiring driving state information and wheel speed information of a target vehicle; reference wheel speed information of each wheel is calculated according to the wheel rolling radius and the wheel angular velocity, and the initial slip rate of each wheel is determined based on the reference wheel speed information and a wheel speed-slip rate mapping table; calculating a wheel acceleration value according to the wheel speed information; if the initial slip rate is smaller than a first preset value, obtaining a first control instruction; and a hydraulic braking control signal and/or a motor braking control signal are/is generated according to the first control instruction to achieve vehicle braking. According to the vehicle anti-lock control method in the embodiment of the invention, the actual slip rate of each wheel is accurately calculated to be provided for the vehicle as a data basis for vehicle brake control, so that the final driving safety is improved.
本发明实施例涉及车辆控制技术领域,公开了一种车辆防抱死控制方法,包括:获取目标车辆的行驶状态信息和轮速信息;根据车轮滚动半径和车轮角速度计算得到各个车轮的参考轮速信息,并基于参考轮速信息与轮速‑滑移率映射表来确定各个车轮的初始滑移率;根据轮速信息计算得到车轮加速度值;若初始滑移率小于第一预设值,则获取第一控制指令;根据第一控制指令生成液压制动控制信号和/或电机制动控制信号以实现车辆制动。本发明实施例中的车辆防抱死控制方法通过对各个车轮的实际滑移率来进行精准计算来提供给车辆作为车辆制动控制的数据基础,进而提升最终行车的安全性。
