The invention discloses a vehicle anti-lock braking system, a control method of the vehicle anti-lock braking system and a vehicle. The control method comprises the steps that the slip rate of each wheel is obtained; detecting that an electronic stability control system of the vehicle is activated or determining that a vehicle steering angle is greater than or equal to a preset steering threshold; the maximum slip rate in the slip rates of the wheels on the same side in the first front axle and the second front axle or the first rear axle and the second rear axle is obtained; if the maximum slip rate in the slip rates of the wheels on the same side in the first front axle and the second front axle and/or the maximum slip rate in the slip rates of the wheels on the same side in the first rear axle and the second rear axle reaches an anti-lock threshold value, the wheels with the maximum slip rates reaching the anti-lock threshold value are used as target wheels; and according to the slip rate of the target wheel, controlling the target wheel and an anti-lock actuator of a brake channel corresponding to a wheel on the same side of the target wheel. By means of the method, anti-lock adjustment can be directly conducted on the wheels, the locking phenomenon caused by indirect control over the wheels of the front axle and the rear axle is avoided, the adjustment stability of the electronic stability control system is ensured, and the risk that the vehicle turns over on one side is reduced.
本发明公开了一种车辆防抱死制动系统及其控制方法和车辆,所述控制方法包括:获取每个车轮的滑移率;检测到车辆的电子稳定控制系统激活或者确定车辆转向角大于或等于预设转向阈值;获得前一桥和前二桥或后一桥和后二桥中同侧车轮的滑移率中的最大滑移率;若前一桥和前二桥中同侧车轮的滑移率中的最大滑移率和/或后一桥和后二桥中同侧车轮的滑移率中的最大滑移率达到防抱死阈值,则以最大滑移率达到防抱死阈值的车轮为目标车轮,根据目标车轮的滑移率控制目标车轮以及目标车轮的同侧车轮对应的制动通道的防抱死执行器。采用该方法可以直接对车轮进行防抱死调节,避免间接控制前桥和后桥车轮而发生抱死现象,确保了电子稳定控制系统调节的稳定性,减少了车辆发生侧翻的风险。
