The invention discloses a vehicle sliding control method and system based on hybrid braking and a vehicle thereof.The method comprises the steps that whether the vehicle has a sliding working condition or not is detected, the braking mode of the vehicle under the current sliding working condition is judged, and a braking force control strategy is executed for friction braking according to an ABS; in the motor braking mode, motor braking force and friction braking force are alternately executed on the wheels, and the speed of the wheels is controlled to oscillate and descend; and in the hybrid braking mode, whether the current vehicle sliding working condition is controllable or not is detected, and corresponding different braking modes are adopted according to the result whether the sliding working condition is controllable or not. The vehicle sliding working condition is controlled based on hybrid braking, the braking mode of the vehicle under the current sliding working condition is judged, different braking control strategies are adopted according to different braking modes, and the safety and reliability of vehicle braking under the sliding working condition are guaranteed.

    本发明公开了一种基于混合制动的车辆滑行控制方法、系统及其车辆,方法步骤包括:检测车辆是否出现滑行工况,判断当前滑行工况下车辆的制动模式,对于摩擦制动按照ABS执行制动力控制策略;电机制动模式下则对车轮交替执行电机制动力和摩擦制动力,控制车轮速度振荡下行;在混合制动模式检测当前的车辆滑行工况是否可控,并根据滑行工况是否可控的结果,采用对应不同的制动模式。本发明基于混合制动对车辆滑行工况进行控制,判断在当前滑行工况下车辆的制动模式,根据不同的制动模式采用不同的制动控制策略,保障滑行工况下车辆制动的安全性和可靠性。
