The invention belongs to the technical field of vehicles, and particularly relates to a vehicle slip protection method and device and a vehicle. The vehicle slip protection method comprises the following steps that the PV value of a differential mechanism is checked, conversion testing is carried out based on the PV value, and a differential mechanism capacity limiting value curve based on a TN value is obtained; acquiring real-time rotating speed difference and real-time output torque of left and right wheels of the speed reducer; using the real-time rotating speed difference and the real-time output torque to judge the use condition of the differential according to the differential capacity limit value curve, judging whether the output torque upper limit needs to be controlled or not, and entering a protection mode; and when the upper limit of the output torque needs to be controlled and a protection mode is entered, whether man-machine prompting is carried out or not is judged according to the vehicle state. According to the vehicle slip protection method and device and the vehicle, the use safety of vehicle hardware can be protected, the problem that accidents are caused by abuse due to the fact that a user does not know the limit capacity of the vehicle is avoided, and the safety of the vehicle and the user is ensured.

    本发明属于车辆技术领域,具体涉及一种车辆打滑保护方法及其装置、车辆。本发明的一种车辆打滑保护方法,包括以下步骤:对差速器的PV值进行检核,基于PV值进行换算测试,得到基于TN值的差速器能力限值曲线;获取减速器左右轮实时转速差和实时输出扭矩;以实时转速差和实时输出扭矩根据差速器能力限值曲线对差数器使用工况进行判断,判断是否需要控制输出扭矩上限,进入保护模式;当需要进行控制输出扭矩上限,进入保护模式时,根据车辆状态判定是否进行人机提示。本发明的一种车辆打滑保护方法及其装置、车辆,能够保护车辆硬件使用安全,避免出现因用户不清楚车辆极限能力,滥用所引发事故的问题,确保车辆和用户安全。
