The invention provides a chassis domain control method under a high-speed working condition and a related device. The method comprises the steps of detecting whether a vehicle is in a limit early warning state or not when the vehicle is in a high-speed working condition; wherein when the speed of the vehicle is larger than the preset speed, it is determined that the vehicle is in the high-speed working condition; the limit early warning state is a slip early warning state or a steering early warning state; if it is detected that the vehicle is in the slip early warning state, the output torque of the motor is controlled to be reduced; and if it is detected that the vehicle is in the steering early warning state, torque vector control is conducted on the vehicle, and the vehicle generates yawing moment. According to the invention, safety control can be carried out before an emergency occurs in the vehicle, and the driving safety is improved.

    本申请提供一种高速工况的底盘域控制方法及相关装置。该方法包括:在车辆处于高速工况时,检测车辆是否处于极限预警状态;其中,在车辆的车速大于预设车速时,确定车辆处于高速工况;极限预警状态为打滑预警状态或转向预警状态;若检测到车辆处于打滑预警状态,则控制电机的输出扭矩降低;若检测到车辆处于转向预警状态,则对车辆进行扭矩矢量控制,使车辆产生横摆力矩。本申请能够在车辆出现突发情况之前进行安全控制,提高驾驶安全性。
