The invention provides a dynamic stability control method and device for a vehicle, and the method comprises the following steps: an obtaining step: obtaining the actual yaw velocity, the steering wheel angle and the torque of an engine or a motor of the vehicle; and an engine or motor torque control step for determining whether or not there is an understeering on the basis of the actual yaw rate and the steering wheel angle, and if there is an understeering, performing torque reduction control on the torque of the engine or motor of the vehicle on the basis of the actual yaw rate and the steering wheel angle. As a result, responsiveness of the vehicle to the steering operation can be improved.

    本发明提供一种车辆动态稳定控制方法及装置,包括如下步骤:获取步骤,获取所述车辆的实际横摆角速度、方向盘转角、发动机或电机的扭矩;以及发动机或电机扭矩控制步骤,基于实际横摆角速度及方向盘转角判定是否存在转向不足,当存在转向不足时,基于实际横摆角速度及方向盘转角对车辆的发动机或电机的扭矩进行降低扭矩的控制。由此,能提高车辆对于转向操作的响应性。
