Disclosed is a method for controlling a damping function of a motor control unit (12) of an electric vehicle, in which the damping function is used for damping rotational vibrations of a transmission system (3) driven by an electric motor (2) by controlling the electric motor (2), the method comprises the following steps: determining, by a vehicle control unit (11), whether the electric vehicle is in a predetermined working condition based on vehicle working condition parameters that cannot be actively acquired by a motor control unit (12); if it is determined that the electric vehicle is in the predetermined operating condition, allowing activation of a damping function of the motor control unit (12) by the vehicle control unit (11); if it is determined that the electric vehicle is not in the predetermined operating condition, the damping function of the motor control unit (12) is turned off. A corresponding vehicle control unit (11) for an electric vehicle and a corresponding computer program product are also disclosed. And the negative influence of the vibration reduction function can be avoided.
公开了一种用于控制电动车辆的电机控制单元(12)的减振功能的方法,其中,所述减振功能用于通过控制电动机(2)来减弱由电动机(2)驱动的传动系统(3)的旋转振动,该方法包括以下步骤:通过车辆控制单元(11)基于电机控制单元(12)无法主动获取的车辆工况参数确定电动车辆是否处于预定工况下;如果确定电动车辆处于预定工况下,允许通过车辆控制单元(11)激活电机控制单元(12)的减振功能;如果确定电动车辆未处于预定工况下,使电机控制单元(12)的减振功能处于关闭状态。还公开了一种相应的用于电动车辆的车辆控制单元(11)以及一种相应的计算机程序产品。能避免减振功能的负面影响。
