Embodiment Construction
[0030] When the torque load of the vehicle drive motor acts on the transmission system, it will cause the torsional vibration of the shaft system of the transmission system. For example, during the actual operation of an electric vehicle, when the vehicle starts or the torque has a large step response, the transmission system will generate torsional vibration at a fixed frequency, which is manifested by periodic fluctuations in the shafting speed of the transmission system, far exceeding the wheel speed Therefore, it brings a feeling of front and rear jitter to the whole vehicle, which affects the driving comfort of the whole vehicle and the comfort of passengers.
[0031] In the prior art, for the torsional vibration of the electric vehicle system, the main method adopted is to reduce the loading slope of the motor torque. However, a too low loading slope will reduce the torsional vibration of the vehicle, so it cannot effectively balance the needs of vehicle torque loading s...
