Embodiment Construction
[0031] The vibration suppression method of pure electric vehicles based on the gear-based strategy and active damping of the present invention includes the following steps:
[0032] Step 1. Consider the resistance factor of the vehicle system. When the motor output torque is greater than a certain value, it will have an effect on the driving of the vehicle. The minimum value of the torque is set as the gear torque. When the motor output torque is greater than the gear torque value , the gear components of the transmission system are pressed against each other to drive the vehicle; when the torque is lower than the tooth contact torque, the transmission system is in a state of control but no force, and the sharp change of the torque will increase during the duration of this state The vibration of the whole vehicle, such as rapid acceleration or deceleration;
[0033] Step 2. Shorten the state time of the transmission system under control and no force by correcting the requested...
