  • Publication number: 20210265935
    Abstract: An electric motor controlling system used for vibration suppression of an electric vehicle is disclosed. The controlling system includes a PID-controller and a vibration suppression compensator. The PID-controller generates a basic torque command through performing a calculation based on input speed-error signal of the electric vehicle, the vibration suppression compensator generates a compensated torque command through performing a compensation gain procedure on the input speed-error signal. The vibration suppression compensator further receives a motor speed of the electric vehicle, sets its output as the compensated torque command when the motor speed is smaller than a preset active speed level, otherwise sets the output as 0. The controlling system generates an output torque command via adding up the basic torque command and the output of the vibration suppression compensator, and operates electric motor components of the electric vehicle according to the output torque command.

  • Publication number: 20200132132
    Abstract: An electric vehicle transmission method includes the steps of: detecting a gear-shift command; judging if the gear-shift command is in conflict, if it is in conflict, then it returns back to the step of detecting the gear-shift command while if it is not in conflict, then proceeds to the next step; proceeding to a synchronized position, a dispelling fork drives a synchronizer to make the synchronizer move from the original gear position to a synchronized position, and the dispelling fork does not move within a synchronized time; and proceeding to a target position, the dispelling fork drives the synchronizer again to make the synchronizer move to the target gear position.
