  • 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.
