Problems solved by technology

However, for this kind of device, due to the introduction of the drive motor, some problems have been brought about in the process of vehicle gear shifting. If no synchronous control is carried out, it will affect the life of the synchronizer and the quality of gear shifting, and the driver's operating burden will be changed. Heavy
