Embodiment Construction
[0016] During the driving process of the pure electric vehicle, the power output of the drive motor is directly connected to the drive axle through the multi-speed reducer without passing through the clutch, so as to realize clutchless gear shifting. The driver controls the driving speed of the vehicle completely through the accelerator, while the shifting process in the gearbox is completely automatically completed under the relevant control devices of the vehicle.
[0017] During the working process of the electric vehicle, the electric energy of the battery is converted into AC current, and the motor controller will generate corresponding current according to the power required by the vehicle. The torque of the motor is decelerated and increased through the gearbox. According to the needs of the road, the automatic transmission system (AMT) controller generates corresponding control commands to select different gears. The gearbox torque is transmitted to the rear axle final ...
