Problems solved by technology

[0002] The current manual transmissions are all equipped with synchronizers. During the shifting process of the vehicle, the synchronizer is used to make the speed of the synchronized gears reach the synchronous speed. Therefore, the smoothness of shifting is affected by the inertia of the synchronous end and the capacity of the synchronizer. Especially for heavy-duty transmissions, the synchronous inertia required is large, and the capacity of the synchronizer is increased unilaterally, which is limited by space and the cost will increase. In addition, some products are difficult to meet the requirements even if the capacity of the synchronizer is increased.

Abstract

The invention relates to a transmission, a speed change method and a vehicle, and belongs to the field of vehicles. Smooth gear shifting can be achieved. The transmission comprises an input shaft andan output shaft. The transmission comprises a motor control unit and a motor. The motor control unit is used for receiving a gear shifting signal and the rotating speed of the output shaft, generatinga drive command based on the gear shifting signal and the rotating speed of the output shaft and sending the drive command to the motor. The motor is used for driving the input shaft based on the drive command, so that the rotating speed of the input shaft is consistent with the rotating speed of the rotating shaft of the output shaft.

Description

technical field [0001] The present disclosure relates to the field of vehicles, in particular, to a transmission, a transmission method and a vehicle. Background technique [0002] The current manual transmissions are all equipped with synchronizers. During the shifting process of the vehicle, the synchronizer is used to make the speed of the synchronized gears reach the synchronous speed. Therefore, the smoothness of shifting is affected by the inertia of the synchronous end and the capacity of the synchronizer. Impact, especially for heavy-duty transmissions, which require a large synchronous inertia, increasing the synchronizer capacity unilaterally will be limited by space and the cost will also increase. In addition, some products are difficult to meet the requirements even if the synchronizer capacity is increased. Contents of the invention [0003] The purpose of the present disclosure is to provide a transmission, a shifting method and a vehicle capable of solving ...
