Abstract
A clutchless transmission apparatus and control method thereof. The transmission apparatus comprises a motor (10) and a transmission (20), said motor (10) is connected to said transmission (20) and supplies power to said transmission (20) via an input shaft of the transmission (20), wherein said apparatus further comprises a control device (30), which is electrically connected to said motor (10) and said transmission (20), wherein said control device (30) is configured to determine whether a gear-position shifting is required based on rotation speed of said transmission (20), if a gear-position shifting is required, regulates torque of said motor (10) to control said transmission (20) to disengage, and then regulates the rotation speed of said motor (10) based on the rotation speed of said transmission (20) to control said transmission (20) to engage for shifting gear-position. The clutchless transmission apparatus provided in the present invention doesn't need a clutch during gear-position shifting, and therefore it is light, simple, easy to maintain and control, and can be used in a wide range of application.
