Transmission Assembly for Electric Vehicle
First Claim
1. A transmission assembly for an electric vehicle comprising:
- a transmission including an input shaft, an output shaft, and a gear train coupled between the input shaft and the output shaft;
a motor including an output coupled to the input shaft of the transmission;
a motor controller electrically connected to the motor, with the motor controller controlling a rotating speed of the motor; and
a gear controller electrically connected to the motor controller, with the gear controller outputting a speed request signal to the motor controller, and with the motor controller controlling the rotating speed of the motor based on the speed request signal to synchronize rotating speeds of the input shaft and the output shaft of the transmission.

Abstract
A transmission assembly for an electric vehicle includes a transmission having an input shaft, an output shaft, and a gear train coupled between the input shaft and the output shaft. A motor includes an output coupled to the input shaft of the transmission. A motor controller is electrically connected to the motor and controls a rotating speed of the motor. A gear controller is electrically connected to the motor controller. The gear controller outputs a speed request signal to the motor controller, and the motor controller controls the rotating speed of the motor based on the speed request signal, allowing smooth engagement between the gear train and the output shaft.
