Abstract

The invention provides an electromechanical automatic transmission (EMAT) device, an automobile and a speed-change control method thereof, belonging to the technical field of automobile transmission. The EMAT device comprises a transmission mechanism, a motor and a speed-change control unit, wherein the transmission mechanism comprises a chute, a speed change mechanism, an input shaft and an output shaft; the chute is connected with an external engine; the power of the engine is operably output through the chute, the input shaft, the speed change mechanism and the output shaft in order; the rotor of the motor is connected to the output shaft; and the speed-change control unit is used for controlling the motor to output a torque to the output shaft when the chute is disengaged during a gearshift process. The automobile is a hybrid electric vehicle utilizing the EMAT device. The EMAT device and the automobile have the advantages of good gearshift smoothness, high transmission efficiency and low cost.

Description

technical field [0001] The present invention relates to a transmission device of an automobile, in particular to an electromechanical automatic transmission (Electromotion Automated Mechanical Transmission, EAMT) device, a hybrid vehicle using the automatic transmission device, and an automatic transmission control method for the vehicle. Background technique [0002] Speed ​​change devices are widely used in equipment for speed and traction transmission of machines such as automobiles. The transmission device of a vehicle (such as a car) changes the torque of the power output device (such as an internal combustion engine or an electric motor) by changing the transmission ratio to adapt to the driving wheel traction force and The needs of different requirements for vehicle speed, as well as the realization of reverse driving, interruption of power transmission, and realization of neutral gear, etc. Common speed change devices include various modes such as gear transmission,...
