一种在变速箱输出轴增加驱动电机的bsg混合动力系统

BSG hybrid power system with drive motor additionally arranged on output shaft of gearbox

Abstract

The invention discloses a hybrid power system with a BSG and a drive motor arranged on an output shaft of a gearbox and a control method thereof. The system is formed by sequentially connecting the BSG, an ICE, a clutch, the gearbox, the drive motor and a front drive shaft, wherein the drive motor is connected to the output shaft of the gearbox through a gear and has a fixed speed ratio, and the BSG is arranged at the front end of an engine and is connected to the engine through a belt. The invention further discloses the control method of the hybrid power system with the BSG and the drive motor arranged on the output shaft of the gearbox. According to the hybrid power system with the BSG and the drive motor arranged on the output shaft of the gearbox and the control method thereof, the drive motor directly drives the output shaft of the gearbox to rotate through the gear and drives a vehicle to travel; the motor has low speed and large torque, and the efficiency of the motor is obviously higher than the efficiency of the engine at low speed.
本发明公开了一种BSG及驱动电机在变速箱输出轴的混合动力系统及其控制方法,该系统由BSG电机、ICE、离合器、变速箱、驱动电机和前驱动轴依次连接而成, 驱动电机通过齿轮与变速箱的输出轴连接,为固定速比,所述BSG电机布置在发动机的前端,通过皮带与发动机连接。本发明还公开了一种BSG及驱动电机在变速箱输出轴的混合动力系统的控制方法,在本发明中,驱动电机直接通过齿轮驱动变速箱输出轴转动,驱动车辆行驶。电机具有低速大扭矩的特性,在低速时电机的效率明显高于发动机的效率。
