The invention provides a hybrid power system and a control method thereof. The hybrid power system comprises an engine, a first motor, a clutch and a stepless speed change device; an output shaft of the first motor is a hollow shaft; the clutch is coaxially inserted in the hollow shaft and comprises a flywheel, a driven disc and a connecting shaft, the flywheel is movably sleeved outside the connecting shaft in the circumferential direction, the outer circumferential wall of the flywheel is connected with the inner wall of the hollow shaft, the driven disc is movably sleeved outside the connecting shaft in the axial direction and is fixed with the connecting shaft in the circumferential direction, and the outer circumferential wall of the driven disc is separated from the inner wall of the hollow shaft; the driven disc is configured to controllably move in the axial direction of the connecting shaft so as to be connected with or separated from the flywheel in an attached mode, and the connecting shaft is in transmission connection with an output shaft of the engine; and the stepless speed change device comprises a first rotating shaft and a second rotating shaft which are in transmission connection, the first rotating shaft is in transmission connection with the hollow shaft, and the second rotating shaft is in transmission connection with wheels. The axial size of the hybrid power system can be reduced, and the automobile internal space occupied by the hybrid power system is reduced.

    本公开提供了一种混合动力系统和控制方法,包括:发动机、第一电机、离合器和无级变速装置;第一电机的输出轴为空心轴;离合器同轴插装在空心轴内,离合器包括飞轮、从动盘和连接轴,飞轮周向活动地套装在连接轴外,且飞轮的外周壁与空心轴的内壁相连,从动盘轴向活动地套装在连接轴外且与连接轴周向固定,从动盘的外周壁与空心轴的内壁分离,从动盘被配置为可操控地沿连接轴轴向移动,以与飞轮贴合相连或分离,连接轴与发动机的输出轴传动连接;无级变速装置包括传动连接的第一转轴和第二转轴,第一转轴与空心轴传动连接,第二转轴与车轮传动连接。本公开能缩减混合动力系统的轴向尺寸,减小混合动力系统占用的汽车内部空间。
