Abstract

The invention relates to a hybrid power transmission system and a control method thereof for a hybrid car. The hybrid power transmission system mainly comprises an engine, a first electric motor, a second electric motor, a planetary gear, a main shaft, a first clutch and a third clutch. Different operational modes of the hybrid power transmission system can be realized through controlling the engine, the first and the second electric motors to stop or work, and controlling the connection or disconnection of the first clutch, a second clutch or a brake and the third clutch.

Description

【Technical field】 [0001] The present invention relates to a hybrid electric vehicle, and in particular, the present invention relates to a hybrid power transmission system for a hybrid electric vehicle. 【Background technique】 [0002] At present, vehicles are more and more commonly integrated into the lives of ordinary families. However, vehicles that traditionally use gasoline or diesel internal combustion engines as power systems need to consume a lot of petroleum energy, and the exhaust gas emitted by the engines has had a serious impact on the earth's environment on which we live. These deficiencies have become more apparent in recent years due to the increasing shortage of petroleum energy sources and the increasing popularity of domestic vehicles. Just like this, energy saving and environmental protection have become an important direction for the development of the automobile industry. The world's major vehicle manufacturers are concentrating on the research and dev...
