A series/parallel hybrid electric drive unit for vehicle comprises an engine (), a main traction motor (), an integrated starter-generator (), a differential (), a first shaft (main shaft) (), a first stage decelerating device (), a second stage decelerating device (), a first clutch (), a second clutch () and a synchronizer (). The synchronizer () is slidably arranged on the first shaft () which is connected to the first stage decelerating device () or the second stage decelerating device () by the synchronizer (), respectively. The hybrid electric drive unit of the invention has a compactly-arranged internal structure and an efficient and appropriate internal connection, and a switch between connection and disconnection of respective hybrid power sources and wheels and a shifting among operating modes and gear positions of the hybrid drive system can be realized.

Hybrid electric drive unit, hybrid drive system and control method thereof

A series/parallel dual motor dual-clutch hybrid electrical driving unit for vehicle includes: a main traction motor (), an integrated starter-generator (), a differential (), a main shaft (), a first stage decelerating device (), a primary clutch () and a first clutch (). Said traction motor () is connected with said first stage decelerating device () via said first clutch (). A series/parallel dual motor triple clutch hybrid electrical driving unit for vehicle further includes a second clutch () and a second stage decelerating device () based on the above described series/parallel dual motor dual-clutch hybrid electrical driving unit. The hybrid electrical driving unit according to the invention is compact in structure arrangement, high efficient and rational in connection. The arrangement based on this invention can be utilized to connect or disconnect each individual hybrid source and wheel, and by altering the power-output torques, the shift of operation modes and gear positions of the hybrid driving system can be further realized.
