Automotive hybrid drive system

The utility model relates to an automotive hybrid drive system, which comprises an engine, a power battery and a transmission. The engine is mechanically connected with an ISG motor, the transmission adopts a 6AT transmission, the 6AT transmission is connected with a front wheel drive shaft, the ISG motor is mechanically connected with the 6AT transmission, a rear wheel is provided with a hub motor, and the hub motor is connected with an ISG motor controller through a hub motor controller. Since the small-displacement engine and the hub motor commonly drive the vehicle, the utility model achieves the drive effect of the large-displacement engine. Moreover, the utility model can realize switching of multiple drive modes. The utility model can also convert surplus energy produced during running into electric energy to be stored in the power battery, thereby realizing the purposes of energy conservation and emission reduction.
