Species vehicle hybrid propulsion system

The present invention discloses a kind of hybrid vehicle drive system, comprising: an electronic control unit for driving the vehicle by the control unit to select a clutch and a lock mechanism. Motor drive unit for, when the energy storage device is in the first station is greater than a preset Moreover, the electrical storage start threshold to provide power for the vehicle. A drive unit for the secondary element is in the first working Moreover, when the energy storage device is less than or equal to a preset threshold value electrical storage accumulator is greater than a preset threshold value accumulator providing power for the vehicle to start. Engine driving means for, when the accumulator is in the first threshold energy storage device ENGINEERING Moreover than or equal to a predetermined threshold value stored electricity accumulator is less than or equal to a preset; or when in the second operating condition providing starting power to the vehicle energy. By the present invention, the energy consumption of the vehicle can be reduced without affecting the normal life and production, achieve maximum energy saving effect.
