Vehicle driving system
First Claim
1. A vehicle driving system in which one of front wheels and rear wheels is driven by an internal combustion engine and the other thereof is driven by an electric motor, comprising:
- a generating apparatus that generates electric power by rotation of the internal combustion engine;
said electric motor driven by electric power outputted from the generating apparatus; and
a control unit for controlling output power of the generating apparatus in accordance with a driving force requested from a vehicle and controlling the electric motor, wherein the generating apparatus comprises a tandem generator equipped with a charge function for charging a vehicle-mounted battery and a power supply function for driving the electric motor.
