Power Flow Mechanism

Inputted the informations from each sensors in vehicle
- Input torque (Throttle position sensor)
- Cornering situation (Steering angle sensor)
- Vehicle speed and different wheel speed front & rear (Wheel speed sensor)
- Braking situation (Brake signal and ABS signal)
Distributed the required driving force after 4WD ECU operates.
EMC (Electric Magnetic Clutch) operates the primary clutch.
