Abstract
A driving force control system for a vehicle is provided to control an output torque of a prime mover and a torque split ratio to right and left wheels to improve stability of the vehicle. A controller is calculates target torques delivered to the right wheel and the left wheel based on a required drive torque and data relating to an attitude of the vehicle, and corrects the target torques based on slip ratios of the wheels. The drive motor is control based on a first current value calculated based on a total torque of the corrected target torques to be delivered the wheels, and the differential motor is controlled based on a second current value calculated based on a difference between the corrected target torques to be delivered to the wheels.
