Discloses is an integrated control system for a vehicle, which is capable of improving the driving performance of the vehicle by integrally controlling a variable gear ratio (VGR) system and an in wheel system intended to independently drive the wheels. The integrated control system for a vehicle of the present invention includes: an input signal processing unit which removes noise components included in a vehicle speed signal, a steering angle signal, a steering angular velocity signal, and a yaw rate signal which are detected from sensors mounted in the vehicle, and converts the signals into digital signals; a basic torque determining unit which determines a basic torque of right and left wheels of the in wheel system, based on information provided by the input signal processing unit; a torque adjustment state sensing unit which determines driving conditions by analyzing information provided by the input signal processing unit, and determines whether to adjust the torque of the in wheel system considering the operation of the VGR system; a torque adjustment value calculating unit which determines the need for torque redistribution in the driving conditions determined by the torque adjustment state sensing unit, and calculates a torque adjustment value for the in wheel system; and a final torque determining unit which determines a final torque to drive the in wheel system by applying the basic torque for each driving condition provided by the basic torque determining unit and the torque adjustment value for each driving condition determined by the torque adjustment value calculating unit, and controls the torque of the right and left wheels of the in wheel system. |
