    • A driving force distribution device which controls the engagement forces of electromagnetic clutches and which govern the torque distribution between the driving wheels of a vehicle by calculating a target magnetic flux density and converting the same into a target excitation current. Since the relationship between the target magnetic flux density and the target excitation current changes according to a decrease in the air gaps accompanying wear of the frictional engagement members of the electromagnetic clutches, a relationship between the magnetic flux density and the excitation current is determined by applying current to the electromagnetic clutches when torque distribution control is not being carried out such as when the system is started, and the target excitation current is calculated from the target magnetic flux density based on the determined relationship. Since there is no need to detect dynamic changes in the magnetic flux density, inexpensive devices can be used as magnetic flux density detecting means so contributing to a reduction in the cost.

    • A vehicle co-operative control system is provided which suppresses the torque steer phenomenon by co-operatively controlling a driving force and/or braking force distribution device and an electric power steering device without changing the control device of the electric power steering device for a vehicle having a specification in which the co-operative control is not carried out or with the introduction of only a minimal change. The control device can also be applied to a vehicle having a specification in which the co-operative control is carried out. In order to achieve this, the steering torque detected by the steering torque detecting device is input into a corrected steering torque calculating device of a first electronic control unit for controlling the driving force and/or braking force distribution device and a corrected steering torque which has been calculated in the corrected steering torque calculating device is input into the second electronic control unit for controlling the electric power steering device. The second electronic control unit controls the electric power steering device based on the corrected steering torque and thus the torque steer phenomenon caused by the driving force and/or braking force distribution device is suppressed.
