  • Patent number: 7643922
    Abstract: A turning behavior control device for vehicle has a left and right wheel driving force adjustment mechanism for adjusting a difference in driving force between right and left, a braking force adjustment mechanism for adjusting a difference in braking force between the wheels, an auxiliary steering mechanism for adjusting a steering angle of the wheels, a vehicle velocity sensor, a steering wheel sensor, and a yaw rate sensor for detecting the behavior of a vehicle, and a control unit for controlling the foregoing mechanisms based on the vehicle velocity, the steering angle, and the yaw rate detected by the sensors. The control unit operates the front wheel auxiliary steering mechanism before operating at least one of the left and right wheel driving force adjustment mechanism and the braking force adjustment mechanism.

  • Patent number: 7263424
    Abstract: An apparatus for controlling driving forces supplied to left and right wheels of a vehicle, for effectively inhibiting oversteer and understeer states, includes driving force adjusting device for adjusting driving forces supplied to the left and the right rear wheels, first controlling device for controlling the driving force adjusting device such that a wheel speed difference between the left and the right rear wheels coincides with a target wheel speed difference, and second controlling device for controlling the driving force adjusting device such that a yaw momentum of the vehicle coincides with a target yaw momentum. If the vehicle is in an understeer state, the contribution of the second controlling device is increased relative to that the first controlling device and if the vehicle is in an oversteer state, the contribution of the first controlling device is increased relative to that of the second controlling device.
