1. An apparatus for controlling turning behavior of a multi-wheeled automotive vehicle supported on a plurality of pairs of wheels, the apparatus comprising:

  • braking means for applying braking forces to the respective wheels;

    first sensor means sensitive to a vehicle steering condition for producing a first signal indicative of a sensed vehicle steering condition;

    second sensor means sensitive to a vehicle lateral slip angle for producing a second signal indicative of a sensed vehicle lateral slip angle; and

    a control unit coupled to the first and second sensor means, the control unit including means for providing a difference between the braking forces applied to nearside and offside wheels of at least one of the pairs of wheels based upon the sensed vehicle steering condition to produce a yaw moment in a direction to which the vehicle turns, and means for modifying the difference based upon the sensed vehicle lateral slip angle to decrease the difference as the vehicle lateral slip angle increases.
