1. A control system for an automotive vehicle having a vehicle body comprising:

  • a yaw rate sensor generating a yaw rate signal corresponding to a yawing angular motion of the vehicle body;

    a lateral acceleration sensor generating a lateral acceleration signal corresponding to a lateral acceleration of a center of gravity of the vehicle body;

    a steering angle sensor generating a steering angle signal corresponding to a hand wheel angle;

    a plurality of wheel speed sensors generating wheel speed signals corresponding to each four wheel speed of the vehicle; and

    a yaw stability control unit and a roll stability control unit coupled to said yaw rate sensor, said lateral acceleration sensor, said steering wheel angle sensor and said plurality of wheel speed sensors, said yaw control unit and said roll stability control unit determining a respective yaw stability control signal and a roll stability control signal from the yaw angular rate signal, the lateral acceleration signal, the steering wheel angle signal, and the wheel speed signals; and

    an integration unit coupled to the yaw stability control unit and the roll stability control unit, said integration unit determining a safety system control signal in response to the yaw stability control signal and the roll stability control signal.
