Should vehicle enter comer too fast to negotiate the bend, then providing the inertial forces involved do not exceed in the adhesion limits of the tires, ASC operates to provide optimal control of braking slowing the vehicle and enabling it to negotiate the comer safety.
Should the driver make a sudden evasive steering maneuver, ASC operates to apply the brakes to particular wheels in such a way as to prevent the vehicle from spinning and enable him to safely steer around the obstruction.
A Yaw Rate sensor, which monitors the speed of inertia of the vehicle body, complements the other AYC sensors and enables the computer to monitor body attitude and to judge when the vehicle is about to spin drift out or display other forms of unstable body behavior. At such times, ASC operates to regulate engine output and control breaking force at each wheel individually and thereby avoid a collapse in vehicle body attitude.
