ABSTRACT:
An apparatus for controlling a differential limit torque produced in a differential provided in an automotive vehicle. During vehicle deceleration, a required differential limit torque value is calculated based on the vehicle deceleration. When a decrease is detected in the required differential limit torque value, a target value for the differential limit torque is calculated based on the required differential limit torque value through a filtering process employing a first filter having a slow output response with respect to the required differential limit torque value decrease in the presence of vehicle braking or a second filter having a fast output response with respect to the required differential limit torque value decrease in the absence of vehicle braking. The differential limit torque is controlled to the calculated target value.
