Abstract
A differential limiting control device for a vehicle calculates a yaw rate correspondence control amount according to deviation between actual yaw rate and target yaw rate when a vehicle turns, and also judges the vehicle's steering characteristic of the moment and magnitude relation between wheel speeds of right and left front wheels. The differential limiting control device then applies compensation toward an increase or decrease side based on a yaw rate correspondence control amount to a base control amount according to a combination of the steering characteristic and the magnitude relation between the wheel speeds, and controls a differential limiting force between the right and left front wheels based upon a final control amount obtained after the compensation.
