Abstract
An apparatus for estimating a slip angle in a wheeled vehicle having a set of front road wheels and a set of rear road wheels, including the same kind of wheel speed sensors arranged to detect each rotation speed of the road wheels for producing wheel speed signals respectively indicative of the detected rotation speeds of the road wheels, and a microcomputer responsive to the wheel speed signals from the sensors for calculating a first difference in speed between the front and rear road wheels and a second difference in speed between the left and right road wheels and for calculating a ratio of the first difference in speed relative to the second difference in speed for estimating the calculated ratio as a slip angle of the vehicle.
