Abstract
Abstract A steering wheel turning angle detector for a vehicle comprises a steering wheel turning angle sensor (2) attached to a steering wheel (H) to detect a steering wheel turning angle, yawing detecting means (3) for detecting the yawing state of the vehicle, steering wheel turning angle presuming means (4) for presuming the steering wheel turning angle from the yawing state, and steering wheel turning angle correcting means (5) for correcting the output value of the steering wheel turning angle sensor on the basis of an error between the output signals of the steering wheel turning angle sensor and the steering wheel turning angle presuming means. A method for controlling yawing of a vehicle on the basis of the output of a steering wheel turning angle sensor (2) attached to a steering wheel (14) comprises the steps of presuming a steering wheel turning angle, and gradually correcting the output value of said steering wheel turning angle sensor (5), on the basis of an error between said presumed steering wheel turning angle (δp) and the detected steering wheel turning angle (S) over a predetermined period of time. Thus, an accurate steering wheel turning angle can be obtained irrespective of the attaching state of the steering wheel turning angle sensor to the steering wheel.
