First Claim
1. A steering wheel turning angle detector for a vehicle, comprising:
- a steering wheel turning angle sensor attached to a steering wheel for detecting a steering wheel turning angle and outputting a steering angle value;
yaw rate detecting means for detecting a yaw rate of the vehicle and outputting a yaw rate thereof;
steering wheel turning angle predicting means, receiving an output from said yaw rate detecting means, for outputting a predicted steering angle value in response to the detected yaw rate; and
steering wheel turning angle value correcting means, receiving output signals from said steering wheel turning angle sensor and said steering wheel angle predicting means, for correcting said steering angle value of the steering wheel turning angle sensor as a detected steering wheel angle which is corrected in response to an error between outputs from said steering angle value and said predicted steering angle value.
