More Information
Summary:Provided is a yaw rate detection device comprising: a vehicular yaw rate detection means for detecting the yaw rate of a vehicle and outputting a detection value; a left/right wheel speed detection means for detecting the wheel speed of at least left and right wheels and outputting a detection value; a wheel speed yaw rate calculation means for calculating a wheel speed yaw rate from the detection value of the speed of the left and right wheels; a rotation correction coefficient calculation means for calculating a rotation correction coefficient that is based on the amount of rotation occurring in a rotation operation during a predetermined time period in which the detection value of the vehicular yaw rate deviates due to a temperature change; a vehicular yaw rate correction means for correcting the detection value of the vehicular yaw rate, in accordance with the vehicular yaw rate detection value, the wheel speed yaw rate, and the rotation correction coefficient.
