Yaw rate detection apparatus

摘要

A yaw rate detection apparatus includes: a vehicle yaw rate detection device detecting a yaw rate of a vehicle to output a detection value thereof; a right-wheel and left-wheel speed detection device detecting at least speeds of right and left wheels to output detection values thereof; a wheel speed yaw rate calculation device calculating a wheel speed yaw rate from the detection values of the speeds of the right and left wheels; a turning correction coefficient calculation device calculating a turning correction coefficient based on an amount of turning associated with a turning operation within a predetermined time in which the detection value of the vehicle yaw rate deviates due to a temperature change; and a vehicle yaw rate correction device correcting the detection value of the vehicle yaw rate based on the detection value of the vehicle yaw rate, the wheel speed yaw rate and the turning correction coefficient.
