<p>PROBLEM TO BE SOLVED: To provide a turning state quantity detection apparatus configured to detect turning state quantity of a vehicle accurately even if detection gain deviation is generated in a sensor.SOLUTION: A turning state quantity detection apparatus calculates a reference yaw rate YR2 of a vehicle, on the basis of a vehicle speed and a radius of a road (S30), regarding a plurality of turning states different each other in at least one of the vehicle speed and radius of the road, calculates a detection gain G1 of a yaw rate sensor (S50), on the basis of a yaw rate YR1 of the vehicle detected by the yaw rate sensor on each of the turning states and the reference yaw rate YR2 of the vehicle, calculates a correction coefficient Ka (S60) by use of a ratio G0/G1 between the detection gain G1 and a standard gain G0 set in advance for the yaw rate sensor, and corrects the yaw rate YR1 of the vehicle detected by the yaw rate sensor, with the correction coefficient Ka (S80).</p> |
