Abstract: PURPOSE:To provide a compensator which performs removal of offset by getting the offset of a detection system for the quantity of vehicle yaw motion state appropriately besides the time of stoppage of a vehicle and the time of rectilinear running. CONSTITUTION:This compensator has a yaw rate estimate computing means 6, which computes the yaw rate estimate from the physical relation of vehicle motion, a computing means 7, which computes the quantity of offset of the detection value form the difference between the estimate and the yaw rate detection value from the yaw rate detection means 7, and a yaw rate compensating means 8 which removes the quantity of offset of the detection means 7 by the difference between the detection value and the computed value of the quantity of offset.
