Abstract: PURPOSE:To realize high accuracy in detecting acceleration with a simple structure by a method wherein acceleration can be obtained with error component in acceleration based on oscillation of a vehicle eliminated only by using two acceleration sensors with respect to a direction of the acceleration to be detected. CONSTITUTION:At two different points above the oscillation axis YC of a vehicle, that is, at a first acceleration point and a second acceleration point, acceleration in a direction for crossing the vertical plane VP including the oscillation axis YC is detected by first and second acceleration detectors M1 and M2 respectively. Then an acceleration compensating device M3 compensates the detected acceleration based on a distance from the oscillation axis YC to the first acceleration detected point and a distance from the oscillation axis YC to the second acceleration detected point respectively, from the detection results of the acceleration detectors M1 or M2 with rotating acceleration component generated in terms of the oscillation axis as the center eliminated. Thus error components based on the oscillation contained in the detected acceleration of the detectors M1 and M2 are offset and true acceleration components can be obtained.
