To provide a device for correcting acceleration in two axial directions detected by a biaxial acceleration sensor to acceleration in a vehicle traveling direction and a vertical direction.SOLUTION: A device 10 includes a processing section 11. The processing section corrects the influence of the pitch angle from the Xs axis and the Zs axis acceleration based on the Xs axis acceleration value output by an acceleration sensor 1 in a reference state in which the vehicle is stationary on a plane perpendicular to the vertical direction, thereby obtaining the first correction Xs axis and the Zs axis acceleration. The processing section calculates the second correction Zs axis acceleration by correcting the influence of the roll angle from the first correction Zs axis acceleration based on the value of the Zs axis acceleration output from the acceleration sensor 1 in the reference state. The processing section corrects the influence of the yaw angle from the first correction Xs axis acceleration based on the reference acceleration in the Xc axis direction which is output from the acceleration sensor 2 and corrected, thereby obtaining the second correction Xs axis acceleration.SELECTED DRAWING: Figure 7
