PROBLEM TO BE SOLVED: To accurately detect an acceleration acting on a vehicle even when a deviation from an ideal state occurs in a setting angle of an acceleration sensor.SOLUTION: A control device 6 calculates a deviation from an ideal state of a setting angle of an acceleration sensor 3 by executing a program of correction processing of a detected acceleration of the acceleration sensor 3. A detection value of the acceleration sensor 3 is corrected based on a calculation result. The calculation of the deviation is executed such that a vanishing point V and a horizontal line H are calculated from a photographed image I by a camera 2 and a difference with the vanishing point V and the ideal state of the horizontal state is obtained, thereby calculating the deviation of a setting angle of the acceleration sensor 3. A correction parameter for correcting the detection value of the acceleration sensor 3 is calculated based on the calculated deviation, and an actual detection value of the acceleration sensor 3 is corrected using the correction parameter. |
