PURPOSE:To obtain an acceleration detection device with simple configuration and at low cost. CONSTITUTION:Acceleration sensors 1 and 2 provided with detection axes an and a2 inclined at thetas against an installation plane P are used. If the installation plane P is inclined against horizontal plane H, in the case acceleration a is applied in horizontal direction, the component of gravitational acceleration appears besides the component of acceleration alpha in the detection value of the acceleration sensors 1 and 2. Based an the detection values of the acceleration sensors 1 and 2, numeral calculation is performed, so that, inclination thetap of the installation plane P against the horizontal plane H is detected, and influence of gravitational acceleration is excluded. |
