Claim 9:
10. The control system according to claim 7, wherein the first sensor and the second sensor are gravitational sensors, the first directional data has a first component on an X1 axis, a second component on a Y1 axis and a third component on a Z1 axis; the second directional data has a fourth component on an X2 axis, a fifth component on a Y2 axis and a sixth component on a Z2 axis; the preprocessor calculates a first angle relative to the Z1 axis in accordance with a gravitational acceleration and the third component, and calculates a first inclined angle relative to the Y1 axis in accordance with the gravitational acceleration, the first angle and the second component; and the preprocessor calculates a second angle relative to the Z2 axis in accordance with the gravitational acceleration and the sixth component, calculates a second inclined angle relative to the Y2 axis in accordance with the gravitational acceleration, the second angle and the fifth component, and obtains the difference value based on difference between the first inclined angle and the second inclined angle.
