PROBLEM TO BE SOLVED: To improve detection accuracy of a tilt angle in a tilt angle detector of a movable body, even when the movable body is placed on an excessively inclined road surface.SOLUTION: Controlling means (22) is provided with: high frequency attenuation value calculating means (22B) which calculates a high frequency attenuation value by using an attenuation output signal from a low-pass filter (20) and has a time constant of the low-pass filter (20); and time constant changing means (22C) which, when the speed of a movable body (1) detected by speed detecting means (21) is less than a prescribed value (V), changes the time constant of the low-pass filter (20) in the high frequency attenuation value calculating means (22B) to a value (B) smaller than a value (A) at the time when the speed of the movable body (1) detected by the speed detecting means (21) is equal to or higher than the prescribed value (V). |
