Description of the Related Art Conventionally, when the acceleration of a moving body in the traveling direction is detected, it is obtained from the rotational displacement of a gyro attached to the moving body and the acceleration in the three-dimensional direction. I didn't need it, but I needed a gyro and three sets of accelerometers for this. When the acceleration in the traveling direction is obtained by an accelerometer installed in the traveling direction without using a gyro, it is necessary to detect the gradient of the moving body course. In this case, the rotational displacement of the gyro and the 3
A complicated calculation process is performed from the acceleration in the dimensional direction to obtain the gradient of the moving body path.

を検出することができる。Action: Gravity acts on the accelerometer mounted on the moving body that travels along a sloped course, and the accelerometer indicates a value including a deviation from the acceleration in the traveling direction according to the gradient.
On the other hand, the acceleration of the rotation pulse generator for the axle mounted on the moving body correctly indicates the acceleration in the traveling direction of the moving body. This difference has a constant relationship with the gradient, and the gradient of the moving body path can be detected by a simple arithmetic process without using an expensive gyro.

And the component force in the gradient direction, and the relationship shown in equation (1) holds. α ′ = α + g · sin θ (1) The gradient θ can be calculated from the equation (1).

正確に補正することができる。Since the gradient is detected by using the rotary pulse generator and the accelerometer of the axle mounted on the moving body,
It is economically superior because there is no need to install a new expensive gyro. Further, it becomes possible to continuously detect the gradient of the moving body path with high accuracy. Furthermore, the acceleration in the traveling direction of the moving body is obtained by the gradient and the accelerometer that are obtained in advance, and even when the rotation of the axle includes slipping or idling, this can be accurately corrected.
