PURPOSE:To correct exactly a magnetization of a bearing sensor without depending on a rotation radius of a vehicle and a rotating speed of a wheel, detecting a running bearing of the vehicle, and decomposing this detecting output into components of two directions orthogonal to an earth magnetism. CONSTITUTION:A car body magnetization correcting system detects a running bearing of a vehicle, and each detecting signal of a bearing sensor 2, which is outputted by decomposing this detecting output into components of two directions orthogonal to an earth magnetism is supplied to an operation control part 6 through a multiplexer 4, and also through an analog-to-digital convertr 5. Also, as for the operation control part 6, a correction start switch 7 for giving a correcting command for correcting a magnetized component of a car body, and a correction end switch 8 for commanding the end of the correction are connected. According to a system of such a constitution, a magnetization of the bearing sensor can be corrected exactly without depending on a rotation radius of the vehicle and a rotating speed of the wheel. |
