ABSTRACT:
A small and inexpensive bearing-distance sensor capable of detecting a travel bearing and a travel distance of a vehicle. The bearing-distance sensor includes a rectangular parallelepiped case. A first acceleration sensor and a second acceleration sensor are mounted within the case. The first acceleration sensor detects an acceleration in a first direction, e.g. the longitudinal direction of the case, to obtain a signal related to the acceleration, and the second acceleration sensor detects a force applied in the width direction of the case, which is perpendicular to the first direction, to obtain a signal related to that force. The travel distance of the vehicle is found from the output signal of the first acceleration sensor, and the travel bearing of the vehicle is found from the output signals of the first and second acceleration sensors.
