A small and inexpensive bearing-distance sensor (1) capable of detecting a travel bearing and a travel distance of a vehicle is provided. The bearing-distance sensor (1) includes a rectangular parallelepiped case (2) for example. A first acceleration sensor (10a) and a second acceleration sensor (10b) are mounted within the case (2). The first acceleration sensor (10a) detects an acceleration in one direction, e.g. the longitudinal direction of the case (2), to obtain a signal related to the acceleration and the second acceleration sensor (10b) detects a force applied in the width direction of the case (2), which is perpendicular to said one 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 (10a) and the travel bearing of the vehicle is found from the output signals of the first and second acceleration sensors (10a) and (10b). <IMAGE> |
