Abstract
A mount for an earth magnetism sensor device for use in a bearing detecting apparatus which is to be provided on an automotive vehicle adapted to detect a horizontal component of the earth magnetism, characterized in that an axis of detecting a primary direction of the earth magnetism sensor means is offset in the horizontal direction in coincidence with an extent of magnetic declination at a given spot of observation with respect to a desired orientation by way of a map.
Claims3
A method of mounting an earth magnetism sensor adapted to detect a horizontal component of the earth magnetism for a bearing detecting apparatus, on a vehicle, comprising the step of:
- mounting said earth magnetism sensor in a horizontal position within a mount member mounted on a sloped bonnet portion of the vehicle, at a location at which an orientation of magnetic field, which is generated when the vehicle body becomes magnetized, crosses a horizontal plane substantially at a right angle;
- said location being substantially intermediate with respect to the vehicle height, proximal the front end of said vehicle, and substantially at or near a longitudinal center line of said vehicle;
- and
- said earth magnetism sensor being mounted at said location such that an axis of detecting a primary direction of said sensor is horizontally angularly offset by a number of degrees corresponding to a terrestrial magnetic declination at a given observation point with respect to a desired orientation by way of a map.
A method of mounting an earth magnetism sensor adapted to detect a horizontal component of the earth magnetism for a bearing detecting apparatus, on a vehicle, comprising the step of:
- mounting said earth magnetism sensor in a horizontal position within a mount member mounted on a rear trunk cover of a vehicle, at a location at which an orientation of magnetic field, which is generated when the vehicle body becomes magnetized, crosses a horizontal plane substantially at a right angle;
- said location being substantially intermediate with respect to the vehicle height, proximal the rear end of said vehicle, and substantially at or near a longitudinal center line of said vehicle;
