<P>PROBLEM TO BE SOLVED: To provide a vehicle-mounted apparatus equipped with an acceleration sensor in which acceleration in the reference axes directions can be detected with high precision even when the mounting position and mounting angle of the acceleration sensor are freely selected. <P>SOLUTION: The vehicle-mounted apparatus comprises a plurality of acceleration sensors 11p, 11q, 11r of which the directions of sensitive axes p, q, r are different and a control section 12 for calculating values of acceleration acting in the directions of the reference axes X, Y, Z on the basis of angle information related to angles between the reference axes X, Y, Z and the sensitive axes p, q, r of the acceleration sensors 11p, 11q, 11r and values of acceleration detected by the acceleration sensors 11p, 11q, 11r. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
