MOBILE BASE INFORMATION DETECTING METHOD AND MOBILE BASE INFORMATION MULTI-SENSOR AND ACCELERATION SENSOR

摘要

A mobile base information multi-sensor (S) which is provided with first and second g-φ sensors (50, 51) having basically the same structure, wherein the first and second g-φ sensors (51, 52) are disposed on a substrate (52) so that relative torsion bars are along the vertical direction and virtual lines (refer to dotted lines in the figure) passing the centers of respective g-φ sensors (50, 51) cross perpendicularly each other in a direction perpendicular to the torsion bars, whereby the directions and magnitudes of acceleration, angular velocity and angular acceleration acting on the vehicle (M) can be determined by comparing capacitance outputs from respective sensors (50, 51) with each other.
