ABSTRACT:
In an apparatus for detecting a driving azimuth of a vehicle, a gyroscopic sensor signal and a geomagnetic sensor signal are acquired. When the vehicle is driven in a disturbed geomagnetic area such as a straight road, the acquired geomagnetic sensor signal does not correctly reflect the actual driving azimuth of the vehicle. Moreover, the gyroscopic sensor signal drifts over time. When the vehicle is in such a disturbed geomagnetic area, a variation amount in the acquired geomagnetic sensor signals is subtracted from another variation amount in the acquired gyroscopic sensor signals to obtain a driving azimuth similar to the actual driving azimuth.
