車両用方位検出装置。[Scope of claim for utility model registration] Absolute direction detection means that detects the absolute direction of the vehicle by detecting the earth's magnetism, and relative direction detection means that detects the rotation speed of the left and right wheels and calculates the relative direction from the rotation speed difference between the left and right wheels and the distance traveled by the vehicle. A vehicle orientation device for detecting the traveling direction of a vehicle, comprising: a relative orientation calculation means for calculating the orientation; and a composite orientation calculation means for calculating a composite orientation obtained by combining the absolute orientation and the relative orientation at a predetermined ratio. The composite azimuth calculating means includes a composite ratio control means for reading an activation signal of the electronic skid control and calculating the traveling heading of the vehicle only from the absolute azimuth while the electronic skid control is in operation. Features of vehicle orientation detection device.
