PURPOSE: To reduce the accumulation of the error of detection in an azimuth detecting device for a vehicle for detecting the quantity of angular change or the azimath of a vehicle by integrating the difference between the detected value of a rate gyro for detecting angle velocity and a reference value.
CONSTITUTION: In an azimuth detecting device for a vehicle which is provided with a gyroscope 13 for detecting angular velocity in the change of the azimuth of a vehicle, a processing means 5 for integrating the difference between the sampled value of the detected value of the gyroscope 13 and the reference value preliminarily stored to seek the azimuth of a vehicle, and a stoppage detecting means 12 installed in a vehicle for detecting whether a wheel to rotate in contact with the ground while a vehicle is driving. The processing means 5 stores the mean value of the sampled value of the detected value of the gyroscope 13 while the wheel is stopping for a reference value on the basis of the detected information of the stoppage detecting means 12. Also, in order to measure the distance of the travel motion of a vehicle. A detecting means for the quantity of rotation of a wheel for detecting the quantity of rotation of the wheel is provided and used in common for the stoppage detecting means 12.
