Abstract: PURPOSE:To prevent a wrong offset bias compensation and to improve the accuracy for determining the position of own vehicle by compensating the detection result of a sensor only when the offset bias value estimated based on the detection result of a relative azimuth sensor matches predetermined conditions. CONSTITUTION:When the angle velocity detected by a relative angle sensor 12 is input to a bias estimation means 1a and vehicle stop is confirmed by the detection data of a vehicle speed sensor 13, detected angular velocity is integrated. Then, when the integration count is equal to or more than a specific count, the average value of the angular velocity is calculated to obtain an offset bias. When the offset bias is equal to or less than a specific value (a value which cannot be output when the sensor 12 is normal and is still), a bias compensation means 16 uses it as the compensation value of angular velocity. Otherwise, the means 16 judges that the sensor 12 outputs an abnormal value and hence does not update the compensation value. The angular velocity detected at the succeeding measurements is compensated by the amount of compensation when the vehicle drives.
