PURPOSE:To provide a drift correction system which can correct drift even when a vehicle is running. CONSTITUTION:A CPU3 makes a decision whether the output from a gyro, when a vehicle is running, comes between the upper and lower limits when the vehicle is running straight. If it comes between the upper and lower limits, the CPU3 operates a moving average value which is then subtracted from the output of a gyro sensor 1 by means of the subtractor 5 and the difference is fed to a navigation system 9. |
