PURPOSE:To obtain the real angular velocity rid of fluctuation elements by removing characteristic fluctuation generated in association with the temperature fluctuation and the lapse of time, from the output of an angular velocity sensor. CONSTITUTION:An arithmetic part 7 integrates the digital value D1. corresponding to a signal omega generated at a sensor part body 1 every specified sampling period and outputs an angle signal phi. Data Ks (T) and B(T) corresponding to the temperature T measured by a temperature sensor 8 are read from look-up tables 10, 11. The arithmetic part 7 performs correction on the basis of the data D1, Ks(T), B(T) and the time elapsed data from the measurement starting time so as to compute the real angle PHI. The characteristic fluctuation generated in association with the temperature fluctuation and the lapse of time is thus removed from the output of an angular velocity sensor so as to obtain the real angular velocity or the angle rid of these fluctuation elements. |
