ABSTRACT:
An angular velocity sensor wherein an internal temperature of the sensor body is sensed by a temperature sensor and adjusted to be equal to a preset value; an offset value is obtained from an output of the angular velocity sensor at the preset internal temperature with no angular velocity acting thereon and an angular velocity signal at the preset internal temperature is compensated for by the obtained offset value; and also an angular velocity detection signal obtained before the internal temperature reaches the preset value is compensated for by an offset value determined on the base of a value readout from a memory table storing therein characteristic offset values varying with the internal temperature of the sensor body.
