PROBLEM TO BE SOLVED: To provide a technique that increases the accuracy of deriving an angular velocity even in a short period of time.SOLUTION: A temperature inclination calculation part 72 calculates the inclination of a temperature based on a temperature from a temperature sensor and calculates an average temperature based on the inclination of the temperature. An offset inclination calculation part 76 calculates the inclination of an offset value based on the inclination of the temperature, the average temperature, and a temporary offset value of an angular velocity sensor. The correction value calculation part 78 calculates the offset value of the angular velocity sensor based on the inclination of the offset value and the inclination of the temperature.SELECTED DRAWING: Figure 3

    【課題】短期間であっても角速度の導出精度を向上させる技術を提供する。【解決手段】温度傾き算出部72は、温度センサからの温度をもとに温度の傾きを算出するとともに、当該温度の傾きをもとに平均温度を算出する。オフセット傾き算出部76は、温度の傾きと平均温度と、角速度センサの仮のオフセット値をもとに、オフセット値の傾きを算出する。補正値算出部78は、オフセット値の傾きと、温度の傾きとをもとに、角速度センサのオフセット値を算出する。【選択図】図3
