Beschreibung
Zusammenfassung:	A temperature gradient calculation unit calculates a temperature gradient based on the temperature from the temperature sensor and calculates an average temperature based on the temperature gradient. An offset gradient calculation unit calculates an offset value gradient based on the temperature gradient, the average temperature, and the temporary offset value of the angular speed sensor. A correction value calculation unit calculates the offset value of the angular speed sensor based on the offset value gradient and the temperature gradient.
