Abstract
A gyro sensor apparatus includes a driving section that supplies a driving signal, which is for vibrating a sensing element of a vibration-type gyro sensor in a drive axis direction, to the sensing element, and a processing unit that receives a first vibration signal having an amplitude proportional to a driving vibration amplitude, which is an amplitude of vibration in the drive axis direction of the sensing element and a second vibration signal having an amplitude proportional to Coriolis force generated in the sensing element due to an angular velocity of the sensing element. The processing unit is configured to calculate a ratio of Coriolis force to the driving vibration amplitude based on the first vibration signal and the second vibration signal and output a result of the calculation as a result of detection of the angular velocity of the sensing element.
