Japan, Feb. 24 -- TOHOKU UNIV has got intellectual property rights for 'GYRO DEVICE AND CONTROL METHOD FOR GYRO DEVICE.' Other related details are as follows:
Application Number: JP,2022-030741
Category (FI): G01C19/5677
Stage: PROBLEM TO BE SOLVED: To provide a gyro device capable of correction according to a mismatch of a two-dimensional oscillator while detecting an angular velocity.SOLUTION: A gyro device includes: a single two-dimensional oscillator 15 that is driven by a drive signal corresponding to a first rotation oscillation mode and a drive signal corresponding to a second rotation oscillation mode, and outputs an output signal corresponding to the first rotation oscillation mode and an output signal corresponding to the second rotation oscillation mode; a first modulation processing unit 301 that modulates an amplitude of the drive signal corresponding to the first rotation oscillation mode by a first modulation method; a second modulation processing unit 501 that modulates an amplitude of the drive signal corresponding to the second rotation oscillation mode by a second modulation method; a first demodulation processing unit 401 that demodulates a first error composition corresponding to the second rotation oscillation mode by a first demodulation method corresponding to the first modulation method; and a second demodulation processing unit 601 that demodulates a second error composition corresponding to the first rotation oscillation mode by a second demodulation method corresponding to the second modulation method.SELECTED DRAWING: Figure 29 (Grant)
