Vibration-type angular velocity sensor with interchangeable control functions
A recently granted patent (Publication Number: US11982531B2) discloses a vibration-type angular velocity sensor comprising two angular velocity sensor units. The second unit includes a vibrator, primary side control circuit inducing primary vibration, and a secondary side control circuit detecting secondary vibration due to angular velocity. The sensor is designed to interchange the functions of the control circuits to detect angular velocity based on secondary vibration. The first unit calculates a bias component based on detection results from both units in a predetermined period, enhancing accuracy and reliability in angular velocity detection.
Furthermore, the patent details the configuration for calculating the bias component, ensuring consistency and precision in sensor readings. The predetermined period includes distinct phases for detecting angular velocity using different control circuits, maintaining a constant bias component for improved performance. The sensor units are equipped with primary and secondary control circuits, fixed functions for inducing primary vibration and detecting secondary vibration, respectively. By integrating detection results from both units, the sensor calculates bias components accurately, enhancing the overall efficiency and reliability of the angular velocity sensor.
