Method for determining gyroscope bias using rotation rate data
A recently granted patent (Publication Number: US11898874B2) discloses a method for determining the current estimated gyroscope bias of a gyroscope based on rotation rate data. The method involves receiving rotation rate data from the gyroscope, calculating rotation rate moving averages and moving standard deviations, and updating the estimated gyroscope bias if certain conditions are met. The patent also covers the calculation of separate moving averages and standard deviations for different axes of rotation, ensuring accurate bias estimation for each axis. Additionally, the method includes factors such as moving average forget rate and moving standard deviation forget rate to enhance the accuracy of the bias estimation process.
Furthermore, the patent extends to a mobile device comprising a gyroscope and a processor configured to implement the method described. The processor receives rotation rate data from the gyroscope, calculates moving averages and standard deviations, and updates the estimated gyroscope bias accordingly. The mobile device is designed to handle rotation rate data from multiple axes, ensuring precise bias estimation for each axis. By incorporating factors like moving average forget rate and moving standard deviation forget rate, the mobile device can effectively determine and update the gyroscope bias, enhancing the overall performance and accuracy of the gyroscope system.
