Publication number: 20230136373Abstract: A method for dynamic error compensation of a position sensor and a position sensor are disclosed. In the method, a calculated speed of a moving target for a current determined position is compared to a calculated running average of the speed of the moving target over a certain number of determined positions and if the calculated speed of the moving target for the current position is within a first window around the calculated running average of the speed of the moving target over the certain number of determined positions the dynamic angle error is not re-calculated for the current determined position, and/or if the calculated speed of the moving target for the current determined position exceeds a second window the previously calculated running average is deleted and the calculation of the running average of the speed of the moving target over a certain number of determined positions is restarted.Type: ApplicationFiled: October 20, 2022Publication date: May 4, 2023Applicant: Renesas Electronics America Inc.Inventor: Ruggero LEONCAVALLO
