SYSTEM AND METHOD FOR SEAT VIBRATION CANCELLATION

A method for cancelling seat vibration includes receiving a first accelerometer measurement. The method also includes receiving a second accelerometer measurement. The method also includes determining a counter torque value based on the first accelerometer measurement and the second accelerometer measurement. The method also includes selectively controlling a motor using the counter torque value.

SYSTEM AND METHOD FOR SEAT VIBRATION CANCELLATION

A method for cancelling seat vibration includes receiving, from an accelerometer, a plurality of accelerometer measurements and applying a first filter to the plurality of accelerometer measurements to remove accelerometer measurements of the plurality of accelerometer measurements having a frequency above a first threshold frequency. The method also includes applying a second filter to an output of the first filter to remove accelerometer measurements of the output of the first filter having a frequency above a second threshold frequency and applying a third filter to an output of the second filter to generate an accelerometer measurement output having a center frequency corresponding to a resonant frequency of the vibration of the at least one component of the seat. The method also includes determining an absolute magnitude value of the accelerometer measurement output and selectively controlling a motor based on the absolute magnitude value of the accelerometer measurement output.
