THROTTLE FILTER SYSTEM AND METHOD
First Claim
1. A method of filtering a targeted frequency from a pedal input signal, the method comprising the steps of:
- sampling the pedal input signal at a sampling frequency;
calculating a moving average of the pedal input signal from samples of the pedal input signal; and
outputting a filtered signal based on the moving average.

Abstract
A method of filtering a targeted frequency from a pedal input signal is provided. The method includes the steps of sampling the pedal input signal at a sampling frequency, calculating a moving average of the pedal input signal from samples of the pedal input signal, and outputting a filtered signal based on the moving average. A throttle filter system is also provided. The system includes a pedal configured to be actuated to set a desired acceleration of a vehicle, a position sensor configured to convert a position of the pedal into an electrical signal, a vehicle driveline configured to accelerate the vehicle, and a filtering module configured to accept the electrical signal from the position sensor and to filter the electrical signal to remove oscillations at a targeted frequency. In the system, the driveline accelerates the vehicle based on the filtered electrical signal.
