ABSTRACT:
A throttle position system for an internal combustion engine. Included is a method for filtering a throttle position sensor using a maximum allowable rate of change based on factors such as, for example, physical driver limits or physical electronic actuator limits, for rejecting noise spikes. The filtered signal retains the necessary lead for use in air/fuel ratio control while eliminating problems associated with large noise spikes. Fuel is supplied based on the filtered throttle position and measurements from either a mass air flow sensor or a manifold pressure sensor.
