Abstract
A method of controlling fuel input to an engine of a vehicle. A feedback signal is received from a sensor that senses engine exhaust. A dither signal having the same frequency as the feedback signal is applied to a fuel control signal controlling fuel to the engine. A proportional/integral correction is applied to the fuel control signal based on the frequency.
