Powertrain output monitor
First Claim
1. A method of monitoring the powertrain output controller for an internal combustion engine responsive to an accelerator pedal input, said engine having at least one fuel injector responsive to a commanded fuel signal and an engine speed sensor for providing an engine speed signal, the method comprising the steps of:
- determining the accelerator pedal position;
generating a desired fuel quantity value as a function of the accelerator pedal position; and
if the commanded fuel signal is greater than the desired fuel quantity value, then generating a commanded fuel signal equal to the desired fuel quantity value.

Abstract
A powertrain control method for an internal combustion engine responsive to an accelerator pedal input, the engine having at least one fuel injector responsive to a commanded fuel signal. The method comprises the steps of determining the engine speed, determining the accelerator pedal position, and generating a desired fuel quantity value as a function of the accelerator pedal position and engine speed. If the commanded fuel signal is greater than the desired fuel quantity value, the commanded fuel signal is limited to the desired value.
