Abstract
A method for determining a coefficient gain to a signal command to actuate an air intake throttle plate to ensure that the throttle plate responds in a desired manner within a desired responsiveness with relative conformity over the life of the air intake manifold with out losses due to variability in spring/motor/friction responsiveness in the throttle plate actuator. The coefficient gain is multiplied to successive throttle plate command signals to ensure the throttle plate responds as desired. The coefficient gain is re-determined periodically when it is determined that the throttle plate responsiveness does not meet desired throttle plate responsiveness.
