ABSTRACT:
A throttle control method includes generating a throttle request based on a drag torque request and setting a throttle command equal to the throttle request when the throttle request is less than a throttle idle maximum. A throttle maximum increase is determined when the throttle request is greater than the throttle idle maximum and the throttle command is determined based on the throttle maximum increase. The throttle is controlled based on the throttle command.
