Abstract:
1. A throttle control system comprising: a throttle having a throttle actuator coupled to a throttle plate; and a control module that is coupled to the throttle actuator that sends a first signal within a gear change time period to the throttle actuator to position the throttle plate for an increased throttle opening, that terminates the first signal after the gear change time period, that sends a second signal to the throttle actuator to position the throttle plate, that positions the throttle plate by the throttle actuator to attain a lower throttle opening limit, and that downshifts from a higher gear to a lower gear, wherein the gear change time period extends to one of a commanded gear change, a maximum time limit, and an actual gear change and wherein the control module determines a throttle opening limit based upon a difference between a transmission commanded gear turbine revolutions per minute (RPM) and an engine RPM.
