Patent ID: 8738251

Claim:
A machine control system comprising: an impeller clutch pedal sensor configured to generate a signal indicative of an impeller clutch command; a power source sensor configured to generate a signal indicative of a speed of a power source; a torque converter sensor configured to generate a signal indicative of a current torque converter output speed; an implement lever sensor configured to generate a signal indicative of an implement lever command; and a controller in communication with the impeller clutch pedal sensor, the implement lever sensor, the torque converter sensor and the power source sensor, the controller being configured to: determine a desired output torque, at the current speed of the torque converter output speed, based on the signals from the impeller clutch pedal sensor and the power source sensor; determine a first required speed of the power source, at the current torque converter output speed, corresponding to the desired output torque; determine a second required speed of the power source corresponding to the implement lever command; compare the first and second required speeds of the power source; select a higher of the first and second required speeds as the desired speed of the power source; and modulate at least one of the speed of the power source or an engagement of an impeller clutch based, at least in part, on the desired speed of the power source and the implement lever command.
