Abstract
A machine control system including an impeller clutch pedal sensor, a power source sensor, a torque converter output speed sensor, an implement lever sensor and a controller is provided. The impeller clutch pedal sensor is configured to generate a signal indicative of an impeller clutch command. The implement lever sensor is configured to generate a signal indicative of a desired hydraulic flow corresponding to an implement lever command. The controller is configured to determine a desired output torque, at a current torque converter output speed, based on the signals from the impeller clutch pedal sensor and the power source sensor. The controller is configured to modulate at least one of the speed of the power source or an engagement of an impeller clutch based on the desired output torque and the implement lever command.
