Abstract
A power system is disclosed as having a power source, a transmission configured to receive a torque output from the power source and to drive a traction device, and an operator input device. The power system may also have a controller configured to reference a signal from the operator input device with a map stored in memory to determine a corresponding speed of the power source, and to determine a margin between an actual and a maximum available torque output of the power source at a current speed. The controller may also be configured to selectively adjust a speed of the power source mapped to the maximum displaced position of the operator input device based on the margin, and to selectively adjust fueling of the power source at a current displacement position of the operator input device and operation of the transmission based on the signal and map.
