Abstract
Real time determination of current vs. optimum performance in a track-type tractor is complex and requires information about both a state of the tractor and the operating environment, such as soil conditions. Presenting such data to an operator creates a problem of conveying sufficient information without undue complexity. A three part display for an operator shows a full range of performance, a subset range of performance associated with peak performance that is overlaid on the full range of performance, and a current performance indicator also overlaid on the full range of performance, such that peak performance is achieved when the current performance indicator is centered on the subset range of performance. The subset range of performance may move over the full range of performance to indicate operating conditions favoring a particular condition, e.g., low slip. An operator may then effect a change by adjusting, for example, speed or load.
