20140156105 | Conditioning a Performance Metric for an Operator Display - 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. | 06-05-2014 |
20140156152 | Determining an Optimum Operating Point of an Earth Moving Machine - Optimum performance in an earth moving machine, such as a track-type tractor, is a function of many complex factors such as power delivered to the tracks, load, soil type, soil conditions, speed, terrain, etc. To determine an operating point associated with optimum performance, operational data may be collected, processed, and applied to known performance curves for well characterized conditions to develop recommended operating conditions. A coefficient of traction and a shear modulus adjustment, reflecting surface conditions, are calculated at the tractor during operation and used to offset a table of ideal condition operating points for use in soil characterizations. Using this and other inputs, a cycle power equation gives a curve that peaks at a theoretical optimum performance. However, the number of variables make an analytic solution impossible. An iterative approach determines a range of operating conditions associated with optimum performance. | 06-05-2014 |
20140156162 | Measuring and Displaying Tractor Performance - A method of measuring and displaying track-type tractor performance in real time calculates both a measure of work performance and a theoretical optimum work performance for a given input state, such as track speed. After estimating soil conditions, the theoretical optimum is estimated using an iterative technique. The optimum and current performance are normalized and displayed using a first bar representing a full range of work performance, a second bar depicting a range of optimum performance for current conditions is presented overlying the first bar, and an indicator line showing the current performance. This allows an operator to adjust speed or load accordingly. A coefficient of traction and a shear modulus adjustment, reflecting soil conditions, are calculated at the tractor during operation and used to offset a table of ideal condition operating points to produce the second bar. | 06-05-2014 |
