摘要： A system for re-orienting a machine during a ripping operation includes a position sensing system, a ripper, and a controller. The system stores a ripping path, determines the position of the machine, and compares the position of the machine to the ripping path. A drawbar pull of the machine is determined, compared to a maximum steering drawbar pull, and the ripper is raised if the machine is positioned greater than a predetermined distance from the ripping path and the drawbar pull exceeds the maximum steering drawbar pull. The machine is re-oriented and the ripper lowered relative to the work surface.

摘要： Machines, such as large tractors used in earthmoving, operate in a cycle of pushing forward and reversing to a starting point. The net performance of the machine is a function of the speed at which the reverse segment is performed. Generally, using the highest gear for reverse accomplishes the goal of the fastest return. However, some high slope grade conditions may result in higher speeds using lower gears. A combination of slope, track speed vs. drawbar pull, and track slip may be used to recommend a gear and track speed with the greatest ground speed for reverse operation.

摘要： A braking system is disclosed. The braking system may include a controller configured to determine a speed threshold that is based on a deceleration of an output speed of a powertrain of a machine caused in part by engagement of one or more brakes of the machine during a directional shift in a movement of the machine, the speed threshold being the output speed of the powertrain at which the one or more brakes are to be commanded to disengage. The controller may be configured to command disengagement of the one or more brakes based on a determination that the output speed of the powertrain satisfies the speed threshold.

摘要： 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.

摘要： A work machine is disclosed. The work machine may include a frame, an implement system coupled to the frame, one or more sensing devices, and a control unit in communication with the implement system and the one or more sensing devices. The one or more sensing devices may be configured to transmit sensing device data relating to an operation of the implement system. The control unit may receive the sensing device data, compare the sensing device data with a stall threshold, and initiate a stall timer based on determining that the sensing device data satisfies the stall threshold. The stall timer may be configured to measure a stall duration. The control unit may compare the stall duration with a duration threshold, identify a stall event based on determining that the stall duration satisfies the duration threshold, and cause an action to be performed based on the stall event.

摘要： 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.
