When the driving force between a driven wheel of a wheel and the surface on which the vehicle is travelling exceeds the available traction, wheel slippage may occur. Wheel slippage may result in a loss of control of the vehicle. The present disclosure may facilitate the control of drive power sent to a driven wheel of a vehicle from consideration of a torque setting and a speed of the vehicle.

Method and apparatus for controlling the drive power of a vehicle

An engine command override may occur when a diesel particulate filter (DPF) requires regeneration. The need for regeneration may be indicated by regeneration level. The engine may be operated in a normal mode when the DPF regeneration level is below a regeneration level threshold, wherein the engine command is based on the throttle input. Additionally, the engine may be operated in an override mode when the DPF regeneration level is above a regeneration level threshold and the engine is operating in the idle state, wherein the engine command is based on a predetermined throttle regeneration setting.

Engine control system and method for initiating a diesel particulate filter regeneration

An automatic shut down system for a machine having an engine and a work implement is disclosed. The automatic shut down system may have a position sensor, which may be associated with the work implement. The position sensor may be configured to generate a position signal indicative of a position of the work implement. The automatic shut down system may also have a controller, which may be in communication with the position sensor. The controller may be configured to shut down the engine, based on the position signal.

Automatic shut down system for machine having engine and work implement

A performance management system for use a plurality of machines operating at a common worksite is disclosed. The performance management system may have at least one data acquisition module configured to monitor performance of the plurality of machines, and a controller in communication with the at least one data acquisition module. The controller may be configured to collect machine performance data from the at least one data acquisition module, and detect a performance irregularity based on the collected machine performance data. The controller may be further configured to analyze the collected machine performance data, and determine which of a machine condition, an operator condition, and a site condition is the predominant cause of the performance irregularity based on the comparison.

Performance management system for multi-machine worksite

A machine includes a plurality of electronic controllers electrically connected to an electrical power source along a first electrical circuit through a first relay and along a second electrical circuit through a second relay. A relay controller is directly connected to the electrical power source along a third electrical circuit, and is in communication with the first relay and the second relay. The relay controller is configured to open or close the first relay or the second relay in response to a power requirement indication.
