Abstract: A method for identifying a mode of failure in a pump includes receiving and recording a first set of flow rate pressure values over a specified time period to determine an existing hydraulic signature of the pump. The method then includes receiving and recording real-time flow rate pressure values over a subsequent period of time to determine a current hydraulic signature of the pump. The method further includes comparing the real-time flow rate pressure values to the first set of flow rate pressure values to detect variances in the hydraulic signature and output a mode of failure for the pump.

Abstract: An adaptive control system for a machine implement is provided. The adaptive control system includes a machine implement of a machine and an adaptive controller operatively coupled to the machine implement. The adaptive controller includes a processor configured to receive a position of the machine implement relative to a terrain from at least one position detection system, receive data regarding operating conditions of the terrain, compare the position with a target position stored in a memory, compare the data regarding the operating conditions with data stored in a reference model of the terrain stored in the memory, and adjust the position of the machine implement based upon the comparisons and based upon an updated reference model of the operating conditions of the terrain.

Abstract: In an engine system of a machine having a multi fuel engine system, the occurrence of transient events such as gear shifts, grade changes and machine speed changes may be anticipated, and a fuel substitution strategy may be adjusted if necessary to optimize performance during the transient events. Transient events at a worksite may be anticipated and mapped by evaluating shift control logic strategies and worksite maps with truck route, speed and topographical information and determining where the fuel substitution strategy cannot meet the power requirements for the transient event. When it is determined that the machine is approaching an anticipated transient event, an appropriate fuel substitution adjustment can be executed to ensure the engine has sufficient power for the transient event.

Abstract: A vehicle includes an automatic transmission and a set of sensor inputs providing values indicating a current operational status of the vehicle pertinent to controlling the automatic transmission. The set of sensor inputs include: engine speed, engine torque, current transmission gear; and vehicle speed. The vehicle includes a programmed processor configured to iteratively and co-dependently generate a vehicle mass parameter value and a grade of incline parameter value. The programmed processor, when generating the vehicle mass parameter value and the grade of incline parameter value, uses a set of parameters including: a propulsive force driving the vehicle; a set of forces acting on the vehicle resisting forward movement, and an observed rate of change of a speed of the vehicle.
