Embodiment Construction

[0014] figure 1 is a diagram of an exemplary machine 100 described herein. Machine 100 includes engine 110 , engine control module (ECM) 112 , sensor system 120 , operator interface 130 , and electronic control unit (ECU) 140 .

[0015] Engine 110 may include an internal combustion engine, such as a compression ignition engine, a spark ignition engine, a laser ignition engine, a plasma ignition engine, or the like. As described herein, engine 110 provides power to machine 100 and / or a set of loads associated with machine 100 (eg, one or more components that absorb power and / or use power to operate). For example, engine 110 may provide power to a drive system (e.g., a powertrain including a transmission, drive shafts, differentials, torque converters, gear drives, one or more ground engaging implements, etc.) to enable maneuvering of machine 100 .

[0016] Engine 110 may provide power to implements of machine 100 , such as implements used in mining, construction, farming, tr...

Abstract

An electronic control unit of an engine control module controlling an engine is disclosed. An electronic control unit may receive power command information associated with a load of an engine from a load monitoring device. The electronic control unit may determine a total power command for the engine based on the power command information. The electronic control unit may determine a target engine speed of the engine based on the total power command. The electronic control unit may cause the engine control module to control the engine to operate in association with the target engine speed.

Description

technical field [0001] The present invention relates generally to engine control and, for example, to controlling the speed / power of the engine. Background technique [0002] An engine control module (ECM) controls the engine's power output by sending fuel output to one or more of the engine's fuel injectors. The ECM determines fuel output based on an instantaneous engine speed of the engine and a desired engine speed of the engine. The ECM sets the fuel output in an effort to synchronize the instantaneous engine speed with the desired engine speed. The desired engine speed may be determined using one or more operator inputs (eg, accelerator input, retarder input, transmission setting, speed setting (eg, mechanical speed setting and / or engine speed setting, etc.), etc.). Accordingly, the ECM determines a fuel output that corresponds to the difference between the desired engine speed and the instantaneous engine speed of the engine. [0003] However, the load on the engine...
