Identifying position of a first rotating shaft may comprise a first position detection system and a second position detection system. A controller may be coupled to a first sensor and a second sensor and may identify the position of the first shaft using the identified shaft position from either the first detection system or the second detection system, whichever is identified faster. The first shaft may have a first wheel disposed thereon with targets and one or more gaps disposed about the first wheel. A second shaft may have a second wheel disposed thereon with targets and one or more gaps disposed thereon. The second wheel is in a fixed relationship relative to the first wheel. The first detection system may use data simultaneously from the first sensor and the second sensor to eliminate targets to determine position. The second detection system uses data only from the first sensor.

Method for determining rotational position of a rotating camshaft on a reciprocating engine using a target with a pattern of teeth and a collection of detection algorithms

A work vehicle including an engine, configured to supply power for driving a ground engaging traction device, and a hybrid power system to drive a powertrain. An engine controller is operatively coupled to the engine and is configured to generate a hybrid torque command received by a hybrid powertrain controller operatively coupled to the engine controller. The hybrid powertrain controller is configured to generate an available hybrid torque signal and a desired hybrid torque signal both of which are configured to be received by the engine controller. The engine controller generates an engine command signal configured to command the engine to operate at a commanded engine torque, in response to the available hybrid torque signal and the desired hybrid torque signal.

Combined engine and hybrid power system load control

A system for detecting individual cylinder misfire in a multiple cylinder internal combustion (IC) engine having exhaust gas recirculation (EGR). The system includes: a device for predicting EGR flow rate on a cylinder to cylinder basis; a device for sensing actual EGR flow rate on a cylinder to cylinder basis with all cylinders firing; and a device for comparing the predicted EGR flow rate to the actual EGR flow to determine individual cylinder misfire.

A method for optimizing fuel consumption in a machine powered by an internal combustion engine includes providing a fuel economy map associated at least in part with the internal combustion engine, the fuel economy map defining a fuel economy at a plurality of operating points of the internal combustion engine; determining a reserve need associated with the machine; determining an available reserve of the internal combustion engine for the plurality of operating points; identifying each operating point of the plurality of operating points having an acceptable reserve, the acceptable reserve being the available reserve that satisfies the reserve need; evaluating the fuel economy for the each operating point; and defining an output value for the each operating point based on the fuel economy and the acceptable reserve.
