  • Patent number: 8738256
    Abstract: A method of determining a torque transfer touch point of a clutch within a drive train includes applying a predetermined amount of current to an electric motor such that the electric motor will apply a torque to at least a portion of a clutch. The predetermined amount of current will not rotate a shaft of the motor when the clutch is at least partially engaged. The method also includes initiating disengagement of the clutch, detecting movement of at least a portion of the motor, and recording a clutch parameter that is generally coincident with the detecting movement of a least a portion of the motor.

  • Patent number: 6954693
    Abstract: A system for controlling exhaust emissions produced by an internal combustion engine includes an engine controller having an emission manager configured to produce a base emission level cap command, corresponding to a maximum allowable emission level of the engine, as a function of at least altitude and ambient temperature. The emission manager may also include one or more auxiliary emission control devices (AECDs), and the emission manager is further operable in such cases to determine a maximum allowable emission level associated with each active AECD. A final emission level cap command is determined as a function of the base emission level cap command and the maximum allowable emission level associated with each active AECD. The emission manager is further operable to produce a protection state data structure that includes information relating to the operational status of each AECD.

  • Patent number: 6837227
    Abstract: A system is disclosed for estimating the mass flow of recirculated exhaust gas (EGR) from an exhaust manifold to an intake manifold of an internal combustion engine via an EGR conduit disposed therebetween and a fraction of EGR attributable to a mass of charge flow entering the intake manifold. An engine controller is responsive to current values of various combinations of the engine exhaust temperature (ETE), intake manifold pressure (IMP), differential pressure (?P) across an EGR valve, and EGR valve position (EGRP) to determine an estimate of EGR mass flow. The controller is further operable to estimate EGR fraction as a function of the estimated EGR mass flow value, mass flow of charge entering the intake manifold, and engine speed.

  • Patent number: 6804601
    Abstract: A sensor failure accommodation system includes a control computer receiving a sensor signal corresponding to an engine operating condition, and estimating a value of the engine operating condition as a function of one or more engine operating parameters different than the engine operating condition. The computer is operable to control one or more air handling mechanisms as a function of a final engine operating condition value, and if the sensor producing the engine operating condition signal is error free the final engine operating condition value is the engine operating condition signal. If the sensor producing the engine operating condition signal has failed, the final engine operating condition value is the engine operating condition estimate, and if at least one sensor producing the one or more engine operating parameters has also failed, the final engine operating condition value is a commanded or other definable engine operating condition value.

  • Patent number: 6725847
    Abstract: A system for protecting an internal combustion engine employing cooled recirculated exhaust gas (EGR) from excessive condensation includes an auxiliary emission control device (AECD) operable to determine when engine operating conditions correspond to a condensing condition resulting in condensation of water at the outlet of the EGR cooler and/or within the intake manifold or intake conduit of the engine. When such conditions occur, the AECD is operable to close the EGR valve and monitor engine operating conditions. When engine operating conditions no longer correspond to the condensing condition, control of the EGR valve is restored to an air handling system associated with the engine.

  • Patent number: 6705301
    Abstract: A combustion manager portion of an engine controller is responsive to ambient air density and engine temperature signals to schedule charge flow and EGR fraction commands. The combustion manager includes a data structure determination block operable to select an appropriate engine speed/engine fueling data structure based on air density and engine temperature information as well as on desired emissions level and engine operating state (i.e., steady state or transient) information. Charge flow and EGR fraction determination blocks are, in turn, responsive to current engine speed and engine fueling information to produce compute the EGR fraction and charge flow commands as a function of the selected engine speed/engine fueling data structures.

  • Patent number: 6665606
    Abstract: The present invention provides a distributed engine processing system, which includes a plurality of engines with an electronic engine control module located within each of the engines. The electronic engine control module is in substantially continuous communication with a server, located remotely from the electronic engine control module. There is included in the invention a means of communication between the electronic engine control module and the server. The invention further provides a method for distributing engine processing. The electronic engine control module downloads engine information to a common server, which performs processing and analysis of the downloaded information from each engine and processing and analysis of the information downloaded by all engines. After the processing, the server stores all the information within a memory of the server.
