    摘要： A system and method for controlling an engine or machine at a remote unit from a central office, which may be a fixed location, contemplates a transmit/receive interface connected to the computer or microprocessor of the engine or machine controller. This interface is integrated with a communications module that is configured to establish communications with a World Wide Web server on the Internet. A similar system is established at the location of the central office connected to a computer controlled by a fleet owner/operator, for example. The fleet owner can upload machine control data or machine control application software to an intermediate digital file storage maintained by the Web server via the Internet. This data or application software can be accessed and downloaded at any time by the remote operator without any direct interface or communication with the central office. The remote machine controller includes a data entry device that allows the remote operator to issue commands to the Web server to upload or download information, input password or security information for access to the data in intermediate file storage, or leave messages for the central office. The transmit/receive interface at the remote unit includes means for receiving the downloaded information, determining whether the information is application data or application software, and updating the machine controller accordingly. In this manner, either specific data can be downloaded to modify the performance of the controlled machine, or entirely new application software or modified application software can be downloaded directly to the machine controller.

    摘要： A charge limit manager arbitrates between desired EGR system and/or turbocharger behavior and the actual capabilities of EGR system and/or turbocharger control mechanisms under current operating conditions. In one embodiment, the charge limit manager includes three limiter blocks producing offset signals as separate functions of turbocharger compressor outlet temperature, turbocharger speed and pressure differential (&Dgr;P) across an EGR valve. A charge limit selector block is responsive to the offset values produced thereby, and also to commanded values of charge flow and EGR fraction as well as operating values of EGR valve position and &Dgr;P, to limit the charge flow and EGR fraction commands to controllable values. These values are preferably subtracted from actual or estimated values of charge flow and EGR fraction to produce charge flow and EGR fraction error values for use in controlling one or more EGR system and/or turbocharger swallowing capacity/efficiency control mechanisms.

    摘要： 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. The invention also provides a method for adaptation of the engine in response to the analyses by the server and a method for notification of the engine operator of the changes made to the engine or any necessary services that should be performed on the engine.

    摘要： 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.
