    摘要: The present invention provides a method and apparatus for determining a performance characteristic of at least one of a plurality of fuel injectors located within a fuel system. The method includes the steps of determining a first desired fuel quantity to be delivered by the plurality of injectors, suspending fuel delivery by one of the injectors, determining a second desired fuel quantity to be delivered by the injectors in response to the suspension, and determining a performance characteristic of the suspended injector in response to said first and the second desired fuel quantity.

    摘要: A communications network is adapted to provide communication between control modules on a vehicle. Each control module includes a first and second transceiver. A control module checks for the presence of a data message from another control module before transmitting a data message. If there is no other data message present, the control module transmits the data message around the network in both directions using the first and second transceivers. The other control modules receive the data message from the previous control module and pass the data message to the next control module in the network.

    摘要: The present invention provides apparatuses and methods for filtering a signal. A first processing device receives a first control signal and a first feedback signal and transmits a first error signal as a function of those signals. A second processing device receives the first error signal and transmits a second control signal as a function of the first error signal, a deadband, and a gain factor. A third processing device receives the second control signal and the first feedback signal and transmits an output signal as a function of those signals. A fourth processing device receives the output signal and transmits the first feedback signal as a function of the output signal to the first processing device and the third processing device, the first feedback signal being substantially equal to the output signal delayed by a first predetermined duration of time.

    摘要: The present invention is adapted to provide a method and apparatus for dynamically determining an individualized fuel command for each fuel injector connected to an engine. In the preferred embodiment the method includes delivering a baseline fuel command to each of the injectors. The actual engine speed is then determined. An individualized fuel command is determined for each of the fuel injectors based on the baseline fuel command, and the actual engine speed. In the preferred embodiment the individualized fuel commands are dynamically determined when the engine is idling. In an alternative embodiment, the individualized fuel commands may be used throughout the operating speed range of the engine.

    摘要: An apparatus for controlling a continuously variable transmission is disclosed. The apparatus includes (i) an input shaft driven by an engine, (ii) an output shaft, (iii) an operator input for generating speed commands, and (iv) a controller operable to receive said speed commands and generate transmission ratio commands which control a ratio of a speed of the output shaft to a speed of the input shaft. An upper transmission ratio limit is defined by first engine speed and a lower transmission ratio limit is defined by a second engine speed. When the speed command requires a transmission ratio command greater than the upper transmission ratio limit, the controller adjusts the transmission ratio command to the upper transmission ratio limit, whereas when the speed command requires a transmission ratio command less than the lower transmission ratio limit the controller adjusts the transmission ratio command to the lower transmission ratio limit. A method for controlling a continuously variable transmission is also disclosed.
