Abstract: A method and apparatus using a programmed processor for electronic circuit simulation in which raw data containing both independent and dependent variables is acquired. That raw data is analyzed using an analysis method which generates relationships between the independent and the dependent variables. A mathematical model is created from those relationships and this is repeated for at least two different analysis methods. The statistical error between the raw data and the computed dependent variables is then calculated and the analysis method having the smallest statistical error with sufficient sample size is selected.

Abstract: A high pressure fuel pump for use with a direct injection engine having a housing which defines a pump chamber. A port is formed in the housing which fluidly connects a fuel in the passageway with the pump chamber. An elongated valve is movably mounted within the housing between an open and a closed position. In its open position, the inlet passageway is fluidly connected with the pump chamber while, conversely, in the closed position the fuel valve blocks the fluid flow between the inlet passageway and the pump chamber. A circuit controls the deceleration of the valve to reduce pump noise.

Abstract: A method and apparatus for developing microcomputer-based systems. A controller model having at least one parameter is simulated and, similarly, a plant model having at least one parameter and controlled by the controller model is simulated. A user interface then has access to the parameters of the controller model and plant model and optionally suspends the execution of the controller model and plant model in response to a trigger event. The user interface determines the status of the controller model parameters and/or plant model parameters at the time of the trigger without altering the controller model parameters or plant model parameters or the program code of the controller model.

Abstract: A noise reduction system for an automotive vehicle powered at least in part by an electric motor located separately from the passenger compartment. The system includes at least one sensor which produces an output signal having a frequency, amplitude and phase representative of noise generated by the electric motor. At least one speaker is positioned closely adjacent the electric motor. A speaker output controller receives the output from the sensor as an input signal and generates an output signal to the speaker so that the speaker produces an audible signal having substantially the same frequency and amplitude but inverted in phase relative to the output from the sensor.

Abstract: A fuel pump for a direct injection internal combustion engine having a body with a valve seat. The valve includes a valve head and the valve is movably mounted to the body between an open position and a closed position. In its open position, the valve head is spaced from the valve seat white in its closed position, the valve head abuts against the valve seat and closes the valve. An electric coil upon energization moves the valve to an open position and, conversely, upon deenergization allows the valve to move to a closed position. A control circuit controls the energization of the coil to reduce the pump noise during operation of the engine, especially at low speeds.

Abstract: A method to reduce engine noise in a multi-cylinder direct injection internal combustion engine. The internal combustion engine includes a high pressure fuel pump having both an inlet valve fluidly connected to a fuel source and an outlet valve typically connected to a pressurized fuel rail. In order to reduce engine noise, especially at low engine speeds, the timing of the opening of either the fuel pump inlet valve or fuel pump outlet valve is varied so that it coincides with the opening of the fuel injectors.

Abstract: A method for the co-simulation of two or more interacting mathematical models in which each model has at least one input port and one output port for inputting and outputting values of parameters in a predefined parameter protocol. The unit of measurement is identified for each parameter in the model and a scaling factor is then generated to equalize the units of measurement for each parameter in each model. The parameter protocol for each port is then determined and a virtual bus with unique locations is configured for each parameter in the models. The parameters from the models are then configured as a function of the parameter protocol so that the same parameters from different models are associated with the same location in the virtual bus.
