摘要： A powertrain control method for an internal combustion engine responsive to an accelerator pedal input, the engine having a throttle responsive to a commanded throttle position. The method comprises the steps of determining the engine speed, determining the accelerator pedal position, and generating a desired throttle position value as a function of at least the accelerator pedal position and engine speed. If the commanded throttle position is greater than the desired throttle position value, the commanded throttle position is limited to the desired value.

摘要： A powertrain control method for an internal combustion engine responsive to an accelerator pedal input, the engine having at least one fuel injector responsive to a commanded fuel signal. The method comprises the steps of determining the engine speed, determining the accelerator pedal position, and generating a desired fuel quantity value as a function of the accelerator pedal position and engine speed. If the commanded fuel signal is greater than the desired fuel quantity value, the commanded fuel signal is limited to the desired value.

摘要： A powertrain control method for an internal combustion engine having a throttle responsive to a throttle position command. The method comprises the steps of determining the engine speed, determining the actual throttle position, and generating a desired throttle position value. In one aspect of the invention, the desired throttle position value is generated as a function of the actual throttle position and engine speed. In particular, the throttle position divided by the engine speed can be resolved to a single constant. As such, a simplified powertrain control monitor can be obtained by comparing the throttle position divided by engine speed to a predetermined constant. If the throttle position is greater than the desired throttle position value, the commanded throttle position is limited to the desired value.

摘要： A method for controlling the air/fuel ratio of an internal combustion engine uses a manifold pressure sensor and an exhaust gas recirculation system having an orifice and a exhaust pressure sensor located upstream of the orifice. Both the manifold pressure sensor and the exhaust pressure sensor are sampled synchronously with a frequency proportional to the firing frequency of the engine and then filtered to eliminate unwanted frequencies. The sampled signals obtained then have the necessary bandwidth needed for closed loop control of the exhaust gas recirculation flow and engine air/fuel ratio control.

摘要： A fuel control method uses a MAP sensor output that is encoded to render fueling computations insensitive to microprocessor clock accuracy. The signal output of the MAP sensor is encoded as a pulse width modulated signal, the cylinder air mass is calculated as a function of the encoded MAP signal and the engine is fueled according to the calculated cylinder air mass. By using the same time scale to decode the pulse width of the MAP PWM signal as is used to time injector duration, the time scale becomes irrelevant to the actual fuel/air ratio attained.
