摘要： A system and method for controlling a powertrain including an automatic transmission include determining a value representing requested powertrain output, determining a rotational speed representing current operating conditions, generating a command to initiate a ratio change in the automatic transmission, and determining a dynamic pressure for the automatic transmission during the ratio change based on the requested powertrain output and the rotational speed. The requested powertrain output may be a wheel torque determined in part by accelerator pedal position. A performance adder based on requested wheel torque may be provided to further enhance operation.

摘要： A system and method for controlling a vehicular powertrain including an internal combustion engine, an automatic transmission having a plurality of selectable gear ratios, and a controller in communication with the internal combustion engine, the transmission, and an accelerator pedal, include determining a driver requested wheel torque based on position of the accelerator pedal, and determining a vehicle speed ratio changing threshold based on the driver requested wheel torque. In one embodiment, the system and method determine a value indicative of current barometric pressure, determine a current gear ratio, and modify the driver requested wheel torque based on the current barometric pressure and the current gear ratio to determine a compensated wheel torque. The compensated wheel torque is used to determining the ratio changing threshold. Offset values are included to adjust for barometric pressure variation, transmission oil temperature, and to prevent gear hunting or excessive ratio changing.

摘要： A misfire monitoring method and system employ an indicated mean effective pressure (IMEP) parameter for misfire monitoring of an internal combustion engine of a vehicle. The method and system include determining displacement and torque of the engine. An indicated mean effective pressure (IMEP) parameter is then calculated for the engine. The indicated mean effective pressure (IMEP) parameter is engine torque divided by engine displacement. A misfire monitor monitors the indicated mean effective pressure (IMEP) parameter to detect misfire. The method and system include determining maximum indicated mean effective pressure (IMEP_MAX) parameter for the engine. A normalized indicated mean effective pressure (IMEP_LOAD) parameter for the engine is then calculated. The normalized indicated mean effective pressure (IMEP_LOAD) parameter is the indicated mean effective pressure (IMEP) parameter divided by the maximum indicated mean effective pressure (IMEP_MAX) parameter. Monitoring the indicated mean effective pressure (IMEP) parameter to detect misfire includes monitoring the normalized indicated mean effective pressure (IMEP_LOAD) parameter to detect misfire.

摘要： A system and method for controlling an internal combustion engine to improve air/fuel ratio control using a feed-forward observer-based control strategy include estimating current and future airflow actuator positions, determining corresponding mass airflow values, and determining a future in-cylinder air charge based on a difference between the current and future mass airflow values. In one embodiment, the difference between current and future mass airflow estimates is used as a feed-forward term and combined with a sensed or measured value generated by a mass airflow sensor prior to being processed using a manifold filling model to predict the future cylinder air charge. In another embodiment, the current and future mass airflow estimates are processed using the manifold filling model with the results used to generate a future delta cylinder air charge that is subsequently used as a feed-forward term and combined with a measured air charge corresponding to a measured mass airflow processed by the manifold filling model.
