    摘要： A method is presented for correcting estimates of engine output torque and accessory load torque. Engine output torque estimates are corrected when the accessory is disengaged from the engine. Accessory load torque is learned, or corrected, when the accessory is engaged to the engine. In one example, these corrections are made when engine output torque is known to be substantially zero from torque converter speed ratio or from the timing of the overrunning clutch engagement. This information is then used to control engine output torque to improve drive feel and vehicle performance.

    摘要： A method for estimating a temperature of a tip of an exhaust gas oxygen (EGO) sensor used with a heater in an electronic engine control for an engine having an exhaust system wherein the exhaust system includes a variable length exhaust pipe having a short path and a long path for transporting exhaust gas from the engine to the HEGO sensor and an exhaust valve positioned in the exhaust pipe for regulating the flow of exhaust gas between the short path and the long path utilizes control logic to determine whether the exhaust gas is flowing through the short path or the long path, determine a temperature of the unheated HEGO sensor based on the path of flow of the exhaust gas, and determine whether the heater is on. If the heater is not on, an amount of heat applied to the sensor is set to zero. If the heater is on, an increase in the temperature of the HEGO sensor is determined based on an amount of heat applied to the sensor. The control logic then determines the temperature of the heated HEGO sensor based on the temperature of the unheated HEGO sensor and the increase in the temperature.

    摘要： A method and system for adaptive feedforward control of a fuel delivery system provides for adapting a normalized pressure input and a normalized flowrate input to a feedforward voltage look-up table. If low fuel flow and high manifold pressure are detected (104), then the normalized pressure input will be adapted based on a target fuel rail pressure and a pressure multiplier PMUL. If high fuel flow is detected (106), then the normalized flowrate input will be adapted based on a target flowrate and a flowrate multiplier FMUL. The present invention provides adaptive feedforward control without the need for the look-up table to be stored in a keep-alive memory (KAM).

    摘要： A managed fuel air control system is provided that transitions between a closed loop stoichiometric A/F mode and an open loop lean A/F mode of operation. When conditions permit open loop lean operation, the engine A/F is ramped from stoichiometric to the desired lean A/F. Periodically, while operating in the open loop lean mode, the system returns to the closed loop stoichiometric mode to update an open loop correction factor used during the open loop lean mode. The time at stoichiometric is usually limited to the time it takes to correct errors in calibration data that have occurred during open loop operation. During lean operation, the adaptive corrections learned at stoichiometric A/F are applied.
