摘要： A method is provided for accommodating the purge vapors from an evaporative emission control system of an automotive vehicle. The method includes a means of learning the flow rate of purge vapors from the fuel tank. The fuel tank model uses the output of a strategic adaption routine to learn the tank vapor flow rate. This flow rate is used to maintain fuel to air control under varying air flow and purge flow conditions especially under return-to-idle situations. As such, the fuel to air ratio at the injectors can be controlled under varying air flow and purge flow conditions to improve drivability and emissions.

摘要： A circuit and method are provided for heating a dual heater oxygen sensor. One resistance element is of relatively low resistance such that the oxygen sensor is heated quickly and the other element is of relatively high resistance such that the oxygen sensor is heated and maintained at an optimal operating temperature. The circuit and associated method turn on a low resistance start heater that is in communication with the oxygen sensor given start-up conditions. Once the oxygen sensor has reached an operating temperature range a high resistance operating temperature heater is turned on and the start heater is turned off.

摘要： A residual ratio factor characterizing the amount of residual exhaust gas left in a selected cylinder at the end of a piston intake stroke is determined from tabular and surface models based on previously gathered dynamometer data from a test vehicle at various engine speeds. The residual ratio factor is then used to calculate the mole fractions of air and residual exhaust gas in the selected cylinder, which, in turn, are used to determine mass airflow at an engine intake port at the end of the intake stroke. The mass airflow can then be used to derive further models for determining an engine operating parameter, such as fuel/air ratio, required for achieving at preselected vehicle operating condition.

摘要： A method is provided for accommodating the purge vapors from an evaporative emission control system of an automotive vehicle. The method includes a purge compensation model to identify the concentration of purge vapor entering the intake manifold of the engine of the automotive vehicle, identifying the source of the vapor as from the vapor collection canister or the fuel tank using a characteristic mapping of maximum concentration as a function of instantaneous flow and accumulated flow through a canister and uses this information to predict variations in vapor concentrations as a function of purge flow. The method also includes a purge control model which uses mode logic to identify an appropriate time to initiate a purge cycle, provides the flow conditions necessary for a learning portion of the purge compensation model and increases purge flow rates after the learning is complete to deplete the contents of the canister. The purge control model also manages the time spent with purge active (learning purge) and purge inactive (learning volumetric efficiency or EGR).

摘要： A method of adapting a linear EGR system is provided to adjust flow rates based on engine roughness. Initially, the level of engine combustion roughness is measured and quantified by a known dynamic crankshaft fuel control methodology. In response, the method adjusts the EGR valve desired position higher or lower based on the measured combustion roughness. For example, if the engine is running "smooth", then more EGR is used. If the engine is running "rough", less EGR is used. As the engine approaches a roughness target, the EGR is stabilized.

摘要： A method for pulse width modulating a resistance element of an oxygen sensor. The method quickly heats the resistance element of the oxygen sensor soon after start of the engine with a relatively high duty cycle yielding wide pulse widths. During a mid oxygen sensor temperature range, the method decreasing the duty cycle and thereby the pulse width modulation. And, upon the oxygen sensor reaching peak operating temperature range, the method decreases the pulse width modulated voltage signal supplied to the oxygen sensor to relatively short duty cycled pulses.

摘要： Systems and methods for monitoring electrified vehicle powertrain propulsive torque and taking remedial action when needed involve continuously monitoring an error between the actual and requested propulsive torques and comparing the error to various threshold values. Error exceeding a particular threshold could be indicative of a malfunction, and the vehicle could be afforded an opportunity to regain equilibrium by temporarily decreasing torque output. When the error continues to exceed the threshold or another threshold, however, further remedial action could be required, such as shutting down the vehicle.
