摘要： The invention provides a control strategy and a control system to control a gas sensor to a target operating temperature. It relies upon both feedback and model-based feedforward control systems to achieve and then maintain the sensor at the target operating temperature. The mechanization includes a gas sensor with a heating element in a feedstream. The control strategy employs a control system for the heating element that is based upon the target operating temperature, the temperature of the heating element, and an effect of the feedstream and mounting structure on the temperature of the sensor. The control strategy enables the control system to optimize the heating of a sensor during warm-up and steady state operations.

摘要： This invention includes selecting a desired pressure for fuel injection in an internal combustion engine. The selection improves control of fuel injection by keeping the fuel in the fuel rail in a liquid state and by keeping the fuel injectors in an operating region where fuel injector fuel flow is less sensitive to changes in fuel injector pulse width.

摘要： An oxygen sensor heater control determines heater activation based on an open-loop control parameter and a correction factor that compensates for part-to-part variability. Following a cold start where the heater temperature can be reliably estimated, the engine controller predicts the resistance of the heating element and heater circuit at the desired operating temperature of the sensor, and computes the correction factor for heater activation based on the predicted resistance values and nominal resistance values. At least one predicted value is stored in non-volatile memory, and used to compute the correction factor following a warm or hot start of the engine.

摘要： A method for detecting steady-state convergence of a signal compares a filtered version of the signal or its derivative to a threshold over a given time interval, and a measure of the signal variability is used to tune the filter behavior. In one implementation, the signal is filtered with a high-pass filter, and the cut-off frequency of the filter is adjusted inversely with respect to the measured variability of the signal. In another implementation, the signal derivative is filtered with a low-pass filter, and the cut-off frequency of the filter is adjusted in proportion to the measured variability of the signal. In each case, the variability of the signal is measured by computing a differential of the signal and then smoothing the differential.

摘要： An improved position control for a solenoid actuated valve, wherein the solenoid is activated based on the combination of a feed-forward component based on a model of the steady state operation of the valve and a closed-loop feedback component that responds to changes in the commanded position and compensates for any inaccuracy in the steady state model. The method involves a valve characterization procedure in which the actual force generated by the solenoid is measured for various combinations of valve position and solenoid current, resulting in a table of coil current in terms of developed force and valve position. In operation, the model is used to estimate the solenoid force required to achieve the commanded valve position under steady state operating conditions, and a controller addresses the table to obtain a feed-forward coil current command as a function of the commanded valve position and the estimated solenoid force. The feed-forward command is combined with a closed-loop feedback coil current command, which in turn, is used to develop a corresponding PWM duty cycle, given the solenoid temperature and the magnitude of the supply voltage.
