摘要： A system includes a first module, a second module, and a third module. The first module determines a first temperature and a first power dissipation value of a thermistor based on a resistance of a first resistor connected in series with the thermistor. The second module, after disconnecting the first resistor and connecting a second resistor in series with the thermistor, determines a second temperature and a second power dissipation value of the thermistor based on a resistance of the second resistor. The third module determines a thermal dissipation factor based on the first and second temperatures and the first and second power dissipation values, and corrects temperature sensed by the thermistor based on the thermal dissipation factor.

摘要： A system for detecting a change in medium sensed by a thermistor comprises a first module that receives a temperature signal from a thermistor and that calculates a first dissipation factor of the thermistor. A second module receives the first dissipation factor of the thermistor and detects at least one of an unexpected medium and a change in medium based on the first dissipation factor.

摘要： A method and apparatus for determining the mass air flow into an internal combustion engine without the use of a mass air flow sensor. Speed density and throttle position methods of estimating mass air flow are combined using a first Kalman filter. In one aspect of the invention, the input throttle position into the throttle position mass air flow estimate is the measured throttle position obtained from the throttle position sensor. In another aspect of the invention, the input throttle position into the throttle position mass air flow estimate is the output of a second Kalman filter, which uses as its inputs the measured throttle position obtained from the throttle position sensor and the desired throttle position obtained from the pedal position sensor.
