A system for controlling an aerodynamic shutter of a vehicle includes an ambient temperature estimation module that determines an ambient temperature. A shutter control module that determines whether to actuate the shutter based on the ambient temperature. The shutter control module also determines a predetermined period before selectively applying a predetermined torque value to the shutter. The predetermined period is selected based on the ambient temperature.

A speech recognition method includes the steps of receiving input speech containing vocabulary, processing the input speech with a grammar to obtain N-best hypotheses and associated parameter values, and determining whether a first-best hypothesis of the N-best hypotheses is confusable with any vocabulary within the grammar. The first-best hypothesis is accepted as recognized speech corresponding to the received input speech if the first-best hypothesis is not determined to be confusable with any vocabulary within the grammar. Where the first-best hypothesis is determined to be confusable, at least one parameter value of the first-best hypothesis can be compared to at least one threshold value, and accepting the second-best as the recognized speech, if its confidence score is within certain lower and upper threshold values and is not confusable with the first-best. The first-best hypothesis can be accepted as recognized speech corresponding to the received input speech, if the parameter value of the first-best hypothesis is greater than the threshold value.

A method of circumstantial speech recognition in a vehicle. A plurality of parameters associated with a plurality of vehicle functions are monitored as an indication of current vehicle circumstances. At least one vehicle function is identified as a candidate for user-intended ASR control based on user interaction with the vehicle. The identified vehicle function is then used to disambiguate between potential commands contained in speech received from the user.

Methods and apparatus are provided for estimating the remaining state-of-charge of a non-rechargeable power source, such as a back-up battery for an electronic module normally connected to a primary power source. A processor within the electronic module implements a prediction algorithm, in order to monitor the temperature of the back-up attery, and to calculate various current draws of the back-up battery. The processor adjusts the nominal self-discharge rate of the back-up battery in accordance with the measured temperatures, and calculates an adjusted self-discharge quantity. The processor also accumulates current draw data and reduces the initial state-of-charge value of the back-up battery by the temperature-adjusted self-discharge quantity and the cumulative current draw quantities to determine a remaining state-of-charge of the back-up battery. At a predetermined state-of-charge threshold level, an indicator can be activated to advise a user to replace the back-up battery.

A method and apparatus are disclosed for testing an airbag restraint system of the type having at least two parallel connected inertia sensors connected in series with a squib across a source of electrical energy, each inertia sensor having a normally open switch and an associated parallel connected resistor. Each parallel connected inertia sensor has a series connected diode for isolating its associated inertia sensor circuit from other circuit components in the firing circuit. A microcontroller monitors at least one voltage value at a component connection while at least one parallel connected inertia sensor is isolated. The microcontroller determines a value functionally related to the resistance of at least one circuit component in the firing circuit while at least one parallel connected inertia sensor is isolated. The microcontroller compares the determined value against predetermined limits. If the determined value is not within the predetermined limits, an error indication is provided.

A test circuit for an airbag restraint system is disclosed and provides an accurate determination of the operativeness of a storage capacitor and calculates the resistance of inertia switch resistors. The capacitor is tested by discharging and charging the capacitor. The values of the inertia switch resistors are determined by switching known resistive values in parallel with the inertia switch resistors. Based on the monitored voltage values during the switching, resistance values are calculated.
