METHOD FOR SENSOR THRESHOLD COMPENSATION
First Claim
1. A method for processing, in a signal processing unit, a signal representative of an outside air temperature to be displayed to a driver of a vehicle, comprising the steps of:
- providing the signal processing unit with a first instance of an outside air temperature;
providing the signal processing unit with a first instance of powertrain operating information;
determining a vehicle operating condition requiring alteration of the signal representative of an outside air temperature to be displayed;
providing the signal processing unit with a second instance of the outside air temperature in response to determining the vehicle operating condition requiring alteration of the signal representative of the outside air temperature to be displayed; and
displaying the second instance of the outside air temperature to the driver of the vehicle.

Abstract
A system and method for outputting outside air temperature information and signaling apparatus configured for outputting powertrain operating information, the system comprising instructions causing the at least one data processing device to determine a first instance of signal strength calibration for the ultrasonic sensor based on a last known instance of outside air temperature and a first instance of powertrain operating information, instructions causing the at least one data processing device to determine a vehicle operating condition requiring alteration of the signal strength calibration for the ultrasonic sensor, instructions for altering the signal strength calibration for the ultrasonic sensor and instructions for altering an outside air temperature to be displayed to a driver of the vehicle.

10. A method for processing, in a signal processing unit, a signal representative of an outside air temperature to be displayed to a driver of a vehicle, comprising the steps of:
-
receiving a first instance of an outside air temperature; setting a signal strength calibration and displaying an outside air temperature based on the first instance of the outside air temperature; receiving a vehicle road speed signal; receiving a second instance of outside air temperature receiving a first instance of powertrain operating information; determining when a first vehicle speed condition has been met; setting the signal strength calibration and displaying an outside air temperature based on the second instance of the outside air temperature when the first vehicle speed condition has been met; when the first vehicle speed condition has not been met, determining when a second vehicle speed condition has been met; comparing the first instance of powertrain operating information to a predetermined threshold value; determining when the first instance of powertrain operating information exceeds the predetermined threshold value, displaying the first instance of the outside air temperature; determining when the first instance of powertrain operating information is at or below the predetermined threshold value, displaying the second instance of outside air temperature; comparing the second instance of outside air temperature to the first instance of outside air temperature; and setting the signal strength calibration and displaying an outside air temperature based on the second instance of the outside air temperature when the second vehicle speed condition has been met and the second instance of outside air temperature is less than the first instance of outside air temperature. - View Dependent Claims (11, 12, 13, 14, 15, 16)
