ABSTRACT:
A temperature sensing device for a vehicle samples air from an interior passenger compartment to determine passenger compartment temperature by purging air in a region surrounding a temperature sensor, in favor of passenger compartment air. A sensor triggered by door operation allows the purging process to begin before a passenger enters the vehicle and the vehicle's automatic temperature control system is activated. A method of accurately measuring the temperature of air in the passenger compartment of the vehicle involves the steps of sensing that the passenger is about to enter the vehicle purging the air in the region surrounding the sensor and drawing in air from the passenger compartment, and measuring the air at the sensor after the purging step.
