OUTSIDE AIR TEMPERATURE MEASUREMENT DEVICE AND METHOD

摘要

An outside air temperature measurement device and method for vehicles derives a useable final value of the outside air temperature within seconds of the beginning of vehicle movement by developing a mathematical expression (i.e., model) for the exponential data series while discriminating against thermal noise components existing in the measurement data.

1. A method for measuring outside air temperature comprising the steps of:
measuring temperature values over time; determining a first order exponential decay of the measured values in real time; predicting a final value of the exponential decay series using a mathematical model; and discriminating against thermal noise components existing in the data to arrive at a final temperature value.
