Abstract:
1. A temperature sensing system for movable vehicles, the system comprising: a temperature sensor configured to mount to a vehicle to measure a temperature of air defining an ambient temperature; a controller operably connected to the temperature sensor and obtaining a plurality of temperature readings from the temperature sensor at distinctly different times; wherein a rate of change of the temperature of the readings from the temperature sensor when the temperature sensor is exposed to air at an ambient temperature is generally equal to a time factor multiplied by a difference between a temperature reading of the temperature sensor at a plurality of selected times and an ambient temperature at the selected times such that a difference between the temperature readings and an ambient temperature is reduced over time until the temperature readings are about equal to the ambient temperature; and wherein: the controller utilizes predefined data concerning the time factor to estimate the ambient temperature utilizing a plurality of temperature readings taken at selected times at which there is a significant difference between at least some of the temperature readings.
