Method for determining ambient air temperature outside of a vehicle
Abstract:
A method for determining ambient air temperature outside of a vehicle with a sensor mounted on the vehicle, includes the steps of determining a road speed of the vehicle, comparing the determined road speed to a reference road speed value, if the determined road speed is below the reference road speed value, activating a device to move ambient air across the sensor, the ambient air being drawn from a location outside the vehicle, taking a temperature reading with the sensor, and, if the temperature reading is lower than a stored temperature value, storing the lower temperature reading as the ambient air temperature.
