Abstract
A vehicle includes a vehicle system, an outside air temperature (OAT) sensor, a clock, and a controller. The controller includes recorded garage temperatures and actual OAT profiles. At the key-on event, a controller-executed method includes recording an initial temperature reading from the OAT sensor and corresponding time of day from the clock. The controller determines whether the vehicle is in a garage using the profile of recorded temperatures and the time of day, and estimates an OAT for the corresponding time of day when the vehicle is in the garage. An operation of the vehicle system is controlled using the estimated OAT before the vehicle leaves the garage. The system may be a navigation system, and the operation may be modification of a calculated electric vehicle range. The system may be an HVAC or other system in another embodiment.
