Method and device for pre-conditioning vehicles with improved prediction of the risk of icing

摘要

The invention relates to a method for preconditioning a vehicle, for a scheduled departure time, comprising the steps of:- acquiring (101) vehicle location data, - acquiring (102) weather forecast data relating to the location of the vehicle and preceding the time of departure, said data comprising an air temperature outside the vehicle, a relative humidity, a wind speed, an amount of rain, a cloudiness index.- determining (103) an estimate of a temperature of the windshield from the meteorological data acquired, - if the estimated temperature is lower than a predetermined threshold then activation (104) of a de-icing device so that the windshield is not iced over at the scheduled time.
