摘要

The warning method (300) involves determining snow or ice volume on a roof of a motor vehicle based on a layer thickness of the snow or ice volume and the snow or ice falling from the roof of the motor vehicle, and determining (315) whether the volume exceeds a predetermined threshold. A warning is outputted (320) to a driver of the motor vehicle before departure. Independent claims are included for the following: (1) a computer program product with program code medium for warning a driver of a motor vehicle against unsafe operating conditions in winter conditions; (2) a warning device for warning a driver of a motor vehicle against unsafe operating conditions in winter conditions; and (3) a warning system for warning a driver of a motor vehicle against unsafe operating conditions in winter conditions.
