A method operates a sensor device in a vehicle. In the method, signals from at least a sensor designed to register an outside temperature are processed. In addition, data that relates to a track located in front of the vehicle is processed. An evaluation of the signals is changed as a function of the data relating to the track. Herewith, it is possible to quickly display an abrupt fall in temperature, such as can be the case when travelling out of a tunnel, on a display belonging to the vehicle and to thus warn the driver of the vehicle in time. A vehicle has a control device that is designed to process signals from a temperature sensor and data that relates to the track located in front of the vehicle.
