Abstract
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.
Claims13
A method for operating a sensor device in a vehicle, in which signals of a sensor, which is designed to register an outside temperature, and data relating to a route lying in front of the vehicle are processed, comprising:
- evaluating the signals as a function of the data relating to the route, such that a smoothing of the signals is changed as a function of the data relating to the route, wherein
- the smoothing of the signals is attenuated if the vehicle enters a section of the route for which the data relating to the route make it possible to infer that the outside temperature is reduced compared to the outside temperature of a preceding section of the route, and/or
- the smoothing of the signals is boosted if the vehicle enters a section of the route for which the data relating to the route make it possible to infer that the outside temperature is raised compared to the outside temperature of the preceding section of the route.
A vehicle comprising:
- a temperature sensor whose signals can be transmitted;
- and
- a control device to receive signals transmitted from the temperature sensor and to, process data relating to a route lying in front of the vehicle, the control device configured to:
- change an evaluation of the signals as a function of the data relating to the route, and
- change smoothing of the signals as a function of the data relating to the route, and, in changing the smoothing of the signals:
- to attenuate the smoothing of the signals if the vehicle enters a section of the route for which the data relating to the route make it possible to infer that an outside temperature is reduced compared to a temperature of a preceding section of the route, and/or to boost the smoothing of the signals if the vehicle enters a section of the route for which the data relating to the route make it possible to infer that an outside temperature is raised compared to a temperature of a preceding section of the route.
