The operating device (), in particular for a vehicle component or generally for a human/machine interface, is provided with at least one pushbutton (), which has a depressible pushbutton element (). In addition, the operating device () has a guide element (), which defines an accommodating area () in which the pushbutton element () is at least partially accommodated and in which the pushbutton element () is guided, and a capacitive proximity sensor () with an electrode () for detecting an object approaching the pushbutton element (), in particular a hand or a finger of a hand. The electrode () is arranged outside the accommodating area () of the guide element ().

Operating device, in particular for a vehicle component

A solar sensor for the detection of the direction of incidence and the intensity of solar radiation comprises a housing () made of a plastic material that is permeable to at least some of the solar radiation, the housing () having a curved side () facing the incident solar radiation and the housing () optically acting as a lens and having an internal focal plane () defined by the lens characteristics thereof. At least two photosensors () are embedded in the plastic material of the housing (), each photosensor () having a sensor area () sensitive to at least the part of the radiation to which the plastic material is permeable, and the sensor areas () of the photosensors () being arranged in a substantially common plane () located in front of or behind the focal plane (), seen from side () facing the incident solar radiation. The direction of incidence of the solar radiation is determinable based on the intensities of the solar radiation received by the sensor areas () of the photosensors ().

The device for detection of the temperature in the interior of a vehicle, particularly for an air-conditioning system of a vehicle, is provided with an interior temperature sensor () arranged in a housing () arranged in or at a wall () adjacent to the interior () of the vehicle and being at least partially adjacent to the interior () of the vehicle, and a radiation sensor () detecting solar radiation leading to the heating of the housing () of the interior temperature sensor (). Further, the device is provided with a compensation temperature sensor () arranged behind the wall () and such that it is thermally decoupled from the interior temperature sensor () and detecting the heat of air and/or assemblies behind the wall (), which leads to a falsification of the measured value of the interior temperature sensor (). The two temperature sensors () and the radiation sensor () are combined in a common assembly.

Device for detection of the temperature in the interior of a vehicle

A device for determining the temperature in the interior of a vehicle includes a temperature sensor for arrangement behind a wall adjacent the interior, and a processing unit receiving the measuring signal from the temperature sensor and outputting an output signal representing the temperature in the interior of the vehicle, and a thermal conductor for sensing the temperature of the air in the interior in the region close to the wall, the thermal conductor being in thermally conductive contact with the temperature sensor and being provided to extend up to or close to the wall or through an opening in the wall.
