Abstract:
A solar sensor for the detection of the direction of incidence and the intensity of solar radiation comprises a housing (12) made of a plastic material that is permeable to at least some of the solar radiation, the housing (12) having a curved side (14) facing the incident solar radiation and the housing (12) optically acting as a lens and having an internal focal plane (26) defined by the lens characteristics thereof. At least two photosensors (16) are embedded in the plastic material of the housing (12), each photosensor (16) having a sensor area (18) sensitive to at least the part of the radiation to which the plastic material is permeable, and the sensor areas (18) of the photosensors (16) being arranged in a substantially common plane (19) located in front of or behind the focal plane (26), seen from side (14) 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 (18) of the photosensors (16).
Abstract:
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 (28) arranged in a housing (18) arranged in or at a wall (12) adjacent to the interior (14) of the vehicle and being at least partially adjacent to the interior (14) of the vehicle, and a radiation sensor (30) detecting solar radiation leading to the heating of the housing (18) of the interior temperature sensor (28). Further, the device is provided with a compensation temperature sensor (36) arranged behind the wall (12) and such that it is thermally decoupled from the interior temperature sensor (28) and detecting the heat of air and/or assemblies behind the wall (12), which leads to a falsification of the measured value of the interior temperature sensor (28). The two temperature sensors (28,36) and the radiation sensor (30) are combined in a common assembly.

Abstract:
The electric heating system, in particular for a hybrid vehicle or electric vehicle, is provided with a heating module. The heating module is provided with an electrically insulating, heat conducting ceramic substrate which has a heating zone and a control zone which are spaced apart from one another. The heating module comprises an electrical resistance heating element which is arranged on the ceramic substrate, in the heating zone thereof, and which is embodied as a resistance heating conductor which is mounted on the ceramic substrate. Further, the heating module comprises a transistor for controlling the current through the resistance heating conductor, wherein the transistor and other optionally present electrical components and conductor tracks are arranged in the control zone on the ceramic substrate. The heating module is provided with a first cooling element which is thermally coupled to the heating zone of the ceramic substrate.
