Definitions

  • the invention relates to a sensor device, in particular for controlling lighting devices of a motor vehicle according to the preamble of the independent claim.
  • Such a sensor device has become known, for example, from DE 199 33 642.
  • This has a voluminous light guide body made of clear plastic, which is attached to the window of a motor vehicle via a coupling medium.
  • This light guide body forms the light radiation from different
  • Solid angle areas depend on the receiver, which in turn controls the lighting devices via a suitable control device. Since to control the lighting devices, the lighting conditions in
  • the light guide must be arranged on the windshield of the motor vehicle, which limits the driver's field of vision due to the expansion of the sensor device.
  • the sensor device according to the invention with the features of the main claim has the advantage that a diffractive element, which is preferably designed as a hologram, creates a very small and compact sensor device that does not restrict the driver's field of vision and nevertheless optimally controls the peripheral devices.
  • the diffractive element is arranged in the receiver area of a receiver, so that the receiver emits radiation from the
  • the diffractive element in the receiver area of the receiver is designed in such a way that it images radiation from different spatial reception areas onto a single receiver, this results in an optimal response behavior of the sensor device, since the different lighting conditions in different directions around the motor vehicle can be reacted to differently.
  • the receiver has a light-sensitive receiver element and a light guide.
  • the receiver element which typically has a semiconductor structure, can be arranged outside the window of the motor vehicle in such a way that only the diffractive element and the light guide, which do not impair the all-round view from the vehicle, are arranged in the driver's field of vision.
  • the difraktive element on a first area of the ⁇ maps to the receiver in the mounted position, radiation from the forward direction of the vehicle and a second portion which in the mounted position, radiation from an angular range which corresponds approximately to the normal direction of the disc, to the receiver , on the one hand, the overall brightness in the vehicle surroundings can be recorded and still be reacted to dark sections in front of the vehicle, such as tunnel or bridge passages.
  • the diffractive element is designed to be controllable, so that the reception range can be set as a function of control signals. In this way, for example, measurements can be taken alternately in the forward direction and in the normal direction of the pane, and information can be obtained from a number of different reception areas with the aid of a single receiver and a single diffractive element. This results in a more precise control of the peripheral devices, the cost of the sensor device only increasing slightly become. It is particularly advantageous if the diffractive element can be controlled periodically.
  • the difractive element is formed in one piece with a further difractive element of a rain sensor.
  • a compact unit for controlling a windshield wiper device and for controlling lighting devices is available.
  • the aforementioned features can of course also be correspondingly transferred to a rain sensor device.
  • FIG. 1 shows a sensor device according to the invention in a schematic cross-sectional representation
  • FIG. 2 shows a variation of a sensor device according to the invention from FIG. 1.
  • a sensor device in a schematic representation in cross section.
  • the sensor device 10 essentially consists of a diffractive element 12 which is designed as a hologram film.
  • This hologram film 12 is glued to a pane 14, for example the windshield of a motor vehicle, or is fastened in some other way, of course the diffractive element 12 can also be arranged in the pane 14.
  • photosensitive receiving elements 13 are arranged as receivers 16, 18.
  • the diffractive element 12 is divided into a first region 20 and a second region 22 and is formed in such a way that light from the through the
  • Arrow 24 indicated forward direction of the motor vehicle receives and maps on the first receiver 16.
  • an opening cone ⁇ with a width of approximately 20 ° is formed, which detects radiation from the forward direction. Before entering a tunnel, less light radiation is detected here than on the open road.
  • the second region 22 of the diffractive element 12 is designed such that radiation from the normal direction 26, which is perpendicular to the pane 14, is imaged on the second receiver.
  • the reception area is selected so that the ambient brightness above the vehicle is detected.
  • the two recipients. 16, 18 are connected to a control device 28, in which, for example, switching thresholds are stored, when they fall below or exceed them
  • Lighting devices 30 are turned on or off.
  • FIG. 2 shows a variation of the sensor device according to the invention from FIG. 1.
  • the hologram film is stuck on the disc 14 as a diffractive element 12.
  • the receivers 16, 18 have in front of their light-sensitive receiver elements 13 first light guides 32 and second light guides 34 correspondingly connected to the first area 20 and second area 22, which guide the light to the receiver elements 13 which For example, are arranged in the roof of the motor vehicle, outside the window 14 and are therefore not visible to the driver.
  • These receivers 16, 18 are in turn connected to the control device 28, which controls the lighting devices 30.
  • any other peripheral devices 30 can be controlled with the sensor device 10 according to the invention.
  • sunroofs, blinds, convertible tops, heating, ventilation, air conditioning, air recirculation flaps and windshield wipers / washers, but also door locks or central locking are available.
  • the sensor device 10 can also be used to program other devices of the motor vehicle. This can be accomplished, for example, by temporarily arranging a selectively controllable light source on the vehicle in the area of sensor device 10, which light source is controlled via specific light signals that correspond to a coding.
  • the sensor device 10 can also be used as an input port for a motor vehicle, which is particularly advantageous when the motor vehicle is locked. For example, it may make sense to have the motor vehicle opened by the central locking if certain signals are conveyed by the first receiver 16 and / or the second receiver 18.
