A camera arrangement for motor vehicles with a camera that is arranged in a vehicle interior behind a window is described. In this arrangement, a transparent additional window is arranged behind and a distance away from the window, at least in the portion of the window viewed by the camera, so that a layer of air is enclosed between the window and the additional window.

Camera arrangement for motor vehicles

The present invention comprises a system and method for protecting the interior of an automobile having at least a power roof or power windows. The method includes a damaging element detection sensor for detecting moisture or airborne particles which may damage the interior of the automobile by contacting the material when the automobile is left unattended with the automobile power roof or power windows in an open or lowered position. The damaging element detection sensor may be one of a moisture or particle sensor which detects airborne moisture or particles and accordingly automatically operates the power windows or power roof without the intervention of the automobile operator. The system evaluates whether the moisture or particles are still contacting the automobile and may return the power roof or power windows to the position they were in prior to the moisture detection. The invention further includes an obstruction sensor for detecting whether an obstruction is impeding the operation of power roof and power windows, and an occupant sensor for determining whether there is an occupant in the automobile who may manually control the power windows and power roof, and operate the power roof and power windows accordingly.

Es wird eine Sensoreinrichtung zur Erfassung der Benetzung einer Scheibe (5), insbesondere einer Kraftfahrzeugscheibe, beschrieben. Die Sensoreinrichtung besteht aus DOLLAR A - mindestens zwei lichtaussendenden Sendern (1, 2), die jeweils uber ein zugeordnetes Lichteinkoppelelement (1A, 2A), welche an die Scheibe (5) angekoppelt sind, die Senderstrahlung in die Scheibe (5) einkoppeln DOLLAR A - mindestens zwei Lichtauskoppelelementen (10A, 20A), welche an die Scheibe (5) angekoppelt sind und die Senderstrahlung auf mindestens zwei den Sendern (1, 2) zugeordneten Empfangern (10, 20) auskoppeln, wobei die Sender (1, 2) und Empfanger (10, 20) durch Projektion auf die Scheibe die Eckpunkte eines Trapezes bilden. DOLLAR A Erfindungsgemas weist die Sensoreinrichtung mindestens einen weiteren Sender (3) mit einem zugeordneten Lichteinkoppelelement (3A) und mindestens einen zu dem zusatzlichen Sender (3) korrespondierenden Empfanger (30) auf, dem ein Lichtauskoppelelement (30A) zugeordnet ist, wobei der Sender (3) und der Empfanger (30A) bei einer Projektion auf die Scheibe (5) auf einer Linie angeordnet sind, die im wesentlichen parallel zur Grundlinie des Trapezes und zumindest teilweise innerhalb des Trapezes verlauft.

Automobile rain sensor including an electromagnetic wave (EW) sender (12), receiver (14) on a measured length and the windscreen which affects wave broadening between the sender and receiver is arranged so that deposit formation on it alters the starting signal detected by the sender and falls on extraneous light barriers (28,30), comprising a synthetic plastic, metal, or ceramic layer permeable towards EW only in the region of the measured length. An Independent claim is included for preparation of the extraneous light barriers, e.g. by injection molding.

Rain sensor, in particular for a vehicle and method for producing it

A light sensor for detecting brightness of an outside of a vehicle includes: a light shielding element on a windshield; a light guiding element in a through hole of the light shielding element; and a light receiving element that receives light from the outside of the vehicle via the light guiding element and the windshield. The light guiding element includes an entrance surface facing the windshield and an output surface facing the light receiving element. The entrance surface receives the light from the outside. The light guiding element transmits and outputs the light from the output surface toward the light receiving element. The entrance surface has a top disposed inside of the through hole.

Die Erfindung betrifft eine Sensoreinrichtung zur Erfassung des Benetzungs- und/oder Verschmutzungsgrades einer an einem Kraftfahrzeug angeordneten Scheibe. Zur Verringerung des Fremdstrahlungsanteils aus der Umgebung sind einzelne optische Fuhrungselemente an einer Wandung eines Gehauses angeformt, die durch ein Blockierelement voneinander getrennt sind. Der Strahlungssender und der Strahlungsempfanger sind als SMD-Bauteile ublicherweise auf einer Schaltungstragerplatte angeordnet. Die so geschaffene Sensoreinrichtung hat einen einfachen und kompakten Aufbau.

Sensoreinrichtung und Verfahren zur Herstellung einer Sensoreinrichtung

A sensor device for detecting the degree of wetting and/or soiling of a pane or windshield arranged in a motor vehicle includes individual radiation guide elements integrally molded onto a wall of a housing to be separated from one another by a blocking element of the wall. This reduces the amount of ambient radiation from the environment. A radiation emitter and a radiation receiver are structured as SMD components which are arranged on a circuit board carrier. The sensor device created in this way has a simple and compact design.

The device has a photoelectric light sensor (2) with defined spectral sensitivity for measuring ambient light and connected to a control circuit. The light sensor is only sensitive in a narrow spectral range of 400 to 525 nm and is essentially directed vertically upwards. It has a measurement cone with an aperture angle of up to 60 degrees. Independent claims are also included for the following: a method of switching driving lights depending on the spectral composition of ambient light.
