Description

The present invention relates to a motor vehicle and a method for producing a transparent surface element, in particular a pane of a motor vehicle.

Vehicles are known from the prior art which are able, for example, to adjust the inside mirror and / or the rearview mirror in such a way that the driver of the vehicle is not blinded by a vehicle traveling behind at night. The DE 10 2010 021 205 A1 discloses in this context a motor vehicle with a mirror which can be moved from a normal state into a dimming state, in which incident light is reflected less strongly than in the normal state, and with an operating element for moving the mirror into the dimming state, with at least two by means of the operating element Dimming states with different degrees of darkening of the mirror can be set. In systems of this type, however, it has been found to be disadvantageous that the sensors, which for example recognize the light of the vehicle traveling behind, are located in or on the interior mirror. Depending on the load on the vehicle, for example when the trunk is fully loaded, the light sensor may not be able to recognize the vehicle traveling behind. The driver is subsequently blinded by the exterior mirrors, which affects driving safety.

It is therefore an object of the present invention to provide a motor vehicle and a method for producing a transparent surface element, in particular a pane for a motor vehicle, which eliminate the aforementioned disadvantages and enable safe driving, regardless of the load condition of the vehicle.

This object is achieved by a motor vehicle according to claim 1 and by a method according to claim 9. Further advantages and features emerge from the subclaims and the description and the attached figures.

According to the invention, a motor vehicle comprises a body, the body having at least one transparent surface element, and comprising at least one sensor element, the sensor element being designed to detect or detect a light source, the motor vehicle having a control unit which is designed to prevent incidence of light or to regulate or control a light distribution in or within the body and wherein the sensor element is integrated in the at least one transparent surface element. In this way, it can advantageously be prevented that any kind of loading condition of the motor vehicle has an effect on the regulation and / or control behavior of the aforementioned control. In particular, it can be ensured, for example, that a following vehicle can be reliably identified, even if the view to the rear is obscured, to which reaction can then be made by dimming the interior mirror and / or the rearview mirror. According to a preferred embodiment, the motor vehicle is a passenger car. In particular, it is a station wagon, or station wagon for short. It is also particularly advantageous that the sensor element is integrated into the surface element, that is to say is preferably embedded in other words. In particular, it is well protected, for example, and is not directly recognizable by an observer.

According to one embodiment, the sensor element is a light sensor, the light sensor being laminated into the at least one transparent surface element.

According to a preferred embodiment, the transparent surface element is a rear window of the motor vehicle, the sensor element or the light sensor being laminated into the rear window. As already mentioned, it is particularly well protected against external influences. In addition, it can be positioned extremely inconspicuously.

According to a preferred embodiment, the sensor element is integrated or laminated into a black printing area of the rear window. The sensor element can thus be completely hidden. The black printing area is provided in particular in the peripheral edge area of the surface element, in particular the rear window. The surface element, in particular the rear window, expediently has one or more heating conductors or heating conductor sections. In particular, the surface element or the transparent surface element is a laminated glass pane which, for example, comprises two layers / panes, the wires for a heater and the sensor element being arranged or arranged between them.

At this point it should be mentioned that other surface elements, for example side windows or the front window of the motor vehicle, can also have a sensor element.

According to one embodiment, the motor vehicle comprises at least one rearview mirror, the control being designed to adjust, in particular dim, the at least one rearview mirror as a function of a signal from the sensor element. The functionality is particularly designed to avoid dazzling the driver.

According to one embodiment, the at least one rearview mirror is a side mirror of the motor vehicle. The motor vehicle expediently has two such side mirrors, both on the driver's side and on the passenger's side.

According to one embodiment, the at least one rearview mirror is an inside mirror. A light or glare sensor can also advantageously or additionally be provided in the interior, as a result of which it can be recognized whether only the side mirrors may have to be adjusted, but not the inside mirror or vice versa. This is possible, in particular, because the surface element with the integrated sensor element can be used to clearly distinguish whether or not light actually enters the vehicle.

According to one embodiment, the controller is designed to change the transparency of the at least one transparent surface element or at least one transparent surface element. It is also expedient to achieve a dimming, or to adjust the incidence of light or light by virtue of the fact that the surface elements can be darkened, at least locally.

• - Anordnen eines Sensorelements, insbesondere eines Lichtsensors, zwischen den beiden Scheibenelementen;
• - Fügen der Scheibenelemente zu einer Verbundglasscheibe.

The invention also relates to a method for producing a transparent surface element, in particular a pane of a motor vehicle, comprising the steps:

• - Providing a first pane element and a second pane element for producing a laminated glass pane;
• - Arranging a sensor element, in particular a light sensor, between the two disc elements;
• - Joining the pane elements to a laminated glass pane.

The transparent surface element or the pane is preferably a laminated glass pane which, for example, has at least two layers or panes, the sensor element, possibly also a plurality of sensor elements, possibly also of different types, being introduced, embedded or between the two layers is or will be laminated. Such a disc expediently also comprises heating elements or heating wires etc.

The advantages and features mentioned in connection with the motor vehicle apply analogously and correspondingly to the method and vice versa and among themselves.

Further advantages and features result from the following description of an embodiment of a motor vehicle with reference to the attached figures.

Show it:

• 1 : a schematic view of a motor vehicle with a sensor element integrated in the rear window;
• 2nd : a schematic view of a rear window with integrated sensor element.

1 shows a schematic representation of a motor vehicle 1 whose direction of travel is to the left. Behind the car 1 there is a light source 50 . The car 1 comprises a plurality of transparent surface elements, in particular windows, 20, with a rear window in the rear area 22 is arranged. It can be seen that in a rear area or in a loading space of the vehicle 1 a large piece of luggage 40 is arranged, which prevents the light source 50 forward, for example up to the area of a rear-view mirror 30th , especially interior mirrors 34 , shine. If a light sensor were now arranged there, it could not detect anything. But is now advantageously in the rear window 22 a sensor element 60 arranged, in particular integrated or laminated, whereby the light source 50 can be detected. A control system, not shown here, can now use the rearview mirror 30th , especially the side mirrors 32 , adjust so that a driver (not shown here) is not dazzled.

2nd now shows in a further schematic representation a top view of a transparent surface element 20 , especially on a rear window 22 . It can be seen that this has a surrounding black printing area 24th having. A sensor element 60 , especially a light sensor 60 , is advantageous in the black printing area 24th arranged, making it completely invisible to the viewer.
