Definitions
- the invention relates to a composite pane, a method for detecting a state information of a control system and a use of the composite pane in a motor vehicle.
- Modern motor vehicles are increasingly being equipped with additional functionalities.
- Motor vehicles with driver assistance systems are also offered to increase safety in traffic, giving vehicle drivers important information about their current traffic situation.
- systems are known which show information in the field of vision of the driver, where he does not have to look away from the traffic to perceive the information.
- windshields of vehicles which are used, from two glass sheets, which are laminated together via a thermoplastic film.
- the glass sheets are arranged at an angle to each other using a non-constant thickness thermoplastic film.
- Laminated glasses with wedge foils are known for example from EP1880243A2.
- Such windshields may have other components such as rearview mirrors, buttons and sensors in the middle, upper section.
- Such a equipped windshield may have the problem that the view of the driver is restricted by the components.
- the view of the driver on the traffic lights can be considerably complicated by the arranged at the top of components.
- Even a low sun can unreasonably dazzle the driver when looking at the traffic lights. This leads to an unwanted and painful body posture of the driver when he wants to keep the traffic lights in view.
- the invention has for its object to provide a composite pane, in which a driver can perceive the state information of a traffic light in a comfortable Köperiens.
- the object of the present invention is achieved by a composite pane according to claim 1. Preferred embodiments will become apparent from the dependent claims.
- the composite pane according to the invention for a motor vehicle has an outer pane and an inner pane, which are connected to one another via a thermoplastic intermediate layer.
- the composite panel also includes a display device for displaying optical state information to a vehicle operator having at least one light source that emits light to generate optical state information, wherein
- the composite disk is provided for connection to a receiving device for the wireless reception of status information of a control system
- the light source is provided for reproducing the state information of the control system and is arranged at least partially in the intermediate layer in the composite pane between outer pane and inner pane.
- the light source By arranging the light source in the composite pane between outer pane and inner pane in the intermediate layer, the light source can be easily integrated into a production process of the composite pane.
- the receiving device receives status information of the control system, in particular a traffic light, wirelessly.
- the light source is arranged in the composite pane between the outer pane and an inner pane in the intermediate layer and is provided for reproducing the state information of the control system.

- the intermediate layer may preferably be thermoplastic and, after lamination, bond the inner pane, the outer pane and any further intermediate layers to one another. For the purposes of the invention, the lamination is thus the joining of inner pane, intermediate layer and outer pane.
- the production of the composite pane by lamination takes place with, for example, vacuum bag methods, vacuum ring methods, calendering methods, vacuum laminators, autoclave methods or combinations thereof.
- the connection between outer pane and inner pane is usually carried out under the action of heat, vacuum and / or pressure.

- the composite pane or the inner pane and the outer pane are preferably transparent, in particular for the use of the pane as a windshield of a vehicle or other uses in which a high light transmission is desired.
- a disc having a transmission in the visible spectral range of greater than 70% As transparent in the context of the invention is then understood a disc having a transmission in the visible spectral range of greater than 70%. For discs that are not in the traffic-related field of view of the driver, for example, for roof windows, but the transmission can also be much less, for example, greater than 5%.
- the outer pane and the inner pane preferably have a constant thickness with essentially plane-parallel main surfaces and a peripheral side edge connecting them.
- the thickness of the inner pane is in an advantageous embodiment of 0.4 mm to 3.5 mm, preferably from 0.9 mm to 2.1 mm.

- the outer pane, the inner pane and the thermoplastic intermediate layer can be clear and colorless, but also tinted or colored.
- the total transmission through the composite pane in a preferred embodiment is greater than 70%, especially if the composite pane is a windshield.
- the term total transmission refers to the procedure defined by ECE-R 43, Annex 3, ⁇ 9.1 for testing the light transmission of vehicle windows.
- the composite panel is preferably bent in one or more directions of the space, as is conventional for automotive windows, with typical radii of curvature ranging from about 10 cm to about 40 m.
- the composite pane can also be flat, for example, if it is intended as a disc for buses, trains or tractors.
- the wedge angle of the intermediate layer can be constant in the vertical course, resulting in a linear change in thickness of the intermediate layer, wherein the thickness is typically larger from bottom to top.
- the direction "from bottom to top” designates the direction from bottom edge to top edge, ie the vertical curve, but there may also be more complex thickness profiles in which the wedge angle is variable from bottom to top (that is location-dependent in the vertical course), linear or non-linear.
- the thickness of the intermediate layer increases in the vertical course from bottom to top at least in sections.
- the thickness of the intermediate layer may be constant in horizontal sections (that is to say sections approximately parallel to the top edge and bottom edge). Then the thickness profile across the width of the composite disc is constant. The thickness can also be variable in horizontal sections. Then the thickness is variable not only in the vertical but also in the horizontal course.
- the intermediate layer is formed by at least one thermoplastic film.
- the wedge angle can be produced by suitable extrusion of the film or by stretching a film with a constant thickness in the initial state.
- the intermediate layer may be formed by a single film or by more than one film. In the latter case, at least one of the films must be formed with the wedge angle.
- the intermediate layer can also be formed from a so-called acoustic film, which has a noise-damping effect. Such films typically consist of at least three layers, the middle layer having a higher plasticity or elasticity than the surrounding outer layers, for example due to a higher proportion of plasticizers.
- the intermediate layer preferably has a minimum thickness of 0.4 mm to 1, 5 mm, more preferably from 0.5 mm to 1, 0 mm.
- Minimum thickness refers to the thickness at the thinnest point of the intermediate layer, typically the thickness at the bottom edge of the composite disk. Laminated discs with thinner intermediate layers often have too low a stability to be used as a vehicle window can.
- Another aspect of the invention comprises a method for detecting status information of a control system, in particular a traffic light, wherein
- a receiving device of a motor vehicle a state information of
- Control system detected by means of a light-optical signal or radio signal and forwards to a control unit
- the status information is received by a control unit of the motor vehicle and a control signal for the reproduction of the status information is sent to a light source, wherein the light source in the composite pane between a
- Outer pane and an inner pane is disposed in an intermediate layer of the composite pane
- While the speed of the power train is less than or equal to one
- the status information is repeatedly requested by the control unit.
- the status information is repeatedly requested by the control unit, as long as the motor vehicle is at a standstill. If the status information changes, the change is detected by the control unit and a changed control signal is transmitted to the light source.
- the changed control signal has the consequence that the light source of the display device indicates a changed optical state information to the driver.
- the invention also includes the use of a composite pane in a motor vehicle, preferably a passenger car, as a windshield or side window.
