Description

The invention relates to a vehicle according to the preamble of claim 1.

From the DE 10 2004 019 473 B4 a control unit for an electronic device with a display and with buttons arranged adjacent to the display is known, the buttons in a first lighting state of the buttons displaying functions that can be selected by pressing the buttons and in a second lighting state of the buttons the buttons can be used to select functions that are shown in the adjacent display. The keys are designed as pushbuttons with key caps and have their own lighting sources that are independent of the display, the lighting states of which can be set independently of the central lighting source of the display. A keycap has a light guide that is arranged on a circuit board. A first light source and a second light source are arranged on the circuit board. These are surrounded by the light guide in such a way that the light generated by the light sources is coupled into the light guide. The light sources are designed as light-emitting diodes. The light coupled into the light guide is coupled out in an edge region of the light guide and is therefore visible to a user by forming an edge around a key cover that covers a central key region. If the first and second light sources are operated in a second lighting state, the key appears with edge lighting. There is a third light source within a cover, which is inactive in the second lighting state. A central area of the key appears dark. If a switch is made to a first lighting state, the first and second light sources are deactivated. The edge area appears dark. A diffuser is arranged between the third light source and the key cover, which is made of a non-transparent, dark plastic material, which homogenizes the light emitted by the third light source. Transparent areas are introduced into the key cover in such a way that a symbol representation or a text representation is created for a user in the central key area. The light homogenized by the diffuser emerges from the keycap through these transparent areas, so that displayed information in symbol or text form is visible to the viewer.

Furthermore, from the DE 10 2016 007 478 A1 a steering wheel for a motor vehicle with a steering wheel, with a central steering wheel body, which is connected to the steering wheel via a spoke, and in the area of which the axis of rotation of the steering wheel is arranged, with a light display for the optical visualization of information about a driving state of the motor vehicle in one highly automated or autonomous driving operation, and with controls known. The light display is designed to be integrated into the steering wheel body and includes various sections and light colors for visualizing the information about the driving status of the motor vehicle in a highly automated or autonomous driving operation. Control elements on the steering wheel body have lighting elements to influence the driving condition and can be illuminated in color in a similar color to the visualization of the information about the driving condition using a light display. The controls are arranged on the side next to the light display and are designed in the manner of a pressure rocker. The controls are illuminated by side light sources as lighting elements of the light display. The light display is designed in such a way that it consists of individual discrete light sources, for example color-changing LEDs. The light sources are not arranged in the area in which the light emerges. The light is redirected in the direction of a driver via light guides and a scattering element. Furthermore, a control device is provided which receives data from a control system for autonomous or highly automated driving of the motor vehicle. The electronic control device passes this data on to the light sources or the electronics that control them in order to operate the light display. The electronic control device also controls the lighting of the control elements at the respective ends of the light display.

Further lighting arrangements for vehicles are from the DE 10 2015 008 071 A1 , the DE 10 2016 225 583 A1 , the DE 10 2007 014 871 A1 , DE 42 32 545 A1 and US 2009/0092366 A1 known.

The subsequently published one DE 10 2017 113 662 A1 describes a motor vehicle operating device for an interior of a motor vehicle with a panel and a circuit board. The cover includes a user interface on which a switching symbol to be operated is shown, which can be backlit by a light source. The light source is assigned to a light shaft that leads to the user interface. The light emitted by the light source runs along the light shaft and backlights the switch symbol to be operated.

Furthermore, from the DE 10 2009 042 244 A1 an operating device for a vehicle is known. The operating device includes

• - a sensor carrier plate on which several sensor surfaces are arranged for capacitive detection of an actuation of the operating device by a user,
• - a lighting support plate on which several lighting elements are arranged and which is arranged parallel and spaced from the sensor support plate.

One of the plurality of sensor surfaces comprises a recess, which is arranged in the sensor surface in such a way that light rays from one of the plurality of lighting elements run through the recess.

The invention is based on the object of specifying a vehicle with a lighting arrangement for illuminating keys, which provides visual feedback on the actuation of a key as well as an illustration of a function triggered or controlled by the corresponding key, an improved and intuitive orientation of a user on a keypad and enables the realization of a particularly high-quality surface and simplification of cleaning the surface.

The object is achieved according to the invention with a vehicle which has the features specified in claim 1.

Advantageous embodiments of the invention are the subject of the subclaims.

A vehicle includes at least one lighting arrangement with a plurality of adjacently arranged buttons and with at least one lighting element for a button. The lighting element comprises at least one light guide and at least one light source, which couples light into the light guide, the light guide being set up to illuminate and/or backlight the key at least in sections and/or areas adjoining an outer edge of the key, which respectively are arranged between two immediately adjacent buttons to illuminate and/or backlight. The at least one light source is set up to emit light with different light colors and/or a plurality of light sources are provided which emit light with different light colors, wherein a set light color or set light colors is or are predetermined by a light color setting of a vehicle interior lighting and by a user is/are selectable.

According to the invention, the lighting arrangement is integrated into a center console, with a translucent or transparent cover covering the light guide in the area between the buttons being flush with a surface of the adjacent buttons. The light guide is at least partially designed as a prism.

The lighting arrangement enables keys or their surroundings to be illuminated as well as optical separation of several keys. It is possible to generate a light effect assigned to an actuated button, which serves as confirmation of actuation and/or to illustrate a function triggered or controlled by the corresponding button.

The lighting element enables the light color of an illumination of the button to be adapted to the vehicle interior lighting, for example so-called ambient lighting. This can be done using the Lighting arrangement and the light color generated by the vehicle interior lighting can be harmonized or contrasted. It is also possible to generate various lighting effects when an actuation is carried out, which serves as an actuation confirmation and/or to illustrate a function triggered or controlled by the corresponding button. When using multiple light sources that emit light with different light colors, a variety of color combinations and/or a variety of color combination effects can be realized.

By means of an intelligent control of the lighting arrangement, it is possible that, for example, when a button is pressed, the light guide, for example forming a design element, is illuminated in a predefined color either statically or dynamically. This makes it possible to illuminate and/or backlight and/or surround a key. This means that additional dynamic lighting effects can be achieved on individual keys or around individual keys, even when the ambient lighting is activated or adjustable. For example, when a sport mode is activated using a corresponding button, the light guide can flash dynamically red alternately from left to right. This can also be done with a dimming function, whereby the lighting slowly becomes brighter and darker. The button itself can be static, for example white or in a different light color, or dynamically backlit.

The integration of the lighting arrangement into a center console is made possible by the particularly small size of the lighting arrangement. The illuminated areas of the light guide located between the keys can be used as separating elements between the keys. In addition to the visual feedback about an operation of the corresponding button and the illustration of a function triggered or controlled using the corresponding button, this also enables an improved and intuitive orientation of a user on a keypad on a center console of the vehicle.

The cover enables, on the one hand, protection of the light guide from mechanical and chemical influences as well as contamination and, on the other hand, easy cleaning of a surface of the lighting element. The flush finish of the cover with the surface of the adjacent keys enables the realization of a particularly high-quality surface and simplifies cleaning of the surface.

A variety of light effects can be generated by means of the light guide, which is at least partially designed as a prism.

In a possible embodiment of the vehicle, the at least one light source is designed as a light-emitting diode, for example as a so-called RGB light-emitting diode. Such a light source is characterized by its small size, low energy requirements, easy control and great longevity.

In a possible development of the vehicle, the prism has at least two opposing mirror-symmetrical areas, each area being optically coupled to at least one light source. In this way, the number of light effects that can be generated can be further increased while at the same time having a particularly compact design. In particular, dynamic lighting effects, i.e. H. Lighting effects with an apparent movement of the lighting can be achieved.

For example, the cover is made of glass or plastic so that a particularly high-quality surface can be created.

A further possible embodiment of the vehicle provides that the lighting arrangement is coupled to a light control unit, which is provided for controlling the lighting arrangement and vehicle interior lighting. In this way, control of the lighting arrangement adapted to the vehicle interior lighting, for example the so-called ambient lighting, can be implemented in a simple manner.
