Description

The invention relates to an arrangement for a head-up display of a vehicle, comprising a steering column of the vehicle with a housing, a display screen of the head-up display and a deflection mirror of the head-up display. The invention further relates to a steering column for a vehicle with a head-up display, a head-up display for a vehicle and a vehicle.

Arrangements of the type mentioned at the beginning are part of the prior art in various configurations and are used to arrange a head-up display of a vehicle relative to a steering column of the vehicle. The head-up display includes a display screen for displaying display content, at least one and usually several deflection mirrors, generally a plurality of optical elements defining a beam path, and a windshield of the vehicle. The display screen and the deflection mirrors can be referred to as a head-up display unit.

When an occupant of the vehicle looks through the windshield, he or she sees display content displayed by the display screen as a virtual image reflected from the windshield and located outside the vehicle behind the windshield.

The head-up display unit is usually hidden in an instrument panel, i.e. H. a cockpit interior paneling of the vehicle. Several technical tasks have to be solved. First, the display screen generates a large amount of heat loss during normal operation of the head-up display unit. The large amount of heat loss must be dissipated to avoid damage to the display screen due to overheating.

So revealed DE 10 2007 012 905 A1 an arrangement for a head-up display of a vehicle, in which a head-up display unit of the head-up display is arranged above a heat-dissipating support structure of the vehicle and is thermally coupled to the heat-dissipating support structure. Relative to a z-direction of the vehicle, the head-up display unit is arranged above the support structure and a steering column of the vehicle is arranged below the support structure.

Furthermore, occupants of the vehicle may have different body sizes or prefer different seating positions, which inevitably goes hand in hand with different positions of the virtual image of the display content relative to the windshield.

To set a position of the virtual image of the display content DE 10 2012 212 089 A1 an arrangement for a head-up display of a vehicle, in which a head-up display unit is mounted displaceably along a contour relative to a windshield of the vehicle. The contour can extend parallel to a steering column of the vehicle.

The head-up display unit generally has a considerable spatial extent due to the length of the beam path. The spatial extent of the head-up display unit requires a corresponding installation space.

DE 10 2018 116 025 A1 discloses an arrangement for a head-up display of a vehicle, in which the head-up display unit is mounted on a cross member of the vehicle. The cross member is arranged below a steering column of the vehicle in relation to a z-direction of the vehicle.

Thanks to the low-lying cross member, there is more space above the cross member to install the head-up display unit. However, the arrangement of the head-up display is limited by the steering column, which is also located above the cross member. Apart from that, in many cases the instrument panel has to be shaped depending on the space required by the head-up display unit, which is undesirable for aesthetic reasons.

It is therefore an object of the invention to provide an arrangement for a head-up display of a vehicle, which reduces a spatial restriction caused by a steering column of the vehicle and increases freedom in shaping an instrument panel of the vehicle. Further objects of the invention are to provide a steering column for a vehicle with a head-up display, a head-up display for a vehicle and a vehicle.

One object of the invention is an arrangement for a head-up display of a vehicle, comprising a steering column of the vehicle with a housing, a display screen of the head-up display and a deflection mirror of the head-up display. Every vehicle with a head-up display includes a steering column with a housing, i.e. H. a steering column cover, and a head-up display unit, which are arranged relative to each other. Accordingly, they result in a wide range of possible applications for the invention. Furthermore, every vehicle includes an instrument panel in which the head-up display unit is arranged as invisibly as possible for the vehicle's occupants.

According to the invention, the display screen and the deflection mirror are arranged within the housing. Accordingly, the display screen and the deflection mirror do not require any installation space outside the steering column, which is accompanied by a reduced space requirement for the head-up display unit in the instrument panel. In other words, the head-up display unit is partially arranged within the housing of the steering column and is therefore hidden in the steering column.

Thanks to an elongated shape of the housing of the steering column, a relatively large part of the beam path of the head-up display unit, namely the beam path from the display screen to the deflection mirror, can extend within the housing of the steering column. Only the remaining part of the head-up display unit, or the beam path up to the windshield, is arranged in the instrument panel, which increases freedom in shaping the instrument panel. A spatial conflict between the remaining part of the head-up display unit and the steering column is also reduced.

Preferably, the display screen is fixed relative to the housing and the deflection mirror is mounted so that it can pivot relative to the display screen. Thanks to the pivotable mounting of the deflection mirror, the steering column can be pivoted optionally, i.e. H. Setting an angle of inclination of the steering column relative to the vehicle can be compensated for in such a way that the part of the beam path extending in the instrument panel is at each set angle of inclination, i.e. H. every angle position, the steering column is practically identical. In other words, the beam path of the head-up display unit outside the steering column is independent of the angular position of the steering column. In this way, compatibility is achieved between pivoting the steering column and correct functioning of the head-up display.

The arrangement advantageously includes an adjusting mechanism which adjusts a pivot angle of the deflection mirror depending on an angular position of the steering column. The adjusting mechanism can include a gear and couple a pivot angle of the deflection mirror directly to an angular position of the steering column by means of the gear. Alternatively, the adjusting mechanism can include a sensor for detecting an angular position of the steering column, a servomotor for pivoting the deflection mirror and a control device functionally coupled to the sensor and the servomotor, which actuates the servomotor depending on a detected angular position.

The arrangement can include a first further deflection mirror of the head-up display, which is arranged in a recess of an instrument panel of the vehicle. The first additional deflection mirror is the last optical element of the beam path in front of the windshield. Thanks to its arrangement in the recess, the first additional deflection mirror is invisible to the vehicle's occupants. The first further deflection mirror can be mounted adjustably in order to enable a position of the virtual image to be adjusted depending on an occupant's body size or sitting position.

The arrangement can include a second further deflection mirror of the head-up display, which is arranged in the instrument panel of the vehicle. The second further deflection mirror is arranged in relation to the beam path between the deflection mirror arranged in the housing of the steering column and the first further deflection mirror.

The first further deflection mirror and the second further deflection mirror belong to the headup display unit of the headup display. Of course, the head-up display unit can include further deflection mirrors and/or further optical elements.

Ideally, the display screen and the deflection mirror are arranged in opposite end regions of the steering column. In this way, as large a portion of the beam path as possible extends within the housing of the steering column, whereby a remaining portion of the beam path extending outside the housing is shortened.

The display screen and the deflection mirror are advantageously arranged in relation to a z-direction of the vehicle on an upper side of a steering shaft of the vehicle which extends in the housing of the steering column. Thanks to the arrangement of the display screen and the deflection mirror above the steering shaft, the beam path of the head-up display unit does not need to cross the steering shaft.

A second subject of the invention is a steering column for a vehicle with a head-up display.

According to the invention, the steering column is designed as part of an arrangement according to an embodiment of the invention. The steering column houses a display screen and a deflection mirror of a head-up display unit of the head-up display and reduces the installation space required for the head-up display unit outside the steering column.

A third subject of the invention is a head-up display for a vehicle, comprising a Vehicle windshield. The head-up display further comprises a head-up display unit with a display screen and at least one deflection mirror or generally optical element.

According to the invention, the head-up display comprises an arrangement according to an embodiment of the invention. Thanks to the arrangement, the head-up display allows great freedom in shaping a vehicle's instrument panel, which is accompanied by an attractive aesthetics of the instrument panel.

A fourth item is a vehicle. Modern vehicles usually include a head-up display.

According to the invention, the vehicle includes a head-up display according to an embodiment of the invention. Thanks to the head-up display, the interior of the vehicle has an attractive aesthetic.

A significant advantage of the arrangement according to the invention is that a spatial restriction of a head-up display unit of a head-up display by a steering column of a vehicle is reduced and freedom in shaping an instrument panel of the vehicle is increased. In this way, aesthetic shaping of the instrument panel is made easier.
