Definitions
- the invention relates to a display system for a motor vehicle, in which an image capturing unit bung the image of the other ⁇ of the motor vehicle picks up, which generating means from an image ⁇ into image information is converted to that of a beam deflecting unit and a combiner than vir tuelles image in the field of view Driver is presentable.
- Today's driver assistance systems have the need to load the data directly into the vehicle windshields for the driver in order to realize an acceptable placement of the image forming unit in the vehicle even with a steeply arranged windshield, as for example in a truck or a bus.
- the invention is therefore based on the object to provide an arrangement of the type mentioned, which allows a good readability in all ambient light conditions.
- the object is achieved in that the combiner has a variable transmission. Due to this variable transmission, the readability of the display is guaranteed for every external brightness, which makes the head-up display suitable for both daytime and nighttime operation.
- the transmission of the combiner is automatically adjustable.
- the combiner may comprise photochromic substances which, depending on the brightness, change the trans ⁇ mission of the combiner.
- the combiner is manufactured on the basis of LCD 's.
- the combiner is connected to a, the transmission of the combiner depending on the founded on the founded on the founded on the founded on the founded on the founded on the founded on the founded on the founded on the founded on the founded on the founded on the founded on the founded on the founded on the founded on the founded on the founded on the founded on the founded on the founded on the founded on the founded on the founded on the founded on the founded on the combiner depending on the Jardinhel ⁇ ltechnik adjusting control device. This can be done during the day a darkening of the combiner, and the possibility of Jardin Schemeblendung is given. At night, the controlled combiner would look almost transparent and also for image projection, z. B. for the functionality "Night Vision" serve.
- the transmission of the combiner is manually changeable.
- the combiner is part of a sun visor of the vehicle.
- Use ei ⁇ nes delimited area of the sun visor as a virtual display medium allows at the same time the attitude Aufrechter- the sun visor in its effect as solar and / or anti-glare.
- the combiner itself is designed as a sun visor. By lowering the transmission of the combiner, the outside brightness visible to the driver is reduced in the display area. This results in a low light requirement for theRocpiegelte display. The use of low-magnification head-up displays and large daytime displays is now possible.
- Fig. 3 Arrangement of the combiner.
- Fig. 1 shows a head-up display 1, as it is commonly used in vehicles. It consists of a Bilderzeu ⁇ supply means 2, consisting of an illumination source 3 and, arranged immediately before that and this illuminating display. 4
- the image to be displayed generated by the Bilderzeugungsein ⁇ unit 2 is imaged by a beam path in mirror 5 disposed on a combiner. 6
- the driver 7 sees through the beam path 8 through the combiner 6 and the windshield 9 of the motor vehicle through ⁇ a virtual image 10, which is apparently generated in front of the windshield 9.
- Such a built-in truck 11 head-up display 1 is shown in Figure 2.
- an infrared camera 12 is arranged above the driver's workplace, which generating the environment in front of the motor vehicle 11 receives.
- infrared lights 13 are attached to the grille 14 of the motor vehicle 11.
- the combiner 6 in the form of a movable glass pane is arranged at the position of the otherwise usual sun visor in the motor vehicle 11 and at the same time assumes the function of this sun visor.
- the driver 7 considers the virtually built up in front of the vehicle image 10 by the combiner 6 towards ⁇ through.
- a secondary display device 15 is still present in the vehicle 11, wherein both the display device 15, the head-up display 1 and the infrared camera 12 are connected to a control unit 16, which among other things controls the display of the virtual image 10.
- the infrared camera 12 is preferably used at night or in bad weather conditions to give the driver 7 with the help of the virtual image 10 information about the road, which he himself can not perceive with the naked eye, whereby the security is substantially increased.
- the images taken by the infrared camera 12 are forwarded by the control unit 16 to the image generating device 4 of the head-up display 1, and the image generated by the image generating device is represented as a virtual image 10 as described.
- Fig. 3 shows the combiner 6, which is part of the sun visor 17 of the motor vehicle 11.
- the head-up display 1 is fastened above the combiner 6 and thus placed above the straight line ⁇ outlook of the driver 7.
- the combiner 6 is connected to the control unit 16.
- This control unit 16 controls a function of the outdoor brightness detected keitssensor with a not further shown Hellig ⁇ , the transmission of the combiner 6.
- Hellig ⁇ the transmission of the combiner 6.
- the transmission is preferably controlled outside of the primary viewing area of the driver 7, che to fixturei ⁇ rules which do not allow a reduction in the transmittance in the primary view of the driver (7) below a certain limit, to fulfill.
