Abstract
The invention relates to a display system for a motor vehicle (11), in which an image detecting device captures an image of the surroundings of the motor vehicle (11), said image is converted into image data by an image generating device (2), and said image data can be represented as a virtual image in the driver's (7) field of vision via a beam deflection unit (5) and a combiner (6) that features variable transmission.
Description
Technical field
The present invention relates to a kind of display system that is used for self-propelled vehicle, in this display system, image around the image acquisition units logging machine motor-car, these images change into graphicinformation by image device, and this graphicinformation can be presented in the visual field of chaufeur as virtual image by beam deflection unit and synthesizer.
Background technology
Current driver assistance system has for chaufeur data is directly recorded essentiality on the automobile windscreen, even thereby when Windshield is provided with (for example Windshield in autotruck or city motor bus) more suddenly, also can realize the acceptable placement of image generating unit in self-propelled vehicle.
Disclose a kind of system by prior art, in this system, infrared camera exists as image acquisition units and is presented at virtually in the visual field of automobile driver by HUD by the image of infrared camera record.Simultaneously, HUD has the synthesizer between chaufeur and Windshield, and this synthesizer is placed on the straight line sight line (Geradeaussicht) of chaufeur.This synthesizer has fixing transmissivity and reflectivity, by this synthesizer, can realize that image shows.
The greatest difficulty that need overcome when showing by HUD is, guarantees the good property of can read of display image under the condition of all external lights that can consider all the time.
Summary of the invention
Therefore, the objective of the invention is to propose a kind of device that starts described type, this device can be realized the good property of can read under the condition of all external lights.
This purpose realizes like this according to the present invention, and promptly synthesizer has variable transmissivity.Guarantee the readability of telltale when any outside brightness reliably based on this variable transmissivity, HUD can designed to be used day run and operation at night thus.
In an embodiment of the present invention, can automatically regulate the transmissivity of synthesizer.
For this purpose, synthesizer has photochromic material, and this photochromic material changes the transmissivity of synthesizer according to brightness.
In another improvement project, synthesizer is made on the basis of LCD.At this, synthesizer is connected with a control convenience of regulating the transmissivity of synthesizer according to outside brightness.Can make the synthesizer deepening by day thus, and provide the possibility of input image data.At night, controlled synthesizer almost is transparent and is used for image projection equally, for example is used for the function of " night vision ".
In another favourable design plan, the transmissivity of synthesizer can manually change.For this purpose, at least one film with fixed transmittance rate is fixed on the synthesizer, and this film can be tightened at least one regional area of synthesizer.
In another improvement project of the present invention, synthesizer is the component part of the sun shield of self-propelled vehicle.At this, the zone of a delimitation of sun shield used as virtual show media can keep sun shield simultaneously as the effect of preventing sunlight and/or swimming-proof device.
Advantageously, synthesizer itself is designed to sun shield.Be reduced in the outside brightness of appreciiable concerning chaufeur in the viewing area by the transmissivity that reduces synthesizer.Simultaneously, this has produced the less light demand that reflection shows.Can be implemented in first thus in the operation in the daytime and to use HUD with less amplification rate and big demonstration.
Description of drawings
The present invention allows a large amount of embodiment.With reference to the accompanying drawings one of them is further described.
Fig. 1: the diagram of HUD,
Fig. 2: the layout of HUD in autotruck,
Fig. 3: the layout of synthesizer.
The specific embodiment
Fig. 1 shows the HUD 1 that uses as usually in self-propelled vehicle.This HUD is made of image device 2, and this image device is by light source 3 and be set directly at the light source front and be made of its telltale that throws light on 4.The image to be shown that is produced by image device 2 is imaged onto on the synthesizer 6 by the mirror 5 that is arranged in the light path.Chaufeur 7 sees through the Windshield 9 of synthesizer 6 and self-propelled vehicle and sees virtual image 10 on light path 8, this virtual image seems to be created in before the Windshield 9.
Figure 2 illustrates such HUD 1 that is installed in the autotruck 11.Except HUD 1, above the chaufeur control position, also be provided with infrared camera 12, the peripheral region before this infrared camera logging machine motor-car 11.For this peripheral region is thrown light on, on the radiator grid 14 of self-propelled vehicle 11, be fixed with infrared illumination device 13.
Movably the synthesizer 6 of glass sheet form is arranged on the position that is generally sun shield generally speaking in self-propelled vehicle 11 and bears the function of this sun shield in this case simultaneously.Chaufeur 7 is observed through synthesizer 6 and is structured in self-propelled vehicle image 10 before virtually.In addition, also have a secondary display device 15 in self-propelled vehicle 11, wherein display equipment 15, HUD 1 and infrared camera 12 all are connected with control convenience 16, in addition, and the demonstration of this control convenience control virtual image 10.
Therefore, infrared camera 12 preferably uses at night with under the atrocious weather condition, thus by virtual image 10 for chaufeur 7 provides information about those streets that can not observe with the naked eyes of chaufeur, improved safety thus greatly.For this purpose, continue to be transferred on the image device 4 of HUD 1 by control convenience 16 by the image of infrared camera 12 record, and the image that produces by image device showing as virtual image 10 like that as described.
Fig. 3 shows synthesizer 6, and this synthesizer is the part of the sun shield 17 of self-propelled vehicle 11.Simultaneously, HUD 1 is fixed on the synthesizer 6 and is arranged on thus on the straight line sight line of chaufeur 7.
Can be implemented in fully first thus in the operation in the daytime and to use HUD with less amplification rate and big demonstration.Can realize deepening effect, the just effect of sun shield 17 in the daytime based on transmissivity control by 16 pairs of synthesizers 6 of control convenience.In addition, also be created in the possibility of the additional view data of input in the daytime certainly.At night, the reformed control by synthesizer 6 makes synthesizer similar transparent and be used for image projection equally.Utilization preferably is controlled at the transmissivity outside the main line of sight scope of chaufeur 7 according to device of the present invention, thereby can satisfy legal provisions, and these legal provisions do not allow the transmissivity in the main line of sight scope of chaufeur 7 to be reduced under definite boundary.
