Preferred embodiments of the invention are given in the dependent claims.
The vision system for a vehicle comprises at least one image capture device, which is sensitive to infrared radiation, intended for capturing an image of an environment of the vehicle and directed rearwardly of the vehicle. The vision system further comprises at least one visual display device for displaying the image. According to the invention the image capture device is arranged at a rear side of a mirror glass of an outside rear view mirror of the vehicle, wherein at least a part of a front side of the mirror glass forms a display of the visual display device.
The vision system forms a driver assistance system for assisting a driver of a vehicle when reversing the vehicle and allows a better visibility under poor visibility conditions like in darkness, rain, snow and fog. Thus, the safety for passengers of the vehicle and the road safety are improved.
Brief Description of the Drawings
The present invention will become more fully understood from the detailed description given hereinbelow and the accompanying drawings which are given by way of illustration only, and thus, are not limitive of the present invention, and wherein: Figure 1 is a perspective view of an interior of a vehicle and Figure 2 is a perspective view of the vehicle shown in figure 1.
Corresponding parts are marked with the same reference symbols in all figures.
Detailed Description of Preferred Embodiments
* Figure 1 shows a perspective view of an interior of a vehicle 1 and figure 2 shows a :" perspective view of the vehicle 1. In the following embodiments of the invention are *** * described on the basis of both figures.
The vehicle 1 comprises a vision system which forms a driver assistance system for assisting a driver of a vehicle when reversing the vehicle 1. In the exemplary embodiment shown in figures 1 and 2 the vision system contains three image capture devices 2, 3, 4, wherein all image capture devices 2, 3, 4 are intended for capturing an image of an environment of the vehicle and directed rearwardly of the vehicle 1. The image capture devices 2, 3, 4 are sensitive to infrared and visible radiation.
A first image capture device 2 is arranged at a rear side of a mirror glass 5.1 inside a housing of a left outside rear view mirror 5 of the vehicle 1. A second image capture device 3 is arranged at a rear side of a mirror glass 6.1 inside a housing of a right outside rear view mirror 6 of the vehicle 1. Both image capture devices 2, 3 are arranged in such a manner that they are invisible for the human eye.
In order to make the mirror glasses 5.1, 6.1 transparent for the image capture devices 2,3, the mirror glasses 5.1, 6.1 are one-way mirrors.
Both image capture devices 2, 3 are connected respectively with one visual display device 7, 8. The visual display devices 7, 8 are intended for displaying the respective captured image of the environment, so that the driver is able to see the rearward environment of the vehicle 1.
Thereby a front side of each mirror glass 5.1, 6.1 forms a display of the visual display device 7, 8, wherein the visual display devices 7, 8 are arranged at the rear side of the mirror glass 5.1 inside the housing of each outside rear view mirror 5, 6 too. The visual display devices 7, 8 are liquid crystal displays (= LCD) or thin film transistor displays (= TFT-displays).
The further image capture device 4 is arranged at a rear area of a roof outside of the vehicle 1 on an antenna. In alternative or additional embodiments (not illustrated) the further image capture device 4 and/or more further image capture devices are arranged 15 at a rear of the vehicle 1, for example at a boot lid or a rear bumper, and/or at a rear area * ...fl * of a roof lining of the vehicle 1 and/or at a rear side of a mirror glass 9.1 of an inside rear view mirror 9. S...
The further image capture device 4 is connected with a further visual display device 10, which is arranged at a rear side of the mirror glass 9,1 inside a housing of the inside rear view mirror 9. Thus, a front side of the mirror glass 9.1 forms a display of the further visual display device 10. The further visual display device lOis a liquid crystal display or a thin film transistor display.
In order to make the mirror glass 9.1 transparent for the further image capture device 4, the mirror glass 9.1 is a one-way mirror.
The activation and deactivation of the vision system is effected automatically depending on visibility conditions, wherein the activation and deactivation of the vision system comprise activation and deactivation of the image capture devices 2, 3, 4 and of the visual display devices 7, 8, 10. The vision system is deactivated under poor visibility conditions like in darkness, rain, snow and fog. Also it is deactivated under conditions with a potential for glare, for example due to vehicles approaching from rear. The visibility conditions maybe detected by the image capture devices 2, 3, 4 themselves, such that no additional detectors are required.
In addition an actuating element 11, for example a switch, is intended for manual activation and deactivation of the vision system. The actuating element 11 is arranged in the interior of the vehicle 1, particularly at an instrument panel 12 of the vehicle 1.
In the deactivated state of the vision system, the visual display devices 7,8, 10 are deactivated and the driver can use the outside rear view mirrors 5, 6 and the inside rear view mirror 9 in the conventional way to capture the rearward environment of the vehicle 1. Consequently in case of any technical problem, for example due to software failure of component failures, the conventional operation of the outside rear view mirrors 5, 6 and the inside rear view mirror 9 will not be affected. * . * * ** * * * **** * 0*** * **. ** * * * . * **
