Abstract

The invention relates to a motor vehicle with means for illuminating traffic signs (4, 5), these being detected by a camera and a headlight (8) being controlled by a control unit in such a way that the signs are illuminated in certain traffic situations.

Description

The invention relates to a motor vehicle with tools to improve the lighting of Road signage elements, as is known from EP 0 465 330 B1 is known. This publication proposes Train vehicle headlights so that they are next to the visible light additionally emit ultraviolet light, which is reflected by traffic signs. It will So basically UV light emitted, which is not only about Signs of interest, but on various counter stands is reflected in the vehicle environment and thus for Drivers cause a variety of light stimuli. These can also be distracting.

Alternatively, it is known from US-A-5,021,715 that traffic signs from stationary facilities be be lit when there are vehicles in the area Signs are located. Such systems have been used in Pra xis not yet implemented.

The object of the invention is a motor vehicle to create the means of lighting street lighting has features that are reliable only for illuminate the motor vehicle currently relevant signs,  without road traffic - especially oncoming vehicles Road users - affect negatively.

To solve this task, he excels Motor vehicle according to the invention by the in the claim 1 specified characteristics. Further details of the Er invention emerge from claims 2 to 10.

Modern motor vehicles are made with cameras be allowed to analyze the lie in front of the vehicle space. The camera data are ba for track finders, obstacle detection systems or Cruise control systems.

It is suggested to take pictures of such a forward facing camera, with regard to in front of Traffic signs located in the vehicle evaluate and the recognized signs by means of a spe to illuminate the headlight. For this the Bil which is analyzed by an electronic control unit. Who the street signage elements clearly recognized (Ver same with stored reference images), the Headlights whose direction of radiation can be controlled, controlled to temporarily illuminate these signs. Movement parameters of the vehicle are taken into account so that the headlight even when approaching the Shield remains aligned on this.

Signage is preferred only if there is a negative impairment of oncoming road users is excluded. Also In this regard, conclusions can be drawn from the image analyzes pull before the headlight is activated. is For example, there is an opposite lane in the path between Headlights and traffic sign (for example, in right-hand traffic  in a left turn), the headlight only activated if the opposite lane is free.

It is also an advantage if the headlight not suddenly for illuminating traffic signs is switched on / off as this affects other road users could irritate. To avoid this, it will Headlight light with continuously increasing or decreasing brightness on or off.

The possible rate of change of the Beam direction of the headlamp is preferred limited to avoid flickering that both the driver of the vehicle as well as other road users could irritate. In this context, too set an upper limit frequency with which the beam direction from one traffic sign to another can change.

Are several illuminated traffic signs in The captured images are recognized in the control adds a selection of a sign to be illuminated Two criteria: On the one hand, signs are placed in a be certain distance in front of the vehicle is preferably illuminated and on the other hand, the traffic signs are weighted which according to their meaning. Have regulation signs top priority, danger signs with medium Priority illuminated and directional signs with lowest price ority, where there is overlap of the Priorities can come. Is the meaning / content of Traffic signs not automatically recognizable, the selection is only dependent on the distance dripped.

For lighting moving traffic signs the headlight is generally not activated. Of  further it is only switched on when the picture analysis shows that the sign is darker for the driver appears as a predetermined limit. After scarfing of the headlight aligned with the sign reanalyzed the image. On the one hand, it is checked whether the traffic sign was recognized correctly. on the other hand is compared whether the image quality with traffic sign lighting is better than without. Is the quality worse, which may be the case with fog, for example the headlight is switched off.

The system for illuminating street signs change elements should be by means of a special control element can be activated by the driver when the vehicle headlights are switched on.

Further details of the invention emerge from the following description of an embodiment , game. The associated figure shows an inventive Motor vehicle in a driving situation on a street.

A motor vehicle 1 is located on the right lane 2 of a road 3 , for which right-hand traffic is prescribed. The section of road 3 shown has no curvature. On the right side of the road there are two road signage elements 4 , 5 in front of the vehicle, the sign 4 being an overtaking bots sign and the sign 5 being a sign for identifying an upcoming double curve.

The vehicle 1 is equipped with a camera, by means of which a space lying in the direction of travel of the vehicle 1 is observed. This is schematically illustrated by an oval 6 and auxiliary lines 7 , the camera being arranged here in the region of an interior rear-view mirror of the vehicle 1 . The camera can initially be part of a system for lane detection or another driver assistance system. It recorded the space above street 3 and the room adjacent to street 3 , which included signs 4 , 5 , among others. The data captured by the camera are sent to an electronic control unit (not shown) for evaluation. Reference images of road signage elements are stored in a memory of the control device, and the control device checks whether one or more of these signs appear in the images originating from the camera. In the example, the signs 4 , 5 would be recognized in the camera images. In the next step, the control unit (program in the control unit) determines the position of the signs 4 , 5 relative to the vehicle 1 . It is then compared with values from a stored reference list whether the signs 4 , 5 appear sufficiently bright in the recorded images - that is, whether they are thus clearly visible to the vehicle driver. If the brightness of the signs falls below a distance-dependent limit, an algorithm is run through in which a decision-making process for the automatic additional lighting of a sign 4 or 5 takes place.

If there is only one sign 4 or 5 in the image, this is illuminated by means of an additional headlight 8 , which in the example is arranged in the area of a right-hand exterior mirror. If, as in the example, several shields of 4 , 5 are included in the image, two values are read from the distance of the respective shield 4 , 5 and the meaning of the shield 4 , 5 (reference image list) from the memory of the control unit, from which a decision value for each shield 4 , 5 is calculated. In the example, the sign 4 could be 70 meters away from the vehicle (distance value 1 , 2 ) and the sign 5 could be 130 meters away (distance value 0.6). Both signs have the meaning value 3 (sign 4 : regulation sign; sign 5 : danger sign with high priority). This results in a decision value of 4.2 for the shield 4 and a decision value of 3.6 for the shield 5 . The decision value changes during the approach to the signs 4 , 5 due to the changing distance value (see the following example reference list).

At distances <10 meters and <200 meters the distance value 0. If such a sign is recognized, it is not illuminated.

The sign 4 with the highest decision value is illuminated in that the headlight 8 with controllable radiation direction is aligned by the control device to the sign 4 and switched on in a dimmed manner when the vehicle 1 approaches the sign at less than 200 meters. Then, when the vehicle 1 is moving, the radiation direction of the headlight 8 is adjusted so that it always remains aligned with the shield 4 . If the vehicle is 1 up to closer than 10 meters to the shield 4 , the control unit would align the headlight 8 on the shield 5 , since this is then assigned the higher decision value. The pivoting of the radiation direction (auxiliary lines 9 ) of the headlamp 8 from the shield 4 to the shield 5 is carried out at a lower speed than a predetermined maximum value in order to avoid flickering.

The images from the camera are also evaluated with a view to oncoming traffic. The headlight 8 is only switched on when there is no glare for oncoming traffic associated with its operation.

The control unit only works in a way that controls the headlights 8 when the vehicle headlights (driving lights) are switched on and a special control element for switching on the sign lighting function was operated.
