Definitions
- the invention relates to a device for signaling a vehicle, in particular vehicles immediately following it, which has at least one light source which emits a visible laser beam, is detachable or non-detachable, and has a rigid or pivotable light source arranged on the vehicle.
- An optical signaling device is already known from German published application DE-OS 40 18 327, in which laser beams are emitted, for example, vertically upwards from a vehicle in order to draw the attention of subsequent road users to this vehicle.
- the laser beam can also be seen from a greater distance than a clearly visible line, in particular under unfavorable weather conditions such as fog, rain and snowfall.
- this document also proposes that its left rear group of lights emit a laser beam running counter to the direction of travel to the rear, obliquely outwards to the edge of the road and thereby horizontally. In a way, this creates a brightly colored control barrier, which should make it easier for subsequent vehicles to overtake the oversized vehicle.
- the known optical signal devices are each limited in their possibilities.
- the optical laser signal device mentioned can only be used for certain situations, in addition to the ones already mentioned, for example for securing accident sites and the blinking direction indicator.
- the main disadvantage of the device with the differently colored lights for signaling the driving speed condition is that the lights are provided with ordinary light bulbs and they may therefore be poorly recognized by the following vehicle in adverse visibility conditions and thus possibly too late.
- the invention is therefore based on the object of providing a device for signaling a vehicle, in particular vehicles immediately following it, which has at least one light source which emits a visible laser beam, is detachable or non-detachable, and has a rigid or pivotable light source which is arranged on the vehicle avoids the disadvantages of the known device.
- the aim of the invention is to ensure that such a device, especially in the case of unfavorable nissen and over a greater distance by a clearly visible but not dazzling signal signals the following vehicle the safety distance to be observed, for example in fog, rain or snow, with the device at the same time communicating the current driving state of the device provided vehicle should be enabled.
- This object is achieved according to the invention in a device of the type mentioned at the outset in that the optical axis of the laser beam is always directed toward the rear of the road in such a way that the resulting distance of the vehicle from the point of impact of the beam on the road is that of a safety distance to be observed immediately following vehicle corresponds.
- the device according to the invention can therefore be used to emit a readily recognizable light beam in the form of a laser beam which is also very moist, for example penetrating foggy air, over a greater distance than the light of conventional incandescent lamps.
- This laser beam is directed in such a way that it hits the road at a distance behind the vehicle which is dimensioned such that the point of impact indicates to the driver of the immediately following vehicle the safety distance to be observed.
- the laser beam emitted by the light source can be dosed in such a way that it has no dangerous or undesired effects on people and other physical objects. This requirement is met, for example, by a soft laser.
- the perception of the laser beam emitted by a preceding vehicle is particularly well possible for a following vehicle if the optical axis of the laser beam is approximately in the plane of symmetry or one formed by the longitudinal axis and the vertical axis of the vehicle to this parallel plane. Then the laser beam is directed in a straight line towards the back of the road. If the vehicle in front is approached too close, the laser beam is "driven straight in” so that the point of impact on the road cannot be seen by the driver in the vehicle immediately following it.
- the device is preferably designed such that the optical axis of the laser beam is directed obliquely downwards onto the roadway with respect to the plane of symmetry thereof, formed by the longitudinal axis and the transverse axis of the vehicle.
- the device is expediently attached in the central area of the vehicle roof facing the rear of the vehicle.
- the laser beam is emitted from a comparatively high and therefore easily recognizable position on the vehicle.
- the beam is therefore usually directed towards the roadway at a relatively large angle of inclination with respect to the horizontal plane of symmetry of the vehicle, which further improves the visibility of the beam.
- the attachment in the middle area also has a positive effect on the perception of the laser beam impact point when driving through tighter curves. As a result, this point usually remains on the road.
- the rear window is better protected against unauthorized access.
- the device By emitting a plurality of differently colored laser beams, information about the driving state of the vehicle emitting the beam is transmitted to the driver of another vehicle in an easily understandable manner. A specific driving condition is expressed by each color.
- the current driving state of the vehicle in front can also be determined at the same time. In a well-known traffic situation with a high traffic density and heavy fog at the same time, for example when driving at a higher speed on a freeway, the device can therefore be very helpful. With visibility ranges up to 50 meters, a red laser beam marking a safety distance of, for example, 70 meters will prompt subsequent vehicles to reduce their speed even before the vehicle in front is actually recognized, if the red color brakes the vehicle emitting the laser beam symbolizes.
- green laser beams which indicate that the vehicle is not braking allow that these vehicles can drive safely at a sufficient distance from one another, even with shorter visibility, without having to reduce their speed too much.
- the device according to the invention attached to them has two light sources each emitting at least one laser beam.
- the two light sources are at a distance of about 10 cm, for example, and emit different-colored parallel laser beams.
- a laser beam permanently emitted by the second light source in a uniformly valid special color can thereby be a characteristic indication of such a serve special vehicle.
- every subsequent road user knows immediately that the vehicle in front is one of the special vehicles mentioned by way of example. He is then warned and should approach this vehicle with the appropriate attention. Due to the parallel emission of the laser beams from the two light sources, the beam pointing to the special vehicle in the special color can be seen in good time in conjunction with the laser beams containing the other information about the driving state of the vehicle.
- An intermittent, that is to say pulsating or with short interruptions emitted laser beam can provide the following traffic participants with further information. Similar to a hazard warning lamp, such a beam could indicate a stationary vehicle.
- the invention proposes, inter alia, a pulse laser generator and a dye laser for the device.
- the pulsed emission of a laser beam can also be achieved simply by regularly interrupting the current flow in the light source.
- the invention advantageously proposes that the light sources or light sources are arranged so as to be pivotable or adjustably movable so that each laser beam is emitted at a certain desired angle of inclination to the roadway over the required safety distance and laterally at a certain desired angle with respect to the vertical plane of symmetry of the vehicle formed by the longitudinal axis and the vertical axis.
- the device is ideally designed in such a way that it automatically carries out the adjustment movements taking into account, for example, the road layout and position of the horizontal vehicle plane of symmetry with respect to the horizontal.
- each laser beam is also at the Driving on roads with crests, troughs and curves always at the correct distance, corresponding to the safety distance to be maintained, behind the preceding vehicle emitting the laser beam on the road.
- the automatic adjustment of the light source (s) can be controlled with the aid of special means. In order to take into account sections of road that have troughs and crests, this can be a radar device. In order to take road curves into account, on the other hand, for example, a control effect can be derived from the steering wheel position of the vehicle carrying the device according to the invention
- the device has additional means to determine from the own speed and the speed of the immediately following vehicle the appropriate safety distance depending on the weather and to move the optical axis of the laser beam into the corresponding position .

- 6 shows a light source according to the invention for emitting three laser beams in a perspective view
- Fig. 7 is a side view of a traffic situation as in Fig. 1, wherein the vehicle in front is a truck which is also provided with a device attached to the vehicle roof, and
- FIG. 7 shows a view from above of the traffic situation according to FIG. 7.
- FIGS. 1 and 2 In the traffic situation shown in FIGS. 1 and 2, two passenger cars (cars) 1, 2 drive one behind the other on a road 3 or a roadway 4 located thereon.
- the roadway 4 is characterized by the two vehicles 1, 2 in the direction of travel seen left lane edge marker 5 and right lane edge marker 6 limited.
- the lane 4 is divided into two lanes 8, 9 by a median mark 7, shown here as a broken line.
- the two vehicles 1, 2 drive in the right lane 9.
- the preceding car 1 is equipped with a device 10 according to the invention, which is located here in the middle of the vehicle roof 11 near the rear window 12.
- This device 10 and the associated laser light source 13 are thus at the same time in a plane of symmetry 16 formed by the longitudinal axis 14 and the vertical axis 15 of the vehicle 1 Center of gravity 18 of vehicle 1 run, spanning a horizontal plane of symmetry 19.
- the laser light source 13 emits a clearly visible laser beam 20 with a specific color or wavelength along an optical axis.
- the optical axis of this laser beam 20 is directed towards the rear against the direction of travel of both vehicles and obliquely downward relative to the horizontal plane of symmetry 19 of the vehicle.
- laser beam 20 strikes roadway 4.
- This point of impact 21 is located at a distance from the vehicle 1 emitting the laser beam, which corresponds precisely to the minimum safety distance to be maintained by the following vehicle 2. Since the following vehicle 2 is located behind the point of impact 21 shown in FIGS. 1 and 2, it therefore travels at a sufficient distance from the vehicle 1.
- the device 10 is held on the vehicle roof 11 by magnets 23, that is to say releasably, which is shown here only in a section for the purpose of better visibility of the device 10.
- the device 10 contains the laser light source 13, which can be powered by a battery and is not shown here.
- the laser beam 20 emerges from the light source 13 at the opening 24.
- the light source 13 is arranged in a holding part 25 in such a way that it, and thus also the optical axis of the laser beam 20, into each of them by means of a height adjustment screw 26, which is mounted in bearing pieces 25a, 25b of the holding part 25 and with which it is connected because the desired direction can be pivoted onto the roadway 4 and locked.
- This pivotal movement takes place under Formation of an angle between the optical axis of the laser beam 20 and the horizontal plane of symmetry 19 of the vehicle formed by the longitudinal axis 14 and the transverse axis 17, cf. Fig. 2.
- the light source 13 is fastened to the lower end 27a of a side adjustment bolt 27.
- This side adjustment bolt 27 extends through the height adjustment screw 26, specifically in its central area and at right angles to its axis. Fixing the side adjustment bolt 27 and thus the light source 13 in the desired position is possible by means of a grub screw 28 which also extends through the height adjustment screw 26.
- the lateral pivoting of the light source 13 takes place with the formation of an angle between the optical axis of the laser beam 20 and the vertical plane of symmetry 16 of the vehicle formed by the longitudinal axis 14 and the vertical axis 15, cf. Fig. 1.
- the height and the side adjustment, the light source 13 or the optical axis of the laser beam 20 can be precisely adjusted so that the laser beam 20 is emitted in the required direction.
- the laser light source 29 according to FIG. 6 has three outlet openings 30, 31 and 32 for a laser beam 33, 34 and 35 each with a specific color.
- the emission of three differently colored laser beams 33, 34 and 35 possible with this embodiment can be carried out in the presence of three appropriately designed laser generators, not shown in detail
- Light source 29 can be realized.
- Each laser generator accordingly generates a special laser beam 33, 34 and 35, which is then emitted through the associated outlet opening 30, 31 and 32.
- a so-called dye laser (not shown in the drawings) can also be used, with which a broadband laser beam with a certain wavelength range can be emitted.
- a so-called diffraction grating is introduced instead of the mirror which is otherwise partially used in lasers and is partially transparent to the emerging laser beam. By changing the grating position, a wavelength can then be filtered out of the emitted area as a laser beam with a specific color.
- a single exit opening for the differently colored laser beams is therefore sufficient.
- Each laser beam 33, 34 and 35 along with the associated color can thus be assigned a specific message about the driving state of the vehicle to which the corresponding light source 29 is attached.
- a green ray 33 can indicate a vehicle traveling at undiminished speed.
- a red beam 34 can in turn indicate a vehicle traveling at a reduced speed, for example a braking vehicle.
- a stationary vehicle can be signaled to other road users with a yellow laser beam 35.
- FIGS. 7 and 8 Another embodiment of the invention is shown in FIGS. 7 and 8. These two representations are analogous to FIGS. 1 and 2.
- the vehicle 37 driving ahead of the vehicle 36 on the road 4 in the traffic situation shown is a truck.
- the truck 37 is equipped with a special embodiment of the device 38 according to the invention, which is attached at the rear end in the middle of the truck roof 39.
- the special feature of this device 38 compared to the device according to FIGS. 1 to 4 is that it contains two light sources 40 and 41 each emitting a laser beam of a different color.
- the light beam 40 emits the laser beam 42 facing the right lane marking 6 and the light source 41 the laser beam 43 facing the left marking 5.
- the optical axes of the two beams 42, 43 are at a parallel distance from each other against the direction of travel to the rear and towards the horizontal plane of symmetry of the truck 37 obliquely downwards on the roadway 4. This results in the point of impact 44 for the beam 42 and the point of impact 45 on the road 4 for the beam 43, provided that the car 36 is driving behind the truck 37 at a sufficient distance.
- both beams 42, 43 have the same effect as was described for the laser beam 20 with reference to FIGS. 3 and 4.
- the driver of the following vehicle 36 is already advised of the truck 37 driving ahead as a special vehicle by the characteristic color of the laser beam 43, and is therefore required to take particular care at an early stage if he approaches it.
- a light source 29 according to FIG. 6 or a dye laser can also be provided in the truck 37 to assist the driver of the To inform passenger car 36 about the driving condition of truck 37.
