DE3129094A1 - Advance warning device for motor-vehicle traffic - Google Patents

Abstract

The innovation indicated is intended for use on roads, primarily motorways, motorway approach roads and exits and on level-crossings. The main components are a transmitting device (1, Fig. 1) and transmitters (55, 57, Fig. 5), and receivers with a display unit (31, Fig. 2) in the motor vehicle. The commands to be transmitted, for example, "congestion", "slippery surface", "driver on the wrong side of the road", are fed to the transmitters (55, 57, Fig. 5) along the motorway by the transmitting device (1, Fig. 1). The transmitters can be operated individually and jointly and separately according to direction of travel or jointly. A receiver in the motor vehicle picks up the transmitted command and makes it optically and acoustically perceptible on the display unit. Other transmitters with a continuous pulse (53, Fig. 4) on the motorway approach roads set the vehicle receiver automatically to the reception frequency belonging to the direction of travel. By means of transmitters (54, Fig. 4) erected in the direction counter to motorway exits, a warning signal "stop" is triggered on the display unit when the driver enters them from the wrong direction. Similar transmitters with a continuous pulse (61, 63, Fig. 3) in the region of level-crossings trigger a warning signal "train" when a train is approaching. <IMAGE>

Description

Advance warning device for motor vehicle traffic

The indicated innovation concerns the area of advance warning devices in motor vehicle traffic, primarily on motorways and restricted and preferably unrestricted railroad crossings, but can also be used with appropriate expansion for the. Can be used on main and secondary roads.

Above all on motorways, horrific accidents occur in fog, Wetness, black ice, sudden traffic jams or incorrect entry into the Autobahn (wrong-way driver). At railroad crossings, the approaching has to be overheard Train or poor insight into the routing very often serious accidents result.

As is well known, the current warning system takes a lot of time, bia the message about slipperiness, fog or congestion in the transmission centers of the traffic transmitters and then as a warning message on the radio? if it's turned on at all is., is transmitted to the driver.

Likewise, the current security precautions are in the area The freeway entrances and exits are not optimal, so it always turns out to be the wrong one Driving into the Autobahn (wrong-way drivers). Is a wrong-way driver on the way the warning message often comes too late or according to the section of motorway being traveled on too imprecise.

Try to have a sufficient early or early morning for all of these circumstances To install Vorarnsystern failed because of the known high costs and came not beyond the testing stage.

This is where the invention comes in. Assuming that it is possible today is to build small transmitters and receivers for relatively low costs and under Incorporating ready existing facilities, this was described below Innovation developed, which is a cost-saving but fully operational early warning system represents.

Roughly speaking, this innovation consists of three components: transmitter, Sender and receiver. The driving directions of the highways are beneficial in two Divided into groups: for example, the direction of travel north-south and west-east in "A", the driving directions south-north and east-west in "B".

A transmitter chain along the motorway, hereinafter referred to as pulse generator, works on the directions "AIt" and "B" on different frequency ranges, so that a separate, independent signal transmission is possible. the Directional marking of the motorways could for example be on the traffic signs be attached to the motorway entrances and the signs along the motorway a switch on the receiver in the motor vehicle could then, for example, be the corresponding one Direction channel can be switched on.

A much safer, because inevitable activation of the receiver on the applicable reception area would, for example, include pulse generators To set up a continuous pulse at the freeway entrances, 'which automatically when driving through switch on the correct direction channel "A" or "B".

For this version it would be advantageous if the receiver in the motor vehicle would be made ready to receive when the ignition was switched on.

For further signal transmission the presence of directed lipuis donors along the motorway at favorable intervals. Offer for this For example, the already existing emergency telephones can be integrated into the pulse generator could be built in. Such pulse generators could then, for example, to transmit warning signals from a transmission center to be described the existing cable network of the emergency telephones received, these, pulse generators are for example designed so that they can transmit the following signals: fog; Wetness; Smoothness; Traffic jam; Diversion and wrong-way drivers.

A transmission center, for example, the one for the motorway section belonging to the police station, has a transmission device -that is the same Releases signals to the pulse generators along the motorway for transmission. This could be advantageous for both directions of travel separately and switchable at the same time. It is also advantageous if the pulse generators are numbered consecutively along the motorway and are individually controlled by the transmission device in the transmission center could. This measure ensures precise signal transmission to the, for example Route endangered by wrong-way drivers. It is useful if everyone has the ability to transmit signals a separate delete key (facility) is assigned.

A receiving device ii motor vehicle, of conventional design, could Find space under the bonnet, while the display device is on the dashboard in the The driver's field of vision could be attached. This display device has, for example Illuminated symbols that correspond to the transmitted signals, that is: fog; Wetness; Smoothness; Traffic jam; Diversion and wrong-way drivers. A uniform, with the light signals A coupled acoustic signal is advantageous; an extinguishing device is advantageous for this acoustic signal, but not advisable for the visual one.

The kind of gate signal transmission by the pulse generator along the highway would have to be uniform and could be in the field of infrared technology, ultrasound technology, laser technology as well as in the area of radio frequencies.

The innovation described will now be explained in more detail by means of two examples will.

Example one: In the area of the numbered pulse generators along the Motorway, for example emergency telephones, six to twenty-one, both directions "A" and "B" are heavy fog. For security reasons, a large enough Range selected, for example the range of the emergency telephones three to twenty-four.An a transmission device in a transmission center are indicated by appropriate number keys -the Emergency telephones three to twenty-four switched on. For example, both direction buttons "A" and "B" actuated and the "Fog" signal sent. A motor vehicle with the Receiver, which is in the detection area of the pulse generator three of the direction of travel "A" or "B" arrives, the transmitted signal "Fog" picks up0 The indicator light "Fog" lights up and the acoustic signal sounds at the same time. The driver is warned in good time and can adapt his speed to the circumstances. If the motor vehicle comes out of the area of the pulse generator twenty-four, the optical and acoustic signal display in the vehicle go out because the impulse transmitter twenty-five the warning signal "fog" no longer sends. The driving directions "A" and t ° B "are free again, it can be driven without hindrance.

Example two: In the direction of travel "A" has up to the pulse generator eight a traffic jam is formed, between the impulse generators three and four is a departure. The following are switched on on the transmission device of a transmission center: Direction of travel "A @" the number keys four to eight and the signal "traffic jam". The number keys one to three and the signal "traffic jam diversion".

If a vehicle comes in the direction of travel "A" in the area of the pulse generator one, the "traffic jam - diversion" indicator lights up and the acoustic signal sounds at the same time Signal. The driver knows that a traffic jam has formed, but there is still before a departure for a detour.

In a vehicle behind the exit, only the indicator lights up "Traffic jam", there is no diversion. Has the first vehicle described If you missed the exit, the indicator light "diversion" goes out, the indicator "A" - "traffic jam" remains. A diversion is no longer given. In both cases, the However, drivers are warned in good time and can adapt their driving style to the situation For example, all warning signals can be transmitted and received in the same way will.

To warn of wrong entry (wrong-way drivers) into the autobahn, For example, pulse generators with a permanent pulse can be installed at the exits, at petrol stations or set up rest areas that send in the wrong entry direction. In the motor vehicle a light signal, for example "Stop", lights up and sounds in a favorable manner at the same time an acoustic signal when the motor vehicle is wrong in the highway comes in. Both signals only go out automatically after the turns.

Similar pulse generators can be used in the area of unrestricted or also set up barrier-free level crossings. When entering the reception area Favorably lights up a light indicator, for example "train" and sounds advantageously an acoustic signal again. The driver is warned, he is in the area of a railroad crossing.

Such a continuous pulse generator in the area of a railroad crossing can be replaced by a pulse generator that is activated by a switch (or existing train signaling devices) in the tracks at a safe distance at the beginning of the transition could be arranged by the passing train in and out is switched off again. This would probably look unpleasant Continuous pulse replaced by a pulse that is only noticeable when a train is approaching.

Receivers for installation in motor vehicles may well depend on Price range can be designed differently. It is conceivable instead of the illuminated display a Digitron display that writes out the warning signs, for example in connection with an acoustic signal. The warning signals could, for example, also to be expanded: "Accident"; "bad roadway"; "Construction site"; "Narrowed roadway"; or "drive in one lane", for example to avoid the fast lane in the event of an accident Removal of injured persons to make free. There is also the Possibility of the diversion, for example "U -9, to be specified. The warning signals could also be implemented in a suitable foreign language or be replaced by symbols. The latter also for recipients without Digitron display. Another expansion of a receiver, for example, at the same time as a transmitter and the impulse generator along the highway is simultaneously as a receiver possible. In this way, a driver of an Eraftfahrges can send a warning message the transmission center, for example "black ice" or §'Unfall ". The transmission center could then warn the following motor vehicles accordingly. This extension should not be advisable, however, as the dangers of abuse are too great could.

The invention is described below using an exemplary embodiment Describing with reference to the drawing, D, drawings show: Fig. 1 A control panel a transmission device for installation in a broadcasting center.

Fig. 2 A light indicator field of a receiver for the building in a Motor vehicle.

Fig. 3 A display panel of a receiver with Digitron display for the Installation in a motor vehicle.

Fig. 4 An entry-exit area of a motorway, drawn as a site plan, with a pulse generator for the automatic activation of a direction channel and an impulse generator for warning against wrong entry into a motorway.

Fig. 5 A section of the motorway with the directions "A" and "B" and pulse generators in both directions of travel on the motorway, drawn as a site plan.

Fig, 7 An unrestricted railroad crossing as a site plan, with a Pulse generator for the warning of an approaching train with indicated switching contacts in the tracks for the activation and deactivation of a pulse generator by the train.

According to Fig. 1, a transmission device 1 for a transmission center a skin, in which a switching technology of a known transmitting device is housed is. On the front of the housing you can see Digitron displays 2 and 3, which are already Play back entered send commands.

Control devices are located in front of Digitron displays 2 and 3 for the input of send commands that are used for input control by the Digitron displays 2 and 3 can be played back. With a switch 14, the transmission device can be switched on and off.

Keys 4 and 6 are used to enter the directions of travel to be determined "A" and (or) "B". These buttons 4 and 6 are assigned to correct incorrect entries Extinguishing devices 4a and 6a. With buttons 15 to 24, which in turn are extinguishing devices 15a to 24a are assigned, are those responsible for the or the send command Pulse generator 55 or (and) 57 Fig. 5 determined along the highway. These initiators 55 and 57 Fig. 5 are numbered and can therefore be specifically addressed Key 25 Fig. 1 fixes the preselected numbers of the pulse generators 55 and 57 Fig. 5, which means that two-digit and multi-digit numbers can also be transmitted.

Keys 8 to 13 Fig. 1, which again delete keys 8a to 13a for a Corrections are added, are used to input warning signals such as fog; Wetness; Traffic jam; Detour; Wrong driver; for those previously determined by keys 4 or 6 Directions of travel and pulse generators 55 or 57 fixed by buttons 15 to 24 Fig. 5 along the highway. By pressing a button 26 Fig. 1 there is Transmission device releases the entered data, pulse generators 55 and (or) 57 Fig. 5 send out the warning commands.

The transmission signals appearing in Digitron field 2 Fig. 1 are Entered as follows: Activate the direction of travel, press 4, "A" appears.

Press the "Sins", number keys 15 to 24, and the enter key 25, "Sins" appears. Press the "eight", number key 15 to 24 and the key 25, it appears .... "Eight". Press "Fog", "Fog" appears, keys 8 to 13. The other lines of Digitron field 2 are entered in the same way. In the same way, all send commands can be sent to the directions of travel "A" digitron field 2 and direction of travel "B", Digitron field 3, can be entered. Will now be the one already described If button 26 is pressed, the warning commands entered are sent by the corresponding Im pulse generator 55 and (or) 57 Fig. 5 sent.

Fig. 2 shows a front panel of a 'receiver -31 with an illuminated display for use in a motor vehicle. Will not be the recipient in principle switched on by switching on the ignition of the engine, so this is done by a switch 32 Fig. 2. The light indicators 33 and 34 are switched on by a pulse generator 53 of a motorway entrance 47 with a continuous pulse. It lights up depending on the direction of travel the indicator light 33 "A" Fig.2 or 34 "B". Warning lights 35, 36, 37, 38, 39 light up according to the command signal which is emitted by the pulse generators 55, 57 Fig. 5 along the highway. Simultaneously when one of the warning lights 35 to 39, FIG. 2 lights up, a sound trumpet sounds 43 an acoustic signal, which can be restored by an extinguishing device 44 upon request can be turned off. the illuminated display 35 to 39 can cannot be deleted. A light indicator 40 works in the same way Illumination of a warning light 41 indicates that the vehicle is wrongly on the highway enters and into the transmission range of a continuous pulse generator 54 Fig.4 of a motorway exit 48 has arrived. In this case too, the switching funnel 43 Fig. 2 sounds the acoustic signal.

A warning light 41 Fig. 2 lights up with an acoustic signal indicates that the vehicle is in the range of a pulse generator 61 or 63 Fig. 6 a Railway crossing with continuous impulse has arrived. But also lights up when the railroad crossing is equipped with pulse generators 67 and 69 Fig. 7, which by the incoming train can be switched on via switch 71.

Fig. 3 shows a front panel of a receiver 45 for use in motor vehicles with a Digitron display 46. Here, too, there was a switch again 32 a provided for switching on the receiver, if the switching on is not fundamentally takes place with the engine ignition. Indicator lights 33 and 34 again indicate the direction of travel "A" and "B" on, a horn 43 lets out an acoustic signal again, that can be switched off again by a key 44.

In the case of a receiver version with such a Digitron display 46 according to FIG. 3, it is also possible by means of a key 27 according to FIG. 1 and through the number keys 15 to 24 Fig. 1 a recommended diversion, for example ß U " U to transmit. which then appears written out in Digitron field 46 Fig. 3. These Redirection recommendation can be made using buttons 28 and 29 on a transmission device Fig. 1 can be deleted again separately according to the direction of travel "A" and "B".

It is advantageous if the light displays for the directions of travel "A" and "B" 33 and 34 according to FIGS. 2 and 3 are designed as on / off switches. This is for the case that there are no permanent pulse generators at motorway entrances 47 according to FIG. 4 53 are available, but the respective direction of travel "A" or "B" according to the traffic signs must be switched on manually.

FIG. 4 shows an entry and exit area of a motorway with the entry lane 47 and the exit lane 48. At the entry lane 47 is a continuous pulse generator 53 arranged, which when driving through its transmission range with a motor vehicle with the receiver switched on, switches on the associated direction of travel channel "B". A continuous pulse walker 54 can be seen on the exit lane, which lights the warning light 40 Fig. 2 "Stop" switches on or in the Digitron display 46 Fig. 3 the words "Stop "Appears to warn the driver of the motor vehicle that he is in the wrong place In the direction of a motorway (wrong-way driver). This warning sign "Stop" only goes out after the vehicle has turned. 4 can also be seen the motorway lane 50 is marked with the entry lane 49 in east-west direction as the direction of travel lane "B", the motorway median 52 and the motorway lane 51 in west-east direction, marked as driving direction lane nA ".

In Figure 5, a motorway section is shown on which the direction of travel lane 50 "B" and 51 "A" can be seen again. There are pulse generators on the direction of travel lane 50 "B" 55 recognizable by the direction of travel lane 51 "A" pulse generator 57. These send how already described above, the input by a transmission device according to Fig.1 Warning signs off. The transmission direction of the pulse generator 55 and 57 are shown schematically 56 and 58 indicated. 52 is the middle tire of the motorway.

An unrestricted railroad crossing is shown in Fig. 6 with the tracks 59 and the transition 60 shown. Pulse generators with a continuous pulse are indicated 61 and 63 with the indicated Bichtatrahlen 62 and 64. These switch into one Receiver according to Figure 2 and Figure 3, the warning signal "2ug" as soon as a motor vehicle reaches the transmission range with the receiver switched on. The arrangement of Je a pulse generator 61 and 63 on each side of the tracks 59 Fig.6 has proven advantageous proven, since with only one pulse generator the passing train interrupts a directional beam can and therefore no warning signal is switched on in the receiver on one side of the track.

7 shows a railroad crossing with tracks 65 and the crossing 66.

Pulse generator 67 and 69 with the directional beams 68 and 70 are again arranged on both sides of the tracks. These pulse generators 67 and 69 do not emit a continuous pulse from, but are via.Schalteinrichtungen 71, which are integrated on the tracks are, through this switching device is switched on and off when a train is driven over. Achieved by this measure nan that that might be annoying The continuous pulse to be sensed is replaced by a pulse, which is then only a warning signal "Train" broadcasts when a train actually approaches the level crossing.

The invention shown in hi @ r shows a comprehensive warning device for motor vehicle traffic. Their functionality was verified through a small test proven on the basis of infrared technology.
