Opfindelsen angår en i kørselsretningen fremadvirkende sigtbarhedsmå-ler til motorkøretøjer, hvorved føreren til stadighed under kørsel kan være å jour med sigtbarhedsforholdene inden for en i forvejen fastsat afstand foran køretøjet. Sigtbarhedsmåleren er af den art, 5 der består af en afstandsmåler, hvis 2 lygter udsender lysstråler frem imod et målepunkt i en i forvejen fastsat afstand foran køretøjet og inden for førerens normale synsfelt således som nærmere angivet i krav l's indledning. Opfindelsen giver en færdselssikkerhedsmæssig foranstaltning imod kørselsulykker, der forekommer på lo grund af for høj hastighed i forhold til nedsat sigtbarhed. I medfør af opfindelsen vil føreren kunne efterleve den tilpasning af hastigheden, som den derved også af føreren selv målte sigtbarhed øjeblikkeligt måtte give anledning til, som det er forklaret nedenfor.The invention relates to a forward-looking visibility meter for motor vehicles, whereby the driver can be constantly updated while driving visibility within a predetermined distance in front of the vehicle. The visibility meter is of the type 5 consisting of a rangefinder whose 2 lamps emit light beams towards a measuring point at a predetermined distance in front of the vehicle and within the normal field of view of the driver as specified in the preamble of claim 1. The invention provides a road safety measure against road accidents that occur due to excessive speed in relation to reduced visibility. By virtue of the invention, the driver will be able to live up to the adjustment of the speed, which, as a result, the visibility measured by the driver himself must immediately give rise to, as explained below.

15 Det er hidtil kendt, at sigtbarhedsmålinger foretages på vejrstationer rundt om i landet og derfra videresendes gennem medierne til generel orientering for befolkningen. Ved de kendte sigtbarhedsmålin-ger foretages disse almindeligvis ved visuel betragtning af i forvejen kendte, faste målepunkter. Endvidere foretages sigtbarhedsmå-2o ling under bevægelse, dog ligeledes over for faste, stillestående målepunkter, herunder motorkøretøjsføreres anvendelse af km-afmærk-ninger i vejsiden til afstandsmåling, og hvor både hastighed og reaktionstid kan have indflydelse på måleresultatet.15 So far, it is known that visibility measurements are made at weather stations around the country and then transmitted through the media for general information to the population. In the known visibility measurements, these are usually made by visual consideration of previously known fixed measurement points. Furthermore, visibility measurement is carried out while moving, but also towards fixed, stationary measurement points, including motorists' use of km markings in the road side for distance measurement, and where both speed and reaction time can affect the measurement result.

25 Pra DE offentliggørelsesskrift nr. 2211578 og PR offentliggørelsesskrift nr. 2629403 kendes målearrangementer af lignende type som nævnt indledningsvist. Disse målearrangementer er fortrinsvis beregnet til måling af sikkerhedsafstand til et forankørende køretøj, idet 2 lygter fra eget køretøj rettes mod det forankørende køretøj, 3o hvorpå et målepunkt kan afbildes. I PR publikationen nævnes muligheden for at inddrage sigtbarhedsmåling, dog ikke konkret, hvorledes dette gøres.25 Pra DE Publication Publication No. 2211578 and PR Publication Publication No. 2629403 are known for measuring arrangements of a similar type as mentioned initially. These measuring arrangements are preferably intended for measuring the safety distance of an oncoming vehicle, with 2 lamps from their own vehicle being directed to the oncoming vehicle, 3o on which a measuring point can be imaged. The PR publication mentions the possibility of including visibility measurement, but not specifically how this is done.

Det er opfindelsens formål at anvise en sigtbarhedsmåler af den i 35 krav l's indledning angivne art, således at målingen kan foretages, uden at der skal være et forankørende køretøj til stede.It is an object of the invention to provide a visibility meter of the kind specified in the preamble of claim 1 so that the measurement can be made without the presence of an oncoming vehicle.

DK 168500 B1 2DK 168500 B1 2

Bette formål opnås ved, at lygterne udsender en fremadrettet samlet lysstråle/kernestråle, der begge er ind justeret til at ramme vejbanen og belyse denne i et fælles punkt i en i forvejen fastsat afstand foran køretøjet, ς På denne måde kan en visuel sigtbarnedsmåling altid foretages i en given afstand, der forøvrigt er uafhængig af køretøjets hastighed.For better purposes, the lamps emit a forward unified light beam / core beam, both of which are adjusted in order to hit the roadway and illuminate it at a common point at a predetermined distance in front of the vehicle ς In this way, a visual sight child measurement can always be made at a given distance which is otherwise independent of the speed of the vehicle.

Ved justering af lygternes stilling kan der fremkaldes et belyst målo lepunkt på vejbanen f.eks. 50 meter foran køretøjet, der samtidig belyser vejbanen umiddelbart foran køretøjet med et lysmønster af den art, der er kendt fra eksisterende tågelygter. Sammensætningen af såvel en samlet, kraftig lysstråle som et spredt lysmønster ifølge opfindelsen, udsendes fra hver af afstandsmålerens 2 lygter.When adjusting the position of the lights, an illuminated target point can be developed on the roadway, for example. 50 meters in front of the vehicle, which simultaneously illuminates the roadway immediately in front of the vehicle with a light pattern of the kind known from existing fog lamps. The composition of both a combined, powerful light beam and a scattered light pattern according to the invention is emitted from each of the lamps 2 of the rangefinder.

15 lygterne skal afgive lys af hvid eller gullig (selektiv gul) farve. Anbringelse og tilslutning af lygterne foretages i overensstemmelse med de herfor gældende retningslinier.The 15 lamps must emit light of white or yellow (selective yellow) color. Installation and connection of the lamps shall be carried out in accordance with the relevant guidelines.

Et ved opfindelsen fremkaldt og for føreren synlig belyst målepunkt 2o på vejbanen i den fastsatte afstand foran køretøjet, er således det for ham sikre udtryk for, at sigtbarheden inden for denne afstand foran køretøjet er til stede, hvorimod en dårligere sigtbarhed end denne vil forhindre et for føreren synligt målepunkts forekomst på vejbanen i den fastsatte afstand foran køretøjet, som en øjeblikke-25 lig advarsel om, at sigtbarheden er under den fastsatte minimumsgrænse, hvilket medfører særlig opmærksomhed, samt at hastigheden-øj eblikkeligt nedsættes. Graden af en eventuel tiltagende sigtforringelse vil fremgå af de to lysstråler, hvis for føreren synlige længde vil afkortes i takt med yderligere sigtforringelse.Thus, a measurement point 2o produced by the invention, which is clearly visible to the driver, on the roadway at the predetermined distance in front of the vehicle, is the assurance to him that the visibility within this distance in front of the vehicle is present, whereas a poorer visibility than this will prevent a the occurrence of visible points of measurement on the roadway at the specified distance in front of the vehicle, as an immediate warning that visibility is below the set minimum limit, which causes special attention, and that the speed-eye is immediately reduced. The degree of possible increasing visibility deterioration will be indicated by the two light rays if the visible length of the driver will be shortened as further visibility deterioration occurs.

3o3o

Af hensyn til modgående trafik kan målepunktet vælges i den fastsatte afstand foran køretøjet, men forskudt til siden for køretøjets forlængede centerlinie.For the sake of oncoming traffic, the measuring point can be selected at the fixed distance in front of the vehicle, but offset to the side of the vehicle's extended center line.

35 I en særlig udførelsesform for sigtbarhedsmåler ifølge opfindelsen udsendes lysstråler til afstandsmåling fra arrangementer, der ind- 3 DK 168500 B1 bygges sammen med, eller er en del af køretøjets eget lygtearrangement .35 In a particular embodiment of visibility meter according to the invention, light rays are emitted for distance measurement from arrangements built in with, or are part of, the vehicle's own lamp arrangement.

I en anden udførelsesform kan lysstråler af enhver art til afstands-5 måling ifølge opfindelsen udsendes fra et hvilken som helst sted på eller i køretøjet.In another embodiment, light rays of any kind for distance measurement according to the invention can be emitted from any location on or in the vehicle.

Afstandsnålingen kan eventuelt foretages elektronisk, således at resultatet kan videretransmitteres til føreren for instrumental aflæs-lo ning eller ved tilkendegivelse gennem lyd- og/eller lyssignaler.Optionally, the spacer can be performed electronically, so that the result can be transmitted to the driver for instrumental reading or signaled by audio and / or light signals.
