Description

537 932 LARMNING DA ETT FORDON HAMNAT UTANFOR TRAFIKERBART OMRADE TEKNISKT OMRADE Detta dokument beskriver ett forfarande och en berakningsenhet i ett fordon. Narmare bestamt anges ett forfarande och en berakningsenhet for larmning till en larmcentral d5 ett fordon hamnat utanfor trafikerbart omrade till foljd av exempelvis en olycka. 537 932 ALARM DA A VEHICLE PORTED OUTSIDE TRAFFIC AREA TECHNICAL FIELD This document describes a procedure and a calculation unit in a vehicle. More specifically, a method and a calculation unit for alarming to an alarm center where a vehicle has ended up outside a traffic area as a result of, for example, an accident.

BAKGRUND Ett fordon kan komma att r5ka ut for en olycka under !corning, som exempelvis krock, dikeskOrning, avakning av vagen etc. BACKGROUND A vehicle may be involved in an accident during a collision, such as a collision, ditch collision, road clearance, etc.

Med fordon avses i detta sammanhang exempelvis lastbil, langtradare, flakbil, transportbil, hjullastare, buss, motorcykel, terrangbil, bandvagn, snoskoter, stridsvagn, fyrhjuling, traktor, personbil eller annat liknande motordrivet bemannat eller obemannat transportmedel, anpassat kir land baserad geografisk fOrflyttning. In this context, vehicles refer to, for example, lorries, lorries, flatbed trucks, transport vehicles, wheel loaders, buses, motorcycles, SUVs, tracked vehicles, snowmobiles, tanks, quadricycles, tractors, cars or other similar motorized or unmanned means of transport, adapted to land based geographical movement.

I manga fordon av denna typ finns en inbyggd sandare for att sanda en larmsignal till en larmcentral da en olycka intraffar. Det forutsatts dock vanligen att foraren sjalv aktiverar denna larmsandare genom att trycka in en knapp p5 instrumentpanelen, eller liknande. Nagot som kanske inte är mojligt att Ora far foraren om denne skadats. Foraren kan aven 20 vara sa omskakad och/ eller stressad aft han/ hon inte tanker p5 att skicka en larmsignal. Alternativt kan foraren vara upptagen med aft utfora forstahjalpen p5 en medpassagerare eller annan skadad trafikant. Many vehicles of this type have a built-in transmitter to send an alarm signal to an alarm center when an accident occurs. However, it is usually assumed that the driver himself activates this alarm transmitter by pressing a button on the instrument panel, or the like. Something that may not be possible for Ora to hit the driver if he is injured. The driver may also be so shaken and / or stressed that he / she does not think about sending an alarm signal. Alternatively, the driver may be busy performing first aid on a fellow passenger or other injured road user.

En tankbar lOsning p5 detta problem kan vara aft aktivera larmsandaren i fordonet automa- tiskt dá en krockkudde i fordonet utloses. Ett problem med en sadan losning är dock att krockkudden kanske inte utloses da ett tungt fordon exempelvis Icor av vagen och fortsatter ut p5 en aker eller liknande, utan aft kollidera med nagot storre forernal. En sadan olycka kan, trots att krockkudden inte utloses (eller kanske just darfor), orsaka en skada p5 foraren som gOr honom/ henne ofOrmOgen att larma sjalv. Vidare är det vanligt i vissa typer av 30 fordon som exempelvis bussar, att det helt enkelt inte finns nagra krockkuddar. A possible solution to this problem may be to activate the alarm transmitter in the vehicle automatically when an airbag in the vehicle is triggered. A problem with such a solution, however, is that the airbag may not be triggered when a heavy vehicle, for example Icor off the road and continues out on a field or similar, but collides with a somewhat larger forernal. Such an accident can, even though the airbag does not deploy (or perhaps for that reason), cause an injury to the driver that makes him / her unable to alarm himself / herself. Furthermore, it is common in certain types of vehicles, such as buses, that there are simply no airbags.

Detta problem med att alstra och skicka en larmsignal vid en olycka är kanske extra angelaget i samband med singelolyckor som av5kningar av vagen och liknande, d5 det i dessa fall ofta inte finns nagon annan trafikant i narheten som lagger marke till olyckan och kan larma. En efterfoljande trafikant vid en avakning lagger kanske inte marke till det forolycka- 1 537 932 de fordonet, exempelvis till foljd av nedsatt sikt, marker, kraftig nederbOrd, dimma, blandande solljus eller liknande; faktorer som i sig ocksa okar sannolikheten for en trafikolycka. This problem with generating and sending an alarm signal in the event of an accident is perhaps particularly important in connection with single accidents such as deviations of the road and the like, as in these cases there is often no other road user nearby who signals the accident and can sound the alarm. A subsequent road user in the event of a wake-up call may not make a mark on the crashed vehicle, for example as a result of reduced visibility, ground, heavy precipitation, fog, mixed sunlight or the like; factors that in themselves also increase the probability of a traffic accident.

Dokument US20050030224 visar en kraschsensor hos ett fordon innefattande en mottaga- re for Global Positioning System (GPS). GPS mottagarenn detekterar bland annat hastigheten och huruvida fordonet avviker fran den tankta hastigheten. Om hastigheten avvikit kan en automatisk nodsignal tradlost skickas ut. Losningen enligt detta dokument är base-rat pa att fordonet har en krocksensor i kombination med att fordonet avviker fran en i forvag planerad hastighet. En nackdel med denna losning är att krocksensorn kanske inte 10 utloses vid en avakning av vagen med ett tungt fordon, som redan papekats. En annan nackdel ar att falsklarm riskerar att utlOsas, da fordonet kanske inte kan halla planerad hastighet till foljd av diverse oplanerade handelser som inte är att betrakta som olycka, exempelvis kobildning pa vagen, oplanerat stopp, punktering, sankning av hastigheten pa grund av nedsatt sikt/ dimma, halt vaglag, vagarbete, brooppning eller liknande, och foraren har- vid tvingas g6ra en kraftig inbromsning. Document US20050030224 shows a crash sensor of a vehicle including a receiver for the Global Positioning System (GPS). The GPS receiver detects, among other things, the speed and whether the vehicle deviates from the refueling speed. If the speed has deviated, an automatic node signal can be sent wirelessly. The unloading according to this document is based on the vehicle having a crash sensor in combination with the vehicle deviating from a pre-planned speed. A disadvantage of this unloading is that the crash sensor may not be triggered during a wake-up call with a heavy vehicle, which has already been parked. Another disadvantage is that false alarms risk being triggered, as the vehicle may not be able to maintain the planned speed as a result of various unplanned actions that are not considered an accident, such as cow formation on the road, unplanned stop, puncture, slowing down due to reduced visibility / fog, slippery road conditions, road work, bridge opening or the like, and the driver is thereby forced to make a sharp deceleration.

Dokument CN202380835 beskriver en metod och ett system som automatiskt kan larma nar ett fordon rakat ut for en olycka. Systemet innefattar en GPS och om det noteras att fordonet avviker fran en rutt larmas polisen. Syftet med denna losning Or att larma polisen am nagon kapar eller stjaler ett fordon, inte att detektera att en trafikolycka intraffat med fordonet och larma en larmcentral till fOljd av detta. Document CN202380835 describes a method and system that can automatically alert when a vehicle is shaved off in an accident. The system includes a GPS and if it is noted that the vehicle deviates from a route, the police are alerted. The purpose of this solution is to alert the police if someone hijacks or steals a vehicle, not to detect that a traffic accident has occurred with the vehicle and to alert an alarm center as a result.

Dokument US20030171939 visar en metod f6r att overvaka transport av farligt gods innefattande en GPS. Om fordonet avviker fran fardrutten eller narmar sig en myndighets- byggnad eller liknande skyddsobjekt kommer det automatiskt aft skickas ett larm. Syftet med denna metod Or att fOrhindra terroristattentat av 9/11-typ etc., med ett fordon, inte att detektera och larma da fordonet drabbats av en trafikolycka. Document US20030171939 discloses a method for monitoring the transport of dangerous goods including a GPS. If the vehicle deviates from the route or approaches an official building or similar protected object, an alarm will automatically be sent. The purpose of this method is to prevent terrorist attacks of the 9/11 type, etc., with a vehicle, not to detect and alert when the vehicle has been involved in a traffic accident.

Dokument US6178379 beskriver en metod for att overvaka ett navigationssystem genom att anvanda avvikelser som kan erhallas fran exempelvis en GPS. Navigationssensorn Or programmerad med onskad bana och kalkylerar darefter hur mycket fordonet avviker fran den onskade banan. Om det avviks for mycket kommer ett larm att ga som uppmarksammar foraren pa att en avvikelse har gjorts fran den planerade rutten. Fordonet i detta dokument Or ett flygplan. Ayen en styrsignal kan haryid genereras for att aterborda fordo- net till den planerade rutten. Denna losning avser inte att detektera en trafikolycka som fordonet gjort. 2 537 932 Det kan konstateras att mycket annu aterstar att Ora for att forbattra sakerheten i ett for-don. Document US6178379 describes a method for monitoring a navigation system by using deviations that can be obtained from, for example, a GPS. The navigation sensor Or is programmed with the desired trajectory and then calculates how much the vehicle deviates from the desired trajectory. If there is too much deviation, an alarm will sound to alert the driver that a deviation has been made from the planned route. The vehicle in this document Or an airplane. Ay a control signal can haryid be generated to return the vehicle to the planned route. This solution is not intended to detect a traffic accident caused by the vehicle. 2,537,932 It can be stated that much remains to be done to improve the safety of a vehicle.

SAMMANFATTNING Det är darfor en malsattning med denna uppfinning att kunna losa atminstone nagot av ovan angivna problem och forbattra forfarandet vid larmning i samband med en fordonsolycka och darmed uppna en forbattring av fordonet. SUMMARY It is therefore an object of this invention to be able to solve at least some of the above problems and to improve the procedure in the event of an alarm in connection with a vehicle accident and thereby achieve an improvement of the vehicle.

Enligt en forsta aspekt av uppfinningen uppnas denna malsattning av ett forfarande for 10 larmning da ett fordon hamnat utanfor trafikerbart omrade. Forfarandet innefattar faststallande av fordonets position med en positionsbestammande enhet genom satellitbaserad positionering. Vidare innefattar forfarandet aven ett konstaterande av att fordonet befinner sig utanfor trafikerbart omrade genom att mappa den faststallda fordonspositionen med kartdata dar vane position är definierad som tillhorigt endera trafikerbart omrade eller otra- fikerbart omrade. Forfarandet innefattar dessutom aven ett utlosande av olyckslarm, da fordonet konstateras befinna sig utanfor trafikerbart omrade. According to a first aspect of the invention, this targeting is achieved by a method of alarm when a vehicle ends up outside a traffic area. The method comprises determining the position of the vehicle with a position determining unit by satellite-based positioning. Furthermore, the method also comprises a determination that the vehicle is outside a traffic area by mapping the determined vehicle position with map data where the habitual position is defined as belonging to either a traffic area or a non-traffic area. The method also also includes the triggering of an accident alarm, as the vehicle is found to be outside a traffic area.

Enligt en andra aspekt av uppfinningen uppnas denna malsattning av en berakningsenhet, anordnad for larmning da ett fordon hamnat utanfor trafikerbart omrade. Berakningsenhe- ten innefattar en processorkrets, anordnad att ta emot en positionsbestamning for fordonet fran en positioneringsenhet innefattad i fordonet. Vidare är processorkretsen aven anordnad att konstatera att fordonet befinner sig utanfor trafikerbart omrade genom att mappa fordonspositionen med kartdata dar vane position an definierad som tillhorigt endera trafikerbart omrade eller otrafikerbart omrade. Berakningsenheten är vidare dessutom anord- nad att utlosa ett olyckslarm, da fordonet konstateras befinna sig utanfor trafikerbart omrade. According to a second aspect of the invention, this grinding is achieved by a calculating unit, arranged for alarm when a vehicle ends up outside a traffic area. The calculating unit comprises a processor circuit, arranged to receive a position determination for the vehicle from a positioning unit included in the vehicle. Furthermore, the processor circuit is also arranged to determine that the vehicle is outside the traffic area by mapping the vehicle position with map data where the habit position is defined as belonging to either a traffic area or a non-traffic area. The reconnaissance unit is also arranged to trigger an accident alarm, as the vehicle is found to be outside a traffic area.

Genom att definiera kartdata innefattande olika geografiska positioner som trafikerbart omrade respektive otrafikerbart omrade; faststalla ett fordons aktuella position samt jamfora fordonets geografiska position med denna kartdata och utlosa ett olyckslarm da fordonet befinner sig utanfor trafikerbart omrade kan ett olyckslarm genereras da fordonet exempelvis Icor av vagbanan, utan vidare aktiv insats av fordonets forare. Harigenom kan ett larm genereras och skickas till en larmcentral Oven om -Waren Or oformogen att sjalv larma, vilket kan vara livsavgorande i en nodsituation. Harigenom uppnas ett sakrare forfarande for larmning vid en olycka, och ett for foraren sakrare fordon. 3 537 932 Andra fordelar och ytterligare nya sat-drag kommer att framg5 fr5n foljande detaljerade beskrivning. By defining map data including different geographical positions as trafficable area and non-trafficable area, respectively; determine a vehicle's current position and compare the vehicle's geographical position with this map data and trigger an accident alarm when the vehicle is outside a traffic area, an accident alarm can be generated when the vehicle, for example Icor off the lane, without further active action by the vehicle's driver. As a result, an alarm can be generated and sent to an alarm center in addition to -Waren Or incapable of sounding the alarm itself, which can be vital in an emergency situation. This results in a safer procedure for alarm in the event of an accident, and a vehicle that is safer for the driver. 3,537,932 Other advantages and additional features will be apparent from the following detailed description.

Figur 1A visar ett fordon 100, anpassat for motordrivet framforande i bland annat en forsta fardriktning 105. Exempelvis, men inte nodvandigtvis, kan fordonet 100 vara ett lastfordon, en buss, eller utgoras av n5gon av de tidigare uppraknade typerna av fordon, eller liknande landbaserat fortskaffningsmedel. Figure 1A shows a vehicle 100, adapted for motorized driving in, inter alia, a first direction of travel 105. For example, but not necessarily, the vehicle 100 may be a truck, a bus, or be composed of any of the previously listed types of vehicles, or the like land-based means of subsistence.

Fordonet 100 innefattar en positionsbestammande enhet 110. Denna positionsbestammande enhet 110 kan vara anordnad att faststalla fordonets geografiska position, baserat p5 ett system for satellitnavigering s5som exempelvis Navigation Signal Timing and Rang- 4 537 932 ing (Navstar) Global Positioning System (GPS), Differentiell GPS (DGPS), Galileo, GLONASS, eller liknande. The vehicle 100 includes a position determining unit 110. This position determining unit 110 may be arranged to determine the geographical position of the vehicle, based on a satellite navigation system such as Navigation Signal Timing and Ranking (Navstar) Global Positioning System (GPS), Differential GPS (DGPS), Galileo, GLONASS, or similar.

Positionsbestamning baserat pa satellitnavigering bygger pa avstandsmatning med triangulering fran ett antal satelliter 120-1, 120-2, 120-3, 120-4. Satelliterna 120-1, 120-2, 120-3, 120-4 skickar kontinuerligt ut information om tid och datum (exempelvis i kodad form), identitet (vilken satellit 120-1, 120-2, 120-3, 120-4 som sander), status samt uppgifter om var satelliten 120-1, 120-2, 120-3, 120-4 befinner sig vid vane given tidpunkt. GPS satelliterna 120-1, 120-2, 120-3, 120-4 skickar information kodad med kodatskillnad, ex-10 empelvis baserat pa Code Division Multiple Access (CDMA). Harigenom kan information fran en individuell satellit 120-1, 120-2, 120-3, 120-4 sarskiljas fran de Ovrigas information, baserat pa en unik kod for vane respektive satellit 120-1, 120-2, 120-3, 120-4. Denna utskickade information kan sedan tas emot av en harfor anpassad GPS-mottagare, sasom exempelvis den positionsbestammande enheten 110. Position determination based on satellite navigation is based on distance feeding with triangulation from a number of satellites 120-1, 120-2, 120-3, 120-4. The satellites 120-1, 120-2, 120-3, 120-4 continuously send out information about time and date (for example in coded form), identity (which satellite 120-1, 120-2, 120-3, 120-4 as sander), status and information about where the satellite 120-1, 120-2, 120-3, 120-4 are at the usual time. The GPS satellites 120-1, 120-2, 120-3, 120-4 send information coded with coded difference, for example based on Code Division Multiple Access (CDMA). In this way, information from an individual satellite 120-1, 120-2, 120-3, 120-4 can be distinguished from the Information of the Others, based on a unique code of habit respectively satellite 120-1, 120-2, 120-3, 120 -4. This transmitted information can then be received by a specially adapted GPS receiver, such as the position determining unit 110.

Avstandsmatningen gar till sa att den positionsbestammande enheten 110 mater skillnaden i tid det tar for vane respektive satellitsignal att na den positionsbestammande enheten 110. Eftersom dessa signaler fardas med ljusets hastighet gar det att rakna ut hur langt det är till respektive satellit 120-1, 120-2, 120-3, 120-4. Genom att satelliternas positioner är kanda, da de kontinuerligt overvakas av cirka 15-30 markstationer placerade i huvudsak langsmed och i narheten av jordens ekvator, sa gar det sedan ocksa att rakna ut var man befinner sig, latitud och longitud nar man har faststallt avstandet till minst tre satelliter 11, 120-2, 120-3, 120-4 genom triangulering. For bestamning av altituden kan signaler fran atminstone fyra satelliter 120-1, 120-2, 120-3, 120-4 anvandas enligt vissa ut-foringsformer. The distance feed is done so that the position determining unit 110 feeds the difference in time it takes for each satellite signal to reach the position determining unit 110. Since these signals travel at the speed of light, it is possible to find out how far it is to each satellite 120-1, 120 -2, 120-3, 120-4. Because the positions of the satellites are known, as they are continuously monitored by about 15-30 ground stations located mainly along and near the Earth's equator, it is then also possible to unravel where you are, latitude and longitude when you have determined the distance to at least three satellites 11, 120-2, 120-3, 120-4 by triangulation. To determine the altitude, signals from at least four satellites 120-1, 120-2, 120-3, 120-4 may be used according to certain embodiments.

Vidare innefattar fordonet 100 en sandare 130, anordnad for tradlos kommunikation. Sadan tradlos kommunikation kan vara baserat pa exempelvis nagon av foljande teknologier: Global System for Mobile Communications (GSM), Enhanced Data Rates for GSM Evolution (EDGE), Universal Mobile Telecommunications System (UMTS), Code Division Ac- cess (CDMA), (CDMA 2000), Time Division Synchronous CDMA (TD-SCDMA), Long Term Evolution (LTE), LTE-Advanced; Wireless Fidelity (Wi-Fi), definierat av Institute of Electrical and Electronics Engineers (IEEE) standarder 802.11 a, ac, b, g och/ eller n, Internet Protocol (IP), Bluetooth och/ eller Near Field Communication, (NFC), eller liknande kommunikationsteknologi enligt olika utforingsformer med en larmcentral 140, eventuellt via en basstation eller liknande. 537 932 Larmcentralen 140 kan utgoras av en telefoncentral anordnad att ta emot nOdsamtal som beror exempelvis polis, ambulans, raddningstjanst, jourhavande prast, fjallraddning, sjoraddning, och liknande samhallstjanster. Operatoren i larmcentralen 140 kan sedan vid mottaget samtal i sin tur larma och dirigera ratt hjalpinsats beroende pa den specifika situa- tionen. Vidare kan larmcentralen 140 inga i det europeiska samarbetet e-call. Larmcentralen 140 kan anropas via olika telefonnummer i olika lander, sasom exempelvis 112; 90000; 911; 999; 110; 118; 091; 150; 119 etc. i olika lander. e-Call är en europeisk tjanst for elektroniska nodanrop fran fordon 100 till en larmcentral 10 140. Nar fordonet 100 rakar ut for en olycka kan fordonet 100 automatiskt skicka sin geografiska position till larmcentralen 140. Fordonet 100 upprattar en fOrbindelse med hjalp av den inbyggda sandaren 130 och kan exempelvis forst skicka ett kort datameddelande och sedan exempelvis uppratta en talforbindelse med larmcentralen 140. Furthermore, the vehicle 100 comprises a sander 130, arranged for wireless communication. Such wireless communication may be based on, for example, any of the following technologies: Global System for Mobile Communications (GSM), Enhanced Data Rates for GSM Evolution (EDGE), Universal Mobile Telecommunications System (UMTS), Code Division Access (CDMA), ( CDMA 2000), Time Division Synchronous CDMA (TD-SCDMA), Long Term Evolution (LTE), LTE-Advanced; Wireless Fidelity (Wi-Fi), defined by the Institute of Electrical and Electronics Engineers (IEEE) standards 802.11 a, ac, b, g and / or n, Internet Protocol (IP), Bluetooth and / or Near Field Communication, (NFC) , or similar communication technology according to different embodiments with an alarm center 140, possibly via a base station or the like. 537 932 The alarm center 140 can be constituted by a telephone exchange arranged to receive emergency calls which depend on, for example, the police, ambulance, rescue service, on-call pastor, mountain rescue, sea rescue, and similar community services. The operator in the alarm center 140 can then, when the call is received, in turn alert and direct the right auxiliary response depending on the specific situation. Furthermore, the alarm center 140 can not e-call in the European cooperation. The alarm center 140 can be called via different telephone numbers in different countries, such as 112; 90000; 911; 999; 110; 118; 091; 150; 119 etc. in different countries. e-Call is a European service for electronic node calls from vehicle 100 to an alarm center 10 140. When the vehicle 100 shaves for an accident, the vehicle 100 can automatically send its geographical position to the alarm center 140. The vehicle 100 establishes a connection using the built-in transmitter 130 and can, for example, first send a short data message and then, for example, establish a voice connection with the alarm center 140.

Vidare kan fordonet 100 och/ eller larmcentralen 140 fa' atkomst till kartdata, i synnerhet kartdata relaterad till den aktuella faststallda positionen pa fordonet 100, fran en fordonsextern kartdatabas 150. Denna kartdatabas 150 kan vara tillganglig over ett tradbundet eller tradlost granssnitt enligt olika utforingsformer. Enligt en utforingsform av uppfinningen är vane position i denna kartdata innefattad i kartdatabasen 150, definierad som tillhorigt en- dera trafikerbart omrade eller otrafikerbart omrade. Denna kartdata i kartdatabasen 1kan vara kontinuerligt uppdaterad, eller uppdateras med ett visst forutbestamt tidsintervall, sasom exempelvis minst en gang i timmen; minst en gang om dagen; minst en gang i veckan; minst en gang i manaden; minst en gang om aret, eller liknande tidsintervall. Furthermore, the vehicle 100 and / or the control center 140 can access map data, in particular map data related to the current determined position on the vehicle 100, from an external vehicle map database 150. This map database 150 may be accessible over a wired or wireless interface according to various embodiments. According to an embodiment of the invention, the habitual position in this map data is included in the map database 150, defined as belonging to either a traffic area or a non-traffic area. This map data in the map database 1 can be continuously updated, or updated with a certain predetermined time interval, such as at least once an hour; at least once a day; at least once a week; at least once a month; at least once a year, or similar time intervals.

Den positionsbestammande enheten 110 i fordonet 100 faststaller fordonets geografiska position. Denna positionsbestamning kan goras kontinuerligt med ett visst forutbestamt eller konfigurerbart tidsintervall enligt olika utforingsformer. Alternativt kan sadan positionsbestamning utlosas av en intraffad handelse, som exempelvis att fordonets hastighet underskrider en viss hastighet, exempelvis 10 km/ h; att en krockkudde utloses i fordonet 100; att fordonet 100 har retarderat/ decelererat/ inbromsat med en hastighet overskridande ett gransvarde; att en krocksensor har utlosts; att fordonets forare initierar en positionsbestamning eller liknande handelse. The position determining unit 110 in the vehicle 100 determines the geographical position of the vehicle. This position determination can be done continuously with a certain predetermined or configurable time interval according to different embodiments. Alternatively, such position determination can be triggered by an incident occurred, such as that the vehicle's speed falls below a certain speed, for example 10 km / h; that an airbag is deployed in the vehicle 100; that the vehicle 100 has decelerated / decelerated / decelerated at a speed exceeding a spruce value; that a crash sensor has been triggered; that the driver of the vehicle initiates a position determination or similar action.

Denna faststallda position pa fordonet 100 kan sedan mappas mot kartdata dar varje position är definierad som tillhorigt endera trafikerbart omrade eller otrafikerbart omrade. Enligt vissa utfOringsformer kan en sadan mappning goras i fordonet 100, vilket har fordelen att sadan bedomning gar snabbt dá ingen kommunikation med extern enhet behover goras. I 6 537 932 andra utforingsformer kan fordonet 100 istallet skicka ut sin faststallda position till en extern enhet, exempelvis larmcentralen 140 eller nagon annan godtycklig enhet. En fordel harmed är att fordonet 100, eller snarare en berakningsenhet i fordonet 100, vid en olycka kanske är sa skadad att namnda mappning och bedomning inte är mojlig att utfora i fordonet 100. This determined position on the vehicle 100 can then be mapped to map data where each position is defined as belonging to either a traffic area or a non-traffic area. According to certain embodiments, such a mapping can be done in the vehicle 100, which has the advantage that such an assessment is done quickly when no communication with an external unit needs to be done. In 6,537,932 other embodiments, the vehicle 100 may instead send its fixed position to an external unit, for example the alarm center 140 or any other unit. An advantage here is that the vehicle 100, or rather a calculating unit in the vehicle 100, in an accident may be so damaged that said mapping and judging is not possible to perform in the vehicle 100.

Att Ora sadan berakning i en fordonsextern enhet kan darfor utgora en mer robust alternativ losning. That Ora such a calculation in a vehicle external unit can therefore constitute a more robust alternative solution.

Om det harvid konstateras att fordonet 100 befinner sig utanfor trafikerbart omrade, utloses ett olyckslarm. Sadant olyckslarm kan innefatta att en radiosignal skickas med sandaren 10 130, for att tas emot av larmcentralen 140. Denna radiosignal kan aven innefatta information utOver larmsignalen, sasom exempelvis information som avser: fordonets position, identifikation av fordonet 100, fordonets fardriktning, tidpunkt for larmet, fordonsbeskrivning, aktiverade sensorer i fordonet 100, landskod, information om fordonet 100 innefattar farlig last, antal passagerare i fordonet 100, eller liknande information. If it is found that the vehicle 100 is outside a traffic area, an accident alarm is triggered. Such an accident alarm may include that a radio signal be sent with the transmitter 130, to be received by the alarm center 140. This radio signal may also include information beyond the alarm signal, such as information relating to: vehicle position, vehicle identification 100, vehicle direction of travel, time of alarm , vehicle description, activated sensors in the vehicle 100, country code, information about the vehicle 100 includes dangerous cargo, number of passengers in the vehicle 100, or similar information.

I vissa alternativa utforingsformer kan det utlOsta olyckslarmet aven innefatta att en larmanordning pa eller i fordonet 100 aktiveras, exempelvis att varningsblinkers eller annan liknande intermittent eller kontinuerlig belysning aktiveras pa fordonet 100, for att varna omgivande trafikanter for olyckan och pakalla deras uppmarksamhet. Sadan alternativ larmanordning pa fordonet 100 kan i vissa utforingsformer aven innefatta ljudsignal, exempelvis genom att fordonets signalhorn aktiveras. Harigenom mojliggors att fordonets forare kan fa direkt hjalp, forsta hjalpen, av en eventuell medtrafikant, utan att utryckningsfordon behover invantas. Vidare kan en sadan larmanordning med ljus och/ eller ljud pa fordonet 100 aven underlatta for ett annalkande utryckningsfordon att hitta fram till det forolyckade fordonet 100, vilket kan reducera vantetiden for fordonets forare och minskar risken att utryckningsfordonet passerar forbi det forolyckade fordonet 100 utan att upptacka det. In certain alternative embodiments, the triggered alarm may also include activating an alarm device on or in the vehicle 100, such as activating hazard warning lights or other similar intermittent or continuous lighting on the vehicle 100, to alert surrounding road users to the accident and alert them. Such an alternative alarm device on the vehicle 100 may in certain embodiments also include an audible signal, for example by activating the vehicle's horn. This makes it possible for the driver of the vehicle to receive direct assistance, first aid, from a possible fellow road user, without the need for emergency vehicles. Furthermore, such an alarm device with light and / or sound on the vehicle 100 can also make it easier for an approaching emergency vehicle to find the crashed vehicle 100, which can reduce the waiting time of the vehicle driver and reduce the risk of the emergency vehicle passing the crashed vehicle 100 without detecting the.

Figur 1B visar ett fordon 100, exempelvis fordonet 100 som tidigare visats i figur 1A, men betraktat ur ett forarperspektiv. Figure 1B shows a vehicle 100, for example the vehicle 100 previously shown in Figure 1A, but viewed from a driver's perspective.

I en alternativ utforingsform kan fordonet 100 innefatta en berakningsenhet 160. Denna berakningsenhet 160 kan kommunicera med den positionsbestammande enheten 110 i fordonet 100, exempelvis via fordonets kommunikationsbuss, vilken kan utgoras av en eller flera av en kabel; en databuss, sasom en CAN-buss (Controller Area Network bus), en MOST-buss (Media Oriented Systems Transport), eller nagon annan busskonfiguration. 7 537 932 Berakningsenhet 160 kan aven, eller alternativt, vara anordnad for tradlOs kommunikation over ett tradlost granssnitt enligt vissa utforingsformer, exempelvis flagon av de ovan uppraknade tradlosa granssnitten. In an alternative embodiment, the vehicle 100 may include a calculating unit 160. This calculating unit 160 may communicate with the position determining unit 110 in the vehicle 100, for example via the vehicle communication bus, which may be one or more of a cable; a data bus, such as a CAN bus (Controller Area Network bus), a MOST bus (Media Oriented Systems Transport), or any other bus configuration. 7 537 932 Calculation unit 160 may also, or alternatively, be arranged for wireless communication over a wireless interface according to certain embodiments, for example flakes of the wireless interfaces listed above.

Vidare är berakningsenhet 160 anordnad aft ha tillgang till kartdata, i synnerhet kartdata relaterad till den aktuella faststallda positionen pa fordonet 100, fran den fordonsexterna kartdatabasen 150. Denna kartdatabas 150 kan vara tillganglig over ett tradbundet eller tradlost granssnitt enligt olika utforingsformer. Enligt en utforingsform av uppfinningen är vane position i denna kartdata innefattad i kartdatabasen 150, definierad som tillhorigt en- 10 dera trafikerbart omrade eller otrafikerbart omrade. Enligt vissa utforingsformer kan berakningsenheten 160 ha en tillgang till en lokal databas eller minnesenhet i fordonet 100, dar kartdata nedladdas, exempelvis fran den fordonsexterna kartdatabasen 150. Sadan nedladdning kan triggas exempelvis av aktuell faststalld position, av -Waren, eller efter en viss korstracka eller liknande. Exempelvis kan sadan nedladdning goras av en delmangd av den kartdata som finns i den fordonsexterna kartdatabasen 150, relaterad till fordonets aktuella position. Harigenom kan kartdata relaterad till en viss region, exempelvis Stockholms Ian, nedladdas till den lokala databasen eller minnesenhet i fordonet 100, da fordo-net 100 konstateras befinna sig vid gransen till Stockholms Ian och pa vag aft fardas in i detsamma, for aft nu bara namna ett exempel. Furthermore, calculation unit 160 is arranged to have access to map data, in particular map data related to the current determined position on the vehicle 100, from the vehicle external map database 150. This map database 150 can be accessible over a wired or wireless interface according to different embodiments. According to an embodiment of the invention, habitual position in this map data is included in the map database 150, defined as belonging to either a traffic area or a non-traffic area. According to certain embodiments, the calculation unit 160 may have access to a local database or memory unit in the vehicle 100, where map data is downloaded, for example from the vehicle external map database 150. Such download may be triggered, for example, by the current fixed position, by -Waren, or after a certain crossover or similar. For example, such a download may be made from a subset of the map data contained in the vehicle external map database 150, related to the current position of the vehicle. As a result, map data related to a certain region, for example the Stockholm Ian, can be downloaded to the local database or memory unit in the vehicle 100, as the vehicle 100 is found to be at the border of the Stockholm Ian and on the way to be driven into the same, for now only name an example.

En fOrdel med att nedladda kartdata forknippad med fordonets position kontinuerligt, eller med visst tidsintervall, är aft berakningsenheten 160 dá far tillgang till relevant och aktuell kartdata. Harigenom kan man undvika falska larm till -WO av exempelvis en vagutbyggnad eller liknande. An advantage of downloading map data associated with the vehicle's position continuously, or with a certain time interval, is that the calculation unit 160 then has access to relevant and current map data. In this way, false alarms to -WO of, for example, a wagon extension or the like can be avoided.

Berakningsenheten 160 kan vidare mappa den faststallda positionen pa fordonet 100 mot kartdata dar varje position är definierad som tillhorigt endera trafikerbart omrade eller otrafikerbart omrade. Om fordonet 100 konstateras befinna sig pa en position definierat som otrafikerbart omrade, är berakningsenheten 160 anordnad aft utlosa ett olyckslarm. Sadant olyckslarm kan innefatta aft en radiosignal skickas med sandaren 130, for att tas emot av larmcentralen 140. The calibration unit 160 may further map the determined position of the vehicle 100 to map data where each position is defined as belonging to either a traffic area or a non-traffic area. If the vehicle 100 is found to be in a position defined as non-trafficable area, the calculating unit 160 is arranged to trigger an accident alarm. Such an accident alarm may include a radio signal sent with the transmitter 130, to be received by the alarm center 140.

En fordel med att ha berakningsenheten 160 i fordonet 100 och aven ha en lokal databas/ minne i fordonet 100 och genomfora forfarandet i berakningsenheten 160 i fordonet 100 är aft eventuell tidsfordrojning till foljd av dataskickning minskas. Harigenom erhalls en snabbare och robustare process som är mindre beroende av eventuella brister och storningar i 8 537 932 det tradlOsa granssnittet, an om man har berakningsenheten 160 placerad utanfor fordonet 100. An advantage of having the calculation unit 160 in the vehicle 100 and also having a local database / memory in the vehicle 100 and carrying out the procedure in the calculation unit 160 in the vehicle 100 is that any time delay due to data transmission is reduced. This results in a faster and more robust process that is less dependent on possible deficiencies and disturbances in the wireless interface, than if the calculating unit 160 is located outside the vehicle 100.

Figur 2 illustrerar hur kartdata definieras som tillhorigt endera trafikerbart omrade 2eller otrafikerbart omrade 220. Det trafikerbara omradet 210 innefattar vasentligen den korbara delen av en vag, inklusive korbana, rastplats, tunnel, bro, rondell, bilfarja, farjelager, fordonsmotesplats, parkeringsplats, tankstationsomrade, fordonsverkstad, kontrollplats for tull, polis och annan myndighet, sidoficka, avfart, Wart, uppfart, skaftvag pa tomt och liknande korbar yta i anslutning till vagens korbana. Figure 2 illustrates how map data is defined as belonging to either a traffic area 2 or a non-traffic area 220. The traffic area 210 essentially comprises the crossable part of a wagon, including the railway, rest area, tunnel, bridge, roundabout, car ferry, ferry depot, vehicle meeting place, car park area, petrol station area, vehicle workshop, checkpoint for customs, police and other authorities, side pocket, exit, Wart, driveway, shaft carriage on site and similar curable surface adjacent to the carriage's carriageway.

Det otrafikerbara omradet 220 innefattar ovriga delar av landskapet som inte kan karakteriseras som trafikerbart omrade 210, som exempelvis vagdike, natur, jordbrukslandskap, vattendrag, byggnader, oasfalterad yta, byggarbetsplats och liknande landskapstyper som inte är avsedda for fordonstrafik eller fordonsparkering. The non-traffic area 220 includes other parts of the landscape that cannot be characterized as traffic area 210, such as road ditches, nature, agricultural landscapes, watercourses, buildings, unpaved surface, construction site and similar landscape types that are not intended for vehicle traffic or vehicle parking.

Enligt vissa utforingsformer kan det trafikerbara omradet 210 respektive det otrafikerbara omradet 220 definieras baserat pa fordonets fardriktning och/ eller vagtyp, sá att korbanan pa fardvagens Viagra sida, betraktat i fordonets fardriktning, definieras som trafikerbart omrade 210 medan den motsatta sidan, det vill saga fardvagens vanstra sida betraktat i for- donets fardriktning, definieras som otrafikerbart omrade 220. Harigenom kan man definiera en situation dar fordonet 100 kOrt over fardvagens mittlinje som en situation dar fordonet 100 hamnat utanfor trafikerbart omrade 210. Enligt vissa utforingsformer kan en sadan definition goras pa vagar dar filerna i respektive fardriktning är atskiljda, exempelvis av en vajer, stolpar, vagracke eller liknande hinder, men daremot inte pa andra typer av vagar. According to certain embodiments, the traffic area 210 and the non-traffic area 220 can be defined based on the vehicle's direction of travel and / or type of vehicle, so that the lane on the vehicle's Viagra side, viewed in the vehicle's direction, is defined as traffic area 210 while the opposite side, i.e. the vehicle's left side viewed in the direction of travel of the vehicle, is defined as non-traffic area 220. Thereby one can define a situation where the vehicle is 100 km above the center line of the carriageway as a situation where the vehicle 100 ends up outside traffic area 210. According to some embodiments such a definition can be made where the lanes in each direction of travel are separated, for example by a wire, poles, carriage rail or similar obstacles, but not on other types of carriages.

Harigenom mojliggors ett tillfalligt overskridande av fardvagens mittlinje, exempelvis vid omkOrning, utan att detta utlOser ett olyckslarm, enligt vissa utforingsformer. This makes it possible to temporarily exceed the center line of the carriage, for example when overtaking, without this triggering an accident alarm, according to certain embodiments.

I detta illustrativa exempel i figur 2 askadliggors fordonets position i kartdatat, exempelvis pa en bildskarm 200. Detta är dock ingen nodvandighet eller forutsattning for uppfinningen, eller ens en egentlig del av densamma enligt flertalet utforingsformer; snarare avser denna figur att illustrera ett exempel pa vad som kan avses med trafikerbart miracle 210 respektive otrafikerbart omrade 220 i vissa utforingsformer. In this illustrative example in Figure 2, the position of the vehicle is mapped in the map data, for example on a monitor 200. However, this is not a necessity or prerequisite for the invention, or even an actual part of it according to most embodiments; rather, this figure is intended to illustrate an example of what may be meant by trafficable miracle 210 and non-trafficable area 220, respectively, in certain embodiments.

Figur 3 visar tva principiella strukturkoncept enligt olika utforingsformer. I en forsta utforingsform innefattar fordonet 100-1 en positionsbestammande enhet 110 och en berakningsenhet 160. Den positionsbestammande enheten 110 faststaller fordonets position och meddelar denna till berakningsenheten 160, aven den belagen i fordonet 100-1. Berak- 9 537 932 ningsenheten 160 mappar fordonets faststallda position som mottagits fran den positionsbestammande enheten 110 mot kartdata dar alla positioner är definierade som endera trafikerbart omrade 210 eller otrafikerbart omrade 220. Om fordonet 100-1 konstateras befinna sig utanfor trafikerbart omrade 210, triggar berakningsenheten 160 alstring och sandning av ett olyckslarm, exempelvis genom sandning av en tradlos signal via sandaren 130. Detta tradlosa olyckslarm skickas for att tas emot av en larmcentral 140-1, enligt en utforingsform. Figure 3 shows two basic structural concepts according to different embodiments. In a first embodiment, the vehicle 100-1 comprises a position determining unit 110 and a calculating unit 160. The position determining unit 110 determines the position of the vehicle and communicates this to the calculating unit 160, also the one covered in the vehicle 100-1. The tracking unit 160 maps the determined position of the vehicle received from the position determining unit 110 to map data where all positions are defined as either traffic area 210 or non-traffic area 220. If the vehicle 100-1 is found to be outside traffic area 210, the calculation unit triggers 160 generating and sanding an accident alarm, for example by sanding a wireless signal via the transmitter 130. This wireless accident alarm is sent to be received by an alarm center 140-1, according to an embodiment.

Enligt en andra utforingsform innefattar fordonet 100-2 en positionsbestammande enhet 110. Den positionsbestammande enheten 110 faststaller fordonets position och meddelar denna till en berakningsenhet 160, belagen i en andra utforingsform av larmcentralen 12. Denna berakningsenhet 160 kan sedan mappa fordonets faststallda position som mottagits fran den positionsbestammande enheten 110 mot kartdata dar alla positioner är definierade som endera trafikerbart omrade 210 eller otrafikerbart omrade 220. Om fordonet 100-2 konstateras befinna sig utanfor trafikerbart omr5de 210, triggar berakningsenheten 160 alstring och sandning av ett olyckslarm, exempelvis genom sandning av en tradbunden eller tradlos larmsignal, varvid en operator vid larmcentralen 140-2 uppmarksammas pa den uppkomna incidenten for fordonet 100-2. According to a second embodiment, the vehicle 100-2 comprises a position determining unit 110. The position determining unit 110 determines the position of the vehicle and communicates this to a calculation unit 160, located in a second embodiment of the alarm center 12. This calculation unit 160 can then map the determined position of the vehicle received from the position determining unit 110 against map data where all positions are defined as either traffic area 210 or non traffic area 220. If the vehicle 100-2 is found to be outside traffic area 210, the calculation unit 160 triggers the generation and sanding of an accident alarm, for example by sanding a wired or wireless alarm signal, whereby an operator at the alarm center 140-2 is alerted to the incident occurring for the vehicle 100-2.

Figur 4 illustrerar ett exempel pa utforingsform for uppfinningen. Flodesschemat i figur 4 5sk5dliggor ett forfarande 400 for larmning d5 ett fordon 100 hamnat utanfor trafikerbart omrade 210. Syftet med forfarandet 400 är att generera ett olyckslarm och darmed uppmarksamma en operator vid en larmcentral 140 p5 att fordonet 100 har hamnat utanfor trafikerbart omrade 210, exempelvis genom att ha kort i diket, kart ut p5 en aker eller lik- nande till -WA av en olyckshandelse i fordonet 100. Figure 4 illustrates an example of an embodiment of the invention. The flow chart in Figure 4 shows a procedure 400 for alarming d5 a vehicle 100 ending up outside traffic area 210. The purpose of method 400 is to generate an accident alarm and thereby alert an operator at an alarm center 140 p5 that the vehicle 100 has ended up outside traffic area 210, e.g. by having cards in the ditch, map out p5 an acre or similar to -WA of an accident in the vehicle 100.

For att p5 ett korrekt satt kunna detektera ett olyckstillbud och generera ett larm i fordonet 100 kan forfarandet 400 innefatta ett antal steg 401-404. Det bor dock observeras att vissa av de hat- beskrivna stegen bara innefattas i vissa alternativa utforingsformer av uppfin- ningen, s5som exempelvis steg 403. Vidare kan de beskrivna stegen 401-404 utforas i en nagot annorlunda kronologisk ordning an vad nummerordningen antyder och att vissa av dem kan utforas parallellt med varandra. Forfarandet 400 innefattar foljande steg: Steg 401 Fordonets position faststalls med en positionsbestammande enhet 110 genom satellitbaserad positionering. 537 932 S5dan satellitbaserad positionering kan innefatta exempelvis GPS, Navstar, DGPS, Galileo, GLONASS, eller liknande. In order to be able to correctly detect an accident and generate an alarm in the vehicle 100, the method 400 may comprise a number of steps 401-404. It should be noted, however, that some of the hate-described steps are included only in certain alternative embodiments of the invention, such as, for example, step 403. Furthermore, the described steps 401-404 may be performed in a slightly different chronological order from what the number order suggests and of them can be performed in parallel with each other. Method 400 includes the following steps: Step 401 The position of the vehicle is determined by a position determining unit 110 by satellite positioning. 537 932 Such satellite-based positioning may include, for example, GPS, Navstar, DGPS, Galileo, GLONASS, or the like.

Steg 402 Det konstateras aft fordonet 100 befinner sig utanfor trafikerbart omrade 210 genom aft mappa den faststallda 401 fordonspositionen med kartdata dar varje position ar definierad som tillhorigt endera trafikerbart omrade 210 eller otrafikerbart omrade 220 och konstatera aft fordonet 100 befinner sig utanfor trafikerbart omrade 210 d5 den faststallda 401 fordonspositionen befinner sig utanfor trafikerbart omrade 210. Step 402 It is determined that the vehicle 100 is outside the traffic area 210 by mapping the determined 401 vehicle position with map data where each position is defined as belonging to either the traffic area 210 or the non-traffic area 220 and finding that the vehicle 100 is outside the traffic area 210 d5 it the fixed 401 vehicle position is outside the trafficable area 210.

Steg 403 Detta forfarandesteg kan utforas i vissa, men inte nadvandigtvis samtliga utforingsformer av forfarandet 400. Step 403 This process step may be performed in some, but not necessarily all, embodiments of the procedure 400.

Eft sensormatvarde som p5visar aft fordonet 100 har drabbats av en trafikolycka detekteras. Sadant sensormatvarde kan exempelvis innefatta matvarde fran en, flera, samtliga eller en kombination av: accelerometer, krocksensor, krockkudde, strackningsmatare p5 sakerhetsbalte vid forarplats, och/ eller hastighetsmatare i fordonet 100, manuell indikation gjord av fordonets forare genom att intrycka en knapp eller liknande. After the sensor food value which indicates that the vehicle 100 has been hit by a traffic accident is detected. Such sensor feed values may, for example, include feed values from one, several, all or a combination of: accelerometer, crash sensor, airbag, tension feeder p5 safety belt at driver's seat, and / or speed feeder in vehicle 100, manual indication made by vehicle driver by pressing a button or the like .

Harigenom, genom aft samla in en eller fler ytterligare indikatorer p5 aft en trafikolycka intraffat kan risken for fellarm till foljd av exempelvis en bristfallig eller felaktig positionsbestamning av fordonet 100, undvikas. In this way, by collecting one or more additional indicators of a traffic accident that has occurred, the risk of false alarms as a result of, for example, a faulty or incorrect position determination of the vehicle 100, can be avoided.

Steg 404 D5 fordonet 100 konstateras 402 befinna sig utanfor trafikerbart omrade 210 utlOses ett olyckslarm.
