När bilar kan känna av väggreppet

LINKÖPING, Sverige, August 28, 2014 /PRNewswire/ --

NIRA Dynamics AB har utvecklat algoritmer som kan estimera det aktuella friktionsvärdet mellan vägen och ett fordons däck.

Erfarna förare läser av vägen med nästan alla sinnen: de ser, känner och till och med lyssnar på ljudet inne i kupén. De använder all den informationen för att uppskatta det nuvarande väggreppet och anpassar därefter sin hastighet givet sin långa erfarenhet.  

Tänk dig tanken om alla bilar skulle kunna ha en sådan erfaren andrepilot som kan hjälpa till i denna bedömning?

Att köra för fort eller att missbedöma väg och trafikförhållanden är fortfarande idag den mest vanliga orsaken till olyckor i trafiken. Dagens inbyggda assistanssystem kan känna igen vägskyltar och hjälpa föraren att inte överträda hastighetsbegränsningen. De flesta förare känner också till dagens halkvarnare som tänds när den omgivande temperaturen går ner mot fryspunkten. Dessa funktioner är steg i rätt riktning, men med algoritmerna från NIRA kan alla fordon idag ta ett större kliv och bli ännu smartare.

Ett typiskt exempel där NIRAs algoritmer kan användas är vid ett långt segment av olja på en kurvig väg. Detta kanske knappt är kännbart för en bilförare, men är en potentiell dödsfälla för motorcyklister till och med i låga farter. Om friktionsvärdet som beräknas med NIRAs algoritmer kommuniceras direkt eller till infrastruktur kan efterföljande trafikanter erhålla en varning innan det är för sent.  

Tittar man ännu längre in i framtiden så blir autonoma fordon antagligen inte verkligen utan att ha friktionsskattning när datorer slutligen tar över bilkörandet. Hur utmanande det i sig än är, kommer det inte att vara tillräckligt för nya bilar att känna igen andra fordon, fotgängare och föremål. Fordonet måste då även veta väggreppet för att fatta rätt beslut.

NIRA letar nu efter bilapplikationer och partners där denna teknik kan bli verklighet på vägen.

Bakgrund om företaget:  

NIRA Dynamics AB grundades 2001 och har en mer än 60 anställda, i huvudsak ingenjörer och testtekniker. Huvudkontoret ligger i Linköping, Sverige, men NIRA har även filialer i Shanghai och München i samarbete med IAV Automotive Engineering. Spetskompetensen hos NIRA ligger inom signalbehandling & sensor fusion och mjukvarubaserade assistansfunktioner. NIRAs huvudprodukt är TPI (Tire Pressure Indicator) som är ett världsledande indirekt däcktryckövervakningssystem.
