1.3 million people are killedeachyearworldwide in road accidents • 50 million are injured • United Nations and the World Health Organization have launched in 2011 a • Decade of Action for Road Safety • In support of the Decade of Action, the FIA has launched the “FIA Action For Road Safety” • designed to harness FIA assets at the service of this important cause. • Europe : 40 000 killedeachyear • Same magnitude in Northamerica • Solutions for emerging countries or developed countries canbequitedifferent • The goal of thispresentationis to illustrate how connectedcar • cancontribute to road safety in developed countries. Target = zerofatality Connected Car - Safety
Evolution of fatalities in Europe Asymptotic behaviour Number of people killed in Europe per billion km • Bigimprovement in 35 years • An asymptot has been reached • Whichtechnologybreakthrough • in order to arrive at zerofatality ? Connected car canrealisethisbreakthrough Connected Car - Safety
AGENDA • A few facts about accident data analysis • Illustration on a few examples of why and how the connected car candrammaticallyenhance active safety • Conclusion • WARNINGS • The ideas I express here are based on personal engineering experience on active safety. • I have oftenuseddifferent sources and simplified a lot in order to be able to present basic ideas in a very short time. • Keep the ideas for furtherthinking • Don’tkeep the numbers or figures as an up to date reference. • This is not about autonomous car • Thoughthesesubjects have strong connections, autonomous car is a veryambitious program, an order of magnitude more complexthan the ideas I presenthere Connected Car - Safety

Efficiency of Safety Functions Using Connected Car • AutomaticBrakingFunctions • Usingonly on boardsensors : a few % of efficiency for fatalityreduction ( < 5%) • ~1/3 of fatalities arise due to frontal collisions • This shows the hugepotential of high levelautomaticbrakingfunctionsusingconnected car • Lateralshock • ~ 1/3 of fatalities • This shows the hugepotentialof connected car able to alert or avoidside collision • Loss of control situations • Current ESP systems have ~ 16% of efficiency to reducefatalities. • Enhanced ESP systemsusingconnected car and GPS couldprobably have the potential to raisesignificantlythisoverallefficiency. • All thesenumbers are rough estimates, and theyobviouslydon’taddeachother. Howevertheyillustrate the potential of connected car to reducefatalities. Connected Car - Safety
CONCLUSION • Connected Car, car 2 car and car to infrastucture communication can help developvery efficient safetyfunctionsthatcouldachieve the zerodeathtarget. • This « connectivity » couldbeextended to every road users, including pedestrians, motocyclists…. • Cost ? • It seemsthat the development of 4G and higher standards of communications couldsoonmakeit a no problem. • Moreoverthinking to the very high global costof road unsafety (Europe : 160 billion € 2% GNP) , there are ways to handlecost issues. • Connected car requires communication betweendifferent car brands Necessity of standards of communication and International agreements. • + Connected Car - Safety

About Connectivity Connected Car - Safety
Responsibility of driver / car ? • This question shouldbetreated as a public health question • Even if one system fails one time, on the global, the benefitishuge • Like for medicine, weshoulddefinesomequality and safety concept requirements for automaticsafetysystems to beapproved, based on highlylowprobabilityfailure occurrence. • We have to considerthat a car has possibilities to reactdynamicallymuchquicker and in a waythatis not accessible even for the best driver (e.g. possibilities of actions wheel per wheel, combinedwith anti-lock system..etc..) • Finallywhenwesaytodaythat the driver « drives » the car, weshouldn’tforgetthatitdoessothrough a chain of mechanic/electronicequipments and links thatcaneach have theirownfailures. So heis not in 100% control of his car, but 100%-probability of failure. At the end itis not so sure that the probability of failure in normal drive situations islowerthan the probability of failureachievablewithautomatic active safetysystems. At the end the situations are equivalent. Connected Car - Safety
