Autoliv Integrated Safety & Drowsy Drivers The Worldwide leader in Automotive Safety Systems 2007 Wake Up, Michigan! September 20 th 2007 PRIVATE/PROPRIETARY
Our vision is to substantially reduce traffic accidents, fatalities and injuries Our mission is to create, manufacture and sell state-of-the-art automotive safety systems AUTOLIV-0000/INITIALS/DATE/FILENAME - 2 PRIVATE/PROPRIETARY
Drowsy & Distracted Drivers • National Highway Traffic Safety Administration (NHTSA) estimates that approximately 100, 000 police-reported crashes annually (about 1. 5% of all crashes) involve drowsiness/fatigue as a principal causal factor • A conservative estimate of related fatalities is 1, 500 annually or 4% of all traffic crash fatalities. • At least 71, 000 people are injured in fall-asleep crashes each year. • NHTSA estimates these crashes represent $12. 5 billion in monetary losses each year.

Drowsy & Distracted Drivers Sleepiness leads to crashes because: • Slower reaction time • Reduced vigilance • Deficit’s in information processing AUTOLIV-0000/INITIALS/DATE/FILENAME - 4 PRIVATE/PROPRIETARY
NHTSA NCAP Proposal Investigate rating system for crash avoidance technologies • A step beyond Passive Safety only rating Primarily address the four most significant crash modes • Run off road – 27% MAIS 3+ injuries • Rear End – 19% of MAIS 3+ injuries • Lane change – 6% of MAIS 3+ injuries • Crossing path (intersection) – 30% of MAIS 3+ injuries Recognition of Active Safety Technology AUTOLIV-0000/INITIALS/DATE/FILENAME - 5 PRIVATE/PROPRIETARY
Integrated Safety • Driver support & collision mitigation will drive • advanced sensor development, but…. The greatest opportunity for the future is driven by combining Active Safety Systems & Passive Safety Systems Passive Safety will still be the dominating system in saving lives for the foreseeable future AUTOLIV-0000/INITIALS/DATE/FILENAME - 6 PRIVATE/PROPRIETARY
Integrated Safety Chart Normal Driving Threatening situation Crash is nonavoidable Accident Passive Active Long Term Rescue Safety Golden Hour & Heal Reduction of Accident Occurrence Reduction of Accident Severity Reduction of Injury Severity & Fatality AUTOLIV-0000/INITIALS/DATE/FILENAME - 7 PRIVATE/PROPRIETARY Reduction of Injury Consequences
Integrated Safety Priorities • Maintain safe speed & distance • Stay in lane and avoid dangerous passing • • maneuvers Safely pass intersections Avoid collisions with vulnerable road users Reduce severity of accidents Improve occupant protection beyond current ratings and regulations AUTOLIV-0000/INITIALS/DATE/FILENAME - 8 PRIVATE/PROPRIETARY
Integrated Safety Sensing • How do we know we have an issue? • • Driver • Drowsiness, alcohol, attention to the road Vehicle • Lane Departure, collision warning, path estimation, GPS tracking, stability, closing velocity Actuation • What do we do about it? • • • Reduce driver workload/ increase awareness • Night Vision, Speed Sign Recognition, Intersection Awareness, Adaptive cruise control, Queue assist, blind spot detection, Stop & Go Warn driver – raise awareness of Drowsiness issue • HMI, buzzers, chimes, lights, haptic warning on seat belts, vibrating seat, vibrating steering wheel, pedal resistance Take action – vehicle control • Stability control, collision mitigation by braking, Safety System pre-trig AUTOLIV-0000/INITIALS/DATE/FILENAME - 9 PRIVATE/PROPRIETARY

NCAP Proposals Highlight Crash Avoidance Technologies to the consumer – what is the benefit? Crash Avoidance rating • • Option 1 – 1 grade for each technology adopted (e. g. C grade for 1 technology, B grade for 2 etc) Option 2 – Letter grade based on total points earned using assigned weighting (points) for each technology according to its overall effectiveness 3 Priority Technologies • • • ESC LDW Rear End Collision avoidance AUTOLIV-0000/INITIALS/DATE/FILENAME - 17 PRIVATE/PROPRIETARY
