3 Reduction of crash fatalities Fatalities EU 25 52K 26K Airbag (1980) ESP (1995) ACC (2000) System integration CAPS Combined CAPS Active & Passive Safety esafety goal (EU): 50% fatality reduction

4 CAPS is Active Safety Accident mitigation e.g. ABS, ESP, VDM Passive Safety Injury reduction e.g. airbag, seatbelt tensioner Driver Assistance Assistance e.g. Adaptive Cruise Control (ACC) Communication Traffic information/ guidance e.g. navigation, display technology Vehicle movement sensing & control Crash sensing Occupant protection Surround sensing Vehicle communication 4

5 CAPS the route to enhanced driving safety Active Safety Driver Assistance Radar based systems Ultrasonic based systems Video based systems Vehicle stabilizing Brake functions CAPS Preventive information Coordinated interaction Added value functions Targets: Accident mitigation and reduced accident severity Vehicle dynamics Detection and sensing Occupant protection Pedestrian protection Navigation systems Display technology Car-to-x Passive Safety Communication 5

6 Selection of safety functions Predictive Safety Systems Active Safety Driver Assistance Vehicle stabilizing Brake functions Vehicle dynamics Radar based systems Ultrasonic based systems Video based systems PBA (Predictive Brake Assist) Adaptive Brake Assist (ABA) Automatic Brake Pre-fill (ABP) Reduced braking distance PCW (Predictive Collision Warning) PBA + driver warning (e.g. short brake pulse) PEB (Predictive Emergency Brake) PCW + automatic emergency braking before an inevitable collision 6

7 Selection of safety functions occupant protection Active Safety Vehicle stabilizing Brake functions Vehicle dynamics Passive Safety RoSe II (Roll-over Sensing) Earlier deployment of curtain airbags based on ESP sensor signals in roll-over situations EPCD (Early Pole Crash Detection) Earlier deployment of restraint devices in case of a door intrusion after a lateral trip of the vehicle PREFIRE ESP Activation of reversible belt tensioners in critical driving situations Detection and sensing Occupant protection Pedestrian protection 7

8 CAPS multiphase safety concept Risk phases 1 Risk avoidance: Traffic guidance Warn driver in advance in case of e.g. traffic jam or improper speed 2 Increased risk: Brake preparation Raise brake efficiency High risk: Driver warning / Accident mitigation Guide the drivers attention towards crash avoidance SOS Crash inevitable: Accident preparation Prepare occupant protection, slow down vehicle In-crash: Occupant protection Optimize occupant protection After crash: Information Inform rescue services, warn following traffic 8
