Slide1: Intelligent Integrated Safety: The Concept Dr. Ulrich Eichhorn Tycho von Jan 10.6.2002 Vision: Safest Transport System through Integrated Safety: Fatalities per Billion km in different Means of Transportation Vision: Safest Transport System through Integrated Safety What is Integrated Safety?: What is Integrated Safety? Integrated Vehicle Safety: Driver Infrastructure Passive Safety Active Safety Vehicle Safety: Preventive Safety Integrated Vehicle Safety Definition of Passive, Active and Preventive Safety: Definition of Passive, Active and Preventive Safety Why Intelligent Integrated Safety?: Why Intelligent Integrated Safety? In the past, vehicle safety systems were designed according to the availability of technologies. For the infrastructure, there is a cost benefit relation guiding the design of new streets, crossings etc.. The driver is educated when getting his driver‘s licence. Usually he or she does not receive formal training thereafter. Though leading to a significant reduction of fatalities in the past, this divided approach seems not to be the optimal approach in the „electronic age“. Why Intelligent Integrated Safety (cont.)? : Why Intelligent Integrated Safety (cont.)? For preventive safety, it is necessary to make use of the capabilities of the vehicle, the infrastructure and the driver. Considering the safety needs of society, it is important to consider the most frequent causes of accidents and to develop safety functions and countermeasures in order to achieve maximum reduction in casualties. Integrated Project: „Integrated Safety“: Integrated Project: „Integrated Safety“ This approach of looking at the most frequent accidents and clustering them into accident situations is taken by the EUCAR Integrated Project Proposal „Integrated Safety“: 1 Integrated Road Safety Workshop - Renault Technocentre - 28 - 29 May 2002 Vision & Perception Vision & Perception Guidance & Control Protection (incl . Compatibility & vulnerable road users) Protection (incl . Compatibility & vulnerable road users) Guidance & Control IP Integrated Safety Coordination (Steering committee) Accidentology & Safety functions Guidance & Control Assessment & Deployment conditions Protection (incl . Compatibility & vulnerable road users) Vision & Perception H/M Interface Architecture Sensors / Actuators H/M Interface Architecture Sensors / Actuators H/M Interface Architecture Sensors / Actuators Accident Clusters: Accident Clusters Reconstruction of a Real Accident „loss of control“: Reconstruction of a Real Accident „loss of control“ Definition of Safety Functions: Definition of Safety Functions Safety functions can best be explained by the previous example: „Loss of control“: 1.) Prevent vehicle from leaving the road 2.) Assist driver in steering back on the road 3.) Mitigate impact 4.) .... In an integrated approach it has to be determined how each safety function can best be realized and what are the effectiveness, costs and deployment scenarios. Mitigate Impact through Passive Safety: Passive Safety generated most of the safety benefits in the past. Physics and human physiology limit further progress. Mitigate Impact through Passive Safety Infrastructure Solution: Rumble Strips: Infrastructure Solution: Rumble Strips In the United States of America very cost effective rumble strips can be realised: Cost 200 $/km In Germany these rumble strips are not legal. Elements glued to the road cost about € 4200/ km LACOS - LAteral COntrol System: LACOS - LAteral COntrol System Lane Departure Warning Assist driver in steering back on the road: oversteering understeering during load cycle in a curve during accelerating in a curve conventional with ESP conventional with ESP yaw yaw brake power brake power yaw yaw Assist driver in steering back on the road ESP - Electronic Stability Program Reconstruction of the accident with ESP : Reconstruction of the accident with ESP Deployment scenarios, legal aspects: Deployment scenarios, legal aspects None of the technologies will help, if: The deployment scenarios are not considered. The legal aspects, i.e. regulations and product liability are not solved. In these areas it is essential that all players work closely together. Therefore we welcome the opportunity to work together in the E-safety Action Plan, the Road Transport Research Advisory Committee and the Integrated Projects in FP6. Conclusion: Conclusion Passive Safety is in today´s focus of attention and has created most of the safety benefits in the past. Active Safety is already contributing a significant part to vehicle safety with systems like ABS, ESP. Preventive Safety is a major topic for research. Integrated Safety, including vehicle, driver, and infrastructure, is necessary to achieve our vision of becoming the safest transportation system. To create integrated safety a common approach of vehicle manufactures, suppliers, and public authorities is needed to remove technical and legal roadblocks for integrated safety.
