  2. About Us Department of Telecommunications Prof. Dr.-Ing. Horst Wieker Department of Automotive Engineering Prof. Dr.-Ing. Wolfram Seibert Aggregation of competence on vehicle engineering & telecommunication systems

  3. Vehicle-to-Vehicle Communication Projects Source: Prof.Dr.-Ing.habil. Raymond Freymann (BMW) – Connectivity and Safety

  4. 16.0 3.9 6.2 11.1 2.2 22.8 26.1 Motivation: Accident Statistics Road accidents in 2003 Cause of accidents resulting in injuries 1) 86.1 Other Caused by pedestrians 1 86.1 5.6 Under influence of alcohol 5.1 Potential for improvement through vehicle communication! Driving in wrong lane, overtaking, passing Right of way, traffic regulations, turning corners, pulling in and out,u-turns Driver 2) Vehicle 2) 3) Other Pedestrians Driving too fast, tailgating Road conditions • Source: Verkehr in Zahlen 2003, Deutscher Verkehrs-Verlag • Cause of accident determined by the police • Automobiles incl. motorcycles, mopeds, motor bicycles and other vehicles • Technological faults, maintenance faults

  5. Vehicle – Vehicle – Communication Fahrzeug – Infrastruktur – Kommunikation Areas of Application for Vehicle-to-Vehicle Communication On the highway In city traffic Danger alert Intersection assistance Warning beacon Traffic flow Communication with traffic signals

  6. Foresighted Driving In future, telematics (maps, communication and networking) will play an increasingly important role in safe and efficient driving.

  7. PReVENT WILLWARN – Local Danger Alert Slippery road surface Obstacle behind a bend Danger alert • Obstacle alert • Warning in situations with poor visibility or reduced road grip • Warning at road works … through vehicle communication Reduced visibility Road works

  8. Vehicle-to-Vehicle Communication Requirements • Available everywhere • Existing technology • No operating costs Solution • Wireless LAN • Available on every computer today • Information distribution via Ad Hoc networks

  9. A a e b c 1 b 2 B e 4 3 d d c e PReVENT WILLWARN – Local Danger Alert • In rural areas: • Store & forward • On highways: • Ad Hoc networking Routing protocols coordinated with the project NOW – Network on Wheels

  10. Ad Hoc Communication • Random group of vehicles creates an(Ad Hoc) communication network • Some vehicles leave the network, others join it • Communication between vehicles in new configuration • Advantage of Ad Hoc: no operating costs

  11. Danger Identification The vehicle as sensor • Vehicles already feature a large number of reliable electronic driving safety systems today (ABS, ESP, …) • All systems function more or less independently as stand-alone applications • Goal: information from these systems should be usedin a coordinated fashion to help identify dangers

  12. GPS(Navigation device not required) WLAN Light, wipers,rain sensor, … Data from ESP/ ABS/ ASR Additional sensor information e.g. lateral/longitudinal acceleration, steering angle/steering speed, crash sensors Data fusion and logical combination Slippery surfaces 3-5 steps Poor visibility Obstacles Danger Identification • Goal: affordable solution for everybody  in particular also small cars • Retrofitting possible • with appropriate danger detection system adapted to the vehicle • without danger detection system, to relay information • Exclusive use of off-the-shelf sensors

  13. Future communication architectures & related challenges • Applications (Traffic-, Fleet Management, etc.) will function via seamless access to various communication technologies (CALM +) • Interfaces, handover procedures, delay etc. • Local communication (Ad Hoc) has to be harmonised to infrastructure communication • Way from WILLWARN scenarioto CVIS scenario

  14. Future communication architectures & related challenges • Integration of personal mobile devices (PDAs) has to be ensured • Evolution from vehicle-to-vehicle communicationto road user to road user communication (R2R-Com) • Systems will be very complex • Have to be adequately explained to the driver • Must be easy to handle so that the driver can concentrate on his main task, which is…Driving the vehicle!
