Martin BÖHM I Thomas SCHEIDER | Oct. 17, 2007 Areas for improvement on Vehicle Positioning and Geo-referencing  I2V communication Lane banning Variable speed limit ISA with Infrastructure Link  V2I communication xFCD  Lane dependent information is necessary !

Martin BÖHM I Thomas SCHEIDER | Oct. 17, 2007 Lane Utilisation Information Change of Speed Change of Driving-Direction (change lane, take exit, use hard shoulder, no passing…)  Very specific recommendations/instructions  Reduction of information overload  No interpretation of the information by the driver necessary Enhancement of driving safety

Martin BÖHM I Thomas SCHEIDER | Oct. 17, 2007 xFCD  vehicle kinematics (wheel speeds,..)  safety systems (ABS, ASR, ESP event) activity, emergency flasher and alarm if a crash was detected  weather information (outside air temp, rain sensor status, fog lamp status)  vehicle GNSS position  Use vehicles as a floating probes to improve event detection

Martin BÖHM I Thomas SCHEIDER | Oct. 17, 2007 Lane specific localisation of the vehicle (for lane services)  positioning accuracy transversal accuracy +/- 1.0 meters longitudinal accuracy +/- 30 meters Requirements on Vehicle Positioning +/- 1.0 meters +/- 30 meters

Martin BÖHM I Thomas SCHEIDER | Oct. 17, 2007 Robust Positioning Unit „Robust Positioning Unit“ (RPU)  Requirements of the RPU: High accuracy, High reliability and Integrity.  Key technology „fault tolerant Navigation“ Galileo Receiver (GSSF) Wheel speed Turn-rate-sensor (Gyro) Differential-Odometry  Integration of available in car sensors (CAN-Bus).  Core of the RPU will be the sensor fusion.

Martin BÖHM I Thomas SCHEIDER | Oct. 17, 2007 Sensor Data Fusion Galileo GPS Gyro Optimum Navigation Sensor 2 Sensor 1 Optimum Sensorfusion Nav Algorithm Odometer  Important requirements for relevant applications in traffic systems:  Sensor fusion  High performance (Accuracy, Availability, Integrity)  Low Cost of On-Board-Units Bake Map Matching

Martin BÖHM I Thomas SCHEIDER | Oct. 17, 2007 RPU - Implementation  Migration of the developed optimal fusion algorithm towards a real time system.  Selection of an adequate hardware platform for the execution of the real time algorithm and other components (HMI, database, etc.).  Connection of the processing unit with the individual sensor components.  Design and implementation of interfaces towards other OBU elements.

Martin BÖHM I Thomas SCHEIDER | Oct. 17, 2007 Requirements on Map referencing Position-data must have a clear and unique reference to the in-vehicle map absolut accuracy  no problem relative accuracy  lane specific referencing? +/- 1.0 meters +/- 30 meters

Martin BÖHM I Thomas SCHEIDER | Oct. 17, 2007 Relative Accuracy in current maps Current geo-databases: Source: Link database (centerline of the road) Every link indicates numer of lanes  Calibration of map matching?
