Transcript of "Fot Net Data Seminar Benmimoun, IKA"

  1. 1. FOT-Net Seminar Data acquisition at the German1-VMC in euroFOT Mohamed Benmimoun Institut für Kraftfahrzeuge (IKA) 13.05.2009, Munich www.eurofot-ip.eu
  2. 2. Introduction euroFOT • euroFOT project started in May 2008 • End of project in August 2011 9bm053.ppt - FOT-Net Seminar 2 Friday, 29 May 2009 www.eurofot-ip.eu
  3. 3. Introduction Vehicle management center • The vehicle fleet of an OEM is coordinated and managed by a Vehicle management center (VMC) • VMC is an entity which can be seen as the overall management entity. • Each VMC represents a country in Europe • Germany the VMC is divided into German1 German2 9bm053.ppt - FOT-Net Seminar 3 Friday, 29 May 2009 www.eurofot-ip.eu
  4. 4. Introduction VMCs across Europe Italian-VMC • CRF French-VMC Sweden • PSA (CEESAR) German1-VMC • FORD • MAN • VW/AUDI Germany German2-VMC • DAIMLER AG France • BMW Group Italy Swedish-VMC • VOLVO Technology • VOLVO Cars (VCC) 9bm053.ppt - FOT-Net Seminar 4 Friday, 29 May 2009 www.eurofot-ip.eu

  6. 6. Naturalistic FOT Definition of required data • Based on the hypotheses and the research question of the FOT so called performance indicators are indentified, e.g. TTC, THW, average speed etc. • Performance indicators can be derived from certain signals, e.g. vehicle speed, distance to forward vehicle, steering angle etc. • These signals have to be identified and are afterwards recorded by using of a data acquisition system • For the analysis the recorded data is uploaded to a database • GPS signal will be used to derive additional information from a digital map, e.g. road type, number of lanes etc. 9bm053.ppt - FOT-Net Seminar 6 Friday, 29 May 2009 www.eurofot-ip.eu
  7. 7. Naturalistic FOT Requirements As the FOT at the German1 shall be as naturalistic as possible The data consist only of CAN data No additional sensors (video, eye trackers etc.) will be used No additional tasks to the driver (change of hard discs, configuration of data logger etc.) will be required The FOT vehicles are driven by ordinary drivers Driver is also owner of the vehicle: Modification of vehicles has to be reduced to a minimum Data acquisition system (DAS) has to be installed in a manner, that: driver is not distracted by the DAS integration into the vehicle is conducted without significant modifications on the vehicle 9bm053.ppt - FOT-Net Seminar 7 Friday, 29 May 2009 www.eurofot-ip.eu
  8. 8. Naturalistic FOT Requirements • All 240 vehicles have to be equipped with a DAS, which enables recording of all relevant measured values • As driver shall not be stressed with additional FOT specific tasks Data upload procedure (upload of the data from the DAS to a certain data server) is performed without any requirements and actions with regard to the driver Data acquisition system with a GPRS modem (for wireless data upload, diagnostics and re-configuration) • Further requirements: The data needs to be stored at first on a temporary storage on the DAS Provision of GPS information of the vehicle location GPS receiver, hard disc (temporary storage) needs to be integrated into the data logger by ensuring a compact design, due to the modification restriction 9bm053.ppt - FOT-Net Seminar 8 Friday, 29 May 2009 www.eurofot-ip.eu
  9. 9. Data acquisition system Requirements • Logging of CAN data from the vehicle CAN-busses • Temporary storage of the logged data • Compression and encryption of the data • Integration of a GPRS modem • Wireless upload of the data via GPRS (autonomous or after request) • Communication interface to the data base (data upload, localisation, status information etc.) • Compact design for integration into the vehicles without significant modifications • Applicable for automotive application (high durability with regard to vibration, temperature etc.) • Reliability 9bm053.ppt - FOT-Net Seminar 9 Friday, 29 May 2009 www.eurofot-ip.eu
  10. 10. Data acquisition system Features of selected DAS Based on the requirements on the DAS a data logger with the following features was selected: • 4 CAN channels for logging from different CAN busses • GPRS quad band modem • GPS receiver • Built-in real time clock (with internal battery) • Socket for SD and SIM card • USB 2.0 • Application for logging configuration and data conversion • Support of DBC databases for signal selection • Firmware upgrade through GPRS 9bm053.ppt - FOT-Net Seminar 10 Friday, 29 May 2009 www.eurofot-ip.eu

  13. 13. Data upload and storage procedure Overview • Data upload and storage procedure for the German1 fleet will be defined and finally developed by IKA • Upload and storage procedure will be validated in the piloting phase • Data acquisition will be applied for a duration of 1 year • Estimated amount of data at the German1-VMC adds up to approximately 3500 GB (CAN only data and GPS information) • Recorded data will autonomously be uploaded via GPRS to a centralized data server • Entire process chain (from data recording to storage on the data base) is designed to work completely autonomously 9bm053.ppt - FOT-Net Seminar 13 Friday, 29 May 2009 www.eurofot-ip.eu
  14. 14. Data upload and storage procedure Overview 9bm053.ppt - FOT-Net Seminar 14 Friday, 29 May 2009 www.eurofot-ip.eu
  15. 15. Data upload procedure Communication interface • Based on a communication interface installed on the data base the data upload can be initiated • Communication interface provides all information with regard to the data logger and vehicle by using GPRS • The communication interface can be used for the following tasks: Autonomously synchronisation of data View DAS which have connected to the server and its most important parameters Map matching of vehicle‘s position, based on the GPS information View the received CAN frames and received GPS frames from each monitored DAS Remote control of DAS Re-configuration of DAS 9bm053.ppt - FOT-Net Seminar 15 Friday, 29 May 2009 www.eurofot-ip.eu

  17. 17. Data management Central management system • The communication interface of the DAS will be integrated into the central management system (CMS) • CMS manages the whole data upload and enrichment procedure Fleet of 250 vehicles ... equipped with CTAG DAS GPRS Service Provider Operators Central Management System (CMS) 9bm053.ppt - FOT-Net Seminar 17 Friday, 29 May 2009 www.eurofot-ip.eu

  19. 19. Next steps • First tests for the assessment the DAS have been conducted • Extensive tests of DAS will be conducted within the next weeks • The software for the upload procedure is available but needs to be integrated into the CMS • CMS will be developed as soon as final requirements on data upload and storage are defined • The validation of the software and hardware will be conducted within the piloting phase in September 2009 9bm053.ppt - FOT-Net Seminar 19 Friday, 29 May 2009 www.eurofot-ip.eu
