  1. 9. Car-BorneInformation System 2005.6

  2. Agenda • Introduction to Automotive Electronics • Technology and Fields in Automotive Electronics • Project : ”Car-borne Information System” • Communication

  3. The development of Car Industry • 1885, Carl Benz invented the first car • 3 revolutions in car industry: • 1914, Ford invented streamline • 50s-60s, European car boost • 60s-70, Japanese car industry • In 2002, 57,700,000 new cars are sold.

  4. The development of Electronic • In 1946, The first computer ENIAC was born in America. • For the past half century • Army -> Scientific Research -> Civil • PC Revolution • Internet Economy

  5. Pervasive computing

  6. Pervasive computing • Whole new Devices • Tablet PC, PDA • Smart Card • Use Information Technology to change the old devices: • Digital Hospital, Industrial Control • Digital Appliance:DC,Set Top Box • Digital Automotive Industry: Automobile Electronics

  7. The birth of Automotive Electronics • Human’s new requirement to Car: • Mobility • Economy • Safety • Stability • Convenient • Traditional mechanical devices can NOT solve certain problems.

  8. The birth of Automotive Electronics Automobile Electronics = Automobile + Electronics

  9. Features in AE • Require Broad Knowledge • Mechanical Engineering, Automobile, Microelectronics, Automation, Computer hardware, computer software…… • Different level • Low Level: single chip, PLC • High Level: Embedded OS • No International Standard • Car-borne Bus:J1850,ODB-2,CAN,LIN,IDB

  10. Agenda • Introduction to Automotive Electronics • Technology and Fields in Automotive Electronics • Project : ”Car-borne Information System” • Communication

  11. Technology and Fields in Automotive Electronics • Hardware • Sensor • Bus • Chip, Storage, Display • Software Platform • Embedded Operating System • Application • Navigation, Positioning, Digital Meter.

  12. Hardware -- Sensor • Sensor:A -> D • Type of sensor: • Speed sensor, temperature sensor, light sensor, sound sensor.…… • No. of sensor in normal car: 30 – 100 • No. of sensor in advanced car:100 – 300

  13. Hardware -- Bus • Provide unified data transfer channel for all kinds of digital devices in car. • CAN(Controller Area Network) • Invented by BOSCH in Germany • 1M bit/s, high speed network

  14. Hardware –Chip, Storage and Display • Chip: • ARM7, Xscale and other embedded chips • Storage: • CD, DVD, CF Card,SD Card • Display: • Touch Screen,LCD, LED

  15. Software – Embedded Operating Systems OSEK
