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.
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

    Introduction
   Car-borne information system is an electronic system
    that provides all kinds of information for car drivers and
    passengers.
   It consists of car-borne information terminal and
    information service out of the car
   They are integrated by mobile communication technique
    and wireless network.
   It not only includes information display and entertainment
    device in the car, but also serves as a bridge among car,
    mobile commerce and traffic information service
