What Is Car Computer?

The car computer is a highly integrated vehicle multimedia entertainment information center with high temperature resistance, dust resistance and shock resistance developed specifically for the special operating environment of the car and the characteristics of electrical circuits. At present, only the top models are equipped with similar intelligent vehicle systems.

The car computer can mainly achieve functions including in-vehicle multi-media entertainment (Internet access, games, phones, etc.), GPS satellite navigation, professional diagnosis of car information and faults, mobile office and industry applications, etc.

However, the car computer is not so out of reach. Depending on how expensive the car is, there can be all sorts of other computers. For example:

  • A computer controlling the automatic transmission.
  • A computer reading the wheel speed and controlling the brakes, if the car has anti-lock brakes.
  • A computer controlling air bag.
  • A computer used for radio or CD player with a digital display.
  • A computer used for cruise control systems.
