= IT systems in cars =

There are multiple IT systems used in cars today. All cars manufactured today contain at least one computer. It is in charge of monitoring engine emissions and adjusting the engine to keep emissions as low as possible. The computer receives information from a many different sensors, including:
 * The oxygen sensor
 * The air pressure sensor
 * The air temperature sensor
 * The engine temperature sensor

Using the information from these sensors, the computer can control things like the fuel injectors, spark plugs and the idle speed to get the best performance possible from the engine while keeping emissions low. The computer can also sense when something has gone wrong and can inform the driver with the "Check Engine" light. A mechanic can read a diagnostic code from the computer and fix the problem.

**Vehicle** ** Tracking **
On a large scale, companies must track their vehicle fleets across the country or the world. GPS is the ideal tracking technology for tracking over large areas. To do this, every vehicle needs to be equipped with a GPS receiver. As the vehicle crosses the country, the GPS satellites track the truck's position. With GPS, the operator can request positioning at anytime.

Fleet tracking allows to track individual vehiciles in real time producing detailed statistics about there journey
