Definitions

  • the present invention relates to a vehicle safety system that enables informing the problems, which occur in traction and handling, and cause loss of steering control of motor vehicles, to the other vehicles in the traffic.
  • Active safety systems refer to systems which aim to change the response of a vehicle so as to improve safety of the vehicle before crash or during the crash, and to prevent a crash by using the information gathered from the vehicle's external environment.
  • the components used for active safety enhance driving safety and prevent crashes.
  • Direction indicators, brake lamps, lamps that measure the vehicle acceleration and warn the traffic at the back of the vehicle in case of emergency braking Anti-Slip Regulation (ASR), Hill Holder (system which prevents backward rolling of a vehicle on a hill), All Wheels Drive (AWD), Electronic stability program (ESP), lateral driving support systems are among active safety system applications.
  • Passive safety systems refer to internal systems which do not change the response of the vehicle according to the crash scenario or crash magnitude, and which function passively to prevent injuries.
  • Safety belts and air bags are among applications of passive safety system.
