Forward Collision Warning (FCW) system testing

FCWS VBOX TestingForward Collision Warning systems (FCWS) have been proven to actively avoid or drastically reduce the severity of accidents. They work by monitoring the road, providing the driver with sufficient warning to change direction or apply the brakes when entering a predefined threshold to the vehicle in front.
Validating the performance of these systems is therefore vital, with the National Highway Traffic Safety Administration (NHTSA) stating that systems must activate before the time to collision reaches a minimum of 2.1 seconds.

The Base Station system comprises of:

  • VBOX3i-RTK 100Hz GPS data logger in both the subject and target vehicles
  • Brake pedal sensor
  • DGPS RTK Base Station
  • Linking radio pair
  • Video VBOX (optional)

  • VBOX3iSL-RTK 100Hz GPS data logger in both the subject and target vehicles
  • Brake pedal sensor
  • Linking radio pair
  • Video VBOX (optional)

To help achieve the speed, distance and braking force required when testing, Racelogic has teamed up with AB Dynamics to develop a Controlled Braking and Acceleration Robot (CBAR). This regulates the brakes and accelerators on both cars, shortening the length of track required.
Live separationvalues can be viewed on a laptop or tablet PC whilst testing, allowing users to instantly compare their data with NHTSA regulations to show a simple pass/fail indicator.
