Implementation of Dedicated Short Range Communications Combined with Radar Detection for Forward Collision Warning System Academic Article uri icon


  • The Forward Collision Warning System (FCWS) has become an important research topic in recent years. Many FCWS products are used in the real world. However, these FCWS products cannot provide emergency braking events warning from the vehicle in front. Hence, this paper proposes a Dedicated Short Range Communications (DSRC) system combined with radar detection for an FCWS mechanism. The mechanism proposed by this paper will actively probe the emergency brakes of the vehicle in front and broadcast warning information with the Global Positioning System (GPS) position. Moreover, this mechanism uses warning information based on the GPS position to calculate the time of collision in order to alert the driver.
