PREVENTION SYSTEM FOR CAR CRASH

摘要

PURPOSE: A car crash prevention system is provided to inform the risk of a collision by receiving the azimuth angles of surrounding cars to recognize the direction of the surrounding cars. CONSTITUTION: A car crash prevention system(100) comprises a compass unit(10), a crash prevention control unit(20), a crash risk sensing RF(Radio Frequency) communication unit(30), and an alarm unit(40). The compass unit senses the progressive direction of a vehicle. The crash prevention control unit sets the frequency according to the driving azimuth of the vehicle, controls an external frequency signal, and transmits the proximity conditions of surrounding vehicles. The rash risk sensing RF communication unit transmits an RF signal set by the crash prevention control unit and receives an external RF signal. The alarm unit outputs a warning sound according to the RF signal.
