PURPOSE: A rear-end collision alarm system taking into consideration of driving behavior is provided to presuppose and alarm a circumstances that a rear-end collision is possibly occurred, taking into consideration of a situation in front and a driving behavior of a driver. CONSTITUTION: A rear-end collision alarm system taking into consideration of driving behavior comprises a distance detecting sensor member, a vehicle speed detecting sensor member, an alarming possible zone discriminating member(31), an alarming distance estimating member(32), a vehicle interval distance reduction determining member(33), and a alarming determining member(34). The alarming possible zone discriminating member(31) detects only a zone having a substantially useful information among information on a distance between vehicles from a distance detecting sensor. The alarming distance estimating member(32) estimates the first and the second alarming distances by using an absolute and a relative speeds of a front vehicle in an alarming possible zone by means of the vehicle speed detecting sensor. The vehicle interval distance reduction determining member(33) detects a variation of an interval distance between a vehicle itself and a front vehicle. The alarming determining member(34) drives a alarming output device when the vehicle itself is the first and the second alarming distances and a vehicle interval distance from the front vehicle is continuously reduced.
