Noeters per hour, has been a very mon thing. But the nature of fatigue and bad any other factors, may at any time cause various unexpected accidents. The accident on the high afraid there ilar to the ;domino; effect, the number of vehicles or even dozens of cars speed collision ented. To prevent car collided otive safety alarm device and a laser ranging system based on the smallest single-chip, appears safe folloergency alarm to alert the driver to sloeasures in order to achieve the purpose of effectively prevent rear-end collision accidents, improve active safety car.
