針對目前汽車追尾事件頻發問題，提出一種防汽車車前和車后追尾的安全裝置設計。該設計以高性能、低功耗的8位AVR微處理器ATmega8L為核心，結合霍爾式車速傳感器、激光雷達測距裝置和MMA7260QT加速度傳感器，能夠兼顧車前和車后，摒棄以往設計中只考慮車前或車后單一性缺點，尤其適用于高速、夜晚或新手行車。
Abstract:
Aiming at the high frequency of vehicle rear-end collision，a safe device design of anti-vehicle rear-end collision is presented.In the design，the high-performance，low-power8-bit AVR microprocessor ATmega8L is utilized as a core combined with Hall-type speed sensor，laser-radar ranging devices and the acceleration sensor MMA7260QT.The design considers both the front and back of a car，and overcomes the drawbacks of former designs in which only the front or the back of the car is considered，so it is especially suitable for high-speed，night or the beginner’s driving.
