利用高壓看門狗定時器加強汽車安全系統

Abstract: As electronic systems take over many of the mechanical functions in a car—ranging from engine timing to steering andbraking—there is a growing concern about fault tolerance. There should not be a single point of failure that would prevent a car fromat least "limping" off the road or making it to the nearest service station. Redundant systems, watchdog timers, and other controlcircuits are used to reroute signals and perform other functions that ensure that a vehicle can safely make it off the road when afailure occurs.

基于ARM單片機的自動測高測距小車

生活中許多目標的高度和水平距離需要進行測量。目前主要的測量方法，仍以傳統的皮尺丈量為主，測量效率不高，有時還很不方便，沒有技術成熟的數字式測高測距產品。以基本的數學方法為理論依據，利用遙控小車做為載體，采用角度傳感器測量角度、霍爾傳感器測量水平距離等，通過單片機LM3S615進行數據計算，實現了對待測目標物體的高度、水平距離等數據的快速、精確和數字式的測量，高度測量精度可達99.06%，水平測量精度則可達98.06%。 Abstract: In our lives， the height and horizontal distance of some goals are needed to be measured. Because the currently used methods are still traditional tape-based measuring methods， and the measuring efficiency is low and inconvenient so some kinds of digital and portable measuring methods or instruments are needed. Based on the basic math theory， this paper designed and manufactured a portable， digital and remote controlled measuring mobile small vehicle， which assembled with angle measuring sensor for angle measurement and Hall sensor for horizontal distance measuring. MCU LM3S615 calculated the height and horizontal distance data gotten from these sensors. The measuring process is simple， the measuring results are more accurate and the measuring efficiency is higher than traditional measure instruments. The accuracy of height and distance measurement can reach 99.06% and 98.06%.

基于AVR的新型防汽車追尾安全裝置設計

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.
