摘要

本文以一機械式加減速與離心力感測裝置應用於車輛輔助照明之感測模擬與測試。該裝置以一特定形狀軌道配置有可滾動並具導電作用之球體，由機械式加減速與離心力感測裝置控制輔助照明設備明滅。
於一懸臂樑上搭載機械式自動感測裝置，利用伺服馬達進行旋轉加減速運動，分別模擬車輛車速與車身傾斜角度，偵測汽車轉向狀況或路面上坡下坡狀況，主要內容為加減速與離心力機台設計、離心力與傾斜度感測裝置分析、檢測與控制電路設計與嵌入式控制系統設計與測試等四個部分。藉由加減速與離心力參數與機械式感測裝置，可有效地達成車輛自動輔助照明的功能。
最後文中將與電子水平儀、主動式轉向頭燈等系統進行其車輛速度、補光控制方法與價格性等各項分析，其機械式加減速與離心力感測裝置價格較為低廉，利用機械式原理可找出電子水平儀無法感測之加減速狀況，更可應用於各項機台之自動檢測裝置。

This article uses a mechanical steering angle and tilt angle sensing device to simulation for automotive auxiliary lighting. The device has a conductive metal ball which rolling in particular shape track. This article uses this device to control auxiliary lighting equipment turned on or turned off.
Mechanical sensing device is placed on the cantilever, by used servo motor rotation deceleration movement. This article simulates vehicle traffic speed and the vehicle body tilt angle. Detect vehicle steering status or condition of road surface slope downhill. The main content is acceleration, deceleration and centrifugal force machine design. Centrifugal force and tilt level sensing device. Detection and control circuit design. Embedded control system design and testing of four parts. By acceleration and deceleration, and centrifugal force parameters and mechanical sensing device can be effectively reached the vehicle the automatic auxiliary lighting function.
This article completed the steering angle and the tilt angle sensing device used in automotive auxiliary lighting. This sensing device is cheaper than electronic level sensor and gyroscope. The electronic level can’t sense plus and deceleration situation. This device can use the principle of mechanical to find plus and deceleration situation. It also can use in automated detection machine.
