整合式適路性機車頭燈與後視鏡系統
Integrated Adaptive Front-light and Rear-view Mirror System for Motorcycles
摘要
本論文針對適路性機車頭燈與後視鏡系統進行整合與控制。現階段已有部分車廠研發出基本簡易功能適路性頭燈系統(Adaptive Front-light System,AFS)來改善固定式照明的缺點。另外加上適路性機車後視鏡系統，來改善因傳統機車後視鏡車輛行經彎道或其他狀況時產生視野死角，無法提供駕駛者後方視野的路況資訊，而導致交通意外事故的發生。因此本研究結合兩者優點，進一步發展出整合式適路性機車頭燈與後視鏡系統。 本研究在模擬部份利用機車動態分析軟體(BikeSim)探討機車動態，建立機車的數學模型。並針對機車頭燈與後視鏡進行不同路況模擬分析，如轉彎、上下坡、坑洞、減速墊的車身姿態變化，分析數據後設計其控制器，藉由LabVIEW程式的整合，控制LED陣列式頭燈與後視鏡，進行兩者整合式控制，並進行硬體規劃及驅動電路之系統整合，使整合式適路性頭燈與後視鏡系統可隨機車俯仰、側傾及車速之不同動態，以及行駛不同的道路環境，提供機車駕駛者更高的頭燈照射效率及照明範圍，減少不合適之眩光。以及更寬廣的後視鏡視野，亦能提升駕駛者安全，減少交通事故的發生。

The present study aims to integrate and control adaptive front-light and rear-view mirror system for motorcycles. Many automotive factories have developed Adaptive Front-light System (AFS) to improve disadvantages of fixed light. In addition, adaptive rear-view mirror system for motorcycles is utilized to improve the blind angle appearing when a rider passes along a curve with a traditional motorcycle, or when unexpected situation happens. The deficiency in providing riders with information on rear-view road conditions often leads to traffic accidents. The present study, therefore, integrates advantages of the two systems and goes a step further with the aim to developing an integrated adaptive front-light and rear-view mirror system for motorcycles. To investigate dynamic characteristics and establish a mathematical model for motorcycle, simulations in the present study were analyzed via motorcycle dynamic analysis software (BikeSim). Various road conditions (e.g., postural changes in making turns, going up- and down-slope, running over potholes and deceleration pads) are simulated for the AFS and rear-view mirror systems on motorcycle; subsequently a controller was designed. LabVIEW was employed to implement integrated control on the LED array front-light and rear-view mirror, hardware planning, and integration of driving circuits. In this way, the front-light and rear-view mirror system of the integrated adaptive motorcycle could act according to different dynamics of the motorcycle such as pitch angle, roll rate, velocity, and various road environments to provide better front-light illumination efficiency and coverage and to decrease inappropriate glare. As a result, a broader rear view was generated, safety of the driver was promoted, and occurrence of traffic accidents was decreased.
