本研究主要探討車輛節能方法之應用，於車輛後車廂上裝置垂直軸式風力發電機，利用車輛行駛之風阻，轉換為電能，供應車輛電系，不僅能增加發電量，也能達到節能省油的效果，最後探討其節能效益及評估車輛結合風力發電機之可行性。
研究先以CAD軟體建立車輛3D模型，之後用CAE軟體進行車輛行駛風力模擬可得知車輛整體之風阻情形，並設計出可提升車輛穩定性且可節能之風力發電機應用於車輛之上。
實驗將一具微小型垂直軸式風力發電機設置於車輛後車廂位置，使用單顆電池獨立充電，將此電瓶當作備用電源。發電量測試方法以固定葉片面積方式，使用PVC塑膠板、鋁板、鍍鋅鋼板等三種，實車行駛於快速道路上，得到實驗結果為鍍鋅鋼板具有最好的發電效益。
實驗結果顯示，在CAE模擬之中，當車體外界風速為15m/s時車輛整體阻力係數從0.573上升到0.5738，但升力係數也從0.528下降到0.3988，結果可知，加裝此垂直軸風力發電機組可增加車輛高速行駛穩定性。

This study mainly discusses an application of vehicle energy-saving methods. A vertical-axis wind turbine was installed on the rear compartment of the vehicle. It utilized to the wind resistance of driving vehicle to convert wind power into electric energy and supply to the vehicle electrical system, which not only increased the electricity, but also achieved energy saving and lower fuel consumption. The effect of energy efficiency is finally explored and the feasibility of combining wind turbines with vehicles was also evaluated.
The research establishes the vehicle 3D model with CAD software fiest, and then the CAE softwared was utilized to implement the vehicle wind simulation to know the overall wind resistance of the vehicle, and arehicle wind charging system turbine that can improve the stability of the vehicle and save energy was developed.
The experiment placed a micro vertical axis wind turbine in the rear compartment of the vehicle, using a battery as a backup power source to charge independently. The power generation test uses three different plates which are plastic, aluminum, and steel. The vehicle is driven on high way, and the experimental results showed that the steel plate has the best power generation.
The experimental results show that in the CAE simulation, when the external wind speed of the vehicle is 15m/s, the overall drag coefficient of the vehicle increased from 0.573 to 0.5738, but the lift coefficient also decreased from 0.528 to 0.3988. As a result, it is visible that the stability of the vehicle was improved when driring at a high speed as wind turbine was installed.
