含儲能飛輪之混合動力車輛燃油消耗量之分析

本研究建立含儲能飛輪之混合動力車輛之概念。本車輛模型含內燃機引擎、無刷同步電動機、無段式變速器、發電機、脈波頻寬變調電源控制器、行星齒輪系統與儲能飛輪。儲能飛輪將驅動發電機，產生電能以供電動機使用，可降低混合動力車輛之燃油消耗量。推導引擎與電動機輸出之功率與扭矩，以及引擎之制動燃油消耗比，無段變速器與行星齒輪之減速比。由控制器以模糊理論控制引擎與電動機之動力分配率。選定系統參數之值，以日本10-15模式模擬行車速度，計算儲能飛輪對車輛燃油消耗量之影響。以一個只有引擎之單一動力源動力系統之車輛模型作為比較之用，採用日本10-15行駛模式循環，其燃油消耗量為16.58 km/l。假設儲能飛輪之初始轉速為0 rpm，飛輪最終減速比為0.231，極慣性矩分別為0.6 kgm2 、1.2 kgm2、1.8 kgm2與2.4 kgm2時，第4次日本10-15模式循環時，已達到穩定狀態之燃油消耗量分別為22.65 km/l、23.86 km/l、23.99 km/l與25.01 km/l。比較兩個系統，含儲能飛輪之混合動力系統的燃油消耗量分別降低了36.62%、43.92%、44.71%與46.76%。

This study generates a conceptual hybrid power vehicle with an energy storage flywheel. The flywheel that drives a generator to generating electric power for a motor, improves the fuel economy of the hybrid vehicle. This hybrid power vehicle consists of an internal combustion engine, a brushless synchronizing motor, a continuously variable transmission, a generator, a pulse width modulation electric controller, a planetary gear system, and an energy storage flywheel. The energy storage flywheel drives the generator and the motorthat improves the fuel consumption of the vehicle. The power and torque of the engine and the motor, the brake specific fuel consumption of the engine, the reduction speed ratios of the continuously variable transmission and the planetary gear system are derived. The controller with the fuzzy theory is used to determine the power distribution of the engine and the motor. With the specific values for the parameters of the system and using the Japanese 10-15 driving mode, the fuel consumption of the vehicle is analyzed. The fuel consumption of the vehicle with a single power of the engine by using Japanese 10-15 mode is 16.58 km/l, that is used for comparison. With the assumed initial angular velocity of the flywheel to be 0 rpm, the final reduction speed ratio to be 0.231 and the moment of inertia to be 0.6 kgm2, 1.2 kgm2, 1.8 kgm2 and 2.4 kgm2, for the hybrid system, the fuel consumptions at the 4th block of Japanese 10-15 mode are 22.65 km/l, 23.86 km/l, 23.99 km/l and 25.01 km/l. The fuel consumptions are improved 36.62%, 43.92%, 44.71% and 46.76%.
