電動載具為降低系統重量和製造成本，系統多採用馬達配減速齒輪箱架構，如要求更寬廣的操作範圍，則受限固定齒比減速的設置，需提升電機功率規格，因此本研究係透過磁性齒輪電機雙輸入單輸出的特性，再搭配電動馬達來實現不同減速比的調變功能，使其能根據使用場合情境調整不同的控制策略。於低速行駛階段設計扭矩模式，克服載具於起步時所需克服之靜摩擦力，並透過策略實現動力分配之功能；於中低速行駛階段後，則透過磁性齒輪電機調變減速比，提供主動式無段變速，使電動載具加速較為平緩，再導入負載調變減速比函數，根據不同負載調變減速比之功能。為解決現行機械式差速器之差速鎖定及防打滑性能問題，本研究基於雙組磁性齒輪電機動力調控模組設計電子電控式差速系統(EDS)，相較於機械式差速器，可主動式給予差速命令，不再受機構所限制，並藉由同動控制策略，於輪胎打滑時，及時給予轉速補償，避免載具輪胎打滑。最後建立實驗平台，以驗證本文所提之動力調控策略的可行性。

This thesis proposed a new power regulation strategy for electric vehicle, which adopted the 2-input/1-output characteristics of a magnetic-gear motor combined with an electric motor to realize the modulation of different reduction ratios. The torque mode was designed as the low-speed driving phase to overcome the static friction that a vehicle required when starting. The sport mode was plotted as the medium speed driving phase to provide active stepless speed changes and adjust the reduction ratio according to different loads. In order to solve the problems of differential locking and slippage of the current mechanical differential, this research was based on the dual magnetic-gear motor power regulation module to design the electronically controlled differential system (EDS). The differential command was actively given and is no longer restricted by the mechanism. With the synchronized motion control strategy, the speed compensation was provided in time when the tires slipped. Finally, an experimental platform is established to verify the feasibility of the proposed power regulation strategy.
