Electric two-wheels without transmission encounter unreasonable currents necessarily provided by battery and severely low energy-efficiency when running up a slope. To be sure, both of the life of batteries and driving range of the vehicle are short, and fortunately this thesis develops a solution thereto. Such a solution includes a specially designed Automatic Manual Transmission to regulate motor currents. Therein, a single-directional bearing working embedded controller replaces a conventional clutch for energy saving. In this work, embedded-controller design is presented and experimental data verifies such a design.
