碩士 === 國立臺北科技大學 === 車輛工程系所 === 93 === This paper proposes a novel technology of an electric transmission system for electric three-wheel vehicles. By changing phase windings of the motor, the electric transmission system can compose five gear types for different driving condition. Fuzzy control is applied to design a torque control. With the proposed electric transmission system, the performance of the power system is improved. This paper also presents an electric brake system with hydraulic brake. During the braking phase, the motor turns into a generator which can transform the vehicle’s kinetic energy to useful electric energy. The PWM controller is applied to control the brake torque for different braking case.
