碩士 === 元智大學 === 機械工程研究所 === 88 === A series hybrid electronic scooter for elder and maimed people has been developed with aim of not only fuel economy and less charging time but safety. The central processing system for the scooter including velocity and acceleration control, energy management strategy, and engine throttle control of generator was also presented in this paper. Velocity and acceleration control has developed mainly for elder and maimed people. When user speeded up, the control system limited maximum velocity and maximum acceleration to keep user safe and comfortable. Energy management strategy was based on splitting power demand between the battery and the generator such that the power sources were operated at high efficiency, and the generator was only started outside. The generator output voltage could return to command voltage with load variation by engine throttle control of generator. The development of hybrid scooter for elder and maimed people made scooter more popular and improved their quantity of life by traveling and playing more.
