碩士 === 國立臺灣大學 === 機械工程學研究所 === 97 === This research aims to study the power management via dynamic programming for a parallel hybrid scooter. The system is composed of a fixed gear ratio made with a steel chain in place of the continuous variable transmission that is commonly used in scooters. As for the research structure of this thesis, this research established the dynamic system models first. Following that, it used the dynamic programming (DP) method to find the system’s operation points for the best fuel consumption under driving cycle ECE 40. Then, the operation points were used to modify the strategy for power management set in the controller. Then, this strategy will be put into a forward simulation to make a comparison with other strategies that are not based on the result of DP. This is to make sure that the effectiveness of the one from DP is superior to others. This research simultaneously designed a flywheel structure to emulate the inertia of the mass of drivers and scooter to provide an experimental platform for practice, without losing the effectiveness of emulation. Moreover, an authentication by mathematical and physical methods was also done. These can provide a use for the more in-depth research in future.
