The strong hybrid system is one of the best solutions to reduce the exhaust of carbon dioxide from vehicles. However it could be believed too big and too complicated for motorcycles. Yamaha develops the strong hybrid motorcycle "HV-X" with an unique power unit which consists of a 4-stroke 250 cm3 single cylinder engine and two 300 V AC motors with a planetary gear set in the simple one-room construction with the highly stiffened casing. They are controlled by the HV-X control system which contains a hybrid control unit (HCU), a motor control unit (MCU), a generator control unit (GCU), an engine control unit (ECU) and some battery management controllers (BMC) to attain 60% or less exhaust of carbon dioxide without a degradation of drive performances, but better acceleration. The strong hybrid system for the strong hybrid motorcycle "HV-X" embodies 5 different driving modes to accomplish better fuel economy and driving feeling. One is the mode of Pure-EV. Two is the mode of Parallel Hybrid. Three is the mode of Series Hybrid and/or Electric Continuous Transmission. Four is the mode of generating Five is the mode of re-generating. These combinations attain: (1) The strong hybrid motorcycle "HV-X" makes better acceleration comparing with same type of motorcycle which has one class bigger displacement. (2) The strong hybrid motorcycle "HV-X" attain 100% better fuel efficiency at the ECE40 mode, 40% at the WMTC mode and 55% at the WMTC mode comparing with same type of motorcycle which has same displacement. That is all about the summary and conclusion of the project. However, several subjects still remain, such as weight, cost, and so on. We would like to solve them, and certainly proceed further in the research and development.
