英文摘要： In face of high gas waste and pollution emission of buses and engineering vehicles, the basic theory and correlation technology research plan on the energy-safe hydrostatic hybrid vehicle system is examined. Theory of hydrokinetics and mechanical dynamics, Matlab/Simulink, and AMESim will be used in building the full vehicle simulation model to analyze the main factors affecting the efficiency of the system, further on optimizing the connection of main components and determining the rules of main components choice. New type of hydraulic energy regeneration system will be designed to research the corresponding of regenerate brake and friction brake, aimed at solving the problem of low brake energy regeneration efficiency and brake stability. A robust controller will be designed to restrain outside and inside disturb and enhance driving performance. A strategy of energy regeneration with engine and hydraulic components will be formulated, which will take full advantage of high power density of hydraulic system to distribute energy usage and reduce gas waste. Several working conditions will be simulated to test and perfect control strategy. This subject lasted three years, we have completed the expected target, and have cultivated 8 Ph.D students and 2 Master students. We also have published 24 related academic papers in academic journals and international conferences. The results of this item have important theoretical meaning for developing hydraulic hybrid system that possess independent intellectual property, saving energy and protecting environment.
