Evaluating the Implementation of a Fuzzy Logic System for Hybrid Vehicles as Alternative to Combustion Engine Buses in Big Cities

Part 3: Knowledge Based Production ManagementInternational audienceThe public transportation in urban centers involve many challenges related to environment. One of these challenges is reduce air and noise pollution in big cities. In São Paulo, for instance, it is estimated that 98 % of the transport are made using buses with combustion engine, which are responsible for greatest part of air and noise pollution. Therefore, it is necessary to develop studies that help change the public transport policies in major cities, favoring the use of electric and hybrid buses. Thus, this paper aims to simulate the use of hybrid bus with fuzzy logic applied to improve the efficiency of this type of system. We made six simulations with MATLAB© software and Fuzzy Logic Toolbox, considering velocity, topography and battery status as input variables. The results showed an effective control of the fuzzy system, with the feasibility of combining this with others experts systems
