Fuzzy logic controller in an Electric Vehicle with dynamically changing centre of gravity

Pure Electric vehicle has become the better option in comparison with the other alternative fuel based vehicles overcoming all constrains regarding distance coverage, vehicle speed and size. A vehicle performance and energy enhancement system in an Electric Vehicle is very much dependent to load characteristics. The distribution of load, placement of parts and components on a vehicle will not remain the same and diametrically change, changing the centre of gravity. In this paper an advanced electric vehicle is considered. It is important to consider shifting of centre of gravity (COG) position, as it shifts dynamically depending on change of load distribution, running and road condition and requires optimum Fuzzy logic analysis for best controllability and performance of motors. The change of COG is not only affects the motor control strategy but also affects the Electronic Stability Control (ECS) of vehicle. This paper addresses affect of dynamically change of COG on real time processing of vehicle´s performance and its effects on ESC System.
