Backward Modeling and Energy Management Optimization of a Two-Clutches Series-Parallel HEV for Efficiency Assessment
2012
Abstract Hybrid vehicles are complex systems using more than one energy source. Different topologies have been developed and can satisfy the dynamic specifications with more or less energy efficiency. The fuel economy potential comparison between different topologies is not an obvious task because of the diversity of the hybrid solutions and the strong influence of the control strategy on the vehicle efficiency. This paper describes the use of a backward looking approach associated to a global optimization algorithm for the efficiency assessment of a series-parallel hybrid vehicle with 2 clutches. This approach provides fair conditions for comparison as the influence of the vehicle control is disabled. Energy management results as well as global consumption on different cycles have been given and discussed.
