Efficiency-based control strategy of dual-mode hybrid vehicle

Abstract

Now most of the instantaneous optimization for the power distribution of hybrid vehicle needs heavy calculation, which makes it difficult to be used on-line. Therefore, the instantaneous strategy which needs less computation is studied in this paper. The power split path is analyzed and the efficiency model is established based on a special dual-mode power-split hybrid vehicle. Using the efficiency model, a three-dimension lookup table is obtained through off-line genetic algorithm optimization. The three-dim…
