Abstract

This paper presents a method to compute an approximation of actual internal combustion efficiency which is real time capable. Further, the implementation of this efficiency prediction into a hybrid electric vehicle energy management strategy is shown. It enables the computation of the optimal torque split under any varying condition. This real time capable approach, validated on the engine test bench, allows efficient operation of hybrid electric vehicles under real driving conditions. Research results show that, especially under conditions relevant for engine-knock, the potential fuel reduction is up to 10 % compared to actual known operating strategies exists.
