One 'mind experiment' would be to rig up an rpm-to-assist control system that would add electric boost in proportion to the inefficiency, power range of the ICE. The idea is if the engine is in a fuel inefficient region, add electric boost to offload the engine. But as the engine reaches fuel efficient ranges, the electric power backs-off.
Just a random thought,
Bob Wilson
