Intelligent Energy Management in a Vehicle with Integrated Starter Alternator

Abstract

In this paper an intelligent control strategy to extract the full benefits from a passenger mild hybrid vehicle is developed and described with simulation results. The mild hybrid vehicle is equipped with an integrated starter alternator (ISA), which is placed directly on the crankshaft in the general location of the present flywheel. Continuously variable transmission (CVT) is used to control the internal combustion engine (ICE) operating point. By intelligent fuzzy logic control (FLC) and CVT control, optimal torque requests to ICE and ISA are made as well as forcing the ICE to operate in desired speed.
