A distributed control strategy for a hybrid electric vehicle

This paper describes a distributed control strategy for a hybrid electric vehicle, in order to reduce the fuel consumption, and to maintain a reasonable state of charge (SOC), at the end of the drive cycle. The vehicle is like a system built from control nodes, every one of them having the same priority. The control laws are based on the dc-bus signaling, such way that every source of power (control node) is entering or leaving the network (dc-bus) depending on the voltage thresholds. The algorithm was tested using Matlab Simulink and ADVISOR interface. The results include statistical comparisons of the standard drive cycles using default model and the modified control strategy.
