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.

In order to improve the lifetime and performance of a hybrid electric vehicle, one of the most challenging tasks is to improve the performance of the electrical energy storage, regarding the electrical power and energy capacity. By introducing a supercapacitor as auxiliary source to increase the system power and to take over the battery stresses, the performance of the combined energy storage unit is improved. This paper introduces a completed model of energy storage system, including a pack of batteries, a pack of supercapacitors and a control strategy. The aim is to discharge the capacitors when the required power from energy storage is above a threshold meaning that the driver needs a boost of power for a period of time. Because of their high density of power supercapacitors have more efficiency in delivering it for short time. This has a positive impact on the fuel consumption and the state of charge at the end of the drive cycle.
