Route Based Optimal Control Strategy for Plug-in Hybrid Electric Vehicles
More restrictive emission legislations, rising fuel prices and the realisation that
oil is a limited resource have lead to the emergence of the hybrid electric vehicles.
To fully utilise the potential of the hybrid electric vehicles, energy management
strategies are needed. The main objective of the strategy is to ensure that the
limited electric energy is utilised in an efficient manner. This thesis develops and
evaluates an optimisation based energy management strategy for plug-in hybrid
electric vehicles. The optimisation methods used are based on a dynamic programming
and ECMS approach. The strategy is validated against Vsim, Volvo
Cars’ performance and fuel consumption analysis tool as well as against strategies
where parts of the optimisation is replaced by logic. The results show that
the developed strategy consumes less fuel both compared to the corresponding
Vsim strategy and the logic strategies.
