In order to reduce fuel consumption and emissions in plug-in hybrid electric vehicles (PHEVs), it is equally important to select an appropriate drive train topology and to develop a suitable power flow control strategy. There are many control strategies that have been developed and presented. Most of them are expansions of hybrid electric vehicle control strategies and do not maximize the true potential...
The control problem for a hybrid vehicle powertrain is commonly tackled as an optimal control problem, although this is often used in a general sense as opposed to a strict mathematical definition. The problem may be characterised in many ways depending on the performance objective, the hybrid vehicle model considered, the constraints imposed and the available control actions. However, as a general...
A new method based on DIRECT algorithm was presented for parametric optimization of control strategy for hybrid electric vehicles. A logic threshold control strategy (LTCS) implemented in an existing hybrid vehicle was considered. A set of parameters was adopted in the LTCS to command the operation of the vehicle. The optimal adjustment of these parameters was formulated as a constrained nonlinear...
