Abstract
This paper follows on from a previous publication [1] and describes the continued development of a generic Integrated Powertrain (IPT) model.
Simulation tools have been used for many years in engine and vehicle development programmes, to predict fuel consumption and emissions over various drive cycles. The concept phase of these programmes typically considers the overall layout and sizing of the components, with the detailed control strategies developed later. Today, the increased integration of vehicle sub-systems requires a high degree of overall control early in the programme, firstly, to allow the sub-systems to function, and secondly, to apply a similar quality of system control to each hardware iteration.
To address this issue, a control hierarchy has been applied comprising of a supervisor controller and multiple local controllers. The supervisor controller is developed early in the programme to allow the system integration to yield initial performance estimates, whilst the detailed local control strategies can be developed later.
The IPT model has also been extended to include generic sub-models of catalysts and particulate traps, allowing prediction of drive cycle emissions. These sub-models permit parameters such as substrate, size and position and, where applicable, regeneration strategy of the components to be evaluated.
