Development and Simulation of a Hydraulic-Hybrid Powertrain for use in Commercial Heavy Vehicles

This research paper gives a description of the Permo-Drive Regenerative Energy Management System, (PDREMS), and describes the development of a quasi-static computer based simulation of the Hydraulic Regenerative system for use on heavy commercial vehicles. Modeling of the PDREMS was done in the Matlab/Simulink environment, which was then implemented into the NREL's Advanced Vehicle Simulator (ADVISOR). Validation of the model was achieved through comparison to fuel trials performed on a vehicle with the PDREMS fitted. From the ADVSIOR software, predictions of PDREMS performance were made under different operating conditions on a series of different driving cycles. A brief summary of the postgraduate research being done at Monash University is given in the conclusion.
