A comparative study of vehicle drive performance and energy efficiency

Conference Paper


Abstract


  • In this paper, two types of increasingly more efficient and greener vehicles

    are analyzed and compared. These vehicles are: a proposed conceptual seriesparallel

    powertrain, the University of Technology, Sydney plug-in hybrid electric

    vehicle (UTS PREY); and, a conventional series-parallel hybrid electric vehicle

    with an internal combustion engine .. The UTS PREY requires only a single electric

    machine to function as an electric motor or generator in different time intervals

    controlled by a special energy management strategy. The UTS PREV uses

    two energy storage devices, the battery and the ultracapacitor, which can work together

    effectively to maintain the state of charge at a high level in order to improve

    the vehicle drive performance and energy efficiency. With the assistance of

    a novel automatic transmission, the UTS PREY can operate under multiple modes

    to suit the needs of various driving cycles including those in an emergency. A special

    power and energy management strategy was developed to control the power

    flows within the vehicle according to the desired operating mode. The overall

    structure ofUTS PREY, known as UTS PREY code are derived and implemented

    numerically in the MATLAB/SIMULINK environment for further analysis.

    Through simulations, the performance of the UTS PREY has been evaluated in

    terms of the fuel economy, all electric range (AER), electrical consumption and

    operation cost for low and high density traffic patterns drive cycles. The comparison

    between the performance and efficiency of the UTS PREY and those obtained

    results using existing powertrains are also presented. The obtained results demonstrate

    that the UTS PREY outperforms most existing powertrains and has great

    potential in applications to passenger cars for city and urban transportations.
