This paper presents the possible improvements in regenerative braking potential and fuel economy due to application specific design. A regenerative braking Matlab/Simulink environment is developed for series, parallel and power-split drivetrain configurations. Fuel economy and efficiency are evaluated and compared for given drive cycles in a flexible simulation architecture containing reduced-order component models. Verification against a test vehicle showed good agreement in modelling energy savings due to the capturing of 78.92 Wh/km, resulting in a 15.52% fuel energy savings ratio at a 53.40 mpg rating. Key findings from parametric studies were fuel savings due to drive-style suitable powertrain configuration (Δ119.0 Wh/km, Δ16.32 mpg) and sensitivity to vehicle design parameter changes depending on driving scenario.
