Abstract:
Recently, the hybridization of the conventional fuel vehicle has attracted
extensive attention among the automotive industry and related research
institutions to meet increasingly rigorous fuel consumption (FC) regulations and
emissions. This article introduces a hybridization design and parameter
optimization methodology to transform a conventional fuel powertrain into the
biaxial hybrid one. To utilize this hybrid powertrain, an energy management
strategy (EMS) is proposed based on the rule-based control strategy which
determines torque distribution between the engine and the motor according to the
engine optimal FC area. To achieve better fuel economy, an off-line optimization
of both control parameters and powertrain parameters is conducted using the
multi-objective particle swarm optimization (MOPSO) algorithm. The research on
the fuel economy potential of this hybrid powertrain, corresponding EMS, and
parameters optimization are carried out through simulation. The results show
that fuel economy improvement of 29.96% and 20.75% along the New European
Driving Cycle (NEDC) and Worldwide harmonized Light Vehicle Test Procedure
(WLTP) could be achieved.
