Abstract:

Aiming at the characteristics of multi-objective,with constraints
and highly non-linear in the parameter optimization of a
 PSHEV using the
genetic algorithm toolbox and ADVISOR without the GUI,a simulation model of the
parameter optimization of PSHEV was built,which can be used to simulate both the powertrain parameters and the control strategy parameters.
The constraints of the model were  the designed dynamic performances and the objective
function was the fuel consumption and emission performance.Finally,the simulation
model was applied to simulate a PSHEV.Simulation results demonstrate that the
 fuel consumption of PSHEV is reduced significantly and the fuel economy as
well as emission performance of a PSHEV are also improved under the premise of
guarantee of the dynamic performance.
