Abstract
This article elaborated the original drivetrain system design for IVECO hybrid
electric city mercial vehicle of Nanjing Automobile Group Corporation.
Through the match design, mathematic modeling, simulation and test analysis, problems
have been found and fixed.
Firstly, the Integrated Startor Generator (ISG) parallel hybrid drivetrain is selected as
the drive system of the hybrid electric city mercial vehicle according to its
characteristics and usage requirement. Based on the recent research of the hybrid electric
vehicle in the world, the structure of the drive system is conceptive designed, and the
parameters of the ponents puted and optimally matched by the analysis of
the system and their special characteristics.
Then, the methodology and modeling issues of the ponents were
described by making reference to the model presented in some paper. Based on
ADVISOR software, the hybrid electric vehicle of IVECO are modeled. Through the
simulation, the vehicle control strategy was realized and optimized. Another focused
point was the rear-drive vehicle model and simulation. pletion of the prototype
vehicle, dynamometer test and whole vehicle level test was done too. It partly verified
the result of simulation and a
