POWERTRAIN SYSTEM AND
PERFORMANCE OPTIMIZATION

ABSTRACT

bination of the Hybrid Electronic Vehicle (HEV) and
electronic-control diesel engine are considered as one of the most advanced
technologies in the automobile industry. This technology has a significant
meaning faced with the world’s energy and environmental problems. After
carefully study of various typical hybrid electronic technologies, the parrelal
hybrid elctric powertrain system is proposed, which has advantages such as
simple structure, high reliability, etc.
In this paper, characters of the hybrid electronic powertrain system and
ponents are analyzed carefully. The HEV’s power requirements are
calculated out according to the theory of automobile dynamics in several
typical drive cycles.
The HEV’s simulation model is also established using the backward
simulation tool, ADVISOR. Parameters of the powertrain system are chosn
carefully analyzation of the results.
The control strategy has significant influence to the HEV’s performance.
In this paper, the HEV’s mainly drive mode is analyzed, the mainly control
strategy is established and the control strategies of the NIMH batteray, the
engine, and the ISG motor are also introduced.
The HEV’s bench test and
