Overview ofDevelopment on Vehicle EPS System
Abstract
The currentdevelopment of an electric power steering(EPS) system
in an automobile is explicated. The
structure, types and characteristics
of
electric
power
steering
system
are
introduced.
The
modeling
technologies
for
electric
power
steering
system
and
control
strategies
are
analyzed
and
compared.
The
development
trend
of
electric
power
steering
system in an automobile is also discussed. It is pointed that the
electric power steering technology is one orientation ofpower
steering
technologies in the future, and whichwill occupy a predominantposition
in power steering field.
