9-27 Electric power steering system
includes a chassis
customers may use" Deviation" to describe a
specific situation. So four wheel alignment
need to be adjusted at first time, then ECU
replacement and repair needed.
2. The Fault of closing function
The main objective to research and develop
EPS system is needed to ensure that the
vehicle is still controlled by driver when
malfunction happened. Therefore we will not
allow any directions
counterclockwise) suddenly appear bigger
undesirable steering torque.
Therefore, the EPS system has many
monitoring function, used to identify the
sensor, actuator and the involvement of the
EPS system function
mechanical failure,
(clockwise or
whether is
malfunctioning. All
reliable accurate control motor malfunction
will lead to the interruption of motor control
ECU, then closed function of EPS system.
Close the EPS system's bad results will also
cause the driver can not obtain power
steering.
But close measure is mainly used for
preventing error control motor.
When fault occurs, power steering disappear
is a predetermined EPS system response
characteristic. Although the driver may feel
the characteristics of some accidents, but
increases the control force, can ensure the
vehicle steering performance is not affected.
Neither the EPS steering system nor
hydraulic power steering system, when fault
occurs, power steering will disappear. When
cannot continue to
