5.6 Electric power steering
(EPS)
The EPS is a power steering system which
directly uses the motor for providing torque.
It is mainly composed of a torque sensor, a
motor, a retarding mechanism and an electric
power steering control unit (ECU).
The EPS ECU controls the torque provided
by the EPS motor in real time by detecting the
torque applied by the driver, the vehicle speed,
the engine speed and other status signals of
the vehicle to augment the steering effort in
the best way so as to ensure the easiness of
steering at a low speed and the stability of
steering at a high speed, and to improve the
driving comfort and vehicle safety.
CAUTION
After the four-wheel alignment of the
vehicle, the midpoint of the steering angle
sensorwillbea󰀨ected,soitisnecessaryto
recalibrate the midpoint of the EPS torque
and angle sensor (TAS). The difference
between the left and right limit angles of the
steering wheel is within 20°.
EPS indicator lamp
With vehicle power switch in “ON” position, the
indicator lamp
lights up for a few seconds
and then goes out after the system completes
the self-test, indicating that the EPS works
normally.
If the indicator lamp
does not go out after
the engine is started or comes on during
driving, it indicates that the EPS is faulty, and
in the meanwhile, an alarm message indicating
“Please check EPS” will be displayed on the
instrument cluster display. In this case, it is
required to park the vehicle in a safe place,
and shut down and restart the engine. If the
indicator lamp does not go out or comes on
again while driving, stop driving, and contact
the GAC Motor authorized shop for inspection.
Steering mode
There are three steering modes: Light, Comfort
and Sport modes, where the hand force of
the driver turning the steering wheel in Light
mode will be small, in Comfort mode will be
moderate, and in Sport mode will be large. The
system is set to the Comfort mode by default.
There are two ways to select the steering
mode:
①
On the AV system interface, select
“Drivemode→Currentmodesetting→Steering
mode”;
②
If the drive mode is switched, the
system can automatically set the steering
mode (see “Drive mode”)
CAUTION
Please select the steering mode when the
vehicle keeping still and the steering wheel
is released.
