5.6 Electric power steering
(EPS)
Electric power steering system (EPS) is a
power steering system that directly relies on
the motor to provide auxiliary torque, and is
mainly composed of a TAS, a motor, an ECU
and a deceleration mechanism, etc.
The ECU controls the motor assist torque
output in real time by detecting the driver’s
torque input, vehicle speed, engine speed and
other vehicle status signals, providing the best
steering assistance, ensuring the vehicle’s low-
speed steering agility and high-speed steering
stability, and improving driving comfort and
vehicle safety.
CAUTION
After wheel alignment of the vehicle, the
position of the center point of the steering
wheel will be affected, so it is necessary
to re-calibrate the center point of the EPS
TAS.
EPS indicator lamp
When the vehicle power switch is in the
“ON” gear, the system performs self-test.
The indicator lamp will be turned off
automatically after being turned on for several
seconds, indicating that the EPS is normal.
If indicator lamp does not go out or it lights
up while the vehicle is running, this indicates
that EPS has a malfunction, and the warning
message “please check EPS” appears 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.
Turning force applied to the steering wheel
There are three modes for turning effort of
the steering wheel: Light, Comfort and Sport,
where the turning effort of the steering wheel
will be small in Light mode, moderate in
Comfort mode, and large in Sport mode. The
system is in Light mode by default. There are
two ways to select the turning effort of the
steering wheel:
Method 1:
- Select it through the AV system “Driving
mode → Current mode settings → Turning
effort of the steering wheel”.
Method 2:
- The turning effort of the steering wheel is
set automatically by switching the driving
mode (refer to chapter “4+X Driving
Mode” => See page 181 ).
CAUTION
Please select the turning effort of the
steering wheel when releasing the steering
wheel in place.
