3.5 Electric Power Steering (EPS)
System
The EPS system is a power steering system
directly relying on motor to provide auxiliary torque.
EPS is mainly composed of torque sensor, motor,
decelerating mechanism and electric steering
control unit (ECU).
By detecting the driver’s torque input and signals
of whole car conditions, for example, car speed
and engine speed, the ECU controls the torque
output of the assist motor in real-time manner, so
as to realize the best steering assist, ensure
flexibility at low speed and stability at high speed,
and improve driving experience and car safety.
Steering mode (apply to certain models)
There are “Comfortable” and “Sport” steering
modes. You may have to steer harder with sport
mode. “Comfortable” is the default mode of the
system. You can set the steering mode in audio
system
(please refer to Page 195)
.
ECU is equipped with warning light alarm and text
alarm.
When the Start switch is at "ON" position,
the indicator light ( ) of the electric power steering
(EPS) system will be on. After starting of the
engine for several seconds, the EPS control unit
finishes self-inspection, and then the light goes off,
indicating that the EPS system works well.
If the indicator light goes on after start of the
engine or during driving, there is fault in the EPS
system, and relevant text alarm will be shown on
the instrument cluster screen.
When fault occurs in the EPS system, park the car
in a safe place, turn off the engine and then start
the engine again. If the light is still on after re-start
or during driving, please go to your GAC MOTOR
dealer timely for repair.
