Electric Power Steering System

Check the meter. If fault indicator light of EPS
system is not lit, ECU is ready for regular use.
If fault indicator light of EPS system is lit, that
means EPS system found a fault during the
ECU self-checking process, then you should
consult your local dealer for maintenance.

DANGER
Driving the UTV with faulty EPS system may cause
an accident, severe injury or even death.
Never operate UTV with faulty EPS system.
■
Function of EPS system
EPS system requires enough power to supply
correct power torque.
Supply Power steering according to speed
UTV’s power steering can change at different
speeds and steering angles.
The EPS systems can supply different power
torque depending on the speed and steering
angle.
①
T1
：
steering resistant torque which is checked by
steering power sensor
②
T2
：
power torque on steering gear which is
supplied by EPS system
③
Power Torque In Static Condition
④
Power Torque At Middle Speed
⑤
Power Torque At The Highest Speed
Stationary, the maximum power torque can
assist a turn while stopped in place as much
as possible to ease the steering operation
.
With increased speed, reduce power torque
can assist steering at high speed, to make ii
easier to maintain driving direction.
As shown, power auxiliary effect depends not
only on speed, but also steering torque
exerted by the driver. If the driver is to impose
a smaller steering torque, power torque of the
EPS system will be relatively small. This can
be achieved outstanding auto-centering effect,
that means when the UTV is in a straight-line,
the steering system will not be as sensitive
(the steering wheel does not move from side
to side).
