9-13 Electric power steering system
Supply steering power according to speed
UTV's steering power can change as
different various speeds and steering angle.
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
make UTV U-turn or stop into place as much
as possible to ease the steering operation.
With increased speed, reduce power torque
can make UTV 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
