Fuse for vehicle with EPS

The vehicle with EPS has EPS fuse (80A)
mounted to the positive (+) terminal of the
battery not in the fuse box.

EPS unit

The ECU controls the electric power
steering system depending on the driving
conditions, based on the signals from the
torque and angle sensor.

HECU (Hydraulic & Electronic Control Unit)

HECU for ABS

HECU for EPS

The HECU (Hydraulic & Electronic Control Unit) determines the slip conditions of vehicle wheels by
calculating each wheel's speed and the increment/decrement of speed based on the information
detected by the sensors, and controls the pumping and boosting/reducing/keeping pressure by
operating the valve and motor of HECU.

Steering wheel angle sensor (SWAS)

The steering wheel angle sensor is mounted between
the steering column and the steering column shaft. It is
commonly used by the ESP (Electronic Stability
Program) system. And it receives signals of the steering
wheel angle sensor from the ESP HECU (Hydraulic &
Electronic Control Unit).

G-sensor(4WD, ABS)

For the vehicle with the ABS, a speed difference
between the wheels is not noticeable as all the
wheels are slipping during abrupt braking.
Therefore, the vehicle needs the speed information
from other sensors other than the wheel speed
sensor. The longitudinal acceleration sensor (G-
sensor) is used for this case. It controls the ABS by
using the signals from the sensor during abrupt
braking and acceleration.

TCU unit

The transmission control unit (TCU) is installed under
the driver seat, and controls the transmission. The
TCU is operated by the ignition power supply and
receives and processes the following information from
the inner sensors through CAN buses.

E-coupling unit

The E-coupling unit is a control unit which
determines the magnetic force by
considering CAN signals (wheel speed,
engine torque, pedal opening, ABS/ESP
CAN signals, etc.) from other ECUs.

TGS Lever assembly

The TGS communicates with TCU
(Transmission Control Unit), ECU,
ESP HECU and instrument cluster
to let the driver select the desired
transmission gear and to maintain
the desired driving condition. Also,
the tip switch is installed on the
lever knob and the steering wheel
so that the driver select the gear
manually when the shift lever is in
"M".

Sensor cluster

The sensor cluster is linked to
the sensors on the unit board
and CAN interface. And they
are housed in one case and
mounted to the body.

A/T assembly

Automatic transmission is available as 4WD- and 2WD-type,
and provides 6 speeds for forward travel and 1 reverse
travel. It is also equipped with the torque converter with inner
lock-up clutch and electronically controlled solenoid which
controls all hydraulic functions.

3. CHASSIS COMPONENT LAYOUT

PTU (Power Transfer Unit)

The PTU is a device that transfers the power
generated from the engine to the rear axle through
propeller shaft and E-coupling by changing the power
flow direction by 90° in the front wheel drive type
4WD vehicle.

Rear axle assembly

The rear axle installed in this car is a removable
axle, called IRDA (Independent Rear Differential
Axle). The rear differential carrier is installed
directly on the sub frame, and there is an
independent suspension that allows each wheel
on the same axle to move vertically independently
of each other with the universal joint and the slip
joint.

E-coupling control unit (E-Coupling ECU)

The E-coupling unit is a control unit which determines
the magnetic force by considering CAN signals (wheel
speed, engine torque, pedal opening, ABS/ESP CAN
signals, etc.) from other ECUs.

M6LF1 manual transmission

M6LF1 manual transmission is a model modified from the
one that used in other vehicle so that it can be applied to FF
(Front engine-Front wheel driving) type vehicle, and has an
axle in one piece. The engine torque and gear ratio of this
transmission have been optimized to maximize driving
performance. It provides 6 speeds for forward travel and 1
reverse travel.

Clutch assembly

M6LF1 manual transmission is a model modified from the
one that used in other vehicle so that it can be applied to FF
(Front engine-Front wheel driving) type vehicle, and has an
axle in one piece. The engine torque and gear ratio of this
transmission have been optimized to maximize driving
performance. It provides 6 speeds for forward travel and 1
reverse travel.

The 2WD vehicle with manual transmission is a front wheel drive type vehicle that doesn't have PTU,
propeller shaft, E-coupling and rear axle which are applied to 4WD vehicle. Its under structure is very
simple.
