ELECTRONIC CONTROL AWD

27C-2

GENERAL INFORMATION

M1272000100103

• Electronic control AWD has been adopted to

ensure the on-road performance, achieve lighter
and smaller body, and realize better fuel econ-
omy.

• The electronic control AWD controls the torque of

the electronic control coupling located between
the propeller shaft and rear differential. This strat-
egy is enabled by varying the torque distribution
to the front and rear wheels from the status closer
to the front wheel drive to the status closer to the
direct coupling AWD and realizes the optimal
drive force according to the various driving condi-
tions.

.

AIMS OF DEVELOPMENT

Lightweight and simple construction of the electronic
control AWD achieves good fuel efficiency and pro-
vides enjoyment of selecting the drive mode.

.

FUNCTION

• The adoption of the electronic control coupling

satisfies both of the tight corner braking phenom-
enon

*

and traction performance.

NOTE:

*

Tight corner braking indicates the follow-

ing condition. When the AWD vehicle turns
sharply on a pavement at low speed (ex. parallel
parking), the rotational radius of the front and rear
wheels differs, and this difference can no longer
be compensated by the tire slippage. At this time,
the driver feels as if the brake was applied.

• The electronic control AWD receives the signals

of the throttle position and vehicle speed via
CAN

*

communication protocol, detects the vehi-

cle driving condition and operation of the driver,
and distributes the proper torque to the rear
wheels.

NOTE:

*

: For more information about CAN (Con-

troller Area Network), refer to GROUP 54C .

• Under severe driving condition, the system is pro-

tected by minimizing the limitation force of the dif-
ferential.

• During high-speed driving, the fuel efficiency is

improved by reducing the limitation force of the
differential.

• The following drive modes are available accord-

ing to the drivers' preference to provide the enjoy-
ment of selecting functions.

Control content

Appeal points

FWD
(2WD)

Minimizes the
limitation force of
the differential.

High fuel efficiency
mode which enables
smoother turning
performance of the
FF vehicle

AWD
(4WD)

Increases the
limitation force of
the differential
according to the
different rotation
speed of the front
and rear wheels
and the throttle
position.

Universal mode
which automatically
distributes the drive
force to the rear
wheels as necessary

LOCK

Further increases
the limitation force
of the differential
compared to the
AWD mode.

Mode which has an
excellent driving
performance when
driving on rough road
or in stuck situation
and enables the
powerful driving
