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.

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

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
