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.
