Multi Display Unit

INFOID:0000000009750186

DESCRIPTION

• The multi display unit connects to other units via CAN communica-

tion and performs the drive mode control.

• The following 3 drive modes are available, NORMAL, SPORT, and

ECO.

• The drive mode can be changed over as desired by pressing the

D-MODE select switch. The characteristics of the engine, CVT,
steering and air conditioner are changed accordingly.

• The display shows the current drive mode (NORMAL, SPORT,

ECO) as well as the vehicle information for the mode.

Part name

Description

Multi display unit

Transmits the ON/OFF status of each mode of the drive mode switch (NORMAL, SPORT, ECO) to
TCM (CVT models), ECM (M/T models), EPS control unit and the A/C auto amp via CAN commu-
nication.

ECM

Based on the mode signals received from TCM (CVT models) or multi display unit (M/T models) via
CAN communication, changes over the throttle position and other characteristics.

TCM

Based on the mode signals received from the multi display unit via CAN communication, changes
over the gear shift line and other characteristics.

EPS control unit

Based on the mode signals received from the multi display unit via CAN communication, changes
over the steering assist characteristic.

A/C auto amp

Based on the ECO mode signal received from the multi display unit via CAN communication,
changes over the set temperature correction.

SYSTEM DIAGRAM

• The multi display unit transmits the operation status of the drive mode switch to other units via CAN commu-

nication as the mode signal (refer below).

- NORMAL: ON/OFF
- SPORT: ON/OFF
- ECO: ON/OFF
• Based on the mode signals received from TCM (CVT models) or multi display unit (M/T models) via CAN

communication, ECM changes over the throttle position and other characteristics.

• Based on the mode signals received from the multi display unit via CAN communication, TCM changes over

the gear shift line and other characteristics.

• Based on the mode signals received from the multi display unit via CAN communication, EPS C/U changes

the steering assist characteristic.

• Based on the ECO mode signal received from the multi display unit via CAN communication, the A/C auto

amp changes over the set temperature correction.

CONTROL DESCRIPTION

• The drive mode switch in the controller of the multi display unit is used to change over the vehicle mode and

thus change the control characteristics for the engine, transaxle, steering, and air conditioner.

Function Apply List

• With the NORMAL mode as the base mode, the control of vehicle characteristics is changed over to the fol-

lowing modes.

- SPORT: The control characteristics for the engine, transaxle, and steering system are changed so that a

sporty feel is created in the driving behavior.

- ECO: The control characteristics for the engine, transaxle, and automatic air conditioner are changed to help

improve the practical fuel economy.

Throttle position charac-
teristic

Half open

—

Improves the engine response to acceler-
ation pedal operation and enhances the
torque feel.

—

Late open-

ing

Accelerates gently to assist in ECO driv-
ing.

Speed limiter for throttle
position

—

Controls the throttle position to a smaller
level than NORMAL to help improve the
practical fuel consumption.

TRANSAXLE

High speed gear shift
line

—

Keeps the engine speed at a high level
and improves the acceleration dynamism
and response.

Downshift upon braking

—

performs downshift upon braking before
cornering to prevent a drop in the engine
speed.

Cornering ratio hold

—

Helps the vehicle clear a curve smoothly
by restricting shift changes during corner-
ing.

Low speed gear shift line

—

Improves the practical fuel economy by
controlling the engine speed to a low level.

STEERING

Assist characteristic

—

Changes the steering assist characteristc
to enhance a stable steering feel.

AIR CONDITIONER

Air inlet control

—

Reduces the engine load by optimizing the
air conditioner control to a level that does
not adversely affect the interior comfort
and thus helps improve the practical fuel
economy.
