ENGINE CONTROL

GENERAL INFORMATION

M2170001001522

For the accelerator system, an electronic throttle
valve control system has been adopted, eliminating
of an accelerator cable.

This system detects the amount of the accelerator
pedal movement by using an accelerator pedal posi-
tion sensor in the accelerator pedal assembly for
electronically controls the throttle valve.

CRUISE CONTROL SYSTEM

GENERAL INFORMATION

M2170001001555

The cruise control system, which provides the con-
stant speed driving without depressing the accelera-
tor pedal at a vehicle speed determined by the driver
(within the range from approx. 40 to 200 km/h).

• For this cruise control system, in conjunction with

the electronic throttle valve control system, the
engine-ECU electronically controls the throttle
valve. <Petrol engine>

• For this cruise control system, due to the adop-

tion of the common rail fuel control system, the
engine-ECU electrically controls the fuel injection
system. <Diesel engine>

• In the situation that a vehicle speed is gradually

increased without driver’s intention on downhill

etc, speed limiter

*

is a driver assist function to

prevent from exceeding the speed set by driver.

NOTE:

*

: Adjustable speed limiter

COMPONENTS AND FUNCTIONS

Component

Function

ABS-ECU <Vehicles without ASC> or
ASC-ECU <Vehicles with ASC>

Outputs the cruise control cancel signal to the engine-ECU.

Accelerator pedal position sensor

Informs the engine-ECU of the accelerator pedal depression.

Cruise control indicator lamp <standard
meter> or cruise control display screen
<high contrast meter>

When the cruise control ON/OFF switch is pressed, a lamp will
illuminate or a screen will be displayed to inform the driver that
the cruise control system is active.

Speed limiter display screen

When the speed limiter ON/OFF switch is pressed, a screen will
be displayed to inform the driver.

Cruise control
switches

Cruise control ON/OFF
switch

Power switch for cruise control system.

Speed limiter ON/OFF
switch

Turn ON/OFF the speed limiter.

RES + switch

• Vehicle speed is set with the RES + switch and SET − switch.

• Set vehicle speed of speed limiter is set with the RES +

switch and SET

− switch.

SET

− switch

CANCEL switch

• Cancels the constant speed driving.

• Cancel speed limiter in the activated mode.

CVT-ECU <Petrol engine>

• Controls the CVT based on the CVT control signal from the

engine-ECU.

• The selector lever "N" position signal from the inhibitor switch

is sent to the engine-ECU.

• Outputs the signal from the secondary pulley speed sensor to

the engine-ECU.

A/T-ECU <Diesel engine>

• Controls the automatic transmission shifting based on the

shift control signal from the engine-ECU.

• The selector lever "N" position signal from the inhibitor switch

is sent to the engine-ECU.

• Outputs the signal from the secondary pulley speed sensor to

the engine-ECU.

Diagnosis connector

If the M.U.T.-III is connected, the diagnosis code and data list
from the engine-ECU can be read.

CONSTRUCTION AND OPERATION

M2170002000919

The cruise control section in engine-ECU calculates
the cruise control system operation condition based
on the signals sent from switches and sensors.
Based on the calculation, the cruise control section
outputs the target accelerator pedal opening angle
signal to the engine control section, and CVT control
signal to CVT-ECU <Petrol engine>, shift control sig-
nal to A/T-ECU <Diesel engine> or clutch switch
<M/T> and cruise control status (ON/OFF, etc.) to the
combination meter, respectively.

• In the engine control section, the target throttle

valve opening angle is calculated based on the
target accelerator pedal opening angle signal
from the cruise control section and the actual
accelerator pedal opening angle signal from the
accelerator pedal position sensor, and the vehicle
speed is controlled by operating the throttle valve
control servo. <Petrol engine>

• In the engine control section, the amount of fuel

consumption is calculated based on the target
engine torque signal from the cruise control sec-
tion and the actual accelerator pedal opening
angle signal, and the vehicle speed is controlled
by controlling the fuel injection system. <Diesel
engine>

Engine-ECU

• Based on the input signal from each sensors and switches,

the throttle opening angle indication signal is sent.

• Based on the input signal from each sensors and switches,

the CVT control signal is sent to the CVT-ECU. <Petrol
engine>

• Based on the secondary pulley speed sensor signal from the

CVT-ECU, it calculates the vehicle speed. <Petrol engine>

• Based on the selector lever "N" position signal from the

CVT-ECU, it cancels constant speed driving. <Petrol engine>

• Based on the input signal from each sensors and switches,

the CVT control signal is sent to the A/T-ECU. <Diesel
engine>

• Based on the secondary pulley speed sensor signal from the

A/T-ECU, it calculates the vehicle speed. <Diesel engine>

• Based on the selector lever "N" position signal from the

A/T-ECU, it cancels constant speed driving. <Diesel engine>

• To the cruise control indicator lamp, the cruise control system

ON/OFF signal is sent.

• The diagnosis codes and data list of the cruise control system

is sent to the diagnosis connector.

Inhibitor switch <CVT, A/T>

The constant speed driving is cancelled by the selector lever
operation, the "N" position is detected.

Clutch switch <M/T>

Because the constant speed driving is cancelled by the clutch
operation, the clutch pedal status is detected.

Stop lamp switch

• The constant speed driving is cancelled by the brake

operation, the brake pedal operation is detected.

• As for the stop lamp switch, two built-in switches, the stop

lamp switch which is also used for the stop lamp illumination
and the brake switch which is used exclusively for the cruise
control, are integrated, and thus the reliability is enhanced.

Throttle valve control servo <Petrol
engine>

The throttle valve opens and closes in response to the throttle
angle control signal from the engine-ECU.

Throttle position sensor <Petrol engine>

Informs the engine-ECU of the throttle valve opening angle.

Fuel injection system <Diesel engine>

Amount of fuel consumption control signal from engine-ECU.
