ABS FUNCTION : System Description

INFOID:0000000011280573

• By preventing wheel lock through brake force (brake fluid pressure) control that is electronically controlled by

detecting wheel speed during braking, stability during emergency braking is improved so that obstacles can

be easily bypassed by steering operation.

• During braking, control units calculates wheel speed and pseudo-vehicle speed, and transmits pressure

increase, hold or decrease signals to actuator portion according to wheel slip status.

• The following effects are obtained by preventing wheel lock during

braking:

- Vehicle tail slip is prevented during braking when driving straight.

- Understeer and oversteer tendencies are moderated during brak-

ing driving on a corner.

- Obstacles may be easily bypassed by steering operation during

braking.

• CONSULT can be used to diagnose the system diagnosis.

• Fail-safe function is adopted. When a malfunction occurs in ABS

function, the control is suspended for VDC function, TCS function,

ABS function, Brake limited slip differential (BLSD) function, Brake

assist function, hill start assist function and Brake force distribution

function. The vehicle status becomes the same as models without

VDC function, TCS function, ABS function, Brake limited slip differ-

ential (BLSD) function, Brake assist function, hill start assist func-

tion and Brake force distribution function. However, EBD function

is operated normally. Refer to 

BRC-20, "Fail-Safe"

.

NOTE:

• ABS has the characteristic as described here, This is not the

device that helps reckless driving.

• To stop vehicle efficiently, ABS does not operate and ordinary

brake operates at low speed [approx. 10 km/h (6 MPH) or less, but

differs subject to road conditions).

• Self-diagnosis is performed immediately after when engine starts

and when vehicle initially is driven [by vehicle speed approx. 15 km/h (9 MPH)]. Motor sounds are generated

during self-diagnosis. In addition, brake pedal may be felt heavy when depressing brake pedal lightly. These

symptoms are not malfunctions.

INPUT SIGNAL AND OUTPUT SIGNAL

Major signal transmission between each unit via communication lines is shown in the following table.

EBD FUNCTION
EBD FUNCTION : System Description

INFOID:0000000011280574

• By preventing rear wheel slip increase through rear wheel brake force (brake fluid pressure) control that is

electronically controlled when slight skip on front and rear wheels are detected during braking, stability dur-

ing braking is improved.

• EBD function is expanded and developed from conventional ABS function and corrects rear wheel brake

force to appropriate level by electronic control according to load weight (number of passengers).

• During braking, control unit portion compares slight slip on front

and rear wheels by wheel speed sensor signal, transmits drive sig-

nal to actuator portion when rear wheel slip exceeds front wheel

slip for the specified value or more, and controls rear wheel brake

force (brake fluid pressure) so that increase of rear wheel slip is

prevented and slips on front wheel and rear wheel are nearly

equalized. ABS control is applied when slip on each wheel

increases and wheel speed is the threshold value of ABS control or

less.

• CONSULT can be used to diagnose the system diagnosis.

• Fail-safe function is adopted. When a malfunction occurs in EBD

function, the control is suspended for VDC function, TCS function,

ABS function, EBD function, Brake limited slip differential (BLSD)

function, Brake assist function, hill start assist function and Brake

force distribution function. The vehicle status becomes the same

as models without VDC function, TCS function, ABS function, EBD

function, Brake limited slip differential (BLSD) function, Brake

assist function, hill start assist function and Brake force distribution

function. Refer to 

BRC-20, "Fail-Safe"

.

BRAKE LIMITED SLIP DIFFERENTIAL (BLSD) FUNCTION
BRAKE LIMITED SLIP DIFFERENTIAL (BLSD) FUNCTION : System Description

INFOID:0000000011280575

• LH and RH driving wheel spin is always monitored. If necessary, appropriate brake force is independently

applied to LH or RH driving wheel so that one-sided wheel spin is avoided and traction is maintained. Mainly

starting ability is improved.

• Brake limited slip differential (BLSD) function operates while VDC function is in non-operational status (OFF)

by VDC OFF switch.

• VDC warning lamp blinking while Brake limited slip differential (BLSD) function is in operation and indicates

to the driver that the function is in operation.

• Slight vibrations are felt on the Brake pedal and the operation noises occur, when Brake limited slip differen-

tial (BLSD) function operates. This is not a malfunction because it is caused by Brake limited slip differential

(BLSD) function that is normally operated.

• Fail-safe function is adopted. When a malfunction occurs in brake limited slip differential (BLSD) function,

the control is suspended for VDC function, TCS function, Brake limited slip differential (BLSD) function,

Brake assist function, hill start assist function and Brake force distribution function. The vehicle status

becomes the same as models without VDC function, TCS function, Brake limited slip differential (BLSD)

function, Brake assist function, hill start assist function and Brake force distribution function. However, ABS

function and EBD function are operated normally. Refer to
