GENERAL INFORMATION
ANTI-SKID BRAKE SYSTEM (ABS)35B-2
GENERAL INFORMATION
M2351000100409
FEATURES
The ABS ensures directional stability and controlla-
bility during hard braking.
For vehicles with this type of ABS, 4 sensors (4
channels) are installed on front and rear wheels
allowing independent left and right control.
The system has the following features:
•EBD (Electronic Brake-force Distribution system)
control has been added to provide the ideal brak
-
ing force for the rear wheels.
•Magnetic encoder for wheel speed detection has
been installed as a sensing device instead of the
rotor.
•For wiring harness saving and secure data com-
munication, CAN* bus has been adopted as a
tool of communication with another ECU.
NOTE: *: For more information about CAN (Control-
ler Area Network), refer to Group 54C, General Infor-
mation P.54C-2.
EBD CONTROL
In ABS, electronic control is used so the rear wheel
brake hydraulic pressure during braking is regulated
by rear wheel control solenoid valves in accordance
with the vehicle's rate of deceleration, and the front
and rear wheel slippage which are calculated from
the signals received from the various wheel speed
sensors. EBD control provides a high level of control
for both vehicle braking force and vehicle stability.
The system has the following features:
•Because the system provides the optimum rear
wheel braking force regardless of vehicle load
condition and the condition of the road surface,
the system reduces the required pedal depres
-
sion force, particularly when the vehicle is heavily
loaded or driven on road surfaces with high fric
-
tional coefficients.
•Because the duty placed on the front brakes is
reduced, the increase in pad temperature can be
controlled during brakes application to improve
the wear resistance characteristics of the pad.
•Control valves such as the proportioning valve
are not required.
