ELECTRONIC BRAKE FORCE DISTRIBU-
TION SYSTEM (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 syst em has the following features:
•Because the system p rovides t he optimum rea r
wheel braking force regardless of vehicle load
co ndition a nd the condition of the road surface,
the system reduces the required pedal depre s
-
sion fo rce, particularly wh en th e veh icle is h eavily
lo aded o r driven on road surfaces with high fric
-
tional coef ficients.
•Because the duty place d on th e front brakes is
redu ced, th e increase in p ad tempe rature can be
controlled d uring brake s ap plication to impro ve
the we ar resist ance characteristics of the pad.
•Contro l valves such as the propo rtioning valve
are not required.

•The

fun ctio ns. By the integra ted control with th e
ant i-lock b rake system, the system stabilizes th e

•When the st ability control fun ction dete rmin es
tha t the vehicle is in a dangerou s condition, it
redu ces the e ngine outpu t and a pplies b rake
force to f our wheels indepe ndently to control th e
