The EBD system
(Electronic Brake force Distribution) as a sub-system of the ABS system is
to control the maximum braking effectiveness by the rear
wheels.
It further utilizes the
efficiency of highly developed ABS equipment by controlling the slip of
the rear wheels in the partial braking range.
The brake force is moved
even closer to the optimum and controlled electronically, thus dispensing
with the need for the proportioning valve.
The proportioning valve,
because of a mechanical device, has limitations to achieve an ideal brake
force distribution to the rear wheels as well as to carry out the flexible
brake force distribution proportioning to the vehicle load or weight
increasing. And in the event of malfunctioning, driver cannot notice
whether it fails or not.
EBD controlled by the
ABS Control Module, calculates the slip ratio of each wheel at all times
and controls the brake pressure of the rear wheels not to exceed that of
the front wheels.
If the EBD fails, the
EBD warning lamp (Parking brake lamp) lights up.
