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 moves closer to the optimum and is controlled
electronically, thus being dispensed with the need for the
proportioning valve.
The proportioning valve, because of a mechanical device, has
limitations in achieving an ideal brake force distribution to the rear
wheels as well as carrying out the flexible brake force distribution
proportioning to the vehicle load or weight increasing. And in the event
of malfunctioning, drivers cannot notice the failure.
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.
