The EBD system (Electronic Brake Force Distribution), a
sub-system of the ABS system, controls 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 optimized and electronically controlled, thus distributing according to the need by the proportioning valve.
The proportioning valve, being 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 increased weight. Also, in the
event of malfunctioning, there is no notification of the failure to the
driver.
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 so that it doesn''t exceed that of the front wheels.
If the EBD fails, the EBD warning lamp (Parking brake lamp) lights up.
Advantages
–
Function improvement of the base-brake system.
–
Compensation for the different friction coefficients.

In principle, ESC and TCS controls are prohibited in case of ABS failure.
2.
When ESC or TCS fails, only the failed system control is prohibited.
