Kia Sorento: EBD (Electronic Brake-force Distribution)
Second Generation XM (2011-2023) / Kia Sorento XM 2011-2023 Service Manual / Brake System / ESC(Electronic Stability Control) System / EBD (Electronic Brake-force Distribution)
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.
Advantages

Function improvement of the base-brake system.
|
| - |
Compensation for the different friction coefficients.
|
| - |
Elimination of the proportioning valve.
