Operation Of The Ebd Device - Fiat Bravo Service Manual

Braking system
EBD device
3 3 .
The integration of the EBD function into the normal implementation logic of the A B S system allows the
simultaneous operation of the two strategies; as a result, the system normally intervenes to keep the
"creeping" of the rear wheels within values very close to the ideal ones with the possibility, however, of
intervening w i t h the ABS strategy when one rear wheel tends to lock (for example on a surface w i t h
poor adhesion).
The graph below illlustrates the braking pressure implementation strategy, operated by the electronic
control unit, according to the input data, represented by the signal for the rotation speed of the wheels
of the t w o axles.
Operation of the E B D device
The braking pressure for the rear axle is implemented by the control unit in a similar way to the descrip-
tion of the operation of the ABS system during the pressure increase, maintenance and reduction stages.
