By integrating the EPB with the ESC (Electronic Stability Control) system, parking brake
performance in the most critical conditions is now greatly improved compared to traditional
solutions: its technology is capable of estimating brake disc temperature, road slope and
other operating conditions.
The continuous diagnostics of all these variables and the system operating status by the
electronic control unit automatically ensures a second activation of braking force in the event
of a vehicle slipping. When, on the other hand, parking is carried out with very high caliper
and pad temperatures, the system calibrates the optimum power.
To ensure the highest safety level in emergency situations, Brembo has equipped its EPB
with a system that allows emergency braking with wheel anti-locking. This solution allows
the driver to stop the vehicle safely should the hydraulic circuits of the calipers or drums stop
working.
The distinctive trait of the EPB system is its combination of four elements: the control button
in the cab, the software, the electronic control unit and the specific electromechanical
actuators. Depending on the manufacturer’s requirements, the actuators can be applied to
either the brake calipers or to the drum inside the brake disc (Drum in Hat).
As this is a safety-critical system, in other words, capable of managing increasingly more
complex features, Brembo has dedicated particular attention to compliance with the
prevailing regulations. The EPB has obtained ISO 26262 certification, the standard that
regulates the use and functional safety of vehicle electrical and electronic systems.
