Abstract

A backup system (100) for an electronic parking brake, EPB, of a commercial vehicle to ensure a safe state even during electric power failure of a power supply unit (50) of the EPB, includes: a detection unit (110) for detecting the power failure; a storage device (120) for storing sufficient electric power to perform a switch into the safe state; a boost circuit (130) configured to charge the storage device (120) during standstill of the vehicle and to discharge the storage device (120) during motion of the vehicle; and a switch device (140) configured to supply the electric power of the storage device (120) to the EPB if the power failure is detected by the detection unit (110).
