Abstract
In an electronic brake of a vehicle, it is to be prevented that an actuator that is arranged on each wheel of the vehicle and that comprises a self-locking mechanism effects an undesired continuous blocking of the wheel. For this purpose, an energy storage unit is arranged directly at the actuator, which, on the basis of a suitable control mechanism, ensures the release of the actuator for the respective wheel in case of failure of the current supply. In addition, given a changeover to such an emergency operation, the supply line is interrupted on the basis of a controlled switch, in order to ensure release of the actuator even in the case of a short-circuit.
