Claim 0:
1. A device for decoupling and/or protecting against compensation currents when at least one electric actuator is used jointly by a plurality of independently voltage-supplied control unit devices in redundant systems for autonomous driving, comprising:
at least one current flow blocking device, which is configured to prevent a resulting flow of current to an electronic control unit of another of a first control unit device and a second control unit device when one of the first and second control unit devices applies a switched current to the at least one electric actuator;
wherein the at least one electric actuator has, in each case, a common connection, via which the electric actuator can be coupled and switched to a common connection of other electric actuators, and has at least one dedicated connection, via which the at least one electric actuator can be individually supplied with current,
wherein the plurality of control unit devices has at least one first control unit device including a first electronic control unit and a first number of switching devices corresponding to the common connection and the number of dedicated connections of all the electric actuators, and has at least one second control unit device including a second electronic control unit and a second number of switching devices corresponding to the common connection and the number of dedicated connections of all the electric actuators, and
wherein the at least one first and second control unit devices are arranged to apply or not apply a switched current to the at least one electric actuator using the switching devices.
