Claim 13:
14. The device of claim 1, wherein:
the first and second electronic control units are configured to block the switching devices of both a positive and a ground line if no electric actuator is to be supplied with current,
in a fault-free operation in accordance with predetermined criteria, specifically only one of the first and second electronic control units performs the control of at least one electric actuator,
an electronic control unit of the first and second electronic control units in a passive state is configured not to carry out an active supply of current to an electric actuator for testing purposes,
the electronic control unit in the passive state is configured to switch to an active state in the event of a fault in an active control unit of the first and second electronic control units that prevents further operation of the active control unit and, as a new active electronic control unit to assume the control of the electric actuator instead of the faulty electronic control unit from then on, and
the electronic control unit in the passive state is configured to monitor voltage levels on its leads to at least one electric actuator, to plausibility-check this monitoring with information transmitted to it by the active electronic control unit regarding a current activation of the at least one electric actuator, and to monitor a safe blocking of the current blocking device.
