DEVICE FOR DECOUPLING AND PROTECTION FROM COMPENSATION CURRENTS IN A REDUNDANT SYSTEM FOR AUTONOMOUS DRIVING

DRIVE March 24, 2022
Source
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. The 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 electrical actuators, and has at least one dedicated connection via which the at least one electric actuator can be individually supplied with current. A number of switching devices corresponding to the common connection and the number of dedicated connections of all the electric actuators is arranged to apply or not apply a switched current in the at least one electric actuator. Provided is at least one current flow blocking device configured to prevent an unwanted current flow to a non-active electronic control unit of the first and second control unit devices.
