Patent ID: 11897489

Abstract:
A device for decoupling and/or protecting against compensation currents when at least one electropneumatic actuator is used jointly by a plurality of independently voltage-supplied control unit devices in redundant systems for autonomous driving. The electropneumatic actuator has, in each case, a common connection, via which the electropneumatic actuator can be coupled and switched to a common connection of other electropneumatic actuators, and has at least one dedicated connection via which the at least one electropneumatic actuator can be individually supplied with current. Switching devices, corresponding to the common connection and the number of dedicated connections of all the electropneumatic actuators, are arranged to apply or not apply a switched current in the at least one electropneumatic actuator. Provided is at least one current flow blocking device to prevent an unwanted current flow to a non-active electronic control unit of the first and second control unit devices.
