Abstract: A switching device for a vehicle brake system, including: a central-control-unit (CCU) for controlling the brake system, at least one subsystem-control-unit (SCU) which is connected/connectable to the CCU via a data bus to control a subsystem device of the brake system and/or a redundant-control-unit (RDC) which is connected/connectable to the CCU via a further data bus to control a redundant brake system for the brake system; and a monitoring device to read in a first test signal from the CCU to test a function of the CCU and which is configured to read in a second test signal from the SCU to test a function of the SCU and/or to read in a redundant test signal from the RDC to test a function of the RDC. Also described are a related brake system, a method, and a computer readable medium.

Abstract: 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.

Abstract: A method for controlling at least one actuator of an actuator system, including: outputting a first control signal from a first control device via a line to an actuator, wherein the actuator system has at least the first control device and a second control device, wherein the first control device is configured to control at least the actuator via the line and wherein the second control device is configured to control the actuator via the line; detecting the first control signal on the line by the second control device and suppressing the output of a second control signal to the actuator by the second control device during a time in which the first control device is outputting the first control signal to the line; determining a time by the second control device at which no first control signal is present on the line; and applying to the actuator a second control signal via the line by the second control device if no first control signal is present on the line.

Abstract: A device for controlling a current of an actuator, including: at least one control unit having a first terminal; a first switch; a second terminal; and a second switch for controlling a flow of current through the actuator via the first terminal and the second terminal independently of one another; a first current measuring apparatus for measuring a first current through the first terminal; and a second current measuring apparatus for measuring a second current through the second terminal; in which the first current measuring apparatus and the second current measuring apparatus are integrated into the at least one control unit so that fault currents can be acquired. Also described are a related electronic control unit, a commercial vehicle, and a method.
