An apparatus for providing a sensor signal (SS) for evaluating a vehicle braking system, including: a first signal-path (SP) for outputting the SS to a first output-interface (OI) to a first converter-device (CD), the first SP having first electronic-components (EC), and is electrically connectable to an input-interface (II) to a vehicle sensor (VS); a first test-device (TD) for applying a first test-signal (TS) to the SS in the first SP, the first TD being electrically connectable to the first SP; a second SP for outputting the SS to a second OI to a second CD, the second SP having second EC, and is electrically connectable to the II to the VS; and a second TD for applying a second TS to the SS in the second SP, the second TD being electrically connectable to the second SP. Also described are a method, control unit, braking system, and computer readable medium.

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.

A circuit arrangement for detecting a solenoid valve type in vehicles, including at least one solenoid valve in the circuit arrangement for detecting the solenoid valve type and having at least one coil winding having a resistance of the typical order of magnitude for a predetermined vehicle electrical distribution system supply voltage, a constant current source, arranged to impress a predetermined measurement current into the one coil winding of the solenoid valve, a current mirror circuit, arranged to generate a second voltage on a detection section of the circuit arrangement from a first voltage produced as a result of the impressed measurement current on the at least one coil winding of the at least one solenoid valve, in which the second voltage produced on the detection section is passed out, on the detection section, directly to a microcontroller in a control device for determining the type of solenoid valve.
