SWITCHING DEVICE FOR A BRAKE SYSTEM FOR A VEHICLE, BRAKE SYSTEM WITH A SWITCHING DEVICE AND METHOD FOR OPERATING A SWITCHING DEVICE

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.
