Abstract: A device for control of a safety-relevant process. For automated driving, safety precautions are necessary. The brake system is a redundant design including primary and secondary brake systems. Both brake systems safely decelerate the transportation vehicle and take over the function of the other brake system. The control of the safety-relevant process is based on the analysis of the signals of at least one sensor. A hardware architecture and a test mode for the hardware architecture are provided. A communications bus enables exchange of data between the primary and secondary control units. The at least one sensor of the hardware architecture connects to the primary control unit and to the secondary control unit, wherein a respective sensor arrangement isolation circuit is associated with the primary control unit and the secondary control unit, which isolates the associated primary or secondary control unit from the at least one sensor.
