ABSTRACT:
The present invention provides a method and a device for controlling operational sequences, in particular in a vehicle. In this context, a functional unit for forwarding and receiving data via at least one connecting unit is in contact with at least one bus system. Functional unit is monitored by a monitoring unit. The monitoring unit prevents the forwarding of data by the functional unit via the at least one bus system if the monitoring unit detects an error of the functional unit. In an error case, in order to prevent the forwarding of data by functional unit in a manner as simple as possible, yet one that is safe and reliable, an error signal is emitted by the monitoring unit, which error signal assumes different values as a function of whether an error of the functional unit has been recognized or not, and the error signal is applied to the at least one connecting unit such that the at least one connecting unit is deactivated by the error signal if an error of the functional unit has been detected.
