Abstract:
An electronic digital device for controlling vehicle processes, comprising:at least one redundant and non redundant components, an arithmetic unit, a bus connecting the at least one redundant and non redundant components, one redundant memory, wherein said bus includes at least two busses that are redundant and at least one bus that is not redundant and wherein the at least one non-redundant component is connected to one of the redundant busses, a transmission device is provided, which transfers the data exchange of the non-redundant component from one redundant bus to another redundant bus, a redundant monitoring device that compares the data arising in the redundant components and emits an error signal when the data deviate from one another, wherein the monitoring device includes a comparator implemented by means of hardware, which is connected to data lines of the redundant busses and compares the data on the busses with one another, and wherein the comparator compares the data on the redundant busses with one another whenever the data on the busses are valid.
