Abstract

An electronic digital device for controlling or adjusting processes in a motor vehicle has several components, of which at least one arithmetic unit and a bus connecting the components are redundant. At least one component is not redundant. The electronic device can exhibit a preferably redundant monitoring device which compares the data arising in the redundant systems and outputs an error signal when the data deviate from one another.
