Abstract
Various embodiments include a control device for a vehicle with an internal fault monitoring circuit comprising: a safe computing unit executing a monitoring function for monitoring the safe computing unit and the monitoring function; and an unsafe computing unit executing the monitoring function. Monitoring the monitoring function of the safe computing unit changing the operation of the monitoring function of the safe computing unit to induce faults in the monitoring function of the unsafe computing unit. The monitoring function of the unsafe computing unit detects the induced faults in the operation of the monitoring function of the safe computing unit and reports the induced faults to the monitoring of the monitoring function of the safe computing unit.
