Abstract
A method is presented for operating a safety-critical controller, wherein the controller monitors correct functioning of the controller, of at least one sensor or at least one actuator, or a plurality of these, and where specific error conditions exist a warning for the driver is generated, wherein for at least a subgroup of error conditions as a warning an appropriate warning message is given to the driver. If within a specified time span no clearance of the error has been detected, a corresponding data transmission to a vehicle manufacturer and/or service provider takes place, wherein the time span is preferably extended if the driver confirms the warning message by operating a corresponding operating means.
