ABSTRACT:
A method for operating at least one computing device and at least one monitoring circuit (watchdog) which is allocated to the at least one computing device and which is to be controlled by the computing device according to a specific temporal pattern, in particular, for a control or safety device for a motor vehicle, the computing device being reset if the monitoring circuit fails to be controlled according to the temporal pattern. To synchronize, in as easy a manner as possible, the computing device to the monitoring circuit, subsequent to a start-up of the computing device from a reset mode into a working mode, a time base may be ascertained which elapses subsequent to the start-up of the computing device until a reset of the computing device occurs due to a failure to control the monitoring circuit according to the temporal pattern, and the monitoring circuit is controlled at time intervals that are determined as a function of the time base.
