Abstract

A method and an apparatus for monitoring the control of operational sequences in a vehicle is described, in which context control functions are executed in a control unit, and monitoring functions that monitor the control functions are also executed. A monitoring module transfers at least one query to the control unit. A first monitoring function, in particular a sequence monitor, provided in the control unit, calculates a subresponse to the query in a second definable timing framework. The control unit creates, from at least one subresponse, a response to the monitoring module. Creation of the response is activated in a definable first timing framework. The control unit transfers the response to the monitoring module, and the monitoring module, as a function of the response, detects faults regarding execution of the control functions. The first and the second timing frameworks are asynchronous with one another.
