Abstract

A method for monitoring a control loop or a regulating loop in a system, in particular in an engine system in a motor vehicle, is described. A characteristic value is ascertained from a preset value and a system variable of the regulating loop or the control loop during one or more state changes, and an error is detected as a function of the ascertained characteristic value.
