Abstract

A system for controlling a regulator equipped with an electric servomotor in a motor vehicle. With reference to an example of an electronic steering system that has an electric-motor steering regulator, output parameters are generated by a model-assisted monitor for evaluating the suitability of a correction for the regulator, and thus criteria for a possible shutdown or to initiate emergency action, as a function of setpoint parameters for the electric servomotor, of instantaneous parameters measured by individual sensors, and of the driving state, and, based on a setpoint behavior of the regulator and on a model simulating the control sections it contains.
