A method and a device for monitoring the functioning of a system by checking input signals, output signals and at least one function unit of the system. The system includes at least one lower-level subsystem and/or is a component of a higher-level system. The system includes components implemented in the form of hardware, including sensors, actuators and/or function computers. An intended function of the system is subdivided hierarchically as a function of the complexity of the function into at least one subsystem function which is in turn subdivided into at least one function unit, and the method is structured hierarchically into multiple monitoring layers.

Method and device for monitoring the functioning of a system

A method of monitoring the functioning of a system by checking input signals, output signals, and functions of the system is provided. The system may have lower-level subsystems or may be a component of a higher-level system. The system has hardware components, including sensors, actuators, and/or function computers. A flexible structure, applicable to various systems to be monitored, is provided for the monitoring method. This monitoring method is structured into multiple decentralized monitoring functions provided in the individual functions of the system for monitoring the functioning of the individual functions, and structured into at least one higher-level, functions-overreaching monitoring instance for coordinating the monitoring functions.

The invention is directed to a method and an arrangement for controlling an operating variable of a motor vehicle wherein the controller has at least one changeable parameter. This parameter of the controller is changed in dependence upon the operating range of the actuator, which is driven by the controller, and/or the magnitude of the change of the desired value.

The invention is directed to an arrangement for the open-loop and/or closed-loop control of an operating variable of an internal combustion engine. The arrangement includes an electronic open-loop and closed-loop control unit which is influenced with an actuable positioning component operating on the operating value in dependence upon at least one operating variable. This arrangement includes at least one safety means which changes its signal condition in predetermined positions of the actuator. Devices are included for precisely determining and detecting the position of the signal condition change. These devices control the actuator in predetermined operating conditions independently of the operating variable.
