Abstract: The invention relates to a control system for controlling a brake, a steering and/or a drive of an autonomous or automated vehicle. This involves an artificial-intelligence-based first control apparatus being monitored by virtue of a criticality of a driving situation being determined on the basis of simple calculation values, wherein a specific criticality of the driving situation, or an inappropriate reaction by the first control apparatus to the driving situation, can result in changeover to a second control apparatus that undertakes the control of the vehicle on the basis of a deterministic calculation rule.
