A method is provided for controlling an internal combustion engine as a function of an expected value of a temperature of a component of an exhaust gas system, route data of an expectable driving route being assigned values of exhaust gas temperatures. The method is characterized in that the route data are assigned engine operating data which are expectable when passing through the expectable driving route and in that a first exhaust gas temperature expected value is computed and assigned to a route section, in that the route is subdivided into characterizable route sections, in that each of these route sections is assigned a predetermined second exhaust gas temperature expected value which is based on at least one exhaust gas temperature value measured at an earlier point in time, and in that the expected value of the temperature of the component is formed on the basis of linking the first exhaust gas temperature expected value to the second exhaust gas temperature expected value.
