Method and device for temperature management of an exhaust gas aftertreatment system of a pollutant-emitting motor vehicle

摘要

A method for controlling a heat source (100, 140) for a component (130) of an exhaust system of a drive (100) of a motor vehicle is described. The method comprises (a) providing (S103) information about a future travel route of the motor vehicle; (b) determining (S106, S107) a time sequence of a plurality of temperature values in the component (130) within a predetermined future time period, wherein the time sequence is based on the information provided; (c) determining (S108, S109, S110, S111) a point in time within the time segment on the basis of the determined chronological sequence, wherein a temperature value of the plurality of temperature values which is associated with the point in time is to meet a predetermined criterion; and (d) actuating (S112) the heat source (100, 140) before the point in time so that the temperature value fulfills the predetermined criterion at the point in time. A control unit (150) for carrying out the method and a motor vehicle are also described.
