The invention relates to a method for operating an exhaust gas aftertreatment device (10) for cleaning an exhaust gas stream of a hybrid electric motor vehicle (2) with a drive train (4) having an internal combustion engine (6), a first electrical machine (8a) and a second electrical machine (8b), comprising the following steps: reading a value indicative of an operating mode of the hybrid electric motor vehicle (2), reading a value indicative of an operating temperature of the exhaust gas aftertreatment device (10), comparing the value indicative of the operating temperature of the exhaust gas aftertreatment device (10) with a threshold value, and activating an electrically heated catalytic converter (12) of the exhaust gas aftertreatment device (10) if the value indicative of the operating mode is indicative of an electrical operating mode and the value indicative of the operating temperature of the exhaust gas aftertreatment device (10) is below the threshold value. 本发明涉及用于操作排气后处理装置的方法，公开了用于操作排气后处理装置(10)以清
