Abstract: The invention relates to a method for regenerating a particulate filter in the exhaust gas channel of a motor vehicle with a hybrid drive consisting of an electric motor and an internal combustion engine. In this context, the internal combustion engine is lugged by the electric motor in order to regenerate the particulate filter. The internal combustion engine transports oxygen-rich air into the exhaust gas channel, a process in which the soot retained in the particulate filter is oxidized by the oxygen and the particulate filter can thus be regenerated. In this process, during the regeneration of the particulate filter, the quantity of air is controlled by a throttle valve in the air supply means of the internal combustion engine in order to allow the particulate filter to be regenerated as quickly and efficiently as possible.
