Problems solved by technology

[0005] However, these solutions have the disadvantage that in addition the coasting phase of the internal combustion engine must be waited for in order to carry out the regeneration of the particle filter and that the particle filter is regenerated more frequently than actually necessary

Embodiment Construction

[0055] figure 1 A schematic representation of a motor vehicle with a hybrid drive is shown. The hybrid drive includes an internal combustion engine 10 and an electric motor 20 , both of which are operatively connected to a common transmission 38 . In this case, the internal combustion engine 10 and the electric motor 20 are preferably arranged transversely to the direction of travel of the motor vehicle in an engine compartment in the front of the motor vehicle. Alternatively, internal combustion engine 10 and electric motor 20 can likewise be arranged longitudinally to the direction of travel. A first clutch 22 is arranged between the internal combustion engine 10 and the transmission 38 , via which the internal combustion engine 10 can be mechanically connected to the transmission 38 . The first clutch 22 can be designed not only as a simple shift clutch but also as a preferably automated double clutch. A further clutch 36 is arranged between the transmission 38 and the e...

Abstract

The invention relates to a method and device for generation of a particle filter in an automobile with a hybrid driving past. In normal driving the automobile, carbon black particles in a stage where an internal combustion engine is activated is stored in a particle filter from the waste gas of the internal combustion engine; in order to filter and regenerate the particles, the particle filter is heated to a regeneration temperature; the motor and the internal combustion engine are connected for regeneration, and, in other words, the motor drives the internal combustion engine and the internal combustion engine is used for conveying the carbon black particles which are used for oxidation and maintained in the particle filter to a waste gas channel.

Description

technical field [0001] The invention relates to a method and a device for regenerating a particle filter in the exhaust gas tract of a motor vehicle with a hybrid drive. Background technique [0002] The continuous tightening of emission legislation places high demands on vehicle manufacturers, which are met by corresponding measures for reducing the raw engine emissions and by corresponding exhaust gas aftertreatment. With the introduction of the EU6 legislative phase, limit values ​​for the number of particles are prescribed for gasoline engines or vehicles with hybrid drives, which in many cases necessitate the use of particle filters. During driving operation, such particle filters are impregnated with soot. In order that the exhaust gas backpressure does not rise too strongly, the particulate filter has to be regenerated continuously or periodically. In order to carry out the thermal oxidation of the soot retained in the particulate filter with oxygen, sufficiently hi...
