  • Patent number: 10934908
    Abstract: The invention relates to a method for regenerating a particle filter (74) in an exhaust system (60) of a motor vehicle (10) having an internal combustion engine (12). Here, for a temperature increase to a temperature (T) required for the regeneration of the particle filter (74), a sorption agent container (102) of a fuel tank (22) of the motor vehicle (10) is purged, and the fuel vapours (24) retained in the sorption agent container (102), in particular an activated carbon filter, are supplied directly or indirectly to the exhaust system (60) upstream of the particle filter (74). By means of an exothermic conversion of the fuel vapours (24) in the exhaust system (60) upstream of the particle filter (74), the exhaust-gas temperature (T) can be increased without the need for engine-internal measures for increasing the exhaust-gas temperature.

  • Patent number: 10934912
    Abstract: The invention relates to a method for the exhaust aftertreatment of an internal combustion engine, which on the outlet side is connected to an exhaust gas system. Provided in the exhaust gas system is at least one exhaust aftertreatment component with which, upon reaching the light-off temperature of this exhaust aftertreatment component, the gaseous limited exhaust gas components may be converted into unlimited exhaust gas components. An introduction point is provided at an exhaust duct of the exhaust gas system, at which a hot gas, in particular an exhaust gas of an exhaust gas burner, is introduced into the exhaust duct. The hot gas mixes with the exhaust gas of the internal combustion engine in such a way that a hot mixed gas results in which the unburned exhaust gas components are oxidized to unlimited exhaust gas components, without a catalytically active surface.

  • Publication number: 20210054793
    Abstract: A method for determining the cylinder air-charge of an internal combustion engine in a non-fired operation, wherein a method for determining the cylinder air-charge in a fired operation is performed. According to the invention, provision is made that in the method for determining the cylinder air-charge in the fired operation, a correction factor is provided as a function of engine speed and engine load which adjusts the value of the cylinder air-charge determined by the method in the fired operation to the non-fired operation. Thus, the previously known methods can be improved and made more efficient, in particular in view of the deviations of up to 30% between the cylinder air-charge values in the non-fired operation and the modeled values of the fired operation.

  • Publication number: 20210046822
    Abstract: Technologies and techniques for calculating an overlay of additional information for a display on a display unit. The overlay of additional information may support the driver in the longitudinal control of a vehicle. The overlaying of the additional information may be configured in the form of augmented reality such that it is calculated in a contact analogue manner in relation to one or more objects in the environment of the vehicle. When approaching a vehicle, a spatially extended animation graphic is calculated, wherein the animation graphic has a grid shape consisting of a plurality of grid elements, which extends from the observer vehicle up to the oncoming or preceding vehicle. The spatial extension is calculated such that the driver of the observer vehicle (10) has the impression of a kinematic or dynamic movement of the spatial extension, such as translation and rotation.

  • Patent number: 10918987
    Abstract: A particulate filter for exhaust-gas aftertreatment in an internal combustion engine has a housing on which an inlet and an outlet are configured on opposite ends. The particulate filter also has a filter element arranged in the housing, said filter element having essentially parallel filter channels that are each alternatingly closed on the inlet side or on the outlet side by a closure in order to prevent gas from passing directly through the filter element. In this context, the filter channels can be divided into a first group of filter channels which are closed on the outlet side by a closure, and into a second group of filter channels which are closed on the inlet side by a gas-tight closure. The filter channels of the second group are additionally closed on the outlet side by a high-porosity closure in order to improve the cleaning effect of the particulate filter.

  • Publication number: 20210039663
    Abstract: A method for selecting a driving profile of a motor vehicle, a driver assistance system therefor and a motor vehicle equipped therewith is disclosed. In the method and based on an operating action by a driver, a deviation between the number of predetermined driving profiles currently desired by the driver and that previously used is recognized. After the deviation has been recognized, a query is output to the driver as to whether the deviation should be taught by the driver assistance system for the current situation. After the query has been confirmed by the driver, the driver assistance system is accordingly adapted for the current situation in at least one parameter influencing the selection of the driving profile to be used such that the deviation in the automatic selection of the driving profile to be used in future situations that correspond to the current situation is taken into account.

  • Patent number: 10913446
    Abstract: A method for operating a serial-parallel hybrid powertrain of a motor vehicle has the steps of mechanically decoupling the internal combustion engine from the wheels of the motor vehicle, accelerating the motor vehicle from a first speed to a second speed by means of the second electric machine, and increasing the speed n of the internal combustion engine from a first rotational speed to a second rotational speed. Increasing the speed of the internal combustion engine from the first rotational speed to the second rotational speed always takes place as a function of the increase in the speed of the motor vehicle from the first speed to the second speed. A motor vehicle may have such a serial-parallel hybrid powertrain.
