Abstract: Procedure for regenerating an exhaust gas after treatment system, especially a particle filter, of a combustion engine that is arranged in a motor vehicle, with regeneration cycles that are controlled by a control unit, whereby the control unit is provided with information data regarding the route and whereby the regeneration cycles are controlled with regard to the information data, is thereby characterized, in that the information data that regards the route contains driver specific information data.

Abstract: A method is described for operating an internal combustion engine in motor vehicles, in which air is supplied to a combustion chamber via a throttle valve and an air supply channel, and in which exhaust gas is conducted through a particulate filter and is returned at least intermittently and at least partially through an exhaust gas recirculation valve into the air supply channel, and in which an oxygen proportion in the exhaust gas is detected using at least one lambda probe. In this context, in an overrun operation, the throttle valve is controlled to close and the exhaust gas recirculation valve is controlled to open, a variable characterizing the oxygen concentration in the exhaust gas is compared to a boundary value, and as a function of the result of the comparison, it is concluded that there is a leakage in the air supply channel.

Abstract: A method and device for assisting in driving a vehicle, particularly a motor vehicle, having a surroundings detector for detecting at least a partial area of the surroundings of the vehicle, an output device for the output of information concerning the vehicle surroundings obtained from the surroundings detection to a driver, and an evaluation unit for determining a risk level based on the vehicle-surroundings information. To facilitate driving of the vehicle, it is provided that at least a portion of the vehicle-surroundings information provided for determining the risk level, and the risk level determined by the evaluation unit are output continuously by the output device to the driver during operation of the vehicle.
