Abstract: A method for operating a drive device which has an exhaust gas-generating drive unit and at least one vehicle SCR catalytic converter for aftertreatment of the exhaust gas. A reducing agent is added to the exhaust gas at least temporarily upstream of the vehicle catalytic converter. A first nitrogen oxide value describing the nitrogen oxide content of the exhaust gas upstream of the vehicle catalytic converter and a second nitrogen oxide value describing the nitrogen oxide content of the exhaust gas downstream of the vehicle catalytic converter are determined and, at least temporarily, a first slip indicator is determined using a first reducing agent slip model and a second slip indicator is determined using a second reducing agent slip model on the basis of the nitrogen oxide values. A total slip indicator is determined from the first slip indicator and the second slip indicator.

Abstract: A method for operating a multiple clutch transmission for a motor vehicle. The multiple clutch transmission includes a transmission input shaft coupled or couplable to a drive device of the motor vehicle and a transmission output shaft, which are drive-coupled to one another at least temporarily via a first clutch and a first sub-transmission and at least temporarily via a second clutch and a second sub-transmission. An electric machine is coupled to the output side of the multiple clutch transmission at least temporarily to provide a drive torque. A first target clutch torque other than zero is set at least temporarily on the first clutch and a second target clutch torque other than zero is set at the same time on the second clutch.

Abstract: A device for detecting the surroundings of a vehicle and a method for detecting the surroundings, and a vehicle designed to carry out said method comprise a camera module, a camera control apparatus, an analysis unit and an illumination device. The illumination device is formed by a matrix headlight of the vehicle and is designed such that it can project a light pattern into the surroundings. The projected light pattern is imaged in the detection region of the camera module and the 3D position of measurement points formed by the light pattern in the surroundings is determined by the analysis unit. However, the illumination device projects the light pattern only into regions of the surroundings in which the analysis unit has ascertained, based on image data, a value that is critical for 3D position determination.
