Abstract: The invention relates to a valve train (10) for an internal combustion engine, having a first rocker arm (32) which is mounted on a rocker shaft (30) so as to be pivotable around a pivot axis (44) in relation to the rocker shaft (30), having a first gas exchange valve (18) which can be actuated by pivoting the rocker arm (32) around the pivot axis (44) in relation to the rocker shaft (30) and can thus be moved translationally, and having a second gas exchange valve (20).
Abstract: A method for detecting lost image information via a lighting device and an optical sensor. The lighting device and the optical sensor are controlled so as to be chronologically aligned with each other. A visible spacing region in an observation region of the optical sensor is determined from the chronological alignment of the control of the lighting device and the optical sensor. A recording of the observation region with the optical sensor is generated via the aligned control. Image information is identified in the recording in regions outside of the spacing region visible in the image, so as to make the identified image information accessible.
Abstract: A ventilation system for a motor car includes an electronic display for displaying information and an air distribution chamber disposed on a back of the electronic display where air from the air distribution chamber is flowable through an air outlet and into an internal space of the motor car. An air calming chamber is disposed on a back of the air distribution chamber. The air calming chamber is at least partially separated fluidically from the air distribution chamber and is connected fluidically to the air distribution chamber via at least one through hole where via the at least one through hole the air distribution chamber is suppliable with air to be supplied to the internal space from the air calming chamber.

Abstract: A method for operating an internal combustion engine. The internal combustion engine has multiple cylinders and the cylinders are assigned a respective exhaust valve and intake valve. The internal combustion engine has a crankshaft, an intake camshaft, and an exhaust camshaft. Initially, the internal combustion engine is operated in a first operating state. A second operating state of the internal combustion engine is set by the intake camshaft being adjusted late relative to the crankshaft in comparison to the first operating state and the exhaust camshaft being adjusted early relative to the crankshaft in comparison to the first operating state. To set the second operating state, the intake camshaft is adjusted late by a first value which is in a range from 50-120 crank angle degrees and the exhaust camshaft is adjusted early by a second value which is in a range of 1-35 crank angle degrees.

Abstract: A method for communication between an at least partially autonomously driving motor vehicle and a pedestrian by a system includes detecting a presence of the pedestrian by detecting a presence of a mobile receiving device of the system on the pedestrian by the at least partially autonomously driving motor vehicle by a communication device of the at least partially autonomously driving motor vehicle. Depending on the detecting of the presence of the pedestrian, a first communication signal is transmitted from the at least partially autonomously driving motor vehicle to the mobile receiving device. A second communication signal is transmitted from the mobile receiving device to the communication device of the at least partially autonomously driving motor vehicle. The second communication signal is taken into account by the at least partially autonomously driving motor vehicle during an autonomous driving operation of the at least partially autonomously driving motor vehicle.

Abstract: A method for tracking an object. A first coordinated control of a lighting device and an optical sensor is assigned to a first visible distance range. A first recording of the first visible distance range while illuminated by the lighting device is recorded with the optical sensor. If the object is detected in the first recording within the first visible distance range, a distance between the detected object and the optical sensor is determined. A second coordinated control of the lighting device and the optical sensor and an assigned, second visible distance range are determined such that the object detected in the first recording is located in a center of the second visible distance range. A second recording of the second visible distance range while illuminated by the lighting device is recorded with the optical sensor by the second coordinated control.
Abstract: An injector sleeve for an injector for introducing a gaseous fuel into a combustion chamber of an internal combustion engine includes an intake in which the injector is at least partially receivable. A lateral surface on an external periphery has a longitudinal region around which a coolant flowing through a cooling chamber of the internal combustion engine is flowable. A sealing region connected to the longitudinal region seals the combustion chamber from the cooling chamber. A cap is arrangeable in the combustion chamber and the cap has a flow opening where gaseous fuel flowing out of the injector is directly flowable through the cap for shaping a jet of the gaseous fuel.
Abstract: A method for locking and releasing a securing device of a vehicle coupling of a vehicle includes switching the securing device between a locked state and a released state by a control command output by an authorization unit where the authorization unit outputs the control command after receiving an initiation command transmitted to the authorization unit by an interface and where a wireless communication interface and a local physical interface are useable as the interface. Sensor data, generated by a sensor that monitors surroundings of the vehicle, is transmitted via the wireless communication interface to a control center. The initiation command is transmitted to the vehicle by the control center via the wireless communication interface as a function of the sensor data. When there is no communication connection between the control center and the vehicle, it is only possible to output the initiation command via the local physical interface.

Abstract: A fluid filter for a motor vehicle includes a filter housing and a filter cartridge which is disposable in the filter housing. The filter housing has a housing pot and a covering element where the filter cartridge is connectable to the housing pot by rotating around a longitudinal axis of the filter cartridge. A holding element having a web is disposed on an end plate of the filter cartridge where the web protrudes from a wall of the holding element and where the wall is formed to be spiral shaped radially to the longitudinal axis. The web of the holding element is engageable behind a holding web in a mounting position of the filter cartridge where the holding web projects at a constant distance from a wall, formed to be spiral shaped radially to the longitudinal axis, of a counter bearing disposed on the housing pot.
Abstract: An electric drive system has a group transmission with a main group and a range group with a planetary gear set. First and second input shafts of the main group are respectively coupled with first and second electric engines. An output shaft of the main group is coupled with a first element of the planetary gear set and a second element of the planetary gear set is coupled with an output drive shaft of the group transmission. Two idler wheels are disposed coaxially to the first input shaft and two further idler wheels are disposed coaxially to the second input shaft. The first and second input shafts are coupled with the output shaft via two fixed gears. A first fixed gear engages with the first and third idler wheels and a second fixed gear engages with the second and fourth idler wheels.
