Abstract: A vehicle control system for operating a driving function for the automated longitudinal and/or lateral control of a motor vehicle at a traffic node. The system includes sensors that provide situational data, and a control unit. The control unit identifies a lane in which the vehicle is located, in an approach road to the node, based on the situational data. The control unit determines whether at least one signal generator of a signaling unit of the node is relevant to a driving maneuver of the vehicle at the node, based on the identified lane. The control unit operates the driving function at the node based on whether at least one signal generator is relevant to the driving maneuver of the vehicle at the node.

Abstract: A device for controlling a driving function for the automated longitudinal guidance and/or lateral guidance of a vehicle is configured to determine driving situation data for different driving situations during the operation of the driving function in at least one vehicle, in which driving situations the automated longitudinal guidance and/or lateral guidance of the vehicle effected by the driving function was limited. The device is also configured to identify, based on the driving situation data for the different driving situations, a first type of driving situations for which and/or a first location at which the automated longitudinal guidance and/or lateral guidance of the vehicle effected by the driving function was frequently limited. Furthermore, the device is configured to cause the driving function not to be operated or to be operated only with a reduced degree of automation in a driving situation of the first type and/or at the first location.

Abstract: The invention relates to systems, methods and devices that detect a bypass lane at a junction with at least one traffic light system and control automated longitudinal guidance functions of a motor vehicle based thereon. The driving data of a motor vehicle at the junction is utilized to determine a possible driving trajectory of vehicles at the junction and arrangement information reflecting an arrangement of the traffic light system relative to the possible driving trajectory. The bypass lane of the junction is detected based on the arrangement information, the automated longitudinal guidance functions of the motor vehicle are adjusted based on the bypass lane detection.

Abstract: A device for determining map data with respect to a route portion, configured to acquire a first set of first observations during a first trip along the route portion and a second set of second observations during a second trip along the route portion, determine values of a measure of similarity for different possible observation pairs each consisting of one first observation and one second observation, determine, on the basis of the values of the measure of similarity for different possible observation pairs, an overall association with one or more one-to-one associations between, in each case, one first observation from the first set and one second observation from the second set. The device is also configured to determine the map data with respect to the route portion on the basis of the overall association.

Abstract: A vehicle control system provides a driving function for automated longitudinal control of a vehicle. The vehicle control system is designed to determine, on the basis of surroundings data from one or more surroundings sensors of the vehicle, positional data relating to the position of a first signaling unit, which is located in front of the vehicle in the direction of travel, in relation to the position of the vehicle. The vehicle control system is also designed to determine, on the basis of map data relating to a road network traveled on by the vehicle, distance data relating to the distance between the first signaling unit and a stop line of the first signaling unit. The vehicle control system is further designed to cause automated deceleration of the vehicle at the first signaling unit on the basis of the positional data and the distance data.

Abstract: A device for detecting a signal generator that is not relevant for motor vehicles determines environment data from one or more environment sensors of at least one motor vehicle during at least one journey at a junction, determines, on the basis of the environment data, information about the position and/or orientation of a plurality of signal generators at the junction with respect to one another and/or with respect to a stop line at the junction. Furthermore, the device identifies at least one non-relevant signal generator from the plurality of signal generators on the basis of the information about the position and/or orientation.

Abstract: Process and apparatus for pre-treatment of a substrate surface in a vacuum by a glow discharge for a subsequent coating process in a vacuum. The process includes maintaining a low pressure glow discharge between the substrate to be pre-treated and a counter-electrode, where the counter-electrode composed of at least a component of the coating to be deposited in the vacuum coating process. The process also includes periodically alternating a polarity of the substrate to act as a cathode or as an anode of the low pressure glow discharge, and individually controlling at least one of pulse length and discharge voltage in both polarities. A frequency of alternation of the polarity is set within a range of between 1 Hz and 1000 kHz. The apparatus includes an evacuatable vacuum chamber, a substrate holder positioned to hold a substrate to be pre-treated, at least one counter-electrode, and an alternating voltage generator coupled to the substrate to be pre-treated and the at least one counter-electrode.

Abstract: A method for the electron beam deposition of a multicomponent evaporant to ensure a consistent layer quality with constant composition and thickness in a defined manner. The X-radiation emitted from the evaporant on the point of electron beam impingement is measured in situ, using the obtained signal as reference input to control the parameters of the evaporation process and therefore to control the deposition rate and material composition of the deposited layer. The method is used for the production of corrosion resistant, high-temperature resistant, hard-wearing or optical layers on, for example, strip steel or plastic film.

Abstract: Compound body of a vacuum coated sintered material and a process for its production. Such compound bodies, when coated in a known manner, have a carrier of sintered material coated with a layer that is thermally, mechanically and chemically unstable, with their surface showings cracks and being partially porous. These shortcomings are overcome via an improved eco-friendly vacuum deposition process, wherein at least one layer of a material, having an outer layer of Al.sub.2 O.sub.3, is applied to the carrier of sintered material at a maximum of 800.degree. C., with this layer being completely crystalline and comprised of an .alpha.Al.sub.2 O.sub..sub.3 phase and possibly of a .gamma.Al.sub.2 O.sub.3 phase with a (440) texture, having a compressive stress of at least 1 GPa and a hardness of at least 20 GPa, with the Al.sub.2 O.sub.

Abstract: Silver-tin alloys can be deposited by the galvanic method from a cyanide-free bath which is prepared using silver as the nitrate or diammine complex, tin as the soluble tin(II) or tin(IV) compound and mercaptoalkane-carboxylic acids and -sulfonic acids, Uniform and adhering coatings of silver-tin alloys with a silver content of approximately 20 to 99 weight % can be deposited from said bath. Silver-tin alloys are electrodeposited from said bath at a pH of 0 to 14 and a current density of 0.1 to 10 A/dm.sup.2.
