Abstract: A vehicle guidance system provides a driving function for automated longitudinal control of a vehicle. The vehicle guidance system is designed to detect, on the basis of environmental data, a first signaling unit which is arranged on a roadway on which the vehicle is traveling, ahead of the vehicle in the direction of travel. The vehicle guidance system is designed to determine driver data relating to the attentiveness of the driver of the vehicle when monitoring the driving function and to operate the driving function relating to the automated longitudinal control of the vehicle according to the driver data at the first signaling unit.

Abstract: A vehicle control system provides a driving function for automated longitudinal control of a vehicle at a signaling unit, the driving function having an automated mode and a manual mode. The vehicle control system is designed to consecutively detect a plurality of signaling units during travel of the vehicle. The vehicle control system is also designed to determine, for each of the plurality of signaling units and on the basis of data relating to the relevant signaling unit, whether the driving function can be operated in the automated mode or only in the manual mode at the relevant signaling unit. The vehicle control system is further designed to operate the driving function in the manual mode at at least one first signaling unit of the plurality of signaling units although it has been determined, on the basis of the data relating to the first signaling unit, that the first signaling unit can be operated in the automated mode.

Abstract: A vehicle guidance system provides a driving function for automated longitudinal control of a vehicle. The vehicle guidance system is designed to detect, on the basis of environmental data, a first signaling unit which is located on the roadway on which the vehicle is traveling, in front of the vehicle in the direction of travel. The vehicle guidance system is furthermore designed to determine that a contradiction exists between the first signaling unit, detected on the basis of the environmental data, and map data in respect to a roadway network in which the vehicle is traveling. In addition, the vehicle guidance system is designed to effect a non-availability output in response thereto in order to inform a user of the vehicle that the first signaling unit detected on the basis of the environmental data is not taken into consideration in the driving function for automated longitudinal control of the vehicle.

Abstract: Described is a vehicle control system for providing a driving function for the automated longitudinal control of a vehicle at a signaling unit. The vehicle control system is configured to detect, during operation of the driving function, a first signaling unit located ahead of the vehicle in the direction of travel on a roadway on which the vehicle travels. The vehicle control system is additionally configured to ascertain one set driving mode of a plurality of different driving modes and to cause the vehicle to be automatedly longitudinally controlled according to the set driving mode when the vehicle approaches the first signaling unit.

Abstract: A vehicle control system provides a driving function for automated longitudinal control of a vehicle. The vehicle control system is designed to detect that the accelerator pedal of the vehicle is actuated. The vehicle control system is also designed to capture actuation information in relation to the actuation of the accelerator pedal and/or in relation to a response of the vehicle caused by the actuation of the accelerator pedal, and to adapt the operation of the driving function according to the actuation information.

Abstract: A device for identifying a signaling unit on a road on which a vehicle is traveling is described. The device is configured to determine an arrangement of one or more signal signs of the signaling unit on the basis of environmental data of one or more environmental sensors of the vehicle. The device is further configured to assign the one or more signal signs to one or more corresponding grid cells of a signal sign grid based on assignment logic.

Abstract: A clamp assembly has a clamp with a clamp band and a clamping device for clamping the clamping band and has a heat protection device with a housing and at least one insulating layer. The housing has a respective wall at each axial end face, the wall being divided into sections and protruding radially inwards, and the at least one insulating layer can be positioned between the walls of the housing. The clamp can be surrounded at least in some regions by the housing and/or the at least one insulating layer of the heat protection device, and the heat protection device is designed to be connectable to the clamp.

Abstract: A profiled clamp having a clamp band and a clamping device which has two clamping jaws arranged at a distance (D) from one another in the circumferential direction (U). The clamping jaws are arranged on each end of the clamp band and can be moved towards one another by means of at least one clamping means. On an inner side of the clamp band, at least two profiled segments are arranged circumferentially spaced apart from one another. The profiled segments can be connected to the clamp band in each case by means of at least one latching connection.

Abstract: A clawed securing means, in particular a pipe coupling, having a band with two halves, which each have a clamping jaw at the ends thereof, the opposing clamping jaws of the two halves being connected to each other in each case by at least one clamping element. The clamping jaws each have at least one lug with a fixed end and a free end. The free end is bent in such a manner that the free end rests on the fixed end of the respective lug and forms a double layer of material. At least one opening is formed in the region of the double layer of material to feed through the at least one clamping element.
