The disclosure relates to a method for operating a driver assistance system of a vehicle. The driver assistance system is designed to effect lateral guidance of the vehicle. For lateral guidance, the driver assistance system uses data which are provided to the driver assistance system by a vehicle-external memory apparatus. Support points are selected from the map data, which are changed by means of a computing apparatus of the vehicle into a data format usable for lateral guidance, and are then used by the driver assistance system for lateral guidance. The support points to be changed into the data format and can be used for lateral guidance are selected depending on a driving situation of the vehicle. Furthermore, the disclosure relates to a corresponding vehicle.

A method for operating a transportation vehicle wherein an image capturing unit is used to generate an optical image of an upcoming roadway lying ahead in the direction of travel of the transportation vehicle. The image is used to ascertain an ego lane of the roadway assigned to the transportation vehicle and an upcoming profile of the ego lane. At least one item of meta information that influences the detection of the ego lane and/or of the upcoming profile of the ego lane is captured. Swarm data pertaining to the roadway are retrieved from a database, a comparison lane of the roadway and a comparison profile of the comparison lane are derived from the swarm data, and the at least one item of meta information, the upcoming profile and the comparison profile are used to ascertain an uncertainty factor for the image from the image capturing unit.

Technologies and techniques for operating a driver-assistance system of a vehicle, in which the driver-assistance system at least indirectly takes into account a travelling speed of at least one other vehicle, at which the at least one other vehicle has driven around a bend ahead of the vehicle in the travelling direction of the vehicle. A travelling speed of the vehicle provided by the driver-assistance system for driving around the bend is checked, with the travelling speed of the at least one other vehicle being at least indirectly taking into account for this check. Other aspects relate to a method directed to a driver-assistance system.

A method for creating a guidance trajectory for a first transportation vehicle which includes receiving swarm data for a route section that represent at least one motion trajectory of at least one second transportation vehicle traveling through this route section; determining a distance from the at least one motion trajectory represented by the swarm data to a determined roadway edge for the route section; and using an electronic computing device to apply the at least one motion trajectory to ascertain the guidance trajectory for the first transportation vehicle in response to the distance associated with the respective motion trajectory being greater than or equal to a predefined limit value for the route section, and to provide the guidance trajectory for the first transportation vehicle, as a result of which the first transportation vehicle is transversely controlled using the guidance trajectory.

Technologies and techniques for carrying out an assisted lane change onto a deceleration lane, during which an intervention in an acceleration device may be carried out in an at least partially assisted manner as a function of a driver input on a driving lane of the roadway. The lane change from the driving lane onto the deceleration lane may be carried out in an at least partially assisted manner, wherein swarm data are received from at least one further motor vehicle, which carried out a lane change onto the deceleration lane at a crossing, and a change position for the lane change of the motor vehicle is determined as a function of the received crossing position. The lane change is carried out at the determined change position. Other aspects relate to a computer program product and to an assistance system.

Technologies and techniques for laterally controlling a motor vehicle on a road, where a roadway marking assigned to a driver's side of the motor vehicle is assigned to a lane type based on sensor data. The lane type characterizes whether the roadway marking is assigned to an ego lane on which the motor vehicle is to be guided, or whether it is assigned to a neighboring lane adjacent to the ego lane. The roadway marking is also assigned to the lane type, based on swarm data, and the lane type assigned to the roadway marking is established as the lane type that is determined as a function of the swarm data when the sensor lane type and the swarm data lane type diverge. The motor vehicle is laterally controlled as a function of the established lane type of the roadway marking assigned to the driver's side of the motor vehicle.

The disclosure relates a method for generating a change of travel lane recommendation for a motor vehicle from a starting travel lane into a target travel lane, wherein the motor vehicle moves along the starting travel lane at an own speed. A current position of the motor vehicle along the starting travel lane is determined in a digital environment map. A known starting travel lane speed is stored in the digital environment map for the current position along the starting travel lane. A lane change assistant compares the own speed of the motor vehicle with the starting travel lane speed and generates the change of travel lane recommendation as soon as a deviation between the own speed and the starting travel lane speed reaches a predefined threshold.

A lane-keeping assistance system of a motor vehicle, which is at least partially operated with assistance, in which an environment of the motor vehicle with a potential lane is detected via an optical detection device of the lane-keeping assistance system and evaluated via an electronic computing device of the lane-keeping assistance system and in which, as a function of the evaluated environment, an at least partially assisted lane-keeping movement is carried out by means of a transverse control device of the lane-keeping assistance system, wherein swarm data provided by an electronic computing device, which is external relative to the vehicle, are taken into account for evaluating the environment, wherein a future drivable route, which is outside of a detection area of the optical detection device, is evaluated on the basis of the swarm data, and a future partially assisted lane-keeping movement for the transverse control device is determined.

Technologies and techniques for the lateral control of a vehicle. Environment data of a vehicle is detected when travelling a route, and stored environment data, detected when travelling the route by a plurality of other vehicles not currently travelling the route, is received. The plausibility of the stored environment data is checked on the basis of the environment data detected. Lateral control of the vehicle is executed on the basis of the environment data checked for plausibility.

In a method for reducing risks in road traffic, using a motor vehicle an information signal is generated and transmitted to an analysis unit. The information signal contains a position of the corresponding motor vehicle and an associated hazard level. Using the analysis unit, the position is assigned to a route section and a risk characteristic value is determined as a function of the hazard level. Using the analysis unit, a risk signal is generated based on the risk characteristic value and provided to at least one traffic participant.
