Abstract: Technologies and techniques for ascertaining a vehicle trajectory, via a system that includes a motor vehicle and a network server. Individual trajectories of a plurality of motor vehicles being traversed, and secondary information linked to the individual trajectories are detected. The individual trajectories of the plurality of motor vehicles, and the linked secondary information may be transmitted to a network server. A swarm trajectory may be ascertained by a network server as an average of the individual trajectories using the individual trajectories and the linked secondary information, wherein the average may be weighted using the secondary information. The network server may transmit the swarm trajectory to at least one motor vehicle. An associated motor vehicle configured for the system and network server is further disclosed.

Abstract: Technologies and techniques for operating an assistance system in a motor vehicle with which a driving a shoulder by the motor vehicle is detected by means of at least one detection device in the assistance system, and with which a control signal is generated by means of an electronic computing device in the assistance system for engaging with a functional unit in the motor vehicle. The shoulder that is detected is evaluated in terms of the type of shoulder, and a critical or non-critical driving of the vehicle on the shoulder is determined on the basis of the type of shoulder, and the control signal is generated in the case of a critical driving on the shoulder. The present disclosure also relates to an assistance system.

Abstract: A method for adjusting the damper hardness of a vibration damper of a wheel of a transportation vehicle, wherein the transportation vehicle body movement signal is generated by a control device of the transportation vehicle from a first sensor signal of the first sensor unit connected fixedly in to a transportation vehicle body, a wheel movement signal is generated from a second sensor signal of a second sensor unit which detects a wheel position of the wheel with respect to the body, a speed signal which describes a speed of the transportation vehicle body is generated based on the transportation vehicle body movement signal, and the wheel movement signal and an actuation signal for setting the damper hardness is generated based on the speed signal. The transportation vehicle body movement signal is filtered by a first filter unit and/or the wheel movement signal is filtered by a second filter unit.
