The disclosure relates to a method for automatically carrying out safety measures when a vehicle drives on a shoulder differing from a roadway, comprising the following: detecting the shoulder which differs from the roadway and laterally adjoins the roadway by means of a detection apparatus of the vehicle, providing information regarding the position and/or type of the shoulder to the vehicle, recognizing that the vehicle is driving on the shoulder by means of an electronic evaluation unit, dangerous evaluating a situation which accompanies the driving of the vehicle on the shoulder and/or can accompany the same in the future, by means of the electronic evaluation unit, and carrying out a safety measure by tensioning at least one safety belt of a restraint system of the vehicle depending on the evaluated dangerous situation.

A method for operating a transportation vehicle having a vehicle system for performing a driving function in a normal mode, which, based on a first malfunction of the vehicle system, is operated in a first emergency mode for at least partial maintenance of the driving function. Also disclosed is a computer program product and a transportation vehicle.

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.

A safety system for vehicle lateral control for a Steer-by-Wire steering system of a motor vehicle with a main operating level for transmitting a steering wheel angle to at least one wheel of the motor vehicle, and with a Safety level for transmitting a steering wheel angle to at least one wheel of the motor vehicle. The safety level may be configured to become active if the main operating level fails. An emergency operating level is provided for vehicle lateral control, the emergency operating level being arranged to become active in the event of a failure of the main operating level and/or safety level.

The invention relates to a method for operating a motor vehicle that, due to an error in a main brake system of the motor vehicle, is switched by means of a control circuit from a normal mode to an error mode in which a performance of a drive unit of the motor vehicle is reduced, and at least one navigation function of the motor vehicle is activated. The invention provides that an additional function of the motor vehicle is activated in error mode by means of the control circuit. Moreover, the invention relates to a safety system that is designed to perform the above method, as well as to a motor vehicle equipped with such a safety system.

Method for operating a motor vehicle using an error brake safety system

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.

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.

Control device and method for adjusting the damper hardness of a vibration damper of a transportation vehicle

A method for estimating a friction coefficient of a roadway by a transportation vehicle, wherein a control device of the transportation vehicle receives a first estimated value of a maximum horizontal force from a traction control system that is transmitted to the roadway by a wheel of the transportation vehicle. A control device receives a second estimated value of a wheel contact-patch force of the wheel from a damper controller and calculates the friction coefficient as a vehicle-independent friction coefficient based on the estimated values from the wheel contact-patch force and the horizontal force.
