CONTROL METHOD FOR AUTOMATICALLY ESTABLISHING OR AUTOMATICALLY SWITCHING VEHICLE COMMUNICATION FOR DATA EXCHANGE BETWEEN A VEHICLE AND A REMOTE STATION
A method for automatically establishing or automatically switching vehicle communication for data exchange between a vehicle and a remote station involves the vehicle being driven with various levels of autonomy. The data is transmitted between the vehicle and the remote station via at least one of the following types of network connection: a network connection in a terrestrial network, a network connection in a non-terrestrial network; and parallel network connections in a terrestrial and a non-terrestrial network. The type of network connection is selected based on a currently set and/or requested level of autonomy.
A method for operating a vehicle in an automated driving operation involves a main control device determining a driving instruction and providing it to an auxiliary control device. The driving instruction includes information about a course of a path on which the vehicle should be guided into a stopping position, which is determined by a series of path points having a spacing value assigned to each path point. The spacing value corresponds to a spacing of the path point from left or right lane markings. Spacing values are transmitted to the auxiliary control device as digital data having a limited representable value range of the spacing values. The spacing values are reduced by scaling before the transmission to the auxiliary control device, and are calculated back in the auxiliary control device after the transmission if a lane width is greater than the representable value range of the spacing values.

The first and second cut-outs extend only partially along a width of the base body resulting in a first material bridge from the first cut-out to the second side and a second material bridge from the second cut-out to the first side. The first cut-out is spaced from the second cut-out.
User comfort of a vehicle occupant staying in a vehicle is increased by conveying haptic feedback to the vehicle occupant using an actuator arranged in the vehicle.

The first mobile terminal communicates directly or indirectly via a second mobile terminal with the computer unit of the vehicle. Control signals emitted by the program run on the first mobile terminal are conveyed to the computer unit. The computer unit of the vehicle controls the at least one actuator arranged in the vehicle for generating the haptic feedback depending on the control signals received by the first mobile terminal.
