Abstract: A method for driving autonomously out of a parked position by a vehicle is provided. It comprises the steps of: a) detecting an unlock-signal for unlocking a central locking system of a first vehicle parked at a first position by a second vehicle parked at a second position; b) determining whether the two vehicles are parked parallelly and directly next to each other; c) if so, driving the second vehicle autonomously at least partly out of the second position; d) determining whether the first vehicle has left at least partly said first position; and, e) if so, driving the second vehicle autonomously back in said second position.

Abstract: A communication method between road users, which can each connect to a server via at least one communication interface. The following steps carried out by the server for establishing communication: establishing local and thematic information for determining communication participants; determining a group of communication participants based on local and thematic information, with a local area being defined for the local restriction of the communication participants and with at least one technological aspect and/or one interest-based aspect being taken as a basis for the thematic restriction on the part of the server; and granting permission for data communication by the road users based on the server prioritizing the data transmitted by the road users to the server once the group has been determined. The local and thematic information determined from the average of the spatial coordinates of the road users and respective average speed and average direction of the road users.

Abstract: The correctness of information transmitted by a vehicle is assessed. Vehicle information about vehicle characteristics of a vehicle is received, wherein a vehicle trust value is assigned to the vehicle. Detector information about the vehicle characteristics is received, which is based on a detection of the vehicle characteristics by at least one detector outside the vehicle, wherein a detector trust value is assigned to the detector. Then, the correctness of the vehicle information is assessed. A correctness value is assigned to the vehicle information, and the vehicle trust value is updated. The vehicle information may be discarded when the correctness value is too low. Vehicles with a high trust value may validate other vehicles, which may in turn validate even more vehicles. In this way, a chain of vehicles with a high trust value (or trusted vehicles) may be established.

Abstract: A method for controlling the operation of an automatic driving assistance system of a motor vehicle, which is designed for independent vehicle guidance. When at least one driving control takeover condition is met which brings about deactivation of the driving assistance system when driving control is taken over by the driver, at least one takeover request is output to the driver. If the driver does not react to this takeover request, replanning of the original route occurs with an original destination to a stopping point which can be approached in an automated manner. The replanning occurs in such a way that the stopping point constitutes, in the context of the present position of the motor vehicle with respect to the original destination, an optimum stopping point which is determined according to at least one optimality criterion.

Abstract: A method for assisting in the parking of a vehicle in a vacant parking area, wherein the position of at least one vacant parking area is calculated on the basis of a vehicle-to-vehicle and/or a vehicle-to-infrastructure communication from the current position of the vehicle and is conveyed to a navigation apparatus of the vehicle, wherein a parking process is started by virtue of a radio key of the vehicle being placed onto a smartphone display, so that a lens in the vehicle key captures a flashing code and the radio key returns the flashing codes to the vehicle by radio.

Abstract: The invention relates to the transmission of multimedia data, which is to be output, from a computer device to a vehicle multimedia device. The vehicle multimedia device has a control device which is designed to determine a piece of vehicle status information in order to transmit said information to the computer device. On the basis of the vehicle status information, the computer device generates release data which determines to what extent the multimedia data is to be output. The computer device transmits the multimedia data and the release data to the vehicle multimedia device, which multimedia device outputs, by means of an output device, the maximum multimedia data to the extent defined by the release data.

Abstract: A mobile radio receiver for a vehicle includes a tuner front-end section, an inter-vehicle communication port, and a data processing unit. The data processing unit is operably connected with the tuner front-end section and with the inter-vehicle communication port. The data processing unit has at least two pre-determined relationship data sets. In use, the inter-vehicle communication port receives a tuner front-end section parameter data pointer. The pre-determined relationship data sets are used to determine a set of tuner front-end section parameters based on the tuner front-end section parameter data pointer. The mobile radio receiver provides an operational mode, a parameter reception mode, a tuner parameter adjustment mode, and a tuner parameter application mode.
