A method for generating secrets using a vehicle involves a computing unit reading input data and processing the input data to generate at least one secret using rules. At least action data is used as the input data, the action data being generated by the vehicle after carrying out at least one action. The computing unit calculates a unique pseudo-random byte sequence from the action data using the rules. The pseudo-random byte sequence is used as the secret or pseudo-random byte sequence is further processed by a function in order to derive the secret.

A method for anonymizing movement data of road users equipped with a position detection device involves collecting movement data in the form of individual time- and position-related data records and transmitting the collected movement data to a backend server. At least some data records are transmitted indirectly via at least one other vehicle, or the position or time reference in at least some data records is made noisy prior to the transmission.

Method for anonymizing movement data

A method for transmitting information between a data processing system external to the vehicle and systems using the information in a vehicle employs integrity protection and/or encryption mechanisms. The integrity and/or encryption mechanisms are used with different levels of protection, wherein the level of protection is selected and/or adjusted based on the information or a classification of the information, the provided use of the information, the state of the vehicle, the surroundings of the vehicle, the origin of the information, the protection goal, and/or the resource consumption.

A method for determining a set speed of an assistance system for controlling a longitudinal movement of a vehicle involves checking a route ahead of the vehicle with a predefined total route length to determine whether, on this total route length, there are areas with a free-flowing traffic state, areas with a slow-moving and/or congested traffic state, and areas with a gridlocked traffic state. A route length of each area is determined. Depending upon these determinations, it is decided whether the set speed is to be defined by the assistance system and to which of multiple predefined speed values the set speed is to be set.

A method for paying in a motor vehicle having a transaction device involves providing transaction data relating to the payment to the payment transmitter. The transaction data including a receiver address of a payment receiver, a payment amount, a transmitter address of a payment transmitter located in the motor vehicle, and a private key belonging to the transmitter address. The provided transaction data is entered into the transaction device. The entered receiver address is transmitted to the payment receiver, which authenticates the transmitted receiver address. Only if the authenticated receiver address is classified as authentic does the method proceed. This involves signaling the successful authentication of the receiver address to the payment transmitter and transmitting the entered transaction data entered to the cryptocurrency computer network for carrying out the payment. Accordingly, a transaction compiled from the transaction data is entered into at least one account book of the cryptocurrency computer network. A transaction status relating to the entry of the transaction is signaled to the payment transmitter.

A method for controlling an automated driving operation of a vehicle involves authorizing the automated driving operation according to a number of predetermined conditions. Traffic information and event information is received by the vehicle. The traffic information contains place- and time-referenced information about a traffic jam on a part of the route lying ahead of the vehicle and the event information contains place- and time-referenced information about an event on the part of the route lying ahead. The traffic information and the event information are evaluated by the vehicle as belonging together if these are close together in terms of place and time. The automated driving operation of the vehicle is not authorized if event information and traffic information is available for a predetermined prediction horizon, but only then if these are evaluated as not belonging together.

A method for operating an autonomously driving vehicle that is connected to a central computer unit via a communication connection for exchanging data. During the autonomous driving mode, a request to take over a driving task is emitted to a vehicle user when at least one takeover condition is fulfilled. The takeover condition is fulfilled when it is established that the communication connection to the central computer unit is disrupted on a route portion that exceeds a predetermined length and on which the vehicle is located or which the vehicle is approaching.
