A method for operating a bus system, in which a message of the bus system is received and its validity is ascertained, wherein, if it was ascertained that the message is 'malicious', a new message is sent to the designated receiver of this 'non-malicious' message, the content of the new message having been previously rated as &#x201c;non-malicious.&#x201d;

Method and device for operating a bus system

A method for creating rules for recognizing anomalies in a data stream of data packets. The method includes: providing a reference time signal having successive reference points in time; for at least two data portions from one or multiple data packets determined by a selected data packet type in a data stream section, ascertaining a time series of successive values of the relevant data portion, the values of the time series corresponding to the values of the relevant data portion or being a function of these values, the values of the relevant data portion each being assigned to a respective reference point in time of the respective reference points in time; carrying out a correlation method in order to ascertain, in each case, one correlation value for at least two different time series; creating a rule for the rule-based anomaly recognition method as a function of the ascertained correlation values.

Method for the automated creation of rules for a rule-based anomaly recognition in a data stream

A method for evaluating signal data includes a bus signal channel supplying the signal data, a reference channel supplying reference signal values, which form the basis of the signal data, and a computer performing a signal interpretation based on an interpretable portion of the signal data and on the reference signal values, and reconstructing a signal based on the interpretation.

Method and device for evaluating signal data

A method for operating a bus system in which a message of the bus system is received and its validity is ascertained, characterized in that, when it has been ascertained that the message is 'not valid', a defend message is transmitted to a designated recipient of the message, the defend message being configured so that the designated recipient is instructed by way of the defend message to initiate defensive measures against the message.

A method for operating a battery system in a vehicle that includes multiple battery units is described. The method includes classifying an instantaneous aging state of the battery units, first association of the battery units with instantaneous aging classes as a function of their instantaneous aging state, predicting a future aging state of the battery units for a future point in time, second association of the battery units with future aging classes as a function of their future aging state, ascertaining an optimal point in time for replacing battery units based on a cost function, taking into account the instantaneous aging classes and the future aging classes. A battery management system that is configured for carrying out the method is also described.

Method for operating a battery system, and battery management system

A method is provided for operating a bus system in particular of a motor vehicle, in which messages of the bus system are received, and as a function of these messages, it is detected whether a party of the bus system sending these messages is a party logging on to the bus system.
