Abstract: A threat is detected for a processing system of a motor vehicle. In a first step, driving context data associated with a driving context of the motor vehicle are received. In addition, driving pattern data may be received. Simulated network messages of the motor vehicle are then generated from the driving context data and, if available, the driving pattern data. Finally, by comparing the simulated network messages with actual network messages of the motor vehicle, a threat is detected. In addition, a threat may be predicted from the simulated network messages. In case a threat is detected or predicted, appropriate counter measures may be initiated.

Abstract: Voice communication, between a speaker and a recipient, either or both of which may be in a motor vehicle, is provided via a communication network. In a first step, an input speech utterance is received from the speaker. Optionally, a bandwidth of a connection to the communication network is evaluated at the side of the speaker. The input speech utterance is then converted to text. At least the text is transmitted over the communication network. In case of a sufficiently large bandwidth, the input speech utterance may be transmitted as voice and as text. The transmitted text is converted into an output speech utterance that simulates a voice of the speaker. Finally, the output speech utterance is provided to the recipient.
