Method and Device for Secure Communication of a Component of a Vehicle with an External Communication Partner via a Wireless Communication Link

A method for secure communication of at least one of multiple components of a vehicle with at least one external communication partner via a wireless communication link, each of the multiple components including at least one communication module for data exchange, comprising:

• exchanging data packets between a transceiver device of the vehicle and an external transceiver station;
• ascertaining a communication status of the wireless communication link;
• and
• at least one of (a) enabling and (b) disabling as a function of the communication status at least one of (i) data exchange between at least one of (a) the at least one component and (b) the external communication partner and others of the multiple components and (ii) access of at least one of (a) the at least one component and (b) the external communication partner to the others of the multiple components.

A device for secure communication of at least one of multiple components of a vehicle with at least one external communication partner via a wireless communication link, each of the multiple components including at least one communication module configured for data exchange, comprising:

• a transceiver device of the vehicle configured to exchange data packets with an external transceiver station;
• an arrangement configured to ascertain a communication status of the wireless communication link;
• and
• an arrangement configured to at least one of (a) enable and (b) disable as a function of the communication status at least one of (a) data exchange between at least one of (i) the at least one component and (ii) the external communication partner and others of the multiple components and (b) access of at least one of (a) the at least one component and (b) the external communication partner to the others of the multiple components.

A communication system for secure communication of at least one of multiple components of a vehicle with at least one external communication partner via a wireless communication link, each of the multiple components including at least one communication module configured for data exchange, comprising:

• an external transceiver station including a WLAN access point;
• and
• a device including:
• a transceiver device of the vehicle configured to exchange data packets with the external transceiver station;
• an arrangement configured to ascertain a communication status of the wireless communication link;
• and
• an arrangement configured to at least one of (a) enable and (b) disable as a function of the communication status at least one of (a) data exchange between at least one of (i) the at least one component and (ii) the external communication partner and others of the multiple components and (b) access of at least one of (a) the at least one component and (b) the external communication partner to the others of the multiple components.
