Control unit architecture for vehicles

A method for transmitting a data packet from at least one second interface controller to a first interface controller, the method comprising:

• receiving the data packet by the at least one second interface controller;
• determining, by a data analyzer, a transmission strategy for the data packet, the transmission strategy comprising at least one of the following actions:
• i) using a maximum load for the data packet, wherein the maximum load for the data packet is a maximum number of packets per unit time for a data type,
• ii) rejecting data packets that exceed the maximum number of packets per unit time for the data type of the data packet,
• iii) sending the data packets that exceed the maximum number of packets per unit time for the data type of the data packet to at least one buffer store,
• iv) fragmenting the data packets that exceed the maximum number of packets per unit time for the data type of the data packet and sending the data packets that exceed the maximum number of packets per unit time for the data type of the data packet to the at least one buffer store, and
• v) sending the content of the at least one buffer store to the first interface controller based on the data type of the data packet;
• and
• implementing the transmission strategy for the data packet.

A control unit for transmitting a data packet from a first interface controller to at least one second interface controller and/or for transmitting a data packet from at least one second interface controller to a first interface controller, the control unit comprising:

• the first interface controller, a data analyzer, at least one buffer store, and at least one second interface controller, wherein the control unit is configured to:
• determine, by the data analyzer, a transmission strategy for the data packet, the transmission strategy comprising at least one of the following actions:
• i) using a maximum load for the data packet, wherein the maximum load for the data packet is a maximum number of packets per unit time for a data type,
• ii) rejecting data packets that exceed the maximum number of packets per unit time for the data type of the data packet,
• iii) sending the data packets that exceed the maximum number of packets per unit time for the data type of the data packet to at least one buffer store,
• iv) fragmenting the data packets that exceed the maximum number of packets per unit time for the data type of the data packet and sending the data packets that exceed the maximum number of packets per unit time for the data type of the data packet to the at least one buffer store, and
• v) sending the content of the at least one buffer store to the first interface controller based on the data type of the data packet;
• and
• implementing the transmission strategy for the data packet.
