Abstract

In a method for processing messages with the aid of at least one Ethernet controller having a message store, the at least one Ethernet controller checks a received message for the presence of at least one property, and the received message is stored in the message store if this at least one property applies to the message.

Claims

1. A method for processing electronic messages for a motor vehicle, the method comprising:

checking, using at least one Ethernet controller having a message storage, a first received message to determine whether the first received message includes at least one predefined property;

storing the first received message in the message storage responsive to the determination being that the first received message includes the at least one predefined property, wherein the first received message includes a value of at least one operating parameter of the motor vehicle, and the at least one property is defined by the at least one operating parameter;

checking, using the at least one Ethernet controller having the message storage, a second received message to determine whether the second received message includes the same at least one predefined property; and

overwriting the first received message in the message storage with the second received message responsive to the determination being that the second received message includes the same at least one predefined property.

2. The method as recited in claim 1, wherein the first and second received messages are sent from at least one communication controller.

3. The method as recited in claim 2, wherein the first and second received messages are sent within a network using an Internet protocol.

4. A system for processing messages, the system being situated in a motor vehicle and comprising:

an Ethernet controller which has a message storage, wherein;

the at least one Ethernet controller is configured to;

(i) check at least one first received message to determine whether the first received message includes at least one predefined property;

(ii) store the first received message in the message storage responsive to the determination being that the first received message has the at least one predefined property;

(iii) check at least one second received message to determine whether the second received message includes the same at least one predefined property; and

(iv) overwrite the first received message in the message storage with the second received message responsive to the determination being that the second received message has the same at least one predefined property;

the first received message includes a value of at least one operating parameter of the motor vehicle; and

the at least one predefined property is defined by the at least one operating parameter.

5. The system as recited in claim 4, wherein the message storage has multiple memory spaces, and wherein one memory space is reserved for a message which has the at least one property.

6. The system as recited in claim 5, further comprising:

a communication controller which has a send register, wherein the communication controller is configured to send a message to the Ethernet controller after a write operation is carried out by the send register.

7. The system as recited in claim 5, wherein the system is configured to exchange messages from a network situated in the motor vehicle.
