| |
| | | | |
| − | The communication in the Concept Car is implemented via a high-speed (1Mbit/s) CAN-Bus (Controller-area network), featuring a message based protocol. Each message has a message identifier to distinguish between different message types. CAN standard 2.0A is applied, so the message identifiers are 11 bits wide, allowing 2048 distinct messages. Further details about the CAN-Bus can be found in [[Bibliography|[ZS08]]].

| − | In the ConceptCar, only messages with the length of 4 Bytes, which are interpreted as an unsigned integer number, are used. How the message data has to be interpreted depends only on the message identifier, further details are given in Section [[ECUs Implementing Sensorboards and Actorboards|ECUs Implementing Sensorboards and Actorboards]], when the bus participant providing these messages is introduced.
