Abstract:
1. A time-triggered communication system comprising: at least first and second channels and at least a first node and a second node that are communicatively coupled by the first and second channels; a first communication controller assigned to the first channel and a second communication controller assigned to the second channel, the first and the second communication controller each having a local clock, said two local clocks being physically separated; and an interface configured for inter-channel communication consisting of an information exchange regarding specific limiting points of respective time paths of the first and the second communication controllers, and arranged between the first communication controller and the second communication controller, wherein the second communication controller is configured to transmit a first limiting point to the first communication controller via the inter-channel interface at a start of a cycle on the second channel, the first communication controller is configured to transmit a second limiting point to the second communication controller via the inter-channel interface at a start of the cycle on the first channel, and the local clocks of the communication controllers are synchronized based on a temporal difference between the first and second limiting points.
