Abstract:
1. A method for implementing cross-network synchronization of nodes on a vehicle bus, said method comprising: periodically sampling a notion of time from a first network wherein the first network includes a plurality of communication links, each link having at least one node; transmitting a message that includes the notion of time from the first network to a second network, wherein the second network includes a plurality of communication links, each link having at least one node; updating a local clock on the at least one node on the second network node based on the notion of time in the message; wherein the first network is a FlexRay network and includes at least one gateway electronic control unit having at least one microprocessor configured to create a system-wide synchronized time message; wherein the second network is a CAN network; and wherein the notion of time includes a timing offset to compensate for a delay associated with transmitting the message to the second network.
