Abstract:
1. A method of diagnosing a fault in an in-vehicle communication system, the in-vehicle communication system including a transmitting node, at least one receiving node, and a network communication bus coupling the transmitting node to the at least one receiving node, each of the transmitting node and the at least one receiving node including a plurality of communication layers for servicing messages within each of the nodes within the in-vehicle communication system, the plurality of communication layers of each node including at least an application layer, an interaction layer, a data link layer, and a physical layer, the method comprising the steps of: transmitting a message from the transmitting node to the at least one receiving node over the communication bus; applying a fault detection technique within the transmitting node for detecting a fault within the transmitting node; applying a fault detection technique within the at least one receiving node for detecting a fault within the at least one receiving node; applying a fault detection technique within the network communication bus for detecting a fault within the communication bus; and an analyzer collectively analyzing results from each respective detection technique for isolating a fault within the in-vehicle communication system.
