Integrated fault diagnosis and prognosis for in-vehicle communications
First Claim
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.

Abstract
A method of diagnosing a fault in an in-vehicle communication system. The in-vehicle communication system includes a transmitting node, at least one receiving node, and a network communication bus coupling the transmitting node to the at least one receiving node. A message is transmitted from the transmitting node to the at least one receiving node over the communication bus. A fault detection technique is applied within the transmitting node for detecting a fault within the transmitting node. A fault detection technique is applied to the at least one receiving node for detecting a fault within the at least one receiving node. A fault detection technique is applied within the network communication bus for detecting a fault within the communication bus. An analyzer collectively analyzes results from each respective detection technique for isolating a fault within the in-vehicle communication system.
