Abstract: A method for monitoring a controller for a vehicle includes determining configuration information associated with the vehicle and determining vehicle operating states associated with a plurality of conditions. A statistical analysis is executed to correlate a plurality of faults with the vehicle operating states and the configuration information associated with the vehicle. The plurality of faults in the controller can be isolated to one of a hardware fault or a software fault based upon the statistical analysis and the configuration information associated with the vehicle.

Abstract: A system and method for reconfigurable inter-processor communications in a controller. The system and method include providing multiple processors in the controller and generating a send buffer and a receive buffer for each of the processors. The system and method further include generating a send table and a receive table for each of the processors where the send table stores identifying information about messages being sent and where the receive table stores identifying information about messages being received, and providing infrastructure services that include protocols for sending and receiving messages between multiple processors in the controller.
