    Abstract: Automotive area networks (AAN) have a substantially fixed network topology, meaning that the physical media used for communications between devices included in the AAN is known. For example, the physical connections within an AAN, sometimes provided by wiring harnesses, can include fixed lengths of twisted pairs of wire (“twisted pairs”). Pre-compensation parameters related to characteristics of the twisted pairs can be determined at the factory, and loaded into the memory of devices connected to the AAN. These pre-compensation parameters are used to improve the fast wake up and link acquisition times of connected devices. Various characteristics of the physical communication channel are measured or estimated as a function of mechanical, ingress, climactic, and environmental variations (MICE), and used to update the pre-compensation parameters.

    Abstract: Transceiver self-diagnostics for electromagnetic interference (EMI) degradation in balanced channels. Selective operation of transmitting a common mode signal from a communication link implemented for supporting differential signaling, and appropriate processing of any detected signal energy, such as that corresponding to differential signal energy, provides a measure of electromagnetic compatibility (EMC) corresponding to the communication link. Comparison of detected differential signal energy to one or more thresholds may provide indication of whether or not the communication link is balanced or unbalanced, a degree or margin with which the communication link is compliant in accordance with EMC in accordance with one or more protocols, standards, or recommended practices. Multiple successive measurements of detected differential signal energy may be used to determine a trend of performance, such as whether or not the communication link is trending toward imbalance, failure, or noncompliance.

    Abstract: Network node modules within a vehicle are arranged to form a reconfigurable automotive neural network. Each network node module includes one or more subsystems for performing one or more operations and a local processing module for communicating with the one or more subsystems. A management system enables traffic from the one or more subsystems of a particular network node module to be re-routed to an external processing module upon failure of the local processing module of that particular network node module.
