Abstract: The present disclosure provides an apparatus and method for measuring echo responses of communication links used in in-vehicle networks with high resolution and high dynamic range, allowing for diagnostics of various failures and/or degradations with high precision. Additional information can be provided to indicate signaling quality, insertion loss, and return loss of the communication links used in in-vehicle networks. Together, these measures and information can provide a comprehensive diagnostic capability that improves network reliability and safety of in-vehicle networks.

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: 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 switch coupled between the one or more subsystems and the processing module re-routes traffic from the one or more subsystems to an external processing module upon failure of the local processing module.
