Assignee:

Visteon Global Technologies, Inc. - Dearborn MI

International Classification:

G06F007/00

US Classification:

701 36, 701 33, 340438, 340439

Abstract:

A “segmented” CAN bus is provided that extends the cabling scheme of a CAN network to permit isolation of individual nodes of identical type when needed and the ability for a host to determine the network topology. In addition, the CAN bus cabling scheme automatically assigns unique addresses to nodes and guarantees that the network will always be properly terminated. This eliminates the need for jumpers, DIP switches, pre-installation programming, or other hardware requiring human intervention to uniquely identify the nodes on the network. Furthermore, because the physical node topology is determinable, equipment installation and anomaly diagnostics are facilitated.

Abstract:

An audio signal processing system for a vehicle is disclosed. The vehicle has a plurality of audio output producing devices. The system includes an audio input circuit, a processor, an audio output circuit, and at lease one speaker. The audio input circuit receives a plurality of audio signals from the plurality audio output producing devices. The processor is in communication with the audio input circuit for combining the plurality of audio signals. The audio output circuit is in communication with the audio input circuit for receiving the combined plurality of audio output signals. The audio output circuit conditions the plurality of audio signals for output. The at least one speaker broadcasts the conditioned plurality of audio signals to a vehicle occupant.
