Abstract
Disclosed are controller area network (CAN) nodes and associated methods for communicating through a CAN bus to form a set of communicatively coupled CAN nodes. A CAN node has, and is configured to monitor status of, one or both input and output devices for establishing a vehicle-carried warning system in which an event changing at least one input status causes a CAN message to be broadcast over the CAN bus to change at least one output status. Behavioral equations map input(s) to output(s), thereby resulting in desired actions. Also disclosed is a graphical user interface (GUI) for configuring the behavioral equations.
