ABSTRACT:
A controller area network employs a CAN bus for facilitating CAN communications among a plurality of communication controllers switched to an active state. The controller area network further employs a CAN wake-up controller for switching one or more communication controllers to the active state in response to an application of a non-interfering communication biasing signal to said CAN bus. Upon a termination of the application of a non-interfering communication biasing signal to said CAN bus, the CAN wake-up controller switches the communication controller(s) to an inactive state for impeding CAN communications by communication controller(s) via the CAN bus.
