BRAKING SYSTEM WITH REDUNDANT TRAILER COMMUNICATION

Abstract

The present invention relates to a braking system with redundant trailer communication. In one embodiment, a braking control system for a tractor-trailer comprises a primary brake controller in a tractor configured to communicate with a trailer brake controller in a trailer via a first communication channel, and a redundant brake controller in the tractor configured to communicate with the trailer brake controller via a second communication channel. The primary brake controller is further configured to serve as the master brake controller for the trailer and to communicate with an automated driving computer in the tractor. The redundant brake controller is further configured to assume the role of master brake controller in response to the determination that the primary brake controller can no longer serve as the master brake controller.
