Abstract
A vehicle brake system includes first and second central control units communicating with, respectively, first and second control networks, and a plurality of brake units. Each brake unit includes a brake component, a self-enforcing mechanism associated with and acting upon the brake component, and first and second actuation mechanisms acting upon the self enforcing mechanism, in response to, respectively, first and second actuation control signals, to cause actuation of the brake component. Each brake unit also includes first and second local control units in direct communication with, respectively, the first and second central control units via, respectively, the first and second control networks. The first and second local control units are in communication with, respectively, the first and second actuation mechanisms and transmit, respectively, the first and second actuation control signals to, respectively, the first and second actuation mechanisms, under certain circumstances, to cause actuation of the brake component.
