<p>A hydraulic circuit is provided for a hydraulic by-wire vehicle braking system (10). There is a need for such a circuit which permits independent left and right brake operation and which has redundancy. The circuit includes left and right brake control valves (40, 50), a left brake line (69) communicated with a left brake (12L), a right brake line (79) communicated with a right brake (12R), and a left-right cross-over valve (80) operable to open and close communication between the left and right brake lines (69, 79). The hydraulic circuit also includes a left shutoff valve (60, 70) between an outlet of the left brake valve (40) and the left brake line (69), and a right shutoff valve (50) between an outlet of the right brake valve (79) and the right brake line (79).</p> |
