A brake control system is provided for a utility vehicle having manned and unmanned operational modes. The brake control system includes a hydraulically operated brake. A manually operated brake circuit and an electro-hydraulic (E-H) brake circuit are connected to the brake. The E-H brake circuit includes a pump, a solenoid operated inlet valve, an accumulator, and first and second solenoid operated brake valve connected between the brake and the inlet valve. A first CPU is operatively connected to the inlet valve and to the first brake valve. A second CPU is operatively connected to the inlet valve and to the second brake valve. An accumulator pressure sensor senses the accumulator pressure. A brake pressure sensor senses brake pressure. The first and second CPUs control the inlet valve and the brake valves as a function of the sensed accumulator pressure and brake pressure. |
