A fluidic control system (1) for controlling a vehicle, which includes a controller (2) and a closed fluidic circuit. The circuit includes a pump (3) for pressurizing fluid in the circuit, valve means (40, 50, 60), an actuator (4, 5, 6) and a precharge accumulator (7). The valve means (40, 50, 60) is fluidly connected to the inlet and outlet of the pump (3) and the actuator (4, 6) is fluidly connected to the valve means (40, 50, 60) for selectively receiving pressurized fluid therefrom. The precharge accumulator (7) includes a movable member (73, FIG. 2) that describes a variable volume (71) fluidly connected to the circuit between the valve means (40, 50, 60) and the inlet of the pump (3). The system (1) also includes a sensor (70) for determining the position of the movable member (73) for estimating the quantity of fluid and/or detecting an abnormal pressure variation within the circuit.
A fluidic control system comprising a controller and a closed fluidic circuit, the fluidic circuit comprising a pump having an inlet and an outlet, a valve assembly operatively connected to the controller and fluidly connected to the inlet and outlet of the pump, an actuator fluidly connected to the valve assembly for selectively receiving pressurised fluid therefrom and a bleed assembly fluidly connected between the valve assembly and the inlet of the pump, wherein the bleed assembly comprises an inlet port for fluidly connecting the inlet of the pump to a source of fluid, an outlet port for fluidly connecting the valve assembly to a discharge reservoir and a shutoff mechanism between the inlet port and the outlet port for selectively opening and closing fluid communication therebetween.
