A fluidic control system 1 for controlling a vehicle is provided. The fluidic control system includes a controller 2 and a closed fluidic circuit. The circuit comprises: a pump 3 for pressurising 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, 5, 6 is fluidly connected to the valve means 40, 50, 60 for selectively receiving pressurised fluid therefrom. The precharge accumulator 7 includes a movable member (73, Figure 2) that defines 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.
