Zusammenfassung:	There is provided a vehicle comprising: a prime mover (102); a hydraulic fluid manifold (109); a hydraulic machine (104); a hydraulic accumulator (142, 144); one or more hydraulic actuators (112); a valve arrangement (126, 128, 138); and a controller. The controller is configured to receive an actuator demand signal indicative of a demand to move the one or more hydraulic actuators; and to control the hydraulic machine and the valve arrangement to cause movement of the one or more actuators in accordance with the actuator demand signal by bringing the hydraulic accumulator into fluid communication with a first actuator chamber (114) of the one or more hydraulic actuators, and to synchronise therewith changing a pressure in a second actuator chamber (116) of the one or more hydraulic actuators. The second actuator chamber is in fluid communication with the hydraulic machine.
