The invention refers to a hydraulic driveline (1) for a vehicle. The hydraulic driveline comprises a main
hydraulic circuit (8) with a first hydraulic displacement unit (4) which is fluidly connectedwith a second hydraulic displacement unit (5), said second hydraulic displacement unit (5) forming a primary
hydraulic load of the driveline, the first hydraulic displacement unit (4) being drivinglyconnected with a
combustion engine (3). The driveline further comprises a
hydraulic accumulator assembly (6a, 6b) which is selectively fluidly connected to the main
hydraulic circuit by one or more controllable valves (HPA, HPB, LPA, LPB) of a first group of valves, wherein the driveline further comprises a first secondary module (28, 28') that comprises a first fluid communication (23, 23', 24, 24') of the
hydraulic accumulator assembly (6a, 6b) with a first secondary
hydraulic load (27, 37) of the hydraulic driveline. The first fluid communication comprises one or more controllable valves (20, 20', 21, 21', 22) that allow connecting the
hydraulic accumulator assembly (6a, 6b) with the first secondary load (27, 37) or separating the hydraulic accumulator assembly (6a, 6b) from the first secondary load and that belong to a second group of valves, wherein the controllable valves of the second group of valves are controllable independently of the controllable valves of the first group ofvalves.
