A series hydraulic hybrid driveline for a vehicle is described. The driveline has a power source, a hydraulic circuit having a first hydraulic displacement unit and a second hydraulic displacement unit, a hydraulic accumulator assembly with high pressure and low pressure hydraulic accumulators, at least one accumulator valve, at least one input device, and a control unit. The first hydraulic displacement unit is drivingly engaged with the power source. The accumulator assembly is selectively fluidly connected to the hydraulic circuit through the accumulator valve. The control unit is configured to compute a total power requested from the power source based on an input command from the input device, compare the computed total power to a threshold power, and control a valve state of the accumulator valve based upon the result of the comparison. A method of controlling the driveline is also described.
