摘要： A series hydraulic hybrid driveline for a vehicle, having a hydraulic circuit with a first hydraulic displacement unit in fluid communication with a second hydraulic displacement unit, the first hydraulic displacement unit having a variable hydraulic displacement and the first hydraulic displacement unit being drivingly engaged with an internal combustion engine. A hydraulic accumulator assembly selectively fluidly connected to the hydraulic circuit, the hydraulic accumulator assembly having a high pressure hydraulic accumulator and a low pressure hydraulic accumulator. And a hydraulic actuator adapted to control the hydraulic displacement of the first hydraulic displacement unit, the hydraulic actuator being in fluid communication with the hydraulic accumulator assembly and/or with the hydraulic circuit. A method of shutting down an engine of a series hydraulic hybrid driveline and of re-starting the engine of a series hydraulic hybrid driveline using energy stored in a hydraulic accumulator assembly is also described.
