摘要： A dual drive driveline for a vehicle has a power source, a hydrostatic pump drivingly engaged with the power source, a first axle, a second axle, and a first hydrostatic unit in fluid communication with the hydrostatic pump. The first hydrostatic unit is drivingly engaged or selectively drivingly engaged with the first axle, and the first hydrostatic unit is not drivingly engageable with the second axle. A second hydrostatic unit in fluid communication with the hydrostatic pump, the second hydrostatic unit being drivingly engaged or selectively drivingly engaged with the second axle, and the second hydrostatic unit not being drivingly engageable with the first axle. A control unit is adapted to control a hydraulic displacement of at least one of the hydrostatic pump, the first hydrostatic unit and the second hydrostatic unit.

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.
