    摘要： An integrated shut-off valve unit for a hydraulic accumulator comprises primary and secondary shut-off valves. In a first closed state, where only the primary shut-off valve is closed, auxiliary portions of a hydraulic circuit are energized without energizing the power-producing portion. In a second closed state, both valves are closed, isolating all portions of the circuit. The valve unit is opened from the first closed state by equalizing pressure across the primary shut-off valve and commanding it open. The valve unit is opened from the second closed state by pumping fluid across the secondary valve toward the hydraulic accumulator.

    摘要： Motor vehicles are equipped with a center-closed power steering system to provide power steering assistance in engine-off conditions for reduced fuel consumption. The power steering system includes a hydraulic pump mechanically driven by the engine, a high pressure accumulator, a steering gearbox fluidly connected to the accumulator, and a center closed valve mechanically connected to a driver-operated steering wheel. The valve is configured to selectively control flow of pressurized fluid from the accumulator to the steering gearbox to provide power steering assistance.

    摘要： A method for operating a series hybrid vehicle is provided, in which an engine generates secondary power that is either stored or used as direct input energy by a secondary power source to provide motive power to the vehicle. Regenerative braking is used to convert kinetic energy of the vehicle into secondary energy, which is also stored. When the vehicle driver makes a power demand, the secondary power source is powered by secondary energy from an energy storage device, direct input energy generated by the engine, or both, depending on the amount of stored secondary energy in combination with vehicle speed. When in use, the power level at which the engine is operated is also determined on the basis of available stored energy and vehicle speed. At higher vehicle speeds, the amount of stored energy is allowed to be depleted in order to increase the available storage capacity for regenerative braking.
