摘要： A powertrain for transmitting power in a vehicle includes a prime mover having a relatively slow transient response, and a storage device for storing energy in a predetermined form. A transmission includes an input driveably connected to the prime mover and an output driveably connected to vehicle drive wheels, producing a range of ratios of a speed of the output to a speed of the input that varies from negative to positive and includes zero. An energy conversion device, driveably connected to the prime mover and drive wheels, converts rotational power transmitted to the energy conversion device from the wheels and the prime mover to a form of energy that can be stored in the storage device, and drives the wheels using energy supplied to the energy conversion device from the storage device. A control device alternately transmits energy from the storage device to the energy conversion device, and transmits energy from the energy conversion device to the storage device.

摘要： A system according to this invention for transmitting power hydraulically to and from the wheels of a motor vehicle includes an accumulator containing fluid at relatively high pressure, a reservoir containing fluid at lower pressure, and a pump/motor driveably connected to the wheels and having an inlet, an outlet, and a variable volumetric displacement for pumping fluid between the accumulator and the reservoir. A first circuit connects the inlet to the reservoir and the outlet to the accumulator. A second circuit, which connects the inlet to the accumulator and the outlet to the reservoir, includes a first path having a low flow rate capacity, a second path having a higher flow rate capacity. A controller switches between pumping operation and motoring operation, opens and closes the first path during motoring operation, and reduces the displacement before switching between pumping operation and motoring operation. The first path includes a first valve responsive to the controller for opening and closing a connection between the accumulator and the inlet, and a first orifice arranged in series with the first valve having a relatively low flow rate capacity. The second path, arranged in parallel with the first path between the accumulator and the inlet, includes a second valve responsive to the controller for opening and closing a connection between the accumulator and the inlet, and a second orifice arranged in series with the second valve having a higher flow rate capacity than that of the first orifice.
