Abstract: A shovel includes a first pump 14L; a second pump 14R; a hydraulic swing motor 21; a pump/motor 14A configured to generate an engine-assist torque in response to hydraulic oil from the hydraulic swing motor 21 during swing deceleration; an accumulator 80 configured to accumulate the hydraulic oil flowing out of the hydraulic swing motor 21 during swing deceleration; a regeneration valve 22G configured to switch open/close of transfer from a discharge port 21L to the pump/motor 14A and the accumulator 80; and a controller configured to control the regeneration valve 22G. During swing deceleration, the controller adjusts an open area of the regeneration valve 22G in such a way that a swing flowing-out pressure becomes a swing braking target pressure, and causes the hydraulic oil flowing out of the hydraulic swing motor 21 to flow into the pump/motor 14A and the accumulator 80 at the same pressure.

Abstract: An online method for reconfiguring pressure and position sensors in a hydraulic system is disclosed. In one step, a sensor drift condition, a recalibration request, or an unisolated fault condition is detected. In another step, a system pressure sensor or another sensor, such as a load-sense pressure sensor, is verified as a trusted master reference sensor. Another step includes measuring and recording a first pressure reading at the master reference sensor and first voltage readings associated with first, second, third, and fourth pressure slave sensors at a first pump pressure set point. Another step includes, repeating the previous step at a second pump pressure set point. A new gain and offset for each of the first, second, third, and fourth pressure sensors can be calculated based on a comparison of the recoded first and second pressure readings and the recorded first and second voltage readings.
