  • Publication number: 20230095687
    Abstract: Systems, methods, and apparatuses can accurately determine proper payload transfer from a working implement of a working machine. Such systems, methods, and apparatuses can identify occurrence of a payload discharge event for the working implement; determine whether a position of the working implement at a time of the identification of the occurrence of the payload discharge event is in a preset working area or a preset discharge area; omit the payload discharge event from registration for a tally of discharge material payload amount under a first case where the position of the working implement is determined to be in the working area; and register the payload discharge event for the tally under a second case where the position of the work implement is determined to be in the discharge area. The tally of the discharge material payload amount may be increased by a load amount associated with the load discharge event.

  • Publication number: 20220298757
    Abstract: To reduce the burden of an operator when performing a task for identifying which posture information detection sensor is mounted on which front member in a construction machine where the posture information detection sensors are mounted on multiple front members constituting a working machine. An automatic identification system is provided which has an identification task start button for being operated to start an identification task, a front member control means for outputting a control instruction for driving and stopping multiple front members sequentially, individually, and automatically, and a sensor identification means for identifying IMU mounted on each front member based on changes of a detection value of IMU as said each front member is driven by the front member control means.

  • Patent number: 8689550
    Abstract: A hydraulic control system that includes a controller that controls the accumulator flow rate control valve and a discharge flow rate of the hydraulic pump, wherein the controller: determines a minimum value among an operation demand flow rate to be demanded by an operation amount of hydraulic actuator operating members, a pump flow rate to be determined by a discharge pressure of the hydraulic pump under a constant horsepower control and a maximum flow rate of the hydraulic pump such that the determined minimum value is an actuator supply flow rate to be supplied to the plurality of hydraulic actuators, and controls the discharge flow rate and the accumulator flow rate so as to supply the actuator supply flow rate corresponding to a total flow rate of the discharge flow rate and the accumulator flow rate.
