    摘要: Torque control for a construction machine three-pump system that can accurately control the total absorption torque of first, second, and third hydraulic pumps and effectively use the output torque of an engine. A pump base torque computation section 42 calculates a pump base torque Tr from a target rotation speed. A subtraction section 44 calculates a reference value Tf for the maximum absorption torque available to the first and second hydraulic pumps 2, 3 by subtracting a third pump reference absorption torque T3r from the pump base torque Tr. A correction torque computation section 45 calculates a correction torque value from the delivery pressure of the third hydraulic pump 4. An addition section 46 calculates a target absorption torque Tn by adding the correction torque value Tm to the reference value Tf. A first regulator 31 is controlled so as to obtain the target absorption torque Tn.

    摘要: Each time a starting process for a diesel engine 2 is conducted and before the diesel engine 2 is started, any differences of the pressures P1 and P2 detected by first and second pressure sensors 21 and 22, respectively, with respect to a predetermined reference pressure value Pref, are computed and stored as first and second correction values ΔP1 and ΔP2, and then a differential pressure P12 across a particulate filter in the diesel engine 2 is computed using the pressure detection results of the first and second pressure sensors 21, 22 and the first and second correction values ΔP1, ΔP2. Thus, use of simply constructed and highly durable sensors during the detection of the differential pressure existing across the filter allows accurate measurement of this differential pressure.

    摘要: An exhaust gas cleaning system for an engineering vehicle, such as a hydraulic excavator, is capable of performing manual regeneration control of a regeneration fuel injector 40 that is started only under the following conditions: a manual regeneration starting switch 39 is enabled; an engine control dial 2 commands a low-speed idle revolution speed; and a gate lock lever 22 is switched to a second position B at which generation of control pilot pressures a through f by use of remote control valves 25, 26, and 27 is disabled. Even when the manual regeneration control is being executed, if the gate lock lever 22 is switched to a first position A, the manual regeneration control immediately ends. As a result, the manual regeneration control of a filter for collecting particulate matter included in the exhaust gas and the operation of the work system do not influence each other.

    摘要: A work machine gear shifting control system provides gear shifting conditions for an automatic gear shifting mode in accordance with work site conditions. An area 62 of a display device 49 displays a permissible velocity setting range and setup operation guidance, and another area 64 shows guidance to indicate whether the setting is acceptable or unacceptable. When the traveling velocity falls within the permissible velocity setting range, the displayed guidance changes to indicate that the setting is acceptable. When, in this instance, an operator presses a setup switch 23 with desired timing, a transmission gear shifting control section 45 acquires the prevailing vehicle velocity and velocity ratio (or vehicle velocity), and stores adjustment values in an adjustment value storage section 43 so that the vehicle velocity and velocity ratio become the gear shifting control threshold values for normal gear shifting control (steps S535 to S545).
