摘要： A modification torque ΔT and a torque converter speed ratio e is computed from input and output revolution speeds of a torque converter 31. A first determination coefficient α corresponding to the speed ratio e, and a second determination coefficient β corresponding to a pump pressure are computed. A selector 87 selects the smaller one of these coefficients as a determination coefficient γ, and the modification torque ΔT is multiplied by γ to provide a modification torque ΔTA. An adder 89 adds the modification torque ΔTA (negative value) to a pump base torque TR to provide a modified pump base torque TRA, whereby a maximum pump absorption torque TRA is controlled so as to become TRA. The maximum pump torque reducing control can then be performed while accurately confirming a work situation during the combined operation of travel and a working actuator.

摘要： A hydraulic excavator 1 working in fields includes a controller 2 for measuring a working time for each of an engine 32, a front 15, a swing body 13, and a travel body 12, storing measured data in a memory of the controller 2, and then transferring it to a base station computer 3 via satellite communication, an FD, etc. The transferred data is stored as a database 100 in the base station computer 3. The base station computer 3 reads the data stored in the database 100 for each hydraulic excavator, calculates a working time of a part belonging to each section on the basis of the working time of that section, and compares the calculated working time with a preset target replacement time interval of the relevant part, thereby calculating a remaining time up to next replacement of the relevant part and managing the scheduled replacement timing thereof. Thus, the appropriate scheduled replacement timing of parts can be determined even in a construction machine having a plurality of sections that differ in working time from each other.

摘要： A control system wherein a reverse characteristic having a reverse input/output relationship to a target input/output characteristic of a control object, is preset, and a target value for an output of the control object is calculated. A command signal corresponding to the target value then is determined based on the preset reverse characteristic, and the command signal is output to the control object. The control system includes first means for calculating a command signal corresponding to a given target value for the output of the control object based on the preset reverse characteristic, outputting the command signal to the control object, measuring an output of the control object and estimating a deviation between an actual input/output characteristic of the control object and the target input/output characteristic therefor, and storing data on the deviation between the input/output characteristics as learning correction data. The control system further includes second means for reading out the stored learning correction data and correcting the command signal using the learning correction data.
