    Abstract: A swing drive system for a construction machine enhances safety for an operator. A swing control means 55A has a lever input amount-torque table 11 and an actual rotating speed-torque table 13.

The swing control means 55A further has a lever input amount-meter-out restriction area table 15 and an actual rotating speed-relief torque table 119. Based on the lever input amount and the actual rotating speed of the electric motor, a meter-out restriction area is derived from the lever input amount-meter-out restriction area table and the actual rotating speed to calculate a meter-out torque. A minimum value of the meter-out torque and relief torque is taken as the braking torque.

    Abstract: A drive system of an electrically driven dump truck is capable of achieving an operational feeling in which the operation amount of the accelerator pedal is well balanced with the output horsepower of the electric motors, particularly at the time of slow traveling. To achieve this, the target motor output horsepower Pm0 corresponding to the operation amount of an accelerator pedal 1 is calculated. The target motor torque Tr1R, Tr1L is calculated on the basis of the target motor output horsepower Pm0 and the rotational speed ?R, ?L of electric motors 12R, 12L respectively. The acceleration torque limit values of the electric motors 12R, 12L corresponding to the operation amount of the accelerator pedal 1 are calculated, respectively. Then, smaller values are selected, as motor torque instruction values TrR, TrL, between the acceleration torque limit value and the target motor torque Tr1R, Tr1L to control inverters 73R, 73L, respectively.

  • Patent number: 7475400
    Abstract: System (software) development is performed based on a state transition diagram. The workflow of a business process is partitioned for each event therein and assigns process codes to the respective process results. A process code is an identification code to indicate a certain state of a process. For example, a process code AA is assigned to the waiting state before completion of a process A, and a process code AB is assigned to the completion state thereof, wherein the process code AB is set as a condition to start a process B. The process codes that are set based on the state transition diagram are managed in an external database (DB) so that flexible modification of the state transition configuration and the state transition order is possible. This provides an entirely new method of system design that facilitates business process reengineering.
