  • Patent number: 10273660
    Abstract: The present disclosure relates to a hydraulic system of construction machinery and a method of controlling the hydraulic system. The hydraulic system of construction machinery and the method of controlling the hydraulic system according to the present disclosure assign a weighted value for each operation, preliminarily distribute a (available torque that can be used) value that an engine can provide, through torque weighted values for each operation, and calculate surplus torque and deficient torque by comparing a preliminary distributable torque value to required torque. The surplus torque is provided for an operation in which torque is deemed to be deficient. Thus, the hydraulic system of construction machinery and the method of controlling the hydraulic system according to the present disclosure can sufficiently use available torque that can be used so that an operator can achieve a desired level of performance during the operation.
