Abstract
A hydraulic control device includes: a virtual bleed information output unit that outputs virtual bleed information indicating a state of hydraulic oil flowing through a virtual bleed circuit based on an operation amount of an operation tool, a discharge pressure of a hydraulic pump, and a preset virtual bleed characteristic that is a characteristic of the virtual bleed circuit; a required bleed information output unit that outputs required bleed information indicating the state of hydraulic oil flowing through the virtual bleed circuit that is required to cause the hydraulic actuator to perform a desired operation based on the operation amount; a target control value determination unit that determines a target control value for the hydraulic pump based on a comparison result between the virtual bleed information and the required bleed information; and a pump control unit that controls the hydraulic pump on the target control value.
