Abstract
A method of controlling an oil pressure system according to an aspect of the disclosure includes: a comparison step of comparing a measured load (engine torque calculation value) of an oil pressure system driven by an oil pressure pump with an allowable load of the oil pressure system (allowable engine torque value); and a control step of controlling a flow rate of the oil pressure pump based on a result of comparison between the measured load and the allowable load.
