Abstract
A control method of a work machine includes: calculating a maximum flow rate of hydraulic oil discharged from a hydraulic pump; calculating a first target speed of working equipment including a bucket based on an operation amount of an operation device operated for driving a plurality of hydraulic actuators to which the hydraulic oil discharged from the hydraulic pump is supplied to drive the working equipment and a distance between the bucket and a target excavation landform; calculating a second target speed of the working equipment based on the maximum flow rate, and the operation amount of the operation device and the distance between the bucket and the target excavation landform; and outputting a control signal for controlling the hydraulic actuators based on a smaller one of the first target speed and the second target speed.
