Working machine control method, working machine control program, working machine control system, and working machine

Abstract

A control method of a working machine is a control method of the working machine including an electric motor driven by electric power of a battery and a hydraulic pump driven by the electric motor and configured to supply hydraulic oil to a hydraulic actuator. This control method includes: driving the electric motor at a steady rotation speed when a monitored temperature is in a normal temperature region; and setting an upper limit value of a rotation speed of the electric motor to a regulated rotation speed lower than the steady rotation speed when the monitored temperature is in a low temperature region lower than the normal temperature region.
