Industrial vehicle and method for controlling industrial vehicle
An industrial vehicle that includes an engine, a hydraulic actuator, a hydraulic pump, and an instruction member operated to instruct operation of the hydraulic actuator. A supply passage supplies hydraulic oil to the hydraulic actuator. A return passage returns return the hydraulic oil to an oil tank. A controller compares an engine speed and a predetermined comparison threshold value. When the engine speed is less than the comparison threshold value, the controller opens the return passage. The comparison threshold value includes a first threshold value and a second threshold value that is lower than the first threshold value. In response to the operation of the instruction member, the controller opens the return passage, performs revving control to increase the engine speed, and changes the comparison threshold value from the first threshold value to the second threshold value.
