Abstract
A vehicle equipped with a hydraulically-operated device includes an engine that drives the hydraulically-operated device, a temperature detection unit that detects a temperature of the engine or hydraulic oil and a control unit that controls the engine. The control unit is allowed to control torque of the engine in accordance with a predetermined specified torque limit value when the control unit is in an Eco-mode, and does not control the torque of the engine in accordance with the specified torque limit value in the Eco-mode when the temperature detected by the temperature detection unit is a predetermined specified release temperature or lower. The release temperature is set as a temperature at which output of the engine is hard to be stabilized.
Claims5
A vehicle equipped with a hydraulically-operated device comprising:
- an engine that drives the hydraulically-operated device;
- a temperature detection unit that detects a temperature of the engine or hydraulic oil;
- and
- a control unit that controls the engine, wherein
- the control unit is allowed to control torque of the engine in accordance with a predetermined specified torque limit value when the control unit is in an Eco-mode,
- the control unit controls the engine without controlling the torque of the engine in accordance with the specified torque limit value in the Eco-mode when the temperature detected by the temperature detection unit is at a predetermined release temperature or lower, and
- the release temperature is set as a temperature at which output of the engine is hard to be stabilized when the torque of the engine is controlled.
