Embodiment Construction

[0029] Below, refer to Figure 1 to Figure 5 An embodiment in which the internal combustion engine control device according to the present invention is embodied as an internal combustion engine control device for overall control of an internal combustion engine mounted on a vehicle will be described. figure 1 It shows the schematic structure of the oil pressure supply system of the internal combustion engine in this embodiment.

[0030] The hydraulic supply system in this embodiment includes an internal combustion engine-driven pump 20 connected to the internal combustion engine 10. figure 1 On the output shaft 11 indicated by the dotted line. In the hydraulic supply system, the pump 20 is driven by the driving force of the internal combustion engine 10, and the lubricating oil stored in the oil pan 22 is pressurized and fed by the pump 20, thereby supplying the lubricating oil to the A system in each component of the internal combustion engine 10 that is lubricated.

Abstract

This electronic control device is utilized in an internal combustion engine equipped with an engine-driven pump, using the driving force of the internal combustion engine to circulate lubricating oil, and executing a low-pressure control which restricts the amount of lubricating oil that circulates when there is a small demand for lubricating oil, thereby reducing the driving load of the pump operating in the internal combustion engine. Furthermore, when a prescribed automatic stop condition is satisfied the operation of the engine is stopped automatically, and when a prescribed restart condition is satisfied during the automatic stop the internal combustion engine is restarted. Furthermore, when the internal combustion engine is started in response to the operation of the ignition switch, execution of the low-pressure control is prohibited, but execution of the low-pressure control is permitted when restarting the internal combustion engine.

Description

technical field [0001] The present invention relates to an internal combustion engine control device which is applied to an internal combustion engine having an internal combustion engine-driven pump, circulates lubricating oil using the driving force of the internal combustion engine, and is executed when the demand for lubricating oil is small. The limited low-pressure control of the circulation of lubricating oil reduces the driving load of the pump on the internal combustion engine. Background technique [0002] Conventionally, an internal combustion engine has an internal combustion engine-driven pump, and by driving the pump, lubricating oil circulates through various parts of the internal combustion engine. [0003] In addition, for example, Patent Document 1 discloses a structure in which a relief valve capable of changing the relief pressure is provided in the lubricating oil supply passage, and the relief pressure of the relief valve is changed when the demand for ...
