Benefits of technology

[0022]According to the vehicle control apparatus of the present invention, it becomes possible to accurately transmit information regarding an oil pressure anomaly to the driver even when the engine is automatically shut down by the idle-stop function during execution of a notification operation upon the occurrence of an oil pressure anomaly during operation of the engine, whereby unnecessary anxiety for the driver is avoided.

Problems solved by technology

Therefore, even when the oil pressure is normal immediately before the engine shutdown, there is a possibility that it may be determined that an oil pressure anomaly has occurred and a notification operation for an oil pressure anomaly may be performed.
In this case, it is a mistake to make an oil pressure anomaly notification.

Embodiment Construction

[0047]Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0048]FIGS. 1 to 6 show an embodiment of the present invention. Before describing an embodiment to which a feature of the present invention is applied, an overview of a configuration of the drivetrain of a vehicle to which the present invention is applied will be described with reference to FIG. 1.

[0049]The drivetrain includes an engine 1 as a motive power source, an automatic transmission 2 and a vehicle control apparatus 3.

[0050]The engine 1 is, for example, a gasoline engine in which an air-fuel mixture of intake air adjusted by an electronic control throttle 5 and fuel injected from an injector 6 mixed at an appropriate ratio is supplied to a combustion chamber, and is burnt with a spark plug ignited by an igniter 7, thereby generating rotational power. The engine 1 may be a diesel engine.

[0051]To start the engine 1, the engine 1 is cranked by rotatio...

Abstract

A vehicle control apparatus 3 according to an embodiment of the present invention is incorporated in a vehicle equipped with an engine 1 that is configured such that a lubricating oil and a working oil are circulated inside the engine 1 by an oil pump 9 driven by a crankshaft 1a. An oil pressure monitoring function performed by the vehicle control apparatus 3 maintains a notification operation for an oil pressure anomaly, even when the engine 1 is automatically shut down by an idle-stop function during execution of the notification operation.

Description

TECHNICAL FIELD[0001]The present invention relates to a vehicle control apparatus of a vehicle equipped with an engine in which a lubricating oil and a working oil are circulated by an oil pump driven by a crankshaft, and in particular to an improvement in an oil pressure monitoring function.BACKGROUND ART[0002]Some conventional vehicles are equipped with an idle-stop function (or also called an eco-run function) in order to suppress the amount of fuel consumed and reduce the amount of exhaust gas emitted (see, for example, Patent Literature 1).[0003]Such an idle-stop function is provided, for example, in an ordinary vehicle equipped with a gasoline engine, a diesel engine or the like, to automatically shut down an engine when the vehicle temporarily stops for, for example, a traffic light or another reason (when a prescribed automatic shutdown condition is satisfied) and restart the engine when the vehicle then starts off (when a prescribed restart condition is satisfied).[0004]A p...
