Abstract

During the stop of the internal combustion engine, engine stop is controlled so that, among the plurality of cylinders of the internal combustion engine, a cylinder arranged at a position close to the transmission stops in the compression stroke. More specifically, at the point of time when the rotational speed of the internal combustion engine becomes smaller than a predetermined value during the process of stopping the internal combustion engine (step ST3), the remaining rotational angle before cylinder #4 close to the transmission stops in the compression stroke is calculated ( ST5). Based on the calculated value of the remaining rotation angle, a motor (for example, a motor generator) is drive-controlled to forcibly drive the crankshaft of the internal combustion engine (ST6), so that cylinder #4 closest to the transmission stops in the compression stroke.

Description

technical field [0001] The present invention relates to a control device for an internal combustion engine, and more particularly, to a control device for controlling a stop position of an internal combustion engine and an automobile provided with the control device. Background technique [0002] In recent years, in consideration of environmental protection, in order to improve fuel economy and reduce emissions, automobiles equipped with internal combustion engines (also called engines) have adopted the method of stopping combustion of the engine when predetermined conditions are met, such as when the automobile stops at a red light at an intersection. Idle stop control that stops the engine by supplying fuel to the chamber (cutting off the fuel). [0003] In addition, in a state where the engine is stopped by such idling stop, when a predetermined engine start condition is satisfied, the engine is restarted by an electric motor such as a starter motor (starter). Vehicles e...
