Abstract

An engine start control apparatus for a vehicle in which an engine can be automatically stopped temporarily is characterized in that when the position of a piston is within a range that is likely to cause ignition during automatic stop of the engine (Yes in step S3), it is predicted that the electric power consumed in a starting device in restarting the engine is small, a second path with a large resistance is selected as an energization path from a battery to a starter motor (step S4), and starter start for cranking the engine by the starting device and ignition start based on fuel injection and ignition are executed (step S5) to restart the engine.

Description

technical field [0001] The present invention relates to an engine start control device. Background technique [0002] Conventionally, there is known a control device that automatically stops an engine of a vehicle when a predetermined automatic stop condition is satisfied. [0003] For example, in Japanese Patent Application Laid-Open No. 2010-23660 (JP 2010-23660A), it is described that by using the cranking of the electric motor and the combustion of fuel when the restart is ready to be prompted during the automatic stop of the engine, and when the Restart the engine when the scheduled restart conditions are met only by cranking the electric motor when not ready to prompt restart during auto stop. [0004] It should be noted here that there is a concern that the electric motor (starter) deteriorates prematurely due to an increase in the frequency of use of the electric motor in the vehicle, in which Japanese Patent Application Laid-Open No. 2010-23660 (JP 2010-23660A) Th...
