PROBLEM TO BE SOLVED: To provide a control device for an idle stop vehicle in which an inclination range is changed to be small when predicted start-up time before an engine re-start is completed is long, in which an engine hardly comes to an automatic stop when road surface inclination exceeds a permission inclination range, and also, in which sliding down of a vehicle is surely prevented at the time of engine re-start after the engine is automatically stopped on a road surface within the permission inclination range.SOLUTION: By an idle stop control unit 14, start-up time from the re-start of an engine 3 until it comes to a complete explosion state is derived based on start-up frequency of a starter 6, voltage and temperature of a battery 2, and cooling water temperature of the engine 3. When the derived start-up time becomes longer than specified time, a permission inclination range of road surface inclination is changed to be small by the idle stop control unit 14. Thereby, control can be performed so that the engine 3 is not automatically stopped when the road surface inclination exceeds the permission inclination range after the change to be small, and also, re-start of the engine 3 after the automatic stop on the road surface within the permission inclination range is performed quickly, and sliding down of a vehicle at the time of engine re-start can be surely prevented. |
