Abstract:
An engine automatic start stop control apparatus that controls an engine to be automatically stopped or started in response to driving conditions of a vehicle, comprising:an outside air temperature determining device for detecting air temperature at a location which represents outside air temperature of the vehicle; an engine water temperature detecting device for detecting engine water temperature of the engine; a determination device for making a determination whether or not to allow stoppage of the engine on the basis of a relationship between the determined outside air temperature and the engine water temperature; and an intake air temperature detecting device which is installed inside of an intake air passage of the engine to detect intake air temperature, so that the outside air temperature determining device estimates the outside air temperature based on the intake air temperature which is detected by the intake air temperature detecting device after the vehicle runs for a prescribed time.
