Abstract
An automatic stop/start-up control system of an engine, recognizes an early drop of a power assist for brakes while the engine is automatically stopped. The control system enables the will of a driving person to be adequately reflected and the driving person does not feel a sense of incongruity when braking. Accordingly, the automatic stop/start-up control apparatus automatically stops the engine when an automatic stop condition is satisfied while the engine is driven, and automatically starts up the engine when an automatic start-up condition is satisfied while start-up of the engine is stopped. The control apparatus includes a power assist detector to detect power assist of an underpressure assist type brake apparatus equipped in the vehicle and a controller to control so as to automatically start up the engine when a decreasing rate per unit time of power assist, which the power assist detector detects while the engine is automatically stopped, exceeds a first setting value.
