Abstract
Embodiments of the invention enhance the starting performance of an engine from an automatic stoppage state, in a vehicle with an automatic engine stopping and starting system mounted thereon. In an embodiment, an engine start judging unit detects the presence or absence of a vehicle starting operation on the basis of the status of a throttle switch in an automatic stoppage state of an engine, and, when the seating of the driver is confirmed based on the status of a seat switch, the engine is started. A basic injection amount calculating unit calculates a basic fuel injection amount Ton the basis of engine parameters such as the engine cooling water temperature Tand the engine speed N. An injection amount increasing unit performs a control to increase the fuel injection amount at the time of starting the engine from the automatic stoppage state of the engine, based on the throttle opening detected by a throttle sensor.
