Abstract
In response to a start request of an engine in setting of a gearshift position SP to a drive (D) position, the control procedure sets a relatively small value Nto a threshold value Nref (step S) and starts fuel injection and ignition of the engine when a rotation speed Ne of the engine reaches or exceeds the threshold value Nref (=N) (steps Sto S). This ensures a quick start of the engine. In response to a start request of the engine in setting of the gearshift position SP to a parking (P) position, on the other hand, the control procedure sets a greater value Nthan the value Nto the threshold value Nref (step S) and starts fuel injection and ignition of the engine when the rotation speed Ne of the engine reaches or exceeds the threshold value Nref (=N) (steps Sto S). This effectively reduces potential vibrations at a start of the engine.
