      SOLUTION: When an automobile is traveling on a road surface with a low friction coefficient upon a shift of an engine 1 to idle operation in the process of stopping the automobile from traveling, a target rotating speed is reduced by a value equivalent to a reduction in a drive request value for any auxiliary at a time point corresponding to start of reduction of the drive request value, so that the automobile stops travelling promptly without stalling the engine 1. The engine is not stalled at that time because such disturbing action to drive wheels 6 about a rotation stopping direction as external force against the drive wheels 6 from the road surface side is applied in a direction opposite to a rotation direction is reduced on the road surface with the low friction coefficient, so that the engine speed is rarely reduced due to the disturbing action.

    • PROBLEM TO BE SOLVED: To improve combustibility and exhaust property by properly setting a timing of jetting a fuel into a cylinder when an engine is cool.
      SOLUTION: When the engine is cool (engine water temperature Teg ≤ reference temperature Tth), a DI start angle θ indicating the start timing of the injection of fuel into the cylinder is determined according to the cooling water temperature and load factor of the engine. The DI start angle θ is set to an advance-angle side according to a reduction in the temperature of cooling water considering the fact that the fuel becomes difficult as the temperature of the cooling water is lowered and the combustibility is deteriorated. Further, the fuel injection amount becomes larger as the engine load is increased, the DI start angle θ is set to a retard-angle side according to an increase in the load factor of the engine considering the fact that the adhered amount of fuel to the top face of the piston is increased when the fuel is jetted at a timing when the top face of the piston is nearer the injector 110 for cylinder injection.
