Abstract
At the time of an engine start while the vehicle is driving, when a required vehicle driving force (TRQ) is smaller than or equal to a predetermined value (TRQth), an electronic control unit (20) estimates that the degree of deformation of a mount (11) is smaller than or equal to a predetermined degree and sets a second-cycle fuel injection amount (Q2) so as to be larger than a first-cycle fuel injection amount (Q1) at the time of the engine start. On the other hand, when the required vehicle driving force (TRQ) is larger than the predetermined value (TRQth), the electronic control unit (20) estimates that the degree of deformation of the mount (11) is larger than the predetermined degree and sets the first-cycle fuel injection amount (Q1) so as to be larger than the second-cycle fuel injection amount (Q2) at the time of the engine start.
