摘要： A vehicle includes a first motor (1), a second motor (2), a battery (5), a decider (11), a first calculator (12), a second calculator (13) and a controller (14). The decider (11) detects a state of the battery (5) and determines whether the detected state is a state where charging the battery (5) is restricted. The first calculator (12) calculates, when the first motor (1) generates the regenerative electric power under the state where charging the battery (5) is restricted, a target energy consumption representing a target value of electric power that the second motor (2) is to consume to drive the engine (3) by using the regenerative electric power. The second calculator (13) calculates an actual energy consumption that the second motor (2) requests to maintain rotating speed of the engine (3). The controller (14) adjusts angular acceleration of the engine (3) and the second motor (2), using a difference between the target energy consumption and the actual energy consumption.

摘要： A fuel injection control apparatus is included in an internal combustion engine including an intake passage injection valve (22) and a cylinder injection valve (21) and being capable of switching between an MP1 mode and a DI + MPI mode based on an operating state of the engine (1). The fuel injection control apparatus includes an injection amount control unit including a direct-combustion-rate calculation unit (33) calculating a DI direct combustion rate αdi that is the rate of that portion of the amount of DI injection Fdi which corresponds to a fuel combusted instead of adhering to inside of the cylinder, and a cylinder vaporization rate calculation unit (34) calculating a cylinder vaporization rate Z that is the rate of the amount of that portion of the fuel adhering to the inside of the cylinder which vaporizes. The injection amount calculation unit (32) controls fuel injection based at least on the DI direct combustion rate αdi and the cylinder vaporization rate. When the engine is switched between the MPI mode and the DI + MPI mode, the injection amount calculation unit (32) corrects the DI direct combustion rate αdi or the cylinder vaporization rate Z to set the amount of fuel injection to a value different from a value set in a case where the fuel injection modes are maintained.
