Abstract
A vehicle is equipped with an internal combustion engine having a forced-induction apparatus with variable boost pressure, a first motor generator for generating electricity while applying negative torque to the engine, and a battery for storing the electricity generated by the first motor generator. During the operation of the engine, a target boost pressure is set lower as the rotational speed of the first motor generator is increased. The engine is controlled such that, with the boost pressure adjusted to the target boost pressure, the output torque of the engine has a required value determined by the accelerator operation amount. Further, while the output torque of the engine is adjusted to the required value, the magnitude of the negative torque by the first motor generator acting on the engine is adjusted such that the engine rotational speed has a target value.
