HYBRID VEHICLE AND METHOD OF CONTROLLING HYBRID VEHICLE

A vehicle includes: a motor generator; an engine having a forced induction device; and a HV-ECU. An operation region of the engine includes a PM generating region in which an amount of particulate matters included in exhaust gas of the engine is more than a predetermined amount due to a load of the engine being abruptly increased during boosting by the forced induction device. The PM generating region is a low-rotation and high-torque region. When assistance by the motor generator is sufficiently obtained and the engine is operated in the PM generating region, the HV-ECU restricts an increasing rate of the torque of the engine to be less than or equal to an upper limit rate. The HV-ECU complements, by the torque of the motor generator, the torque of the engine restricted by restricting the increasing rate of the torque of the engine.
