CONTROL APPARATUS FOR HYBRID VEHICLE

A control apparatus for a hybrid vehicle controls the hybrid vehicle including an engine and an electric motor. The engine includes a supercharger, and a blow-by gas treatment device including a ventilation line and a fresh air line and causing blow-by gas to be introduced into an intake system and combusted. The electric motor transmits torque to the engine. The control apparatus includes a control unit that controls driving of each of the engine and the electric motor. The control unit causes the electric motor to be in regenerative operation without decreasing an output torque of the engine in one or both of a case where a boost pressure decreases to a predetermined threshold or below and a case where an accelerator position decreases, in a situation where an outside air temperature is lower than or equal to a predetermined temperature and where the boost pressure is positive.
