Abstract
A control system of a hybrid vehicle includes an internal combustion engine loaded on a vehicle, an electric motor loaded on the vehicle, and connected to wheels via a power transmission mechanism, a battery storing power that drives the electric motor, and a control device that controls engine torque generated by the internal combustion engine, and motor torque transmitted to the wheels by the electric motor. The control device calculates an outputable power of the battery based on a temperature and a state of charge of the battery. The control device is configured to make a torque change amount of the engine torque larger when the calculated outputable power belongs to a predetermined low power region than when the outputable power belongs to a high power region with higher power than the low power region.
