Abstract

A hybrid vehicle includes an internal combustion engine, electric motors, an electric supercharger, a battery, and a controller. The controller determines whether to increase a total electric power supply amount to the electric motor and the electric supercharger from the battery based on a state of charge of the battery. When so determined, electric power supply promotion control is performed to increase the total electric power supply amount from the battery. In the electric power supply promotion control, the controller controls the electric power supply amount to the electric motors and the electric supercharger so as to maximize fuel save rate, which is the percentage of decrease of the fuel consumption of an internal combustion engine relative to an increase in the total electric power supply amount from the battery.
