Abstract
A vehicle includes: an engine that generates driving force; a motor-generator that generates driving force; a battery electrically coupled to the motor-generator; an electric supercharger that compresses air with electric power supplied by the battery and to supply the compressed air to the engine; a navigation device that determines a route; and a control device including at least one processor and at least one memory coupled to the processor. The at least one processor performs processing including: identifying a downhill section in which a downhill slope on the route is located; determining, based on a state of charge of the battery at present time, an endpoint estimated state of charge of the battery at a point in time when the vehicle reaches an endpoint of the downhill section; and turning on the electric supercharger when the endpoint estimated state of charge is greater than or equal to a predetermined value.
