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.

Claims8

Dependent claims

A vehicle comprising:

an engine configured to generate driving force;
a motor-generator configured to generate driving force;
a battery electrically coupled to the motor-generator;
an electric supercharger configured to compress air by using electric power supplied by the battery and to supply the compressed air to the engine;
a navigation device configured to determine a route that is a projected path of travel of the vehicle;
and
a control device comprising at least one processor and at least one memory coupled to the at least one processor, wherein
the at least one processor is configured to perform processing comprising:
identifying a downhill section in which a downhill slope on the determined route is located;
while the vehicle is traveling the identified downhill section, determining an endpoint estimated state of charge based on a state of charge of the battery at present time, the endpoint estimated state of charge being an estimated value of the 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 state-of-charge reference value.
