Hybrid vehicle and method of controlling hybrid vehicle

A method of controlling a hybrid vehicle, the hybrid vehicle including an engine, a motor connected to an output shaft of the engine, a power storage device configured to supply and receive electric power to and from the motor, and an electronic control unit,

• the method comprising:
• providing, by the electronic control unit, route guidance of a scheduled traveling route;
• performing, by the electronic control unit, charge control for controlling the engine and the motor such that a power storage ratio of the power storage device when the electronic control unit determines that the scheduled traveling route includes a traffic congestion zone based on traffic congestion information is higher than a power storage ratio of the power storage device when the electronic control unit determines that the scheduled traveling route does not include the traffic congestion zone based on the traffic congestion information, from a first point in time at which the hybrid vehicle passes a first location located before a start of the traffic congestion zone, to a second point in time at which the hybrid vehicle passes a predetermined location;
• and
• continuing, by the electronic control unit, execution of the charge control until the hybrid vehicle passes a branch point, which is a location at which the scheduled traveling route is divided into a congestion go-through route and a congestion avoidance route, when the electronic control unit changes the scheduled traveling route from the congestion go-through route including the traffic congestion zone, to the congestion avoidance route for avoiding the traffic congestion zone by traveling on a route different from the congestion go-through route, during execution of the charge control.
