A method for controlling a hybrid vehicle, the hybrid vehicle including an engine, a power-generating motor generator that is driven by the engine and generates electric power, a traveling motor generator, and a battery that is charged by the electric power generated by the power-generating motor generator and supplies the electric power to the traveling motor generator, the method for controlling a hybrid vehicle comprising: executing, by a controller, a state of charge reducing control in which a state of charge of the battery at a time point at which the hybrid vehicle reaches a destination is lower than an upper limit state of charge by providing a section for executing an EV mode in which the engine is stopped and the hybrid vehicle travels by the traveling motor generator until the hybrid vehicle reaches the destination, characterized in that, during execution of the state of charge reducing control, when the hybrid vehicle is capable of reaching the destination in the EV mode, if an estimated value of a lowest temperature of an engine coolant until the hybrid vehicle reaches the destination, assuming that the EV mode is continued to the destination, is equal to or higher than a first threshold value, the controller starts the EV mode when the EV mode is continuable to the destination and executes the EV mode until the hybrid vehicle reaches the destination, and if the estimated value of the lowest temperature is lower than the first threshold value, the controller shortens a section for executing the EV mode compared to when the estimated value of the lowest temperature is equal to or higher than the first threshold value. the hybrid vehicle including an engine, a power-generating motor generator that is driven by the engine and generates electric power, a traveling motor generator, and a battery that is charged by the electric power generated by the power-generating motor generator and supplies the electric power to the traveling motor generator, the method for controlling a hybrid vehicle comprising: executing, by a controller, a state of charge reducing control in which a state of charge of the battery at a time point at which the hybrid vehicle reaches a destination is lower than an upper limit state of charge by providing a section for executing an EV mode in which the engine is stopped and the hybrid vehicle travels by the traveling motor generator until the hybrid vehicle reaches the destination, characterized in that, during execution of the state of charge reducing control, when the hybrid vehicle is capable of reaching the destination in the EV mode, if an estimated value of a lowest temperature of an engine coolant until the hybrid vehicle reaches the destination, assuming that the EV mode is continued to the destination, is equal to or higher than a first threshold value, the controller starts the EV mode when the EV mode is continuable to the destination and executes the EV mode until the hybrid vehicle reaches the destination, and if the estimated value of the lowest temperature is lower than the first threshold value, the controller shortens a section for executing the EV mode compared to when the estimated value of the lowest temperature is equal to or higher than the first threshold value. executing, by a controller, a state of charge reducing control in which a state of charge of the battery at a time point at which the hybrid vehicle reaches a destination is lower than an upper limit state of charge by providing a section for executing an EV mode in which the engine is stopped and the hybrid vehicle travels by the traveling motor generator until the hybrid vehicle reaches the destination, characterized in that, during execution of the state of charge reducing control, when the hybrid vehicle is capable of reaching the destination in the EV mode, if an estimated value of a lowest temperature of an engine coolant until the hybrid vehicle reaches the destination, assuming that the EV mode is continued to the destination, is equal to or higher than a first threshold value, the controller starts the EV mode when the EV mode is continuable to the destination and executes the EV mode until the hybrid vehicle reaches the destination, and if the estimated value of the lowest temperature is lower than the first threshold value, the controller shortens a section for executing the EV mode compared to when the estimated value of the lowest temperature is equal to or higher than the first threshold value.
