Abstract
A vehicle includes an internal combustion engine, a first rotating electric machine starting the internal combustion engine, a power control unit for operating the first rotating electric machine, a power storage device for supplying electric power to the power control unit, and a control device controlling the power control unit such that a voltage of the power storage device does not fall below a lower limit. When a change condition including a condition that the internal combustion engine is being operated is met, the control device sets the lower limit at a value lower than while the internal combustion engine is at a stop. Preferably, the change condition further includes a condition that a magnitude of voltage change of the power storage device is less than or equal to a first threshold value in addition to the condition that the internal combustion engine is being operated.
