Abstract
In a hybrid vehicle including an engine, a motor driven by a battery output, and a continuously variable transmission, when acceleration is requested, an ECU executes feeling-of-acceleration producing control for gradually increasing an engine rotation speed from an initial value NEini lower than an optimum rotation speed. With the battery output, the ECU makes up for a shortfall of engine output caused by the feeling-of-acceleration producing control. When starting the feeling-of-acceleration producing control, the ECU calculates a basic initial value NEini_base lower than the optimum rotation speed, and calculates, based on an atmospheric pressure, a lower limit value NEmin that allows the battery output to be maintained to be equal to or lower than prescribed electric power. The ECU selects a larger one of basic initial value NEini_base and lower limit value NEmin as initial value NEini.
