Abstract

Upon starting an internal combustion engine for a hybrid vehicle, when the motor revolution speed, transmitted to an engagement device, is equal to or lower than the idle revolution speed of the internal combustion engine, if an engagement ratio is less than 1, the lower the engagement ratio is, the larger the engagement capacity is set, and if the engagement ratio is 1 or more, the engagement capacity is set to 0, wherein the engagement ratio is defined by a ratio of the internal combustion engine revolution speed with respect to the motor revolution speed. When the motor revolution speed is greater than the idle revolution speed, if an idle revolution ratio is less than 1, the lower the idle revolution ratio is, the larger the engagement capacity is set, and if the idle revolution ratio is 1 or more, the engagement capacity is set to 0.
