Abstract
By preventing engagement of an engaging part (clutch) under appropriate conditions, it is possible to effectively avoid the so-called surging phenomenon. When there is an engaging directive for the clutch, the rotational speed of the engaging element positioned at the output shaft side of the drive/regeneration motor (the clutch output rotational speed) is detected, and the gear ratio of the CVT is detected, and when the product of the rotational speed of the engaging element and the gear ratio of the CVT is equal to or below a predetermined value, complete engagement between the engaging elements is prevented, and control is conducted which makes the gear ratio large.
