The invention provides a control device for a continuously variable transmission, the continuously variable transmission and vehicles with the same, and avoids reduction of driving comfort caused by idling of a primary belt wheel relative to a belt during acceleration. The transmission (20) comprises an input shaft (12), an output shaft (13), the primary belt wheel (23) rotating along with the input shaft (12), and the belt (25) wound around the primary belt wheel (23) and a secondary belt wheel (24). The transmission (20) comprises an electric motor (22) through driving a movable belt wheel (23a) of the primary belt wheel (23) to change variation ratio. The control device (ECU5) of the transmission (20) comprises a rotary secondary belt wheel rotating speed sensor (28) of a detection tape (25), and a control part (55) of the ECU (5) controls the position of the belt wheel after being started to detect out the rotation of the tape (25), namely, normal control of the variation ratio. |
