Abstract
A CVT transmission including a start-up element, a variator, and a direct-shift stage for switching between a first operating range (low) and a second operating range (high). A maximum transmission ratio of the second operating range (high) corresponds to a minimum transmission ratio of the first operating range (low). The transmission ratio ranges are arranged so that the marginal variator transmission ratio ranges, which constitute low-efficiency ranges, are not used.
