摘要

Automatic variable speed gearbox (100) comprises at least one forward gear represented by a switching scheme of switched switching elements (B1, B2, B3, K1, K2, K3) which is different to a further switching scheme of switched switching elements at the same speed ratios. An independent claim is also included for a control unit for actuating an automatic variable speed gearbox. Preferred Features: The gearbox is formed as a multiple stage planetary gear. First switching elements (K1, K2, K3) are formed as clutches and second switching elements (B1, B2, B3) are formed as brakes.
