Gear-change system for an electronically controlled vehicle automatic gearbox

Abstract

A shifting device for an automatic transmission controlled by an electronic control device (2) for vehicles, especially for motor vehicles, is described, which has a first shifting device (4), in which different gears to be shifted automatically can be preselected by manual selection, and a second shifting device (9), which can be actuated by device of a selector device (5) and in which the selector device (5) is held in the neutral middle position, from which it can be moved by manual actuation in a first direction (15) for inducing upshiftings and in a second direction (16) for inducing downshiftings, wherein the shifting movements of the selector device (5) are detected by device of sensors and are sent as signals to the control device (2). The second selector device (5) has a shift position (−) for the selector device (5) for single downshifting into the next lower gear and another shift position (−−) for maximum downshifting into the gear with the lowest possible ratio and/or a shift position (+) for the selector device (5) for single upshifting into the next higher gear and another shift position (++) for maximum upshifting into the gear with the highest possible ratio.
