Problems solved by technology

In the case of a rapid subsequent gear change (which typically occurs during repeated parking), the driver cannot precisely quantify the force with which the unlock button is pressed, so there are cases when the driver presses the unlock button too hard and shifts into reverse gear Danger of entering the park position by mistake

Embodiment Construction

[0023] according to figure 1 , according to the invention, the shifting device 1 for use in combination with an automatic transmission of a vehicle comprises a selector lever 2 , which here has a handle 3 . Furthermore, an unlocking button 4 is arranged on the selector lever 2 , which is integrated in the handle 3 in the present example. The selector lever 2 can be moved in the shift gate 5, which is in the figure 2 shown in simplified form. The shift gate 5 includes an automatic channel 6 as well as a manual channel 7 and a transverse channel 8 . To select gear 9 , selector lever 2 can be moved in automatic channel 6 and in manual channel 7 . The automatic channel 6 includes, for example, the following gears: Park P, Reverse R, Idle N and Forward D. In contrast to this, the manual channel 7 includes, for example, an intermediate position M, an upshift position + and a downshift position one. The transverse channel 8 is used to switch the selector lever 2 between the aut...

Abstract

The invention relates to a gear-shifting device for automatic transmission. A selection lever moves in an automatic channel for switching position selection, wherein includes a parking switching position, a astern running switching position, an idle speed switching position, and an advancing switching position. A locking mechanism is switchable between a locking condition and an unlocking condition, which prevents the selection lever from entering into the parking position and the astern running position or leaving from the astern running position in the locking condition, and allows the selection lever to move between each positions in the unlocking condition. The locking mechanism can further be switched to a partial locking condition, in which the selection lever is capable of entering into and leaving from the astern running position, but prevented from entering into or leaving from the parking position. The unlocking key includes a first operation position for transferring the locking device into the partial unlocking condition and a second operation position for transferring the locking device into the unlocking condition, so that convenience is enhanced.

Description

technical field [0001] The invention relates to a shifting device for an automatic transmission of a vehicle. Background technique [0002] From DE 100 57 299 A1 a shifting device for an automatic transmission of a vehicle is known, which has a selector lever which is movable in an automatic channel for selecting a gear. The automatic passage can have gears such as park, reverse, idle and forward, for example. The known shifting device also has a locking device, which can be switched at least between a locked state and an unlocked state. The shifting device also has an unlock button for changing the state of the locking device. In the locked state, the locking device prevents a movement of the selector lever into at least the park and reverse gears and at least out of the park gear. In the unlocked state, the locking device at least allows the selector lever to be moved between Park, Reverse, Idle and Drive. [0003] The known shifting device also has a manual channel in...
