Abstract

An activation apparatus for a transmission of a motor vehicle includes a gear selector that is configured to move in a shift gate to thereby select first drive programs, and an activation device that is connected to the gear selector. Actuation of only the gear selector activates the first drive programs. The first drive programs include a forward drive program and a reverse drive program. The gear selector is configured take up a monostable rest position in the shift gate. Simultaneous actuation of both the gear selector and the activation device activates a second drive program that is different from the first drive programs. The activation device is a spring-loaded switch that is activated by actuating the gear selector.

First claim

What is claimed is:

1. An activation apparatus for a transmission of a motor vehicle, comprising:
a gear selector that is configured to move in a shift gate to thereby select first drive programs; and
an activation device that is provided on the gear selector, wherein
actuation of the gear selector activates the first drive programs, the first drive programs including a forward drive program and a reverse drive program,
the gear selector is configured take up a monostable rest position in the shift gate,
simultaneous actuation of both the gear selector and the activation device along two different directions activates a second drive program that is different from the first drive programs,
the activation device is a spring-loaded switch that is activated by actuating the gear selector,
the second drive program is a sport mode of the motor vehicle, and
the simultaneous actuation of both the gear selector and the activation device if affected by applying a compressive force to the gear selector, while pressing down on the gear selector to activate an electrical switch, the electrical switch actuating the activation device.

2. The activation apparatus according to claim 1 , wherein the gear selector is movable into a first engaged position by a swivel movement in one direction and is movable into a second engaged position by a further swivel movement in the same direction.

3. The activation apparatus according to claim 2 , wherein the gear selector is configured to select the reverse drive position by swiveling the gear selector from the rest position into a third engaged position when a parking lock is activated.

4. The activation apparatus according to claim 1 , further comprising:
a parking lock activation device arranged on or adjacent to the gear selector, the parking lock activation device being configured to activate and/or deactivate a parking lock.

5. The activation apparatus according to claim 4 , wherein the gear selector is configured to select the forward drive program by a swivel movement of the gear selector from the rest position into a first engaged position when the parking lock is activated, and to select the further drive program by activating the activation device and swiveling the gear selector into the first engaged position.

6. The activation apparatus according to claim 1 , wherein, when the reverse drive position is selected, the gear selector is configured to select a neutral position by swiveling the gear selector from the rest position into a first engaged position, and to select the forward drive program by swiveling the gear selector into a second engaged position.

7. The activation apparatus according to claim 6 , wherein, when the forward program is selected, the gear selector is configured to select a neutral position by swiveling the gear selector from the rest position into a third engaged position, and to select the reverse drive position by swiveling the gear selector into a fourth engaged position.

8. The activation apparatus according to claim 1 , wherein the gear selector comprises a detent pin arranged at a lower end thereof, the detent pin being prestressed via a spring; and wherein the detent pin is engagable in a rest detent position in the monostable rest position of the gear selector and, via swiveling of the gear selector, the detent pin is engagable in at least one further detent position.
