Abstract

An actuating device for shifting stages of a transmission, wherein a displaceable actuator for the manual selection of a shift stage (or driving mode) is provided, which can be adjusted into a plurality of positions. At least some or each of the positions can be assigned necessary conditions for the engagement of a shift stage assigned to the position. If the actuator is displaced into a position for which the conditions necessary for the same are not fulfilled, the associated shift stage is not engaged in the transmission and corresponding first signaling is carried out. Fulfillment of the necessary conditions of the associated shift stage following the displacement of the actuator into the position assigned to the shift stage or following the displacement in the direction of the associated position for the associated shift stage leads to the shift stage in the transmission being engaged.

First claim

What is claimed is:

1. An actuating device for shifting shift stages of a transmission or engaging a driving mode of a transmission of a motor vehicle, wherein a displaceable actuating means for the manual selection of a shift stage or driving mode is provided, which can be adjusted into a plurality of positions, wherein at least some or each of the positions are assigned necessary conditions for the engagement of the shift stage or driving mode assigned to the position,
wherein, when the actuating means is displaced into a position or in the direction of a position for which the conditions necessary for the same are not fulfilled, the associated shift stage or driving mode is not engaged in the transmission and a corresponding first signaling is carried out,
wherein the fulfillment of the necessary conditions of the associated shift stage or driving mode following the displacement of the actuating means into the position assigned to the shift stage or driving mode or following the displacement in the direction of the associated position for the associated shift stage or driving mode leads to the shift stage or driving mode in the transmission being engaged,
wherein the signaling that the necessary conditions are not present or that an engagement of a shift stage or driving mode is not engaged is carried out by a first signaling including one or more of acoustic, optical and haptic signals, and
wherein fulfillment of the necessary conditions of the associated shift stage or driving mode following the displacement of the actuating means into the position assigned to the shift stage or driving mode or following the displacement in the direction of the associated position for the associated shift stage or driving mode leads to a second signaling including one or more of acoustic, optical and haptic signals being carried out.

2. The actuating device as claimed in claim 1 , wherein the haptic first signaling and the haptic second signaling are carried out by vibration of the actuating means.

3. The actuating device as claimed in claim 2 , further comprising a vibration actuator that is configured to act on the actuating means.

4. The actuating device as claimed in claim 1 , wherein when the actuating means is displaced into the position or in the direction of the position in relation to which the conditions necessary for the same are not fulfilled, the actuating device generates or outputs a signal which blocks engagement of the associated shift stage or driving mode.

5. The actuating device as claimed in claim 1 , wherein when the actuating means is displaced into the position or in the direction of the position in relation to which the necessary conditions of the associated shift stage or driving mode are only fulfilled following the displacement of the actuating means into the position assigned to the shift stage or driving mode or following the displacement in the direction of the associated position for the associated shift stage or driving mode, the actuating device generates or outputs a signal which permits or initiates the engagement of the associated shift stage or driving mode.

6. A method for operating a transmission having an actuating device for shifting shift stages of a transmission or for engaging a driving mode of a transmission of a motor vehicle, and a displaceable actuating means for manual selection of a shift stage or driving mode and which can be adjusted into a plurality of positions, wherein at least some or each of the positions can be assigned necessary conditions for the engagement of the shift stage or driving mode assigned to the position, wherein the method comprises:
when the actuating means is displaced into a position or in the direction of a position for which the conditions necessary for the same are not fulfilled, (i) the associated shift stage or driving mode is not engaged in the transmission, and (ii) corresponding first signaling including one or more of acoustic, optical and haptic signals is carried out, and
fulfillment of the necessary conditions of the associated shift stage or driving mode following the displacement of the actuating means into the position assigned to the shift stage or driving mode or following the displacement in the direction of the associated position for the associated shift stage or driving mode leads to (i) the shift stage or driving mode in the transmission being engaged, and (ii) a second signaling including one or more of acoustic, optical and haptic signals being carried out.

7. The method as claimed in claim 6 , wherein when the actuating means is displaced into the position or in the direction of the position in relation to which the conditions necessary for the same are not fulfilled, the actuating device generates or outputs a signal which blocks engagement of the associated shift stage or driving mode in the transmission.

8. The method as claimed in claim 6 , wherein when the actuating means is displaced into the position or in the direction of the position in relation to which the necessary conditions of the associated shift stage or driving mode are only fulfilled following the displacement of the actuating means into the position assigned to the shift stage or driving mode or following the displacement in the direction of the associated position for the associated shift stage or driving mode, the actuating device generates or outputs a signal which permits or initiates the engagement of the associated shift stage or driving mode in the transmission.
