Abstract
The invention relates to an actuation device for a shift-by-wire-actuated gearshift transmission. It includes a shifter base and an actuating element pivotally supported in a bearing location of the shifter base. The actuation device further includes at least one actuator for blocking the actuation element. Here, the actuator, in addition to its blocking function, is configured for generating mechanical vibrations or oscillations. A tactile feedback for the user of the actuation device with low design complexity is provided for flexible, tactile signaling of switching processes or locked actuation positions of a selection lever. Existing actuation devices can potentially be upgraded for tactile feedback purely by software-side changes.
Claims5
An actuating device for selecting shift steps of a shift-by-wire gear-changing transmission, the actuating device comprising
- a shifter base,
- a mechanical actuating element, which is rotatably or pivotally supported in a bearing of the shifter base, as well as at least one armature element which is moved back and forth by at least one actuator between an activated state, wherein the actuating element is blocked along at least one actuating direction through a stop on the armature element, and a deactivated state, wherein the actuating element is able to move along at least one actuating direction past the armature element,
- wherein the actuator is configured, in addition to its movement function for the armature element, to generate mechanical oscillations or vibrations.
