Abstract
A transmission device for a vehicle includes a vehicle state detector for detecting a vehicle state, a transmission operation unit for enabling a transmission operation of selecting one of a plurality of transmission stages, and a position adjusting unit for adjusting a position of the transmission operation unit based on the detected vehicle state to allow the transmission operation unit to slidingly move between a first position where a transmission operation is disabled and a second position where a transmission operation is enabled.
Claims20
A transmission device for a vehicle, comprising:
- a transmission operation unit for enabling a transmission operation of selecting one of a plurality of transmission stages;
- a position adjusting unit for adjusting a position of the transmission operation unit to allow the transmission operation unit to slidingly move between a first position where the transmission operation is disabled and a second position where the transmission operation is enabled depending on whether the vehicle is in a first state or a second state, wherein the first state includes a state in which an engine of an internal combustion engine vehicle is not running or a state in which an electric vehicle is not drivable, and the second state includes a state in which the engine of the internal combustion engine vehicle is running or a state in which the electric vehicle is drivable;
- and
- a seating cover disposed between the transmission operation unit and the position adjusting unit for allowing the transmission operation unit to be seated thereon at the first position,
- wherein, while the transmission operation unit is moved from the first position to the second position, the transmission operation unit is subject to a combination of a translational motion and a rotational motion with respect to the seating cover.

A method of operating a transmission device of a vehicle, comprising:
- detecting whether the vehicle is in a first state or a second state, wherein the first state includes a state in which an engine of an internal combustion engine vehicle is not running or a state in which an electric vehicle is not drivable, and the second state includes a state in which the engine of the internal combustion engine vehicle is running or a state in which the electric vehicle is drivable;
- and
- slidingly moving a transmission operation unit between a first position, in which a transmission operation is disabled, and a second position, in which the transmission operation is enabled to allow selection of one of a plurality of transmission stages depending on whether the vehicle is in the first state or the second state,
- wherein, while the transmission operation unit is moved from the first position to the second position, the transmission operation unit is subject to a combination of a translational motion and a rotational motion with respect to a seating cover disposed under the transmission operation unit.

A transmission device for a vehicle, comprising:
- a transmission operation unit for enabling a transmission operation of selecting one of a plurality of transmission stages;
- a position adjusting unit for adjusting a position of the transmission operation unit to allow the transmission operation unit to slidingly move between a first position where the transmission operation is disabled and a second position where the transmission operation is enabled depending on whether the vehicle is in a first state or a second state, wherein the first state includes a state in which an engine of an internal combustion engine vehicle is not running or a state in which an electric vehicle is not drivable, and the second state includes a state in which the engine of the internal combustion engine vehicle is running or a state in which the electric vehicle is drivable;
- and
- a transmission unit coupled to the transmission operation unit for enabling the transmission operation via the transmission operation unit, the transmission unit being configured to be moved between the first position and the second position by the position adjusting unit,
- wherein the position adjusting unit comprises:
- a driving unit for generating a driving force for adjusting the position of the transmission operation unit;
- and
- a guide unit for guiding the position of the transmission operation unit to allow the position of the transmission operation unit to be adjusted due to the driving force of the driving unit,
- wherein the guide unit comprises:
- a lead screw configured to be rotated about a rotation axis by the driving force of the driving unit;
- and
- a nut member configured to be moved along a direction of the rotation axis of the lead screw due to a rotation of the lead screw, and
- wherein the nut member includes a guide groove, into which a guide protrusion formed on the transmission unit is inserted to allow the transmission unit to slidingly move as the lead screw is rotated.
