The automotive transmission includes a controller configured to input a selection value based on a shift pattern selected from a plurality of shift patterns and operate a shift lever to move through a moving path based on the selected shift pattern when a shift intention is sensed. When the selection value is input, the shift position is set at an initial position based on the selected shift pattern and actuation power is generating according to the movement of the shift lever. The controller is configured to operate the moving path of the shift pattern based on the selected shift pattern and sense a position of the shift lever using a positing sensing unit. ## Claims ### Claim 1 An automotive transmission comprising: a controller configured to: input a selection value based on a shift pattern selected from a plurality of shift patterns, wherein the plurality of shift patterns include a reverse (R) stage, a neutral (N) stage, a drive (D) stage, and a null position; and operate a shift lever connected to the automotive transmission to move through a moving path based on the selected shift pattern in response to sensing a shift intention; operate the automotive transmission to actuate a particular gear according to the movement of the shift lever; operate the moving path of the shift lever based on the selected shift pattern; and sense a position of the shift lever using a position sensing unit, wherein when the selection value is input, the shift position is set at an initial position based on the selected shift pattern, wherein location of the null position is different based on the selected shift pattern, wherein the controller is further configured to operate the transmission to actuate the particular gear according to at least one profile, wherein power is applied to at least one direction of a reverse direction and a forward direction of the moving direction of the shift lever, and wherein the at least one profile includes a first profile in which power that is applied in the reverse direction along the moving path to select another shift position via at least one shift position from the current shift position gradually increases. ### Claim 2 (depends on 1) The automotive transmission of claim 1, wherein the controller is further configured to sense the shift intention using an approach sensor and a tactile sensor. ### Claim 3 (depends on 1) The automotive transmission of claim 1, wherein the controller is further configured to: output via a touch screen display device the plurality of shift patterns in a predetermined order, wherein the plurality of shift patterns are sequentially displayed in a movement direction from a contact point. ### Claim 4 (depends on 1) The automotive transmission of claim 1, wherein the controller is further configured to output at least one of the selected shift patterns and the shift position via a head up display (HUD) or a cluster. ### Claim 5 (depends on 1) The automotive transmission of claim 1, wherein the controller is further configured to block the shift lever from deviating from a predetermined range formed along the exterior side of the selected shift pattern and selectively block the selected shift pattern from moving to a particular shift position on the moving path. ### Claim 6 (depends on 1) The automotive transmission of claim 1, wherein the controller is further configured to operate the transmission to actuate the particular gear by a combination of power from multiple driving units. ### Claim 7 (depends on 1) The automotive transmission of claim 1 wherein the at least one profile further includes: a second profile in which power is applied in the reverse direction along the moving path up to a reference point of the moving path of the shift lever when a next shift position is selected, and power is applied in the forward direction along the moving path after the reference point; and a third profile in which power is applied in the reverse direction along the moving path to allow the shift lever to be restored to an original position after the shift lever moves from the current shift position and selecting of the other shift position is completed, wherein the movement in the reverse direction provides a resistive force to the shift lever. ### Claim 8 (depends on 7) The automotive transmission of claim 7, wherein in the second profile, the power applied in the reverse direction and the power applied in the forward direction gradually increase up to respective peak values and then gradually decrease. ### Claim 9 (depends on 1) The automotive transmission of claim 1, wherein in the first profile, the power applied when the shift lever moves from the previous shift position and then reaches the middle shift position and the power applied when the shift lever starts to move from the middle shift position to the next shift position are set to have different magnitudes. ### Claim 10 (depends on 7) The automotive transmission of claim 7, wherein in the third profile, the power applied in the reverse direction is continuously maintained until the shift lever is restored to the original position. ### Claim 11 (depends on 1) The automotive transmission of claim 1, wherein the controller is further configured to generate actuation power having a predetermined pattern that indicates an erroneous operation of the shift lever. ### Claim 12 (depends on 1) The automotive transmission of claim 1, wherein the position sensing unit includes a position sensor configured to sense the position according to movement of the shift lever. ### Claim 13 (depends on 2) The automotive transmission of claim 2, wherein the approach and tactile sensors are configured to sense power applied to the shift lever. ### Claim 14 (depends on 13) The automotive transmission of claim 13, wherein the tactile sensor is configured to sense at least one of a direction and an intensity of the power applied to the shift lever.
