Abstract

Provided is an apparatus for electronically controllable transmission, and more particularly, an apparatus for electronically controllable transmission, the apparatus capable of shifting gears by moving a shift lever and sensing the magnetic flux density of a magnet, which moves in accordance with the rotation of the shift lever, by using a three-dimensional (3D) hall sensor. The apparatus includes: a shift lever including one end which is connected to a magnet and shifting gears by moving the shift lever; a shift lever body which is connected to the shift lever and is allowing the shift lever to move around shift axis or select axis; and a sensor unit including a 3D sensor which is mounted fixedly in the place intersecting the shift axis and select axis within the shift lever body and can sense the movement of the magnet around an X-axis, a Y-axis and a Z-axis as the magnet moves, wherein the 3D sensor is mounted at a tilted angle for providing at least two of three output signals with linearity.

Claims

1-13. -13. (canceled)

14. An apparatus for an electronically controlled transmission, the apparatus comprising:

a gear shift lever;

a magnet connected to the gear shift lever; and

a single three-dimensional hall sensor fixedly mounted in a location adjacent the gear shift lever and configured to detect gear positions of the gear shift lever by providing an indication of a position of the magnet in each of an X-axis, a Y-axis perpendicular to the X-axis, and a vertical Z-axis perpendicular to both the X-axis and the Y-axis.

15. The apparatus of claim 14, wherein the gear positions comprise automatic gear positions of the gear shift lever and manual gear positions of the gear shift lever.

16. The apparatus of claim 14, wherein the gear shift lever is configured to rotate about a pivot point.

17. The apparatus of claim 16, wherein the rotation of the gear shift lever about the pivot point displaces the magnet in a vertical direction relative to the location of the three-dimensional hall sensor.

18. The apparatus of claim 16, wherein the rotation of the gear shift lever about the pivot point displaces the magnet into a position where a surface of the magnet is disposed at an angle relative to a surface of the three-dimensional hall sensor.

19. The apparatus of claim 18, wherein the three-dimensional hall sensor is configured to sense the angle at which the surface of the magnet is disposed relative to the surface of the three-dimensional hall sensor.

20. The apparatus of claim 19, wherein the angle is correlated with a gear position of the gear shift lever.

21. The apparatus of claim 14, wherein the three-dimensional hall sensor is configured to detect the position of the magnet without maintaining a constant gap between the three-dimensional hall sensor and the magnet.
