APPARATUS FOR ELECTRONICALLY CONTROLLABLE TRANSMISSION

摘要

An apparatus for electronically controllable transmission is provided to shift gears by moving a shift lever and sensing the magnetic flux density of a magnet, which moves based on the rotation of the shift lever, using a three-dimensional (3D) hall sensor. The apparatus includes a shift lever having one end connected to a magnet and shifting gears by moving the shift lever and a shift lever body connected to the shift lever and allows the shift lever to move around shift axis or select axis. A sensor unit is mounted fixedly intersecting the shift axis and select axis within the shift lever body and senses the movement of the magnet around an X-axis, a Y-axis and a Z-axis as the magnet moves. The sensor unit is mounted at a tilted angle to provide at least two of three output signals with linearity.

主权项

1. An apparatus for electronically controllable transmission, comprising:
a shift lever configured to be manipulated using one of a first manipulation mode and a second manipulation mode; a magnet fixed to the shift lever; and a sensor unit fixedly installed to be separated from the magnet by a predetermined distance and, when the shift lever is manipulated, configured to sense a magnetic flux density of the magnet in the direction of each of an X-axis, a Y-axis perpendicular to the X-axis, and a Z-axis perpendicular to the X-axis and the Y-axis, wherein, in the first manipulation mode, the shift lever is pivoted on a first axis of rotation to select a gear on a first path, and, in the second manipulation mode, the shift lever is rotated about a second axis of rotation to select a gear on a second path different from the first path.
