Abstract
The present disclosure discloses a sensing system for sensing a position of a gear shaft. In the present disclosure, a magnet apparatus is provided on the gear shaft, where the magnet apparatus includes, along a rectilinear motion direction, a first length region magnet and a second length region magnet, the second length region magnet including a first portion and a second portion, a magnetic field of the second portion of the second length region magnet corresponding to a reverse gear position being different from that of the first length region magnet and that of the first portion of the second length region magnet. An actually induced electrical signal generated by sensing the motion of the magnet apparatus is different from a reference inductive electrical signal of a corresponding position of a reference magnet. The processing unit compares the inductive electrical signal generated by sensing the motion of the magnet apparatus against a simulated inductive electrical signal and determines whether the gear shaft is at a reverse gear position or a forward gear position based on a difference from the comparison.
