Abstract
The present disclosure discloses a sensing system for sensing a position of a gear shaft. The present disclosure may implement determination of whether the gear shaft is at a reverse gear position, a forward gear position or a neutral gear position by: partitioning a magnet into a first length region magnet and a second length region magnet, wherein the first length region magnet and the second length region magnet have different magnetic field directions, sensing and generating an inductive electrical signal reflecting motions of the first length region magnet and the second length region magnet; storing, by a memory unit, a first type reference signal for the first length region magnet and a second type reference signal for the second length region magnet, which are sensed by simulation; and comparing, by a processing unit, the inductive electric signal against the first type reference signal and the second type reference signal, which reflect different gear positions, respectively. By arranging only one magnet and one set of circuitry mechanical elements to sense a position of the gear shaft, the sensing apparatus according to the present disclosure effectively implements detect…
