Abstract:
A gear position sensor system for an automobile transmission having a shift lever, a rod slidably and rotatably moved according to a movement of said shift lever for selecting a gear position and a transmission housing, comprising:magnetism generating means for generating magnetism; detecting means for detecting said magnetism and having a plurality of elements to detect said magnetism per each element, said magnetism generating means and said detecting means being fixed on one of said rod and said transmission housing; shielding means fixed on the other of said rod and said transmission housing and provided between said magnetism generating means and said detecting means for selectively allowing said magnetism to pass through to each of said elements so as to form a combination of magnetism detecting condition for said detecting means corresponding to a selected shift position, said combination being predetermined per each shift position; and judging means for judging a selected gear position based on said combination.
