    摘要: An apparatus for detecting a vehicle seat position is disclosed. The apparatus includes a hall sensor for detecting a target position according to a flux variation; a first power-supply unit for activating the hall sensor in an active period of a received drive-voltage pulse; and a second power-supply unit for providing an auxiliary power-supply signal to activate the hall sensor in an inactive period of the drive-voltage pulse. Therefore, the apparatus can effectively address two-pin hall sensor's problems caused by hysteresis characteristics.
