Abstract: PURPOSE: An accelerator position sensor is provided to reduce the load of an electronic control unit(ECU) since sensor tolerance is decreased by programming with ASIC chip. CONSTITUTION: An accelerator position sensor comprises a transmission coil(101), a receiving coil(103), a coupler, and a signal processing unit. The transmission coil is connected to an oscillator to generate magnetic field. The receiving coil receives the magnetic field generated from the transmission coil. The receiving coil generates alternating frequency. The coupler is located between the transmission coil and the receiving coil. The coupler controls the magnetic field generated from the transmission coil. The signal processing unit is connected to the receiving coil. The signal processing unit calculates the rotation information of the coupler using the alternating frequency obtained from the receiving coil and outputs the displacement value of an accelerator pedal.
