GEAR-SHIFT SYSTEM FOR AUTOMATIC TRANSMISSON OF VEHICLE USING INDUCTIVE DISPLACEMENT SENSOR AND SIGNAL PROCESSING METHOD OF THE SAME

摘要

PURPOSE: A gear-shift system for automatic transmission of vehicle using inductive displacement sensor and signal processing method of the same is provided to improve durability. CONSTITUTION: The excitation coil is installed in substrate. The excitation coil is wound according to the fixed orbit the plurality of times. The excitation coil is connected to the oscillator(22). Coupler is installed in the regular interval from the excitation coil. The coupler(50) is formed into the shape shielding a part of the excitation coil. Gearshift is connected to coupler. Receive coils(30,40) are installed between coupler and excitation coil. The signal processor is connected to a pair of receive coils. The shift control unit(2) changes the signal corresponding to shiftgear.
