Abstract:
An automatic shift control device for an electronic pneumatic shift system which detects a position of a gearshift lever through a lever position sensor, the lever position sensor outputting signals corresponding to the position of the gearshift lever to an electronic control unit such that the electronic control unit controls a magnetic valve assembly to supply and exhaust air to the shift control device to thereby control a transmission, the shift control device comprising:a magnet disposed on one end a shift rod of the shift control device; anda linear variable distance transducer provided on an end of the shift control device corresponding to a position of the magnet, the linear variable distance transducer detecting a change in a magnetic field caused by a movement of the shift rod, and the linear variable distance transducer outputting signals corresponding to the change in the magnetic field to the electronic control unit.
