Abstract

PURPOSE:To realize compact constitution by arranging detection coils at a right position and a left position symmetrical to a guidance line. CONSTITUTION:A route sensor is composed by combining two detection coils consisting of a coil 3 crossing a guidance line 10 vertically and a horizontal coil 4 having a slanting angle theta to a road surface and parallel to the guidance line 10 in a horizontal plane, in a T shape. When a guided vehicle is on the guidance line 10, a voltage V4 is induced across the vertical coil 3, but a voltage V3 across the horizontal coil 4 is zero and the terminal voltages V1 and V2 of capacitors C3 and C4 are equal, so that the output of a differential amplifier OP is zero. When the vehicle deviates from the guidance line 10 to right and the coil 4 generates the voltage V3 in phase with the voltage V4 of the coil 3, the output voltage of the differential amplifier OP is positive and when to left, the output voltage is negative, thereby correcting its track through steering motor. Thus, the compact constitution is realized.
