The control system comprises a metal track (10) having a good electromagnetic coupling coefficient, a pair of pickup coils (20, 20A) tracking the track, a pair of soft oscillators (30,30A) varying the oscillating intensity according to the coupling coefficient generated on approaching to the track with the pickup coil, a pair of frequency detectors (40,40A) filtering the preset frequency from the output of the soft oscillator, a pair of amplifiers (50,50A) and A/D converters (60,60A), and a microprocessor (70). The microprocessor controls the vehicle so as to keep the voltages provided from the pickups constant so that the vehicle follows the track correctly.
