PURPOSE:To enable smooth running control, by correcting the effect of inductive interference due to harmful magnetic substance, based on the induced magnetic field from the self-energizing induction line mounted on an automatic running car. CONSTITUTION:BPFs6, 8 filter the signal having the frequency of current flowing to the induction line installed on the floor, and BPFs7, 9 filter the signal having the frequency different from the current above, but the frequency of the current flowing to the self-introduced line of running car. Further, the signal caused at pickup coils 3, 4 mounted with a pair left and right at the bottom of running car due to the induced magnetic field on the induced line, passes through BPFs6, 8 and is deviated at the summing point 14, rectified 10 and output to the post stage as a steering signal via the summing point as DC signal. On the other hand, the signal produced to coils 3, 4 from the induced magnetic field on the induction line of car, passes through BPFs7, 9, and it is summed 15 and rectified 11, amplified 13 and fed to the summing point 16. Thus, the effect of induced interference due to harmful magnetic substance is corrected, allowing smooth running control. |
