ていることになる。Next, I will explain the entire @work with the above configuration. Assume that the vehicle is currently operating in the automatic operation mode, and the deviation 1ΔE1 gradually increases to exceed the upper threshold value S1 of the comparator 94. Then, the relay stem points 97 and 98 are closed, and the deviation output -ΔE is manually input to the dynamic setting device 70. Further, in this mode, the deviation output -ΔE is manually set by the manual voltage K14 rectifier 80. - The manual electric setting device 70 operates according to the human power of ΔE, and changes the set voltage i9F. As a result of the above, the level of the control signal EM changes so that the manual side control signal EM becomes almost equal to the automatic side control signal EA (so that the deviation 1ΔE1 is smaller than the lower threshold S2 of the comparator 94). do. At the same time, the set voltage SF on the manual side is adjusted to be almost equal to the set voltage SV on the automatic side.

切換えても、前述したショックは発生しない。When EM=8 people are controlled as described above, relay contacts 97 and 98 are opened. Even if the operating mode is switched at this time, the shock described above does not occur.
手動運転モードにてリレー接点97 、98が閉じると

しくなるように、自動側の8人、Svがル湖整さnる。When the relay contacts 97 and 98 are closed in the manual operation mode, the 8 persons and Sv on the automatic side are adjusted to be approximately equal to the EM and SF on the manual side in the same manner as described above.
その結果EAζEMになれば、自動運転モードに切換え
てもショックは発生しない。If the result is EAζEM, no shock will occur even when switching to automatic driving mode.
