Each actuator does not operate because the electromagnetic switch is open. Next, when the position selector switch is in the neutral state, current flows through the excitation coil, which closes the electromagnetic open/close switch, which becomes a self-lock state, so even if the position selector switch leaves the neutral state, Each actuator maintains its operating state. Furthermore, by switching the manual switch to automatic control, the conventional manual driving can be switched to automatic driving.

An example of an electronically controlled automatic transmission with three forward and forward speeds is shown below. In the figure, circuit 1 is a power supply circuit connected to the vehicle battery circuit, and circuit 3 is an automatic power supply circuit connected to the main automatic cruise control system power supply circuit.
The tomatic control circuit, circuit 4, is a manual operation circuit leading to the emergency manual travel unit power supply. 2
is a manual switch and an automatic/
This is to manually switch the power supply for each device, and during normal driving, circuits 1 and 3 are connected. A position selector switch 7 has a switch 13 for selecting the position of each actuator and an operation switch 12 for detecting neutral.
The switches 12 and 13 are interlocked, and the circuit 1
1 communicates with the actuator that creates each running state. Further, 15 is an electromagnetic open/close switch, 14 is an excitation coil that closes the switch 15, and 16 is an electromagnetic switch.

せることが可能となる。 When the operation switch 12 of the position selector switch 7 is not in the neutral (N) position (the switch 13 is also not in the neutral (N) position), the driver operates the manual switch 2 to select circuits 1 and 4.
Even though the relay 16 is open, the manual operation circuit 4 and the circuit 10 are not electrically connected, and each actuator does not operate. The above-mentioned neutral state is caused by the driver's operation, and when the operating switch 12 of the position selector switch 7 is in the neutral (N) state (the switch 13 is also in the neutral (N) state), The circuit 5, the operation switch 12, and the circuit 8 become conductive, and current flows through the excitation coil 14, causing the excitation open/close switch 15.
is closed, manual operation circuit 4 and circuit 10 are electrically connected,
It becomes possible to operate each actuator via the switch 13.

->Circuit 8 -> Conductive with excitation coil 14. Then, the electromagnetic switch 15 is closed. This switch 1
When 5 is closed, passage 9 is also conductive, so
Even when switch 12 is moved to the N position, coil 14 continues to be energized by circuit 9. In addition, when the driver operates the manual switch 2 for automatic driving and connects the power supply circuit 1 and the automatic control circuit 3, the circuit 1 and the manual operation circuit 4 are connected.
Since the current is cut off, current no longer flows through the excitation coil 14, the excitation switch 15 is opened, and the manual operation circuit 4 and the circuit 10 are brought into a non-conducting state. By the above-mentioned action, manual running is switched to automatic running.
