Abstract

PURPOSE:To supply the electric source to the controller in stable and permit various kinds of control effected by the controller by a method wherein the supply of the electric source to the controller by means of a key switch is effected through a simple relay circuit. CONSTITUTION:When the ACC key switch SW1 is opened and the circuit is transferred into a condition that the electric source cannot be supplied, the supplying path of the electric source E through the diode D of a relay L1 is intercepted, however, the relay L1 is held through the contact 11 of itself and the contact 12 of the relay L2, therefore, the supply of the electric source to the controller CNT may be continued.

Therefore, operations are performed in the above order or in the reverse order. For example, preheating and starting are performed at the H and ST positions after passing through the ACC and ON positions, and the ST

On the other hand, as for the terminals, as shown in the figure, there are terminals R, , l which connect to the preheating plug, terminal B which connects to the power source, terminal ACC which connects to the radio and wiper, terminal ON which connects to various devices, terminal ST which connects to the starter motor. There is a connection relationship as shown by circles and lines corresponding to the operating position of the key switch. For example, in the OFF position, the key switch is connected to terminal B only, in the ON position, it is connected to terminals B, ACC, and ON, and in the ST position, the key switch is connected to terminal B.

As is clear from these relationships, the key switch for diesel cars is different from that for gasoline cars; in the I (, ST) positions, it is connected to a dedicated terminal, and other devices such as ACC and ON are connected. It does not have a terminal that can be used for connection with the

There are positions or terminals such as ON that can supply power to other devices, and positions or terminals such as I-I and ST that cannot supply power to other devices. Therefore, even if you try to drive a controller that performs various control operations in conjunction with this key switch, it may be difficult to supply power to it, so there is a drawback that the controller cannot be operated in conjunction with the key switch. had. That is, since the controller also controls the engine, it does not matter when the key switch is in the 01"T' position, but in any other position it is always in the 11! position.
It is extremely inconvenient that power may not be supplied depending on the position of the key switch, even though power must be supplied.

The present invention has been made to eliminate these drawbacks, and its purpose is to constantly supply stable power to the controller without modifying the key switch as described above.

The feature is that as long as the key switch position is in a position where power can be supplied to the controller, power will be continuously supplied to the controller, and the key switch position will not be in a position where power can be supplied to the controller. When the controller is moved to a certain position, power is supplied to the controller continuously for a predetermined period of time from that point on, so that it is always stable, at least as long as normal driving operations are performed! The point is that it is possible to supply a source.

Both SW3 are off (open), and when switch SW1 is off (open), switch SW2. When both SW3 are turned on (closed), the controller CNT is configured to receive the operating state of such switches via the terminal T and perform a predetermined control operation.

Now, when ACC switch 8W1 is closed, relay L
1 is supplied with power E through diode D, the relay L1 operates, and the contact t1 starts supplying power to the controller CNT. In other words, switch 8
Controller CNT is activated by closing W1 or by key switch.
This state continues as long as the ACC switch SWI is closed. Next, when the ACC switch SW1 is opened, that is, when the key switch moves from a state where power can be supplied to the controller to a state where it cannot be supplied, the supply path of the power E via the diode D of the relay L1 is cut off, but the relay L1 is its own contact t1 and relay L
Since the power is maintained through the second contact (break contact) t2, the power supply to the controller CNT is continued. At this time, the one-shot multi MM1 detects that the switch SW1 is open, outputs a 1' signal, and turns off the normally operating transistor TRI. It operates for a predetermined time (11 seconds). Next, the one-shot multi-MM2 operates at the falling edge of the one-shot multi-MMI and outputs an output for a predetermined time (T2). This allows transistor TF! , 2 are activated, relay L2 is energized and its contact 12 is opened.

By the way, the capacitor C is provided to ensure the above-mentioned time T2. Therefore, when relay L2 is operating as shown in Fig. 3 (c), switch S as shown in Fig. 3 (8)
If WI is closed, power is supplied to the controller as shown in the figure (Q) (continued), but if switch SW1 is not closed, the power is turned off as shown in the figure (dotted line in Q). This will result in the following. Tsume υ, ACC switch S
If no operation is performed to close the WI 11 seconds after it is opened, it is assumed that the key switch is in the OFF position, and the power to the controller CN T is cut off.
