Explanation of the circuit operation Operation at the time of the car start By making the key to the accessories position, the current flows through D3 and RL3 operates. RL5 and also RL7 operate through D5 and also D7 by the operation of RL3. At this time as for the point of contact inside the mirror, C is off and O is on. The current flows with rl5-1 M O rl5-2 by the operation of RL5 and the mirror opens by motor. O becomes off that the mirror finishes opening and motor suspends. The left mirror opens by the operation of RL7 similarly. It is this condition during drving the car. Operation in the time that drew out the key When the key is drawn out the power supply of the accessories circuit is cut. However, the current flows through point of contact rl3-1 of oneself and rl2-1 then RL3 continues to operate. D2 be the diode for inverse current prevention. Operation in the time that closed the door for descending from the car When the door of the driver's seat is opened after the key is drawn out, door SW closes and RL1 operates. The power supply to capacitor of C1 is cut by the operation of RL1 and the electricity of C1 discharges through R1. When the door is closed door SW becomes off and RL1 releases( does not operate ). Because rl1-1 closes when RL1 releases the current flows to C1 a moment. The current that flows to C1 is amplified with TR1 and RL2 operates a moment. Through the means that RL2 operates a moment the current of RL3 is cut and RL3 releases and rl3-1 becomes off. The operation of RL2 ends right away and rl2-1 becomes on once again. However, RL3 does not do the operation, because the point of contact of oneself became off. By release of RL3, RL5 and also RL7 that were operating through rl3-2 release. The current flows with rl5-1 M C rl5-2 by the release of RL5 and the mirror closes by motor. C becomes off that the mirror finishes closing and motor suspends. The left mirror closes by the release of RL7 similarly. All the relays are releasing in this condition and the battery does not consume. ( Although the current flows to R1, R2 and R3 in this condition, but there is not a problem because it is the current of a 0.4mA rate. ) Operation of door mirror control SW The ordinariness does the above kind of operation, by make the AUTO position. When the OPEN position is made RL5 or RL7 operates forcibly and the mirror opens. When the CLOSE position is made RL5 or RL7 releases forcibly and the mirror closes. As for the recent car, the door mirror is popular thing and the electromotion housing type is used usually. Even my car is a door mirror type, but the electromotion housing function was not attached. Although it does not become obstructive even if it does not close the door mirror, there is the case that the person is not able to pass when it does not close the mirror in narrow parking place etc. Although the mirror on the side of the driver's seat is closed easily with the hand, it assumed to go to the opposite side of the driver's seat to close the mirror on the side of the assistant seat. I who dislike bothersome would change the door mirror into an electromotion housing type. Because it is not interesting even if it attaches it as it is, the work like the following tried to be done. When the engine of the car is started door mirror opens automatically. It closes automatically when the key of the car is removed. It could the work to here well. However, trying to use it and I understood that it is dissatisfying with only the condition of the top. There is a problem when the car is stopped, although it has no problem when the car is started. Usually, I draw out the key to stop the engine and open the door and appear outside. When the door is opened I confirm whether the car is not coming from the back with the door mirror. The door mirror has closed when the key is drawn out. Then I have come to turn around the back to confirm the car that comes from the back without the door mirror. It is bothersome for me, although it is reliable. Thereupon, the following condition was added. Mirror does not close right away even if the key is drawn out. Mirro does close when the door of the driver's seat has been closed once again after opening. The trouble of the housing of the door mirror was gone with this. And also the switch of mirror opening and closing is attached in the driver's seat.
