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. |
