中文摘要 | 摘 要 多年前所獲之新型103898專利:自動輔助方向燈(參看圖4),由於低車速時反應不 良,今以二個水銀開關如(圖1)置於汽車方向盤左右,轉向時可立即反應,故名自動方 向燈,將二個水銀開關如(圖1)置於汽車方向盤左右,以此感知器產生的訊號,如此便可 將駕駛者意圖,第一時間顯示於方向燈。當然須經微分,清除,栓鎖,禁能,延遲, 閘控震盪處理如(圖3 )產生汽車自動方向燈的功能。 微分:將L,R 二水銀開關,恰當的偏壓,只讀取6伏到0伏,下降緣的微分訊號,當觸 發訊號。 理由:微分為RC 串接,唯當變化時才可能觸發。 清除:如(圖3)當直行時因水銀開關以10度斜角固定於左右, 水銀開關處於不動作之穩 態,以此當清除訊號,使方向燈不動作,G9腳10低電位,D7,D8導通是謂清 除,理由甚明。 栓鎖:如(圖2)一旦L,R 二水銀開關任一動作(導通) ,要使邏輯栓鎖住目前的動作, 2反相器串可視為一位元記憶體,左轉栓鎖由G1,G2完成。 禁能:當任一方向燈動作時,應同時禁止另一方向燈讀取動作,由D3,D4完成。 理由:輸出為低阻抗,當左轉時二極體(D11)先導通,同時清除失效 ,因二極體D7, D8截止,此時容許訊號讀取,左轉訊號先拴鎖於一位元記憶體(G1,G2),二極 體(D4)將右轉輸入端嵌位於高位低阻抗,禁止右轉訊號讀取。 延遲:是指啟動時或任一方向燈動作,需將此動作延遲1秒,亦即產生重複觸發之1秒 單擊波(retriggerable one-shot)當致能(enable)訊號。 理由:讓方向燈的動作像我們習慣認知之方向燈該有動作,左轉由D5,R5 ,C3組 成。 閘控震盪:是指以致能訊號驅動無穩多諧震盪以產生警告方向燈效果,由G7,R11, C5組成。 唯一混亂狀態之可接受性:假設逆時恰為360度,產生清除,如續順時轉,是顯示右轉 燈。(此唯一混亂狀態之可接受性是機率很小,況且逆時為360度時,顯示左轉或右轉燈意 義已不大(車身已與路面垂直)。(參看圖2左轉時只有E,右轉時只有G 為混亂狀態) 。 |
英文摘要 | ABSTRACT I got auto-aid turning lamp patent years ago ( patent no.103898 see fig4),owing to bad response at low car speed, the up coming revise do work right. By fixing two mercury switches apart on both left and right side of the car steeling wheel ,when turning to right or left, we can get the intention of the driver in no time and drive the turning lamps to reveal right signal. Of course we need digital signal processing such as differential, clear, latch, forbidden, delay and gated oscillation to derive right function of auto turning lamp for car as shown in (fig.3). Differential CKT:We try to get the falling edge differential signal as to trigger the following latch circuit. The reason is Differential CKT ,being a kind of R, C in series, it can only be triggered by input changing . Clear: as shown in (fig.3) The auto-turnning lamp inactive when We drive straight ahead for 2 mercury switches were fixed on left and right side of the steeling wheel by 10 degree angle.The 2 mercury switches were inactive, stable state at this time. It only happens when NAND gate G9 pin10 active (low level ) and diode D7,D8 on and clear the content of the latch . Latch: the first triggered signal was to be latched until clear .As we know 2 invertors In series forms a standard 1 bit latch, so the left turn latch done by G1,G2 in series. forbidden: when one of the turning lamps acts we need to let another stop action.( forbid to read data), D3,D4 can do it. The reason is: The output is of low impedance. When left turn occurs ,the diode (D11) ON first, the clear lost its function meanwhile ,for the diodes(D7,D8) are off . And at that time allowing inputs to read , so thus the left turn signal will be latched in one bit memory (G1,G2), and the diode (D4) is active to clamp right turn input at high voltage low impedance so as to forbid further inputs reading at right turn site. Delay: When power on or anyone of the turning lamps acts ,need to delay such action by 1 second after clear signal set in by using retriggerable one shot technology .make the job being done by D5,R5,C3 .And the reason is to make the lamp flashing as what we might think it should be. Gated oscillation: By using latch signal as the control signal to control oscillation , thus drive the turning lamps ,and it’s being done by a NAND gate G7,C5 and R11. The only one state that might confuse is acceptable: it might happen when left turn for 360 degree and then follow a right turn .the turning lamp would reveal right turn warming signal. For in such kind of scenario the car body already perpendicular to the road.(it’s no difference to show right turning lamp or the left turning lamp .see fig.2 the confusion only happened on E when left turn and only happened on G when right turn) |
