随着科技不斷進步，各種先進的輔助監測和智能化系統在汽車上開始普及，極大的提高了汽車駕駛安全性和舒适性。利用紅外成像技術輔助駕駛員在黑夜中看清道路、行人和障礙物等，減少事故發生，增強主動安全性的夜視輔助系統就是一種幫助駕駛員提高夜間行車安全的駕駛輔助系統。
這次要拆的是AutoLiv（奧托拉夫，一家非常有名的汽車安全系統解決方案提供商）為奧迪生産的二代夜視系統的電腦子產品，配合他家的夜視（熱成像）攝像頭使用。它可以偵測出車前的行人，通過儀表盤上的顯示屏顯示熱成像的圖像和對行人行進高亮處理。
它的外殼使用外鋁合金材質，可以很好的屏蔽輻射，不過内部并沒有防水設計，防水需要在外部再扣一個塑膠盒。
拆開外殼可以直接取下主機闆，主機闆左右各一顆TI的DSP晶片，TMS320DM642。中間有一顆XILINX的XA3S500E汽車級FPGA。
背面有一顆飛思卡爾的MC9S12XDT512，16位的單片機。
DSP晶片體積比較大
FPGA周邊有2顆DDR RAM和一顆FLASH晶片
在另一顆DSP旁邊是有一顆ADI的ADV7179，RGB轉CVBS晶片，通過一顆TI的LMH6643和右上角的雙路FDW2501N雙通道的N溝道MOSFET将資料轉換成差分信号輸出
DS90C124是一顆LVDS解串器，用來将夜視相機通過2線發送來的LVDS信号轉換成TTL信号,通過FPGA采集資料後送到DSP做進一步的圖像處理
LM2904 是一顆 1A、26V、高 PSRR、低壓降穩壓器
右上角的TPS5430 是一顆5.5V 至 36V 輸入 3A 500kHz 降壓轉換器
左下解的TPS54310PWPR 是一顆輸入電壓為 3V 至 6V 的 3A 同步降壓轉換器
闆子上一共有2顆絲印為625033的沒找到具體型号，可以肯定是CAN收發器，其中一路與夜視相機通信，另一路與汽車的其它總線通信
下邊是一顆英飛淩的ITS428L2，帶有內建垂直功率FET的高端電源開關，提供嵌入式保護和診斷功能。
IDT74FCT3807是一顆時鐘驅動器，左邊有2顆晶振
與相機連接配接的使用HSD 4P接口
内部有2顆日本ELNA的電解電容
附上一段夜視電腦和夜視相機通信的資料，因為夜視電腦内儲存的ID與相機不比對，是以它們經過一段艱難的對話（附注釋）後就進入了重複的一問一答模式。

以前夜視電腦還會向相機要随機數，後來發現相機多次給的都不對就進入了自我保護模式。
