随着科技不断进步，各种先进的辅助监测和智能化系统在汽车上开始普及，极大的提高了汽车驾驶安全性和舒适性。利用红外成像技术辅助驾驶员在黑夜中看清道路、行人和障碍物等，减少事故发生，增强主动安全性的夜视辅助系统就是一种帮助驾驶员提高夜间行车安全的驾驶辅助系统。
这次要拆的是AutoLiv（奥托拉夫，一家非常有名的汽车安全系统解决方案提供商）为奥迪生产的二代夜视系统的电脑模块，配合他家的夜视（热成像）摄像头使用。它可以侦测出车前的行人，通过仪表盘上的显示屏显示热成像的图像和对行人行进高亮处理。
它的外壳使用外铝合金材质，可以很好的屏蔽辐射，不过内部并没有防水设计，防水需要在外部再扣一个塑料盒。
拆开外壳可以直接取下主板，主板左右各一颗TI的DSP芯片，TMS320DM642。中间有一颗XILINX的XA3S500E汽车级FPGA。
背面有一颗飞思卡尔的MC9S12XDT512，16位的单片机。
DSP芯片体积比较大
FPGA周边有2颗DDR RAM和一颗FLASH芯片
在另一颗DSP旁边是有一颗ADI的ADV7179，RGB转CVBS芯片，通过一颗TI的LMH6643和右上角的双路FDW2501N双通道的N沟道MOSFET将数据转换成差分信号输出
DS90C124是一颗LVDS解串器，用来将夜视相机通过2线发送来的LVDS信号转换成TTL信号,通过FPGA采集数据后送到DSP做进一步的图像处理
LM2904 是一颗 1A、26V、高 PSRR、低压降稳压器
右上角的TPS5430 是一颗5.5V 至 36V 输入 3A 500kHz 降压转换器
左下解的TPS54310PWPR 是一颗输入电压为 3V 至 6V 的 3A 同步降压转换器
板子上一共有2颗丝印为625033的没找到具体型号，可以肯定是CAN收发器，其中一路与夜视相机通信，另一路与汽车的其它总线通信
下边是一颗英飞凌的ITS428L2，带有集成垂直功率FET的高端电源开关，提供嵌入式保护和诊断功能。
IDT74FCT3807是一颗时钟驱动器，左边有2颗晶振
与相机连接的使用HSD 4P接口
内部有2颗日本ELNA的电解电容
附上一段夜视电脑和夜视相机通信的数据，因为夜视电脑内保存的ID与相机不匹配，所以它们经过一段艰难的对话（附注释）后就进入了重复的一问一答模式。
