HUD抬头数字显示是什么？OBD是什么意思？
HUD抬头数字显示可以实现驾驶过程中驾驶员行车不必低头，就可以通过HUD抬头显示器看到车辆信息，如途赛S200实现的车速、油耗、导航等都会显示在前挡风玻璃的小块区域内。从而避免分散对前方道路的注意力。
HUD抬头显示工作原理：
HUD是利用光学反射的原理，将重要的行车相关资讯投射在前挡风玻璃上面。相关信息投射高度大致与驾驶员的眼睛成水平，能让驾驶员轻易的了解当前行车资讯。
HUD设计的用意是让驾驶员不需要低头查看仪表的显示与资料，始终保持抬头的姿态，降低低头与抬头之间忽略外界环境的快速变化以及眼睛焦距需要不断调整产生的延迟与不适。
HUD抬头显示所投射的资料与行车安全有重要关系，譬如当前途赛S200实现的车速、转速、水温、电瓶电压 油耗等等数据，更有 超速报警 换档提醒 等功能。HUD显示的资讯根据当前的行车状况而变换，大大降低驾驶员看仪表盘的低头频率，以提高驾驶安全。
