应用于乘用车盲区智能辅助车载系统 技术领域
本发明涉及应用于乘用车盲区智能辅助车载系统，特别适合9座以下汽车。
背景技术
随着家用车在中国的日益普及，汽车成为人们的代步工具，但是由于汽车存在前行、转弯与倒车盲区,现有技术是通过雷达解决问题，或仅仅通过在后视镜安装摄像头解决，无法实现全方位立体监测周围情况，虽然，360°环视系统例如专利201611059915.5也有在高档家用车上应用，但是其视角范围小，无法实现实时动态监控，在先专利ZL201610222471.6虽然公开了一种车载系统，但是其结构简单，无法满足前行、转弯，实时动态显示。CN105599618也公开了车载系统，但是该系统的控制逻辑打转向灯后启动了雷达，雷达检测到有移动障碍物了在把信息传回主机控制器，主机控制器下达指令给摄像头工作，并把影像显示触发到显示屏显示。其无法实现实时在屏幕显示，需要来触发，BSD无法是在实时工作。CN201020112040.2一种无盲区驾驶可视系统需要红外传感器配合显示对应画面，而且无法实现环视，无法实现立体监测，其将处理运算都集中在处理器上，从而增加了处理器的工作负荷，从而产生反应延时(大概3-5秒时间)，反应速度慢，而汽车行驶中，路况瞬息万变，当司机依赖显示屏时，在这延时反应时间，无法做出正确应急判断，从而出现交通事故。另外，汽车厂家都是通过按照订制的工艺，流水线式生产，该系统属于订制，例如专利201611059915.5需要与汽车厂家沟通，预先安装，但是在实际社会生活中不是现实的，其影响汽车外观，需要重新汽车重新设计外观，汽车出厂标准验收标准的阻碍，不美观，不能满足个性化要求，每个司机的驾驶习惯不同。如何提供一种实现实时监控，反应灵活，无反应延时，适合家用车型，视角广阔，适合出厂后汽车根据司机个性化需要改造安装，成本低廉的盲区系统成为急需解决的技术问题。
发明内容
本发明所要解决的技术问题总的来说是提供一种应用于乘用车盲区智能辅助车载系统；在实际使用中，因为在城市拥挤道路低速行驶为常态，所以司机更关注车前面盲区。为了解决车前盲区，左侧摄像头安装在汽车左侧车尾附近位置向前照射；右侧摄像头安装在汽车右侧车尾附近位置向前照射。高速公路行驶的家用车，司机更关注变道超车与旁边车道车辆碰撞的风险，所以司机更关注车后、侧面盲区。为了解决变道超车盲区导致的风险，左侧摄像头安装在左侧后视镜向后照射，右侧摄像头安装在右侧后视镜向后照射。详细解决的 技术问题以及取得有益效果在后述内容以及结合具体实施方式中内容具体描述。

具体实施方式
参考图1-11所示，本实施例的应用于乘用车盲区智能辅助车载系统，包括安装在汽车外侧的四个或五个以上且用于对汽车周围摄像的盲区摄像头模组15；盲区摄像头模组15为以下两种组合之一：组合一，包括安装在汽车后部中间且用于拍摄汽车后方F盲区的后中摄像头3、以及前n型摄像系统，前n型摄像系统包括设置在汽车前部正中间且用于拍摄汽车前方A盲区的前中摄像头4、安装在左后车外侧上且用于拍摄汽车左前方B盲区的左前摄像头5、安装在右后车外侧上且用于拍摄汽车右前方D盲区的右前摄像头6。应用处理器22与视频切换逻辑控制器21组成选通电路。组合二，包括安装在汽车前部中间且用于拍摄汽车前方A盲区的前中摄像头4、以及后U型摄像系统，后U型摄像系统包括安装在左后视镜处且用于拍摄汽车左后方G盲区的左后摄像头1、安装在右后视镜处且用于拍摄汽车左后方J盲区的右后摄像头2、以及设置在汽车后部正中间且用于拍摄汽车后方F盲区的后中摄像头3。
前中摄像头4安装在汽车前部LOGO处或前保险杠居中位置；后中摄像头3安装在汽车后部LOGO处、后牌照灯一侧、或后保险杠居中位置；
本发明特别适合家用车等短车身的要求，另外，本发明创造性的安装前中摄像头4安装在汽车前部LOGO处或前保险杠居中位置，从而实现对车前盲区的拍摄，这是现有车载系统所不具备的，因为传统思想认为，前方安装摄像头迎风行驶，用于被尘土、泥泞弄脏，例如在汽车前置影像系统-201610548205.2与轿车前肓区观察器-201610023114.7以及传统安装方式，都是将其安装在前玻璃上或后视镜处，虽然可以实现前方拍摄，但是无法实现对车头前方的拍摄，而这块是司机的盲区，特别是前方有小孩、坑或石头、或进入车库时候，司机根本看不到，这是现有摄像头所不具备，另外，该位置摄像头在实际使用时，特别在高速、城市中行驶，不会被脏污遮挡，即使雨天脏了或在土地上行驶时候，擦拭一下即可。
当盲区摄像头模组15为组合一时，左前摄像头5安装在车体左侧后视镜处且向前照射或安装在汽车左侧车尾处且向前照射；右前摄像头6安装在车体右侧后视镜处且向前照射或安装在车体右侧摄像头安装在汽车右侧车尾处且向前照射；
当盲区摄像头模组15为组合二时，左后摄像头1安装在车体左侧后视镜处且向后照射或安装在汽车左侧车尾处且向后照射；右后摄像头2安装在车体右侧后视镜处且向后照射或安装在汽车右侧车尾处且向后照射。
输入单元、与输入单元电连接的应用处理器22、与应用处理器22电连接的输出单元；
输入单元包括输入端与盲区摄像头模组15输出端电连接的视频切换逻辑控制器21；
输出单元包括用于分屏显示影像或单屏显示盲区摄像头模组15摄像信息的显示屏8，显示屏8与应用处理器22电连接。
本发明通过前n型摄像系统将左前、右前、正前方盲区实景摄像信息或通过后U型摄像系统将左后、右后、正后方盲区实景摄像信息传输给应用处理器22，显示屏8显示对应位置的组合视频影像，满足了司机从显示屏一次观察多角度盲区的需求，减少司机多次扭头观看左右外部或内部后视镜带来的前方、后方二次盲区风险，同时减缓司机紧张心理、降低司机疲劳强度。
视频影像相比于传统的雷达倒车更直观，相比于雷达报警声速通过耳朵传输给大脑、眼睛捕捉信息更加方便直接迅速，缩短了司机的反应时间，降低了行车意外危险，对应雷达无法捕捉的特别障碍物，通过摄像头可以直接捕获。
本系统还包括以下方案中的至少一种：
方案a，输入单元还包括安装在汽车上且与视频切换逻辑控制器21电连接的环视摄像头模组7和/或ADAS系统20；环视摄像头模组7和/或ADAS系统20与应用处理器22通信连接；
通过与环视摄像头模组7和/或ADAS系统20结合，不仅弥补了盲区摄像头模组15的部分盲区实现更完美的全盲区解决方案以达到更佳效果，还可更好的进行障碍物测距。通过红黄绿三色锁定障碍物并进行距离数字数据显示提醒，并在显示器上框分绿黄红三色LED灯大面积交替显示做醒目提醒。在红色显示提醒时会有声音、震动做相应提醒。通过AV1-AV3三路屏幕画面接口，以及警示灯4路报警接口。
方案b，输出单元还包括与应用处理器22电连接的声/光/电提醒模块24和/或影像存储25；
方案c，输入单元还包括与视频切换逻辑控制器21电连接的触发信号接口17；其中，车动作信号19通过汽车总线/控制线路18与触发信号接口17电连接，车动作信号19包括汽车行驶的车速信号、手刹动作信号、倒车信号、转向信号、刹车动作信号、和/或车灯信号。
通过与接口与汽车线路连接，在视频切换逻辑控制器21中预设控制逻辑，将汽车动作信号与对应摄像头的控制开关/继电器对应，实现汽车不同动作，实现对应位置摄像头的打开，通过显示屏显示该位置的实时影像信息。
显示屏8电连接有背光驱动模块23、显示屏8与车前面板通过转轴支架13连接、显示屏8的左侧设置有警示汽车左侧有障碍物的左侧警示灯9、显示屏8的右侧设置有警示汽车右侧有障碍物的右侧警示灯10、显示屏8的上方设置有警示汽车前方有障碍物的前方警示灯11、和/或显示屏8的下方设置有警示汽车后方有障碍物后方警示灯12。
因为光对人的刺激远大于声音的刺激，通过设计警示灯，当遇到障碍物发光，从而缩短司机的反应时间，缩短大脑识别判断时间。
声/光/电提醒模块24包括由应用处理器22控制且安装在油门踏板背侧的振动电机14、由应用处理器22控制且安装在显示屏8上的警示灯、安装在方向盘背侧的振动电机14、由应用处理器22控制且安装在车座上的振动电机14、由应用处理器22控制闪烁的车灯、和/或由应用处理器22控制发声的汽车音响。

通过设计振动提醒，音响提醒，光电提醒，从而最大限度的提醒司机，特别适合长途司机，疲劳驾驶，夜间行驶，雨中行驶等情况。
当盲区摄像头模组15为组合二时，左后摄像头1与右后摄像头2的视角ε取值介于30°-45°之间或45°-60°之间或60°-75°之间；后中摄像头3的视角γ取值介于90°-120°之间或120°-150°之间；前中摄像头4的视角α取值介于90°-120°之间或120°-150°之间；

根据安装上述视角的汽车在行驶试验，上述角度参数可以有效避免后方两侧与正后的侧盲区，避免极大限度提高行车的安全性。
环视摄像头模组7拍摄的环视盲区覆盖后U型摄像系统拍摄存留的空白盲区C和/或前n型摄像系统拍摄空白盲区E。
可以采用本专利的组合，在汽车近侧还存在视角盲区，通过环视摄像头模组7拍摄的环视盲区覆盖后U型摄像系统拍摄存留的空白盲区C和/或前n型摄像系统拍摄空白盲区E。从而有效观察到空白盲区有小孩、大坑或石头等存在。

本专利根据车型及环视摄像头模组的有效可视范围，调整盲区摄像头模组的盲区范围确保其在环视范围内，从而实现各种场景下车辆盲区的完美解决方案；客户也可以根据自身需求，选择方案中的部分。
把盲区摄像头模组按照成组布置从而构成前n型摄像系统和/或后U型摄像系统。
通过视频切换逻辑控制器对输入的触发信号的逻辑判断及应用处理器的控制方案，实现盲区摄像头模组、环视摄像头模组的单视频影像在显示屏上的组合视频图像。通过增加ADAS系统及声/光/电提醒模块，可以实现报警信息以声、光、震动组合的方式提醒司机，满足了司机从显示屏一次观察多角度盲区的需求，减少司机多次扭头观看左右外部或内部后视镜带来的前方、后方二次盲区风险，同时减缓司机紧张心理、降低司机疲劳强度。
本发明对于适合9座以上的商务车，货车，公交车等大型长车身的汽车，可以使用 但使用效果不很理想。
本发明在测绘各种车型盲区数据基础上，基于符合人体工程学的视觉习惯、同时保证驾驶员在显示屏上能够一次看到更多、更全面、物体不变形、物距真实更清晰的视频影像的原则，本发明把盲区辅助摄像头按照成组布置、同时把盲区辅助摄像头的单视频影像按照盲区辅助应用场景优化组合，在汽车信号控制下形成输出在汽车显示屏上的成组视频影像。CPLD:5M160ZE64C5N；处理器为Altera公司的产品。
本发明源于汽车盲区问题的需求分析，设计合理、性价比高成本低廉、结实实用耐用、安全可靠、操作简单、省时省力、节约资金、结构紧凑且不改变司机的现有驾驶习惯使用方便。
