Description

商用车盲区多画面视频成组显示系统 技术领域
本发明涉及商用车盲区多画面视频成组显示系统。
背景技术
目前采用视频影像技术的乘用车盲区辅助驾驶的主流产品为360度全景环视、及安装在左右后视镜及内后视镜的盲区辅助摄像头产品。由于360度全景环视存在图像严重畸变、有效图像的范围距离太近、不符合人的传统视觉习惯等不足之处，用户即使安装全景环视产品，使用频率也很低。左右及内后视视盲区产品仅解决了乘用车左右后区域的部分盲区。乘用车盲区辅助显示屏与娱乐导航屏共用，用户使用时两种产品功能时相互影响；同时现有盲区辅助视频图像全部为单画面、不能一次显示符合视觉习惯的多个摄像头的组合视频影像，致使司机在娱乐屏上一次看到的盲区辅助视频影像的综合信息很少。现有乘用车BSD产品在车速高于一定速度、报警信息才以灯光闪烁形式在左右后视镜上显示，报警信息仅有灯光单一显示且显示位置虽符合司机驾驶习惯但距离司机较远。由于商用车车型的特殊性，商用车盲区较乘用车更大，但是因为商用车司机的职业化、安装显示屏较乘用车更少或倒车后视屏功能单一、新技术应用较乘用车滞后等原因，现有商用车盲区辅助产品基本为空白。现有公交车标配智能调度屏，如果盲区辅助显示屏与智能调度屏共用，用户使用时两种产品功能会相互影响。现有盲区辅助视频影像全部为单画面、不能一次显示符合视觉习惯的多个摄像头的成组视频影像，致使司机在调度屏上一次看到的盲区辅助视频影像的综合信息太少。同时现有显示屏的安装位置偏下，司机在看显示屏的瞬间会产生前方二次盲区的风险。随着都市公交优先、物流业迅猛发展、职业司机的匮乏及其技能下降，商用车因盲区导致的事故频发。基于商用车以安全运营及企业效益为目的，商用车盲区辅助产品除了具备盲区辅助功能之外，更应该具备汽车外部无盲区的专业录像的功能。用户迫切需要解决以上问题，更需要安装简易、不改变现有人的视觉及驾驶习惯、能够更安全、更舒适地从显示屏上一次获得更多盲区辅助信息的综合解决方案。

其中车速的低速与高速之间的预设车速值根据用户要求或车辆限速规定标准设定。驾驶员对危急情况处理(紧急刹车)：0.2-0.4秒，该反应时间与对应方案中车速的乘积为最小的障碍物安全距离。其中，盲区的范围，即摄像头的有效覆盖范围，对于本领域技术人员来说是显而易见的，一般定义包括司机在驾驶汽车时候的看不到的区域，当然，对于司机可以看到区域，本专利的摄像头更可以覆盖，摄像头的有效覆盖范围可以达到30米。CPLD:5M160ZE64C5N；处理器为Altera公司的产品。作为优选，在汽车前部按照n型成组布置的前组摄像头；正中摄像头安装在汽车前部LOGO附近，或前保险杠居中位置附近；左前摄像头安装在左侧后视镜向前照射，或左前摄像头安装在汽车左侧车尾附近位置向前照射；右前摄像头安装在右侧后视镜向前照射，或右前摄像头安装在汽车右侧车尾附近位置向前照射；在汽车后部按照U型成组布置的后组摄像头；后中摄像头安装在汽车后部LOGO附近、后牌照灯附近、或后保险杠居中位置附近；左后摄像头安装在左侧后视镜向后照射；右后摄像头安装在右侧后视镜向后照射。经过大量路试，根据司机操作汽车信号习惯及考虑盲区辅助产品的驾驶场景，本发明把CAN/手动、左转向、右转向、倒车、刹车、大灯汽车信号作为控制触发盲区辅助摄像头单视频影像自动切换的信号源，实现显示屏上分屏或单屏显示的成组视频影像。其中正中摄像头除具有盲区辅助、录像功能外，还可扩展具有车道偏离及前向碰撞预警功能；左/右摄像头除具有盲区辅助、录像功能外，还可扩展具有车道偏离预警功能。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。高速公路行驶的商用车辆，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。另外，基于商用车前部多为平头，为了达到更好的盲区辅助效果，商用车左前摄像头安装在汽车左侧车尾附近位置向前照射；右前摄像头安装在汽车右侧车尾附近位置向前照射。对于车前部有较长车头的商用车，如校车，商务车、出租车，可以采用左前摄像头安装在左侧后视镜向前照射，右前摄像头安装在右侧后视镜向前照射；但最佳方案还是左前摄像头安装在汽车左侧车尾附近位置向前照射；右前摄像头安装在汽车右侧车尾附近位置向前照射都是本发明的保护范围。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。
