The invention discloses a vehicle safe driving early warning system and method based on Android mobile phone high-precision positioning, and the method comprises the steps: (1) carrying out the real-time positioning calculation of satellite data collected by an Android mobile phone chip, and obtaining the sub-meter positioning data; (2) preprocessing the acquired data, and matching the positioning data with a high-precision map by adopting a map matching algorithm to obtain the lane position of the vehicle; (3) formulating a safety early warning instruction according to the position of the vehicle in combination with related information; and (4) the platform formulates corresponding text, image and voice early warning according to the instruction information, and sends the text, image and voice early warning to an information prompt module for visual display. The invention provides a novel vehicle safe driving early warning method based on Android mobile phone high-precision positioning, the accident rate can be reduced to a great extent, and safe and efficient driving is ensured; the defects that the sight distance of a vehicle-mounted image and a distance measuring sensor is limited, the cost of a vehicle-road cooperation technology is high, and a vehicle-mounted system is slowly updated are overcome.

    本发明公开了一种基于Android手机高精度定位的车辆安全驾驶预警系统及方法,包括:(1)对Android手机芯片采集到的卫星数据进行实时定位解算,获得亚米级定位数据;(2)对获取的数据进行预处理,采用地图匹配算法对定位数据与高精地图进行匹配,得到车辆所处车道位置;(3)根据车辆位置,结合相关信息,制定安全预警指令;(4)平台根据指令信息,制定相应的文字、图像和语音预警,发送至信息提示模块进行可视化显示。本发明基于Android手机高精度定位提出了一种车辆安全驾驶预警的新方法,可极大程度降低事故率,保证行车安全高效;解决了车载图像、测距传感器视距受限以及车路协同技术成本高、车载系统更新缓慢等的弊端。
