The invention provides an automobile speed safety early warning method and system based on big data and an automobile. The method comprises the steps: identifying whether the current vehicle speed isoverspeed or not under the condition of identifying that a speed limit sign and a speed measuring device exist on the current road; if overspeed exists at the speed measuring position, recording the overspeed information, and comparing the overspeed information with traffic violation information recorded by the vehicle afterwards to judge whether the speed measuring device is started or not so asto provide prompt information about whether the speed measuring device is started or not for other vehicles passing through the position where the speed measuring device is located; therefore, driverspassing through the road section can be familiar with the road condition in advance, and the traffic danger caused by emergency deceleration when the drivers meet the speed measuring device due to the fact that the drivers are not familiar with the road condition is avoided.
本发明提供一种基于大数据的汽车车速安全预警方法、系统及车辆,在识别当前道路存在限速标志和测速装置的情况下,然后识别当前车速是否超速,如果在测速位置存在超速则记录该超速信息,并与该车辆事后被记录的交通违法信息进行存在性比较,从而判断该测速装置是否启用,以为经过该测速装置所在位置的其他车辆提供测速装置是否启用的提示信息;实现了为其他经过该路段的驾驶员提前熟悉该段路况,避免了由于不熟悉路况而造成的遇到测速装置而紧急减速造成的交通危险。
