The invention discloses an automobile high-speed driving safety early warning method and system based on tire working conditions. The system comprises the following parts: risk data acquisition: acquiring road surface environment, OBD data, tire original data and tire operation data; risk identification: identifying the risk sources and main risk causing factors of tire working condition, evaluating the risk values RAi of the risk sources Ai according to an automobile high-speed driving tire working condition risk source database, enabling the risk sources to comprise road driving condition risk sources, tire technical condition risk sources and vehicle control index risk source data; risk assessment: assessing the overall risk level of the tire working condition; and risk early warning: providing an early warning method for a driver according to the total risk level of the tire working condition, and reducing, eliminating or controlling the risk. Overall safety risk management is carried out on the tire working condition, traffic accidents caused by various risk sources of the tire working condition during the high-speed running of an automobile are avoided, and the high-speed running of the automobile is guaranteed.
本发明公开了一种基于轮胎工作条件的汽车高速行驶安全预警方法及系统,系统包括风险数据采集,采集路面环境、OBD数据以及轮胎原始数据及轮胎运行数据;风险识别,识别轮胎工作条件的风险源和主要致险因素,根据汽车高速行驶轮胎工作条件风险源数据库评估风险源A的风险值R,所述风险源包括道路行驶条件风险源、轮胎技术条件风险源及车辆控制指标风险源数据;风险评估,评估轮胎工作条件总体风险等级;风险预警,根据轮胎工作条件总体风险等级向驾驶员提供预警方法,降低、消除或控制风险。本发明采用对轮胎工作条件进行总体安全风险管理,避免汽车高速行驶时因轮胎工作条件各种风险源引发交通事故,保证汽车高速行驶。
