The invention discloses an automobile high-speed driving safety early warning method and system based on inner wheel difference. The system comprises risk data acquisition, risk identification, risk evaluation and risk early warning. According to the risk data acquisition, road environment, vehicle operation data, OBD data and vehicle original data are acquired. According to the risk identification, the risk source of the inner wheel difference and the characteristics of the risk source in the turning driving process of an automobile are identified; the risk value RAi of the risk source Ai isevaluated according to an automobile turning driving inner wheel difference risk source database. According to the risk evaluation, the overall risk level of the inner wheel difference is evaluated. According to the risk early warning, an early warning method is provided for a driver according to the total risk level of the inner wheel difference, and the risk can be reduced, eliminated or controlled. Overall safety risk management is carried out on the inner wheel difference, traffic accidents caused by various risk sources of the inner wheel difference during the turning driving of the automobile are avoided, and the turning driving safety of the automobile is guaranteed.

    本发明公开了一种基于内轮差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,采集道路环境、车辆运行数据、OBD数据以及车辆原始数据;风险识别,识别汽车转弯行驶过程中内轮差的风险源及其特性。根据汽车转弯行驶内轮差风险源数据库评估风险源A的风险值R,风险评估,评估内轮差总体风险等级;风险预警,根据内轮差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。本发明采用对内轮差进行总体安全风险管理,避免汽车转弯行驶时因内轮差各种风险源引发交通事故,保证汽车转弯行驶安全。
