The invention discloses a wheel falling-off early warning system, relates to the technical field of automobile safety, and solves the technical problem that the wheel falling-off early warning efficiency is low due to the fact that abnormal judgment is carried out by calculating a state coefficient of a wheel and comparing the state coefficient with a fixed threshold in the prior art to cause a false alarm condition in abnormal recognition of wheel falling-off. The method comprises the steps of obtaining wheel data, vehicle data and road surface data; calculating a wheel wear coefficient according to the historical wheel data and the historical vehicle data; calculating a comprehensive abnormal coefficient of the wheel after calculating an external abnormal coefficient according to the wheel data; generating an alarm signal according to the comprehensive abnormal coefficient; according to the technical scheme, a prompt is made according to the alarm signal, factors in the aspects of wheel abrasion, wheel vibration and the like are considered in factors affecting wheel falling, related threshold values are dynamically adjusted according to the running states of the wheels on different roads, the false alarm situation during running on bumpy roads can be reduced, and meanwhile the wheel falling early warning efficiency is improved.

    本申请公开了一种车轮脱落预警系统,涉及汽车安全技术领域,解决了现有技术通过计算车轮的状态系数与固定阈值比较进行异常判断,导致车轮脱落的异常识别会存在误报情况发生,进而导致车轮脱落预警效率较低的技术问题;通过获取车轮数据、车辆数据以及路面数据;根据历史车轮数据和历史车辆数据计算车轮磨损系数;根据车轮数据计算外部异常系数之后计算车轮综合异常系数;根据综合异常系数生成警报信号;根据警报信号做出提示,将车轮磨损以及车轮振动等方面的因素考虑在影响车轮脱落的因素中,根据不同道路车轮的运行状态动态调整相关阈值,能够减少颠簸道路行驶时的误报情况,同时提升了车轮脱落预警的效率。
