The invention discloses an automobile chassis system fault early warning method and system, and relates to the technical field of vehicle chassis, the fault monitoring system comprises a rotation angle sensor, a wheel speed sensor, a yaw velocity sensor, a data processing module, a storage module, a calculation module and an early warning module, the fault monitoring system can be matched with an existing electrical architecture, a new structure is not needed, and the fault early warning system is convenient to use. Potential faults of the chassis system can be found in time and early warning can be carried out, so that greater safety risks of the vehicle are avoided; according to the fault early warning method, by analyzing the relation between the vehicle lateral response and the vehicle steering state, whether a chassis system has potential faults or not is judged, whether the vehicle has the chassis faults or not is calculated and judged through steering sensitivity parameters, the current situation is further applied, a vehicle owner can be reminded to conduct inspection, or a 4S shop can be reminded to conduct maintenance, and the fault early warning effect is achieved. The method has the advantages of wide application range and low cost.

    本发明公开了一种汽车底盘系统故障预警方法及系统,涉及车辆底盘技术领域,所述的故障监测系统包括:转角传感器、轮速传感器、横摆角速度传感器、数据处理模块、存储模块、计算模块和预警模块,可与现有电气架构匹配,无需新增结构,可以及时发现底盘系统潜在故障问题并进行预警,避免车辆出现更大的安全风险;所述的故障预警方法,通过分析车辆侧向响应与车辆转向状态的关系,判断底盘系统是否存在潜在故障,用转向灵敏度参数计算和判断车辆是否存在底盘故障问题,当前情况进一步应用,可提示车主进行检查,或可提醒4S店进行维修,具有适用范围广、成本低的优势。
