The invention relates to the technical field of vehicle transportation safety, and discloses an anti-rollover early warning method for a hazardous chemical substance transport vehicle, which comprises the following steps of: installing liquid level sensors on sections with equal distances on a tank body, monitoring intersection points A (y1, z1) and B (y2, z2) of a liquid surface and the tank body, deducing the mass center position of the section through the points A and B, and determining the rollover early warning of the hazardous chemical substance transport vehicle according to the mass center position of the section. Position sensors are installed at the center P of the axle and the center O of the tank body, the offset of the tank body on the y axis and the z axis is monitored, finally, the roll angle of the mass center of the tank body is deduced, similarly, the mass center position of another selected section is deduced, the mass center transmission track is predicted through the deduced mass center position, and the mass center roll angle threshold value theta k and-theta k which are set in advance are compared, so that the mass center roll angle is obtained. When theta is larger than or equal to theta k or smaller than or equal to-theta k, a rollover early warning is sent to the driver. Compared with the prior art, real-time performance of rollover early warning is achieved, monitoring of changes of the mass center of liquid in the tank is more accurate, and reliability is higher.
本发明涉及车辆运输安全技术领域,公开了一种危化品运输车防侧翻预警方法,包括:在罐体上选取距离相等的截面上安装液面传感器,监测液体表面与罐体的交点A(y1,z1)、B(y2,z2),通过A、B两点推断该截面的质心位置,再通过在车轴中心P与罐体中心O处安装位置传感器,监测罐体在y轴z轴的偏移量,最后推断出罐体质心的侧倾角,同理,推断出选取的另外截面质心位置,通过推断出的质心位置预测质心传递轨迹,对比提前设定的质心侧倾角阈值θk和‑θk,当θ≥θk或θ≤‑θk时,向驾驶员发出侧翻预警。与现有技术相比,本发明实现了侧翻预警的实时性,监测罐内液体质心的变化更加准确,可靠性更高。
