The invention provides a vehicle tire burst early warning device and system. The device comprises an initial detection unit which is used for predicting the temperature difference along the way and acorresponding predicted tire pressure value according to a Cramer-Burner equation, and a driving state detection unit which is used for carrying out tire abnormality detection according to the speed limiting requirement of the current position of the vehicle and the speed detected in real time, starting a deviation processing program when the detection result is abnormal, and otherwise, entering cyclic detection; and after the deviation processing program is started, safety early warning is carried out, a nearby auxiliary road parking strategy is planned according to the current situation of the vehicle, and waiting for accident processing is carried out after parking. Therefore, a tire pressure monitoring system and an auxiliary/automatic driving system are effectively fused, the real-time condition of the tire is intelligently detected, an auxiliary function is automatically responded when an abnormality occurs, the driving safety of a driver and surrounding vehicles is guaranteed, and traffic accidents are reduced.
本发明提供一种车辆爆胎预警装置和系统,包括初始检测单元,用于根据克拉伯龙方程进行预测沿途温差及其对应的预测胎压值;和行驶状态检测单元,用于根据车辆当前位置的限速要求,和实时检测的速度进行轮胎异常检测,当检测结果为异常,则启动偏离处理程序,否则,进入循环检测;当所述偏离处理程序启动后,进入安全预警,并根据车辆当前情景规划就近辅路停靠策略,执行停靠后等待事故处理。从而有效将胎压监测系统与辅助/自动驾驶系统融合起来,智能检测车胎实时情况,并在发生异常时自动响应辅助功能,保障驾驶人员及周围车辆的行车安全,减少交通事故的发生。
