The invention provides a tire underpressure proportion monitoring method based on an indirect tire pressure monitoring system, which comprises the following steps: on the basis of the existing indirect tire pressure monitoring algorithm, comprehensively calculating the detection results of a tire relative rolling radius model and a tire vibration frequency spectrum model, and meanwhile, comprehensively calculating a single-wheel underpressure rapid analysis module; finally, the estimated value of the tire underpressure proportion is obtained, and the actual vehicle speed, the underpressure proportion of each tire and the underpressure degree of each tire are displayed in real time through a display module. According to the process, the advantages of an indirect tire pressure monitoring system can be brought into full play, the visualization of the tire pressure is realized on the basis of not needing an additional sensor or other equipment, and the driving safety is effectively improved.
本发明提供了一种基于间接式胎压监测系统的轮胎欠压比例监测方法,该方法以现有的间接式胎压监测算法为基础,将轮胎相对滚动半径模型和轮胎振动频率谱模型的检测结果综合计算,同时综合计算单轮欠压快速分析模块,最终得出轮胎欠压比例的估计值,并利用显示模块实时显示实际车速、各个轮胎的欠压比例及轮胎的欠压程度;上述过程可充分发挥间接式胎压监测系统的优势,在不需借助额外的传感器或其他设备的基础上,实现了轮胎压力的可视化,有效提高了行车安全性。
