摘 要：輪胎破損漏氣較為隱蔽，輪胎胎壓異常肉眼不易察覺。行駛中的汽車胎壓過低或過高都十分危險(xiǎn)。因此胎壓監(jiān)測系統(tǒng)是車輛主動安全系統(tǒng)中的重要組成。從2020年1月1日起，在我國生產(chǎn)的所有車輛必須強(qiáng)制安裝胎壓監(jiān)測系統(tǒng)。本文以某車型胎壓監(jiān)控系統(tǒng)在行駛過程中后輪胎壓信號出現(xiàn)偶發(fā)丟失的故障為例進(jìn)行具體闡述。介紹了胎壓監(jiān)測系統(tǒng)的組成，分類，作用，工作原理以及影響因素，并通過零部件替換、機(jī)理分析等鎖定某車型胎壓信號丟失故障要因?yàn)锳VM視頻線破損導(dǎo)致車內(nèi)電磁環(huán)境干擾過大，進(jìn)而導(dǎo)致胎壓信號丟失。

Research on the Tire Pressure Monitoring System based on a Certain Vehicle Type
Ou Zengkai Yang HuiJu Bu Qingxin
Abstract：Tire breakage leakage is hidden， and tire pressure abnormal to the naked eye is not easy to detect. It is dangerous to drive a car with too low or too high tire pressure. Therefore， the tire pressure monitoring system is an important component of the active safety system of the vehicle. From January 1， 2020 on， all vehicles manufactured in China must be forced to install a tire pressure monitoring system. This paper gives a specific explanation of the failure of the tire pressure monitoring system after the tire pressure signal is occasionally lost during driving. This paper introduces the composition， classification， function， working principle and influence factors of the tire pressure monitoring system， and locks the failure of the tire pressure signal of a certain model by component replacement， mechanism analysis， etc. because the AVM video cable breakage causes the electromagnetic environment interference in the car to be too large， which leads to the loss of the tire pressure signal.
Key words：Tire pressure monitoring， BCM，TPMS
