摘　　要：轮胎内的气压实时状况对于汽车的行驶安全以及性能来说都是非常重要的,如何对轮胎内的气压进行监测、控制、以及保持汽车所有轮胎内的气压相对平衡,一直以来就是一项十分重要的研究课题。然而目前市场上应用的轮胎压力监测系统TPMS(Tire Pressure Monitoring System),仅仅能对轮胎的气压进行监测,而不能自动的对轮胎内的气压做出反馈,来及时控制轮胎内的气压并保持所有轮胎内的气压平衡。为了解决这个问题,介绍设计的一种闭环汽车轮胎压力监测及控制系统,主要包括总体方案、硬件设计、软件设计、加密算法、性能分析。经试验和实际测试表明:该系统监测的数据可靠,更新及时,系统能有效的保持汽车所有轮胎内的气压相对平衡来增加了汽车的燃油效率,有很强的实用性。The Real-time tire pressure status inside the tire is very important to car driving safety and vehicle perfor-mance.How to monitor,control the tire pressure inside the tire,and maintain the air pressure inside all tires relativebalance,has always been a very important research topic.However,applications currently on the market tire pres-sure monitoring system（Tire Pressure Monitoring System,TPMS）,only can monitor the tire pressure,but not auto-matically make the air pressure inside the tire feedback to control the air pressure within the tire in time and keeppressure within all tires balance.To solve this problem,describes the design of a closed-loop tire pressure monitor-ing and control system,including overall program,hardware design,software design,encryption algorithms,perfor-mance analysis..The experiment and the test showed that：the system monitoring data is reliable and timely updates,which can effectively maintain the relative balance of all automobile tire pressure in order to increase the fuel effi-ciency of the car,which has a strong practical.
