摘　　要：轮胎作为车辆与地面的唯一接触部件,轮胎中的气压变化对车辆的驾驶舒适性、燃油经济性和道路安全有着显著影响,但是,驾驶员经常忽略轮胎的状况和轮胎内的压力值,这为交通安全带来了隐患。有源电子设备尺寸和功耗的不断减小以及无线通信的进步使得无线传感器能够在工业和汽车应用中得到广泛使用,轮胎压力监测系统(TPMS)由每个轮胎内的无线轮胎压力传感器(TPS)模块和汽车内的单个接收器组成,汽车轮胎压力的监测和解决方法已成为安全驾驶的重要发展方向。文章设计的轮胎压力监测系统使用SP12传感器,采用了低频唤醒方法,选用了ABLE(爱博尔)公司的ER2450提供稳定的电源用于给系统供电,并通过后续系统的验证和测试结果,说明该汽车轮胎压力监控系统软件设计的合理性和可行性。研究结果对提高汽车的行驶安全性有一定参考价值。As the only contact between the vehicle and the ground, the change of air pressure in the tire has a significant impact on the driving comfort, fuel economy and road safety of the vehicle.However, the driver often ignores the condition of the tire and the pressure value in the tire, which is very important for traffic. Security brings hidden dangers. Continuing reductions in the size and power consumption of active electronics and advancements in wireless communications have enabled the widespread use of wireless sensors in industrial and automotive applications. Tire pressure monitoring systems(TPMS) consist of wireless tire pressure sensors(TPS) within each tire module and a single receiver in the car, the monitoring and solution of car tire pressure has become an important development direction for safe driving. The tire pressure monitoring system designed in this paper uses the SP12 sensor, adopts the low-frequency wake-up method, and selects the ER2450of ABLE(Aiboer) company to provide a stable power supply for powering the system. The rationality and feasibility of software design of automobile tire pressure monitoring system.
