当汽车轮胎气压异常时，会影响汽车的舒适性及经济性，甚至会发生爆胎而威胁乘员的安全。现有的胎压监测系统只能被动的检测胎压，在发生爆胎时，对车辆进行制动避免或减少伤害，但不能主动的从根本上解决胎压异常的问题。 When the tire pressure of the car is abnormal, it will affect the comfort and economy of the car, and even a tire burst will threaten the safety of the occupants. Existing tire pressure monitoring systems can only detect tire pressure passively, and when a tire blows out, brake the vehicle to avoid or reduce damage, but cannot actively and fundamentally solve the problem of abnormal tire pressure.

The tire pressure control system includes: a tire pressure regulating device, an air compressor on the vehicle body, an air storage tank, and an air transmission pipeline from the gas storage tank to the tires; and a control unit that drives the tire pressure regulating device based on tire pressure information. But the shortcoming of this scheme is: the tire pressure control device is complicated, especially the inflation pipeline between the air tank on the car body and the tire is complicated or even difficult to realize. Secondly, the information such as tire pressure is transmitted to the control equipment on the car body through wireless means, and there are problems such as the communication is easily interfered and the equipment is complicated.
