Automobile tire pressure monitoring system and method

Abstract

The embodiment of the invention discloses an automobile tire pressure monitoring system, and belongs to the field of automobiles. The system comprises a charging unit, a tire pressure monitoring unit,a central control unit, a communication unit and an internal power supply unit; the central control unit is electrically connected with the wireless charging unit and the tire pressure monitoring unit. The wireless charging unit is used for providing electric energy for electronic equipment in a wireless charging range, collecting electricity quantity information of the electronic equipment in real time and sending the electricity quantity information to the central control unit; the tire pressure monitoring unit is used for collecting tire pressure information of an automobile tire and sending the tire pressure information to the central control unit; the central control unit is electrically connected with the communication unit and used for processing the electricity quantity information and the tire pressure information and sending the processed electricity quantity information and the processed tire pressure information to the electronic equipment through the communication unit; the internal power supply unit is electrically connected with a battery pack and used for providing electric power support for the system. The embodiment of the invention further provides an automobiletire pressure monitoring method which can reduce the cost and improve the safety.

Description

technical field [0001] The invention belongs to the field of automobiles, in particular to an automobile tire pressure monitoring system and method. Background technique [0002] In recent years, with the increasingly intensified competition in the automobile industry, the price of automobiles has gradually decreased. In order to improve user experience and brand value, more safety modules and intelligent modules are often added to the vehicle to further improve the performance of drivers and passengers. car experience. Vehicle tire pressure monitoring system (Tire Pressure Monitoring System, TPMS) is a wireless transmission technology, the use of high-sensitivity miniature wireless sensor devices fixed in the car tires to collect car tire pressure, temperature and other data in the state of driving or stationary , and transmit the data to the host computer in the cab, display relevant data such as tire pressure and temperature in digital form in real time, and remind the d...
