System for identifying positions of pressure sensors in automobile tire pressure monitoring system and automobile tire pressure monitoring system

The utility model provides a system for identifying positions of pressure sensors in an automobile tire pressure monitoring system and the automobile tire pressure monitoring system. Tire pressure sensors used for monitoring tire pressure are configured on tires of an automobile. The system comprises a plurality of acquisition modules and judgment modules. The acquisition modules acquire steering wheel steering angle signals, wheel acceleration speeds transmitted by the pressure sensors of the all tires, break signals of the automobile, automobile acceleration signals and wheel pressure transmitted by the pressure sensors of the all tires respectively; and the judgment modules determine that the sensors are located on which tire according to the acquired signals. With the adoption of the system, that the sensors are located on which tire can be determined with as less components as possible.
