The invention provides a multi-sensor self-adaptive weighted fusion automobile tire pressure detection device and method, which are arranged on an automobile wheel comprising a hub and an outer tire.The multi-sensor self-adaptive weighted fusion automobile tire pressure detection device comprise a plurality of pressure sensors, an A/D converter, an interface circuit, a microcomputer module, a wireless transmission module and a vehicle-mounted single-chip microcomputer. The pressure sensor is arranged on the side surface of the outer tire; the A/D converter is electrically connected with the pressure sensor and is used for performing A/D conversion on the tire pressure signal acquired by the pressure sensor; the interface circuit is electrically connected with the A/D converter and is usedfor transmitting tire pressure data converted by the A/D converter to the microcomputer module; the microcomputer module controls the wireless transmission module to transmit collected tire pressuredata to the vehicle-mounted single-chip microcomputer. The vehicle-mounted single-chip microcomputer is used for judging whether tire pressure alarm needs to be carried out or not by carrying out datafusion and threshold value judgment processing on the tire pressure data, and outputting an alarm signal if the tire pressure alarm needs to be carried out.
