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.

    本发明提供了一种多传感器自适应加权融合汽车胎压检测装置及方法,设置于包括轮毂及外轮胎的汽车车轮上,包括:若干个压力传感器、A/D转换器、接口电路、微机模块、无线传输模块及车载单片机;所述压力传感器设置于所述外轮胎的侧面;所述A/D转换器与所述压力传感器电连接,用于将所述压力传感器采集的胎压信号进行A/D转换;所述接口电路与所述A/D转换器电连接,用于将所述A/D转换器转换后得到的胎压数据传输至微机模块;所述微机模块控制所述无线传输模块将采集的胎压数据传输至所述车载单片机;其中,所述车载单片机通过对所述胎压数据进行数据融合及阈值判断处理,判断是否需要进行胎压报警,如需要报警,则输出报警信号。
