The invention discloses a vehicle-mounted intelligent terminal integrated with tire pressure monitoring. The vehicle-mounted intelligent terminal comprises a first CAN transceiver, an MCU, an APU, a tire pressure monitoring module, a GPS module and a second CAN transceiver. The first CAN transceiver, the MCU, the APU and the tire pressure monitoring module are connected in sequence; the GPS moduleis used for acquiring a radio frequency signal of a GPS antenna; the second CAN transceiver is used for receiving differential signals including vehicle speed, wheel speed and engine rotating speed in vehicle CAN network signals and converting the differential signals into level signals; and the tire pressure monitoring module is used for performing GPS data analysis and tire pressure monitoringoperation according to the radio frequency signal of the GPS module and the level signals of the second CAN transceiver. The tire pressure monitoring module is integrated into the vehicle-mounted intelligent terminal, GPS signals are used as assistance, the influence of wheel speed pulse changes caused by non-tire-pressure factors on a tire pressure algorithm is corrected, and the false alarm rateof the system is reduced.

    本发明公开了一种集成胎压监测的车载智能终端,包括:第一CAN收发器、MCU、APU、胎压监测模块、GPS模块和第二CAN收发器;所述第一CAN收发器、MCU、APU和胎压监测模块依次连接;所述GPS模块,用于获取GPS天线的射频信号;所述第二CAN收发器,用于接收车辆CAN网络信号中的包括车速、轮速、发动机转速在内的差分信号后转化为电平信号;所述胎压监测模块,用于根据GPS模块的射频信号和第二CAN收发器的电平信号,进行GPS数据解析和胎压监测运算。本发明将胎压监测模块集成到车载智能终端中,利用GPS信号作为辅助,修正非胎压因素引起轮速脉冲变化对胎压算法的影响,降低系统误报率。
