Controller applied to automobile tire pressure monitoring and body control

The invention discloses a controller applied to automobile tire pressure monitoring and body control, which comprises an MCU and a control module, wherein the control module comprises a radio frequency receiving module, a CAN transmitting and receiving circuit and a BCM circuit; and the radio frequency receiving module is used for receiving an RKE radio frequency signal and a tire pressure sensor radio frequency signal. The controller combines RKE radio frequency receiving of the traditional BCM and radio frequency receiving of the tire pressure monitoring; when the system works, if the controller MCU monitors a remote control command transmitted by a remote controller via the radio frequency receiving module, corresponding operation such as unlocking, locking and automobile searching can be made according to a functional logic definition, thereby realizing a remote control function; and if the controller MCU monitors the tire pressure information, the information is processed into a CAN bus signal, the signal is transmitted to an instrument or an entertainment terminal for display, thereby realizing a tire pressure monitoring function. Through integrating TPMS, the automobile production cost is effectively reduced, and the automobile electronic structure is simplified.
