The invention relates to a distributed vehicle-mounted perception and vehicle-mounted communication device based on a controller area network (CAN) bus. The distributed vehicle-mounted perception and vehicle-mounted communication device comprises a vehicle-mounted sensor unit, a main control unit, a communication unit, a CAN transceiver unit, a power supply management module and an external power supply. The vehicle-mounted sensor unit comprises a three-shaft accelerator and a three-shaft gyroscope and is used for detecting six degree-of-freedom information. The main control unit comprises a single chip microcomputer and a program loading port used for loading single chip microcomputer program. The communication unit comprises a global system for mobile communication (GSM)/ general packet radio service (GPRS) module and a global position system (GPS) module and is used for being communicated with a remote monitoring center. The CAN transceiver is used for transmitting sensor signals and communication module s
