description The invention discloses a CAN communication address dynamic automatic allocation method. The method comprises the following steps: S1, selecting a plurality of bits of data in a CAN communication address as address characteristic parameters; s2, each device on the CAN bus sends an address identification frame of a unique identifier to the bus; s3, the controller of each device compares the size of the address identification frame of the controller with the size of the address identification frame of each device on the bus, and adjusts the address characteristic parameter of the controller; and S4, each device on the CAN bus monitors the online conditions of other devices in real time, and after it is monitored that a device exits from the bus, the address characteristic parameters of the device are adjusted. According to the invention, the dynamic automatic distribution of the CAN communication address can be realized, manual intervention is not needed, and the distribution efficiency is improved. 本发明公开了一种CAN
