The invention relates to a communication device and a method capable of dynamically matching communication characteristic parameters. The communication device disclosed by the invention comprises a communication control module, communication cables and communication terminals. A bus control module and a bus dynamic matching module are arranged in the communication control module, and the communication control module completes a communication control processing function via the bus control module and the bus dynamic matching module, for achieving dynamic matching of communication characteristics. According to the method and the device provided by the invention, the same equipment can adapt to communication requirements of different communication terminals through dynamically matching the bus characteristic parameters without changing software and hardware under the condition of various communication requirements. During an actual application process, arrangement of the communication cables can be effectively reduced. Redevelopment of the communication control module and rearrangement of a communication circuit caused by variation of the communication mode are avoided.
