CAN COMMUNICATION SYSTEM


  1. OUTLINE


    1. The Controller Area Network (CAN) is a serial data communication network for real-time application. It is a multiplex communication network to be equipped in a vehicle, and has communication speeds of 500 kbps (HS-CAN) and the ability to detect malfunctions.

    2. HS-CAN consists of a V bus, local bus and sub bus 15.*1

    3. HS-CAN consists of a V bus, bus 2, bus 3, bus 5 and local bus.*2

    4. The communication wire used is a twisted-pair wire. The bus line has a high line (2.5 V to 3.5 V is applied) and a low line (1.5 V to 2.5 V is applied).

    5. The central gateway ECU has a gateway function and is used to transmit data between bus 2, bus 3, bus 5 and V bus.*2
