The invention discloses an automobile communication network topology, comprising a gateway, a first CAN module, a second CAN module and an LIN module, which are communicated with the gateway, wherein the first CAN module comprises a first CAN bus, a second CAN bus, two first ECU units and a plurality of second ECU units; the first ECU units are communicated with the first CAN bus and the second CAN bus; the second ECU unit is communicated with the first CAN bus or the second CAN bus; the first CAN bus and the second CAN bus are located in different network segments; the second CAN module comprises l CAN buses and a plurality of third ECU units which are communicated with each other via the CAN buses. Two first ECU units of the first CAN module can be used for simultaneously processing information of two CAN buses to reduce information content of a gateway route and information content which is received by each network segment from the gateway route in a communication network so as to improve usage rate and reliability of communication when a communication load of each network segment is limited. In addition, the cross-segment communication of the first ECU unit enables information transmission more efficient and timely.
