1. A diagonal equal-hop heterogeneous composite redundancy domain architecture of an intelligent vehicle, comprising: a central gateway, an ADAS domain controller, a vehicle-mounted audio and video domain controller, a vehicle chassis domain controller and an energy domain controller;
wherein, the central gateway is coupled to the ADAS domain controller, the vehicle-mounted audio and video domain controller, the vehicle chassis domain controller and the energy domain controller in a communicative manner respectively, such that the central gateway, the ADAS domain controller, the vehicle-mounted audio and video domain controller, the vehicle chassis domain controller and the energy domain controller form a star connection topological structure; and
the ADAS domain controller is coupled to the vehicle-mounted audio and video domain controller and the energy domain controller respectively in a communicative manner, and the vehicle chassis domain controller is coupled to the vehicle-mounted audio and video domain controller and the energy domain controller respectively in a communicative manner, such that the ADAS domain controller, the vehicle-mounted audio and video domain controller, the vehicle chassis domain controller and the energy domain controller form an annular connection topological structure;
wherein a communication routing status among the central gateway, the ADAS domain controller, the vehicle-mounted audio and video domain controller, the vehicle chassis domain controller and the energy domain controller is detected in real time, and a corresponding routing work policy is selected based on the communication routing status;
wherein the routing work policy comprises:
a first routing work policy, in which the ADAS domain controller, the vehicle-mounted audio and video domain controller, the vehicle chassis domain controller and the energy domain controller transmit data thereamong through the central gateway when the central gateway operates normally;
a second routing work policy, in which the ADAS domain controller, the vehicle-mounted audio and video domain controller, the vehicle chassis domain controller and the energy domain controller transmit data thereamong through the annular connection topological structure when the central gateway fails;
a third routing work policy, in which when the central gateway fails and communication between the vehicle-mounted audio and video domain controller and the vehicle chassis domain controller also fails, a communication routing is: intercommunication between the vehicle-mounted audio and video domain controller and the ADAS domain controller, intercommunication between the ADAS domain controller and the energy domain controller, and communication between the energy domain controller and the vehicle chassis domain controller; and
a fourth routing work policy, in which when the central gateway fails and communication between the ADAS domain controller and the energy domain controller also fails, a communication routing is: intercommunication between the ADAS domain controller and the vehicle-mounted audio and video domain controller, intercommunication between the vehicle-mounted audio and video domain controller and the vehicle chassis domain controller, and intercommunication between the vehicle chassis domain controller and the energy domain controller.
