Abstract

A dynamic reconfigurable network system and network scheduling method for an intelligent vehicle, the system includes a central computing unit, a chassis domain controller, an entertainment domain controller, an intelligent driving domain controller, and a vehicle body domain controller, the central computing unit and the chassis domain controller The chassis domain controller, entertainment domain controller, smart driving domain controller, and body domain controller respectively include multiple ECUs in the domain and are respectively connected to each other through the network. Connect with multiple ECUs in the domain through the network. By dynamically activating or standby network nodes in the network system, the topology of the vehicle network can be changed in real time, and the waste of network resources caused by invalid information transmission can be avoided from the source, thereby improving the utilization of network resources; dynamic changes can reconfigure the basic network scheduling Period, the sampling period of the domain controller and the baud rate of information transmission in the domain, so as to realize the real-time network information and high utilization rate of network bandwidth under all working conditions of intelligent vehicles.
