Intelligent vehicle dynamic reconfigurable network system and network scheduling method

Abstract

The invention discloses an intelligent vehicle dynamic reconfigurable network system and a network scheduling method.The system comprises a central computing unit, a chassis domain controller, an entertainment domain controller, an intelligent driving domain controller and a vehicle body domain controller, and the central computing unit is connected with the chassis domain controller, the entertainment domain controller, the intelligent driving domain controller and the vehicle body domain controller through a network; the chassis domain controller, the entertainment domain controller, the intelligent driving domain controller and the vehicle body domain controller respectively comprise a plurality of intra-domain ECUs and are respectively connected with the plurality of intra-domain ECUs through a network. The network nodes in the network system are dynamically activated or standby, the vehicle network topology structure is changed in real time, waste of network resources caused by invalid information transmission is avoided from the source, and therefore the utilization rate of the network resources is increased; the basic period of reconfigurable network scheduling, the sampling period of the domain controller and the Baud rate of intra-domain information transmission are dynamically changed, and then the real-time performance of network messages and the high utilization rate of network bandwidth under the full working condition of the intelligent vehicle are achieved.

Description
