Vehicle-mounted network connection central domain controller

The invention provides a vehicle-mounted network connection central domain controller. The vehicle-mounted network connection central domain controller comprises a system power supply, and comprises an MCU real-time processing unit, an MPU processing unit, an in-vehicle wireless communication unit, a 4G communication unit, an LTE-V communication unit, a positioning unit, an in-vehicle network transceiving unit, an RGMII routing unit and a hardware security unit which are all electrically connected with the system power supply. The vehicle-mounted network connection central domain controller integrates central gateway domain controller architectures of an in-vehicle network and an out-vehicle network, has higher integration level and expandability. Due to factors such as reduction of the number of chips, reuse of chip resources and saving of high-speed interconnection wire harnesses, the framework has an obvious cost advantage than an original separation framework scheme, the total energy consumption of a netw
