High-availability network design method for intelligent networked automobile

The invention relates to a high-availability network design method for an intelligent networked automobile, and the method comprises the steps: configuring a communication card on a TBOX of a vehicle, and presetting the card data of two or more operators in the communication card; presetting a switching management strategy for switching conditions and parameters required by an operator and a switching execution strategy for specifically executing the switching management strategy, and configuring the switching management strategy and the switching execution strategy on the TBOX; and obtaining network environments where the user and the vehicle are located, inputting a switching instruction according to the network environments where the user and the vehicle are located, and executing the switching execution strategy. The method can avoid the limitation of the Internet of Vehicles service caused by poor network coverage of a single operator or service faults, designs a policy management and policy execution ar
