The patent abstract indicates that the invention discloses a method, device, vehicle, storage medium, and product for network isolation of intelligent cockpits based on network namespaces. The method includes: configuring the physical Ethernet card eth0 and the virtual LAN interface associated with eth0 in a dedicated network namespace, configuring the wireless LAN card WLAN0 in the default root namespace; completing network configuration for eth0 and WLAN0 respectively in the dedicated network namespace and the root namespace; when an application on the operating system of the intelligent cockpit needs to connect to the network, accessing the network based on the application’s access request in the dedicated network namespace or root namespace through the configured network card. This method prevents address conflicts and ensures communication security by separating eth0 and WLAN0 into different namespaces and determining the way to access the network based on the application’s access request when the application connects to the network.
