Problems solved by technology
[0004] Traditional vehicle-mounted network management methods (such as Autosar and OSEK) are usually limited to node collaboration within a single subnet, and cross-subnet network management methods are relatively lacking. Network segment coordinated wake-up and hierarchical sleep

Embodiment Construction
[0063] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.
[0064] like figure 1 As shown, in the embodiment of the present invention, a global vehicle network management method is provided, which is in the vehicle network formed by the interconnection of multiple subnets through the same vehicle gateway (such as figure 2 shown), and each subnet includes at least one node (such as an ECU), the method includes the following steps:
[0065] Step S101, the vehicle-mounted gateway receives network management messages sent by each node in all sub-networks within a preset communication time;
[0066] The specific process is that the vehicle gateway can connect the subnets 1 to n through one of the CAN bus, LIN bus, and ETH (Ethernet) bus, or it can mix multiple buses among the CAN bus, LIN bus, and ETH bus. way to connect ...

The invention provides a global vehicle-mounted network management method, which is implemented on a vehicle-mounted network formed by interconnection of a plurality of subnetworks through the same vehicle-mounted gateway, each subnetwork comprises at least one node, and the method comprises the following steps: the vehicle-mounted gateway receives a network management message sent by each node in all the subnetworks within a preset communication time; the vehicle-mounted gateway corrects the signatures carried by the received network management messages and screens out the network management messages with the signatures meeting preset conditions; and in the screened network management messages, the vehicle-mounted gateway discards a network management message carrying a self dormancy signal or a network management message carrying a wake-up signal and not meeting a preset requirement. The invention further provides a global vehicle-mounted network management system and the vehicle-mounted gateway. By implementing the method, the vehicle-mounted network can be globally managed, illegal wake-up sources are filtered, and cross-network-segment collaborative wake-up and hierarchical dormancy are also realized.
Description
technical field [0001] The invention relates to the technical field of vehicle network communication management, in particular to a global vehicle network management method, system and vehicle gateway. Background technique [0002] In-vehicle network management usually includes OSEK (Open systems and the corresponding interfaces for automotive electronics) standard direct network management and AUTOSAR (Automotive Open System Architecture) network management and other methods. . Most OEM manufacturers adopt the Autosar network management strategy. When any node in the network has a network request, it will wake up the entire vehicle network, which can maximize the functional interaction requirements. However, it is easy to wake up by mistake, causing the vehicle network to fail to sleep. If the OSEK network management strategy is adopted, because the network status and request are transmitted through the token ring, and when a new application function needs to update the ne...
