A network control method and system based on routing function

Abstract

The invention discloses a routing function-based network control method and system. The method includes: when the gateway is dormant, one of the network segments receives a message that needs to be routed, wakes up the gateway, and determines the message that needs to be routed based on the routing table. Corresponding source network segment and target network segment, wake up the source network segment and target network segment corresponding to the message that needs to be routed; when one of the network segments is awakened as the source network segment or target network segment, it is not activated within the wake-up state maintenance time. When the message is received again or the message needs to be routed, keep the source network segment or the target network segment in the wake-up state; when the message is received again or the message needs to be routed, re-time the wake-up state of the source network segment or the target network segment Maintenance time; when the wake-up time reaches the wake-up state maintenance time, and no message is received again or the message needs to be routed, the source network segment or target network segment is switched from the wake-up state to the sleep state. The present invention can simply and effectively perform dormancy wake-up control on gateways and network segments through routing tables.

Description

technical field [0001] The invention relates to the technical field of automotive electronics, in particular to a network control method and system based on a routing function. Background technique [0002] like figure 1 As shown, it is a typical vehicle network architecture at present. The gateway divides the entire vehicle network into multiple network segments, and is the hub for data exchange between the various controllers of the vehicle. The initial, most basic and core function of the gateway is the routing function, that is, the process of sending packets received in a certain network segment (source network segment) to another network segment (destination network segment). [0003] At present, in order to reduce the power consumption of the whole vehicle and effectively manage each controller to switch the sleep-wake state in a timely manner, the architecture engineer requires all or part of the network segments of the gateway to support a certain type of network ...

AI Technical Summary

Problems solved by technology

[0004] It can be seen that the control method adopted by the existing technology, with the increasingly complex vehicle architecture and vehicle network, the number of network segments of the gateway is also increasing, which requires architecture engineers to have more practical experience. Invest more energy in designing a more reliable and reasonable sleep and wake-up strategy; at the same time, when there is a problem with the whole vehicle, the complex sleep and wake-up logic will complicate simple problems and increase the difficulty of troubleshooting
