Network control method and system based on routing function

Abstract

The invention discloses a network control method and system based on a routing function. The method comprises the steps of waking up a gateway when one network segment receives a message needing to berouted under a gateway dormancy condition, determining a source network segment and a target network segment corresponding to the message needing to be routed based on a routing table, and waking upthe source network segment and the target network segment corresponding to the message needing to be routed; after one network segment is used as a source network segment or a target network segment to be awakened, keeping the source network segment or the target network segment in an awakening state when the message is not received again or the message needs to be routed within the awakening state maintaining time; when the message is received again or the message needs to be routed, re-timing the wake-up state maintaining time of the source network segment or the target network segment; andswitching the source network segment or the target network segment from the awakening state to the dormant state when the awakening time reaches the awakening state maintaining time and the message isnot received again or the message needs to be routed. According to the invention, sleep wake-up control can be simply and effectively carried out on the gateway and the network segment through the routing table.

Description

technical field [0001] The invention relates to the technical field of automotive electronics, in particular to a routing function-based network control method and system. Background technique [0002] Such as figure 1 Shown is the current typical vehicle network architecture. The gateway divides the vehicle network into multiple network segments, and is the hub for data interaction 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 the message received in a certain network segment (source network segment) to another network segment (target network segment). [0003] At present, in order to reduce the power consumption of the vehicle and effectively manage each controller to switch between sleep and wake states 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 management ...

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
