Automobile network routing system and method

Abstract

The invention provides an automobile network routing system and method. The automobile network routing system comprises a gateway that is connected with a diagnostic network and at least one analog change-over switch that is in hardwired connection with the gateway, wherein the input end of the analog change-over switch is connected with an entire automobile bus network, and the output end of the analog change-over switch is connected with a routing network; and the gateway is configured to make the entire automobile bus network communicate with the routing network and perform routing by controlling the state of the analog change-over switch when receiving a routing service request from the diagnostic network. According to the automobile network routing system and method provided by the invention, the deficiency of a traditional routing scheme in routing applications of diagnostic interfaces of the automobile gateway can be solved by adopting a controllable hardwired connection technical scheme, the parallel routing from multiple automobile bus networks to the diagnostic interfaces can be realized, the monitoring, acquisition and analysis of the diagnostic data of an automobile bus can be facilitated, the utilization efficiency of the automobile bus data can be increased, and thus the related diagnosis of the automobile bus can be more efficient, and the closure and security of the bus data can be ensured.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile network routing system and method. Background technique [0002] The automotive gateway mainly performs packet routing between different protocols and different rates to realize data sharing. A large amount of vehicle bus data can be obtained through the vehicle gateway, which can provide important support for technicians to analyze the vehicle usage and the overall status of the vehicle. [0003] Technicians usually obtain vehicle bus data through the diagnostic interface, therefore, the automotive gateway must be able to route messages from each network segment to the diagnostic interface. To prevent car bus data from being stolen via the diagnostic interface, the car gateway must also have data protection features to ensure a safe and reliable routing scheme. [0004] The current commonly used scheme is as figure 1 Shown: [0005] The diagnostic interface...

AI Technical Summary

Problems solved by technology

[0007] 1. It is impossible to obtain messages from multiple network segments at the same time, and it is impossible to observe the data of each network segment in a certain period at the same time;

[0008] 2. The routing relationship depends on the software program, and the reliability is difficult to estimate

[0010] 1. Network 0 may be overloaded;

[0011] 2. When different networks have the same ID message, the specific source of the message cannot be identified;

[0012] 3. The routing relationship depends on the software program, and the reliability is difficult to estimate

[0015] 1. When there are many networks, the diagnostic interface is not enough to connect all the networks;

[0016] 2. It needs to be changed before mass production;

[0017] 3. After mass production, it has the same disadvantages as plan 1
