Problems solved by technology

[0006] It can be seen from the above that the defects of the two ways of implementing message routing are: the coupling between the upper layer application and the underlying communication driver software is strong, and the independence of the two is poor, which increases the difficulty of software risk control, and when the routing table changes, The entire software project needs to be recompiled, prolonging the development cycle of the routing function

Embodiment 1

[0067] See figure 1 , which shows a flow chart of the message routing processing method provided by the present application, which may include the following steps:

[0068] Step S11: Receive a message receiving instruction and received message information sent by the communication driver software module.

[0069] In this embodiment, the message receiving is completed by the communication driver software module. Wherein, when the communication driver software module receives the message, it notifies the upper layer application module through the receiving instruction callback function, which is recorded as the Router module in this embodiment, and sends the received message information of the received message to the Router module.

[0070] Wherein, the received message information includes: received physical channel, message ID, message data length and message data.

[0071] It should be noted that the communication driver software module needs to ensure that it can accept me...

Embodiment 2

[0128] Corresponding to the foregoing method embodiments, this embodiment provides a packet routing processing device, please refer to Figure 4 , The message routing processing device includes: a receiving module 41 , a reading module 42 , a searching module 43 , an obtaining module 44 , a sending module 45 and a communication driver software module 46 .

[0129] The receiving module 41 is configured to receive a message receiving instruction and received message information sent by the communication driver software module 46 .

[0130] The reading module 42 is used for reading the routing configuration data list from the independent memory block.

[0131] A search module 43, configured to search in the routing configuration data list whether there is a routing relationship corresponding to the received message information, if the routing relationship corresponding to the received message information is found in the routing configuration data list, Then, the acquiring module...

Abstract

The present invention provides a message routing processing method and device. The message routing processing method includes: receiving a message receiving instruction sent by a communication driver software module and receiving message information; reading a routing configuration data list from an independent memory block, And look up whether there is a routing relationship corresponding to the received message information in the routing configuration data list; if the routing relationship corresponding to the receiving message information is found in the routing configuration data list, obtain the target message from the routing relationship corresponding to the receiving message information send the information of the target message to the communication driver software module; the communication driver software module sends the target message to the target network according to the information of the target message. The invention reduces the difficulty of software risk control and shortens the development cycle of routing functions.

Description

technical field [0001] The invention relates to the field of automotive ECU (Electronic Control Unit, Electronic Control Unit) software and hardware design, in particular to a message routing processing method and device. Background technique [0002] For the ECU (Electronic Control Unit, Electronic Control Unit) with the gateway function in the car, the routing function (including message routing (receiving the source message from the source network, obtaining the identification of the target message according to the identification of the source message, and according to the target Message identification (routing the target message to the target network) and signal routing) are one of its main functions. [0003] Among them, there are currently two ways to implement packet routing, specifically: the first method: a routing function implements a pair of packet routing relationships, and the routing table is finally embodied as a series of routing functions, where the routing...
