Abstract

The invention discloses a function node test system and belongs to the technical field of whole vehicle network testing. The function node test system comprises an instruction device, a control device and a test module set. The instruction device is used for issuing a control instruction; the control device is connected with the instruction device and used for forming a corresponding control loop according to the control instruction; the test module set is connected with the instruction device and further connected to a function node to be tested through the control device; the test module set includes a plurality of test modules, and is used for being connected or disconnected with the function node to be tested according to the control loop and executing corresponding test movement according to the control instruction; test results are uploaded to the control device by the test modules. By the adoption of the technical scheme, the function node test system has the advantages that different devices suitable for different test environments are integrated so as to achieve an overall performance test of the preset function node, and therefore equipment cost and human resource cost are reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle network testing, in particular to a functional node testing system. Background technique [0002] With the improvement of vehicle manufacturing technology and the reduction of vehicle manufacturing costs, household cars have gradually become popular in people's daily life, and in various special fields, there are many types of special vehicles. Generally speaking, when the vehicle is manufactured, the overall network performance of the vehicle needs to be tested, and the vehicle network usually uses a CAN (Control Area Network, Controller Area Network) bus network for connection and communication. It is very necessary to test the overall performance of the vehicle, such as the vehicle's turn signal function and alarm control function. At present, in the field of R&D and production of automotive electronics, the testing of CAN network nodes has been standardized. According to the test specificati...
