System and method for testing automotive electronic diagnostic software

Abstract

The invention discloses a system and method for testing automotive electronic diagnostic software, which is characterized in that the system comprises a diagnostic Tester packet, an electronic control unit (ECU) model platform and a communication interface, wherein the diagnostic Tester packet comprises a display / analysis module, a sending / receiving information module, a bus information monitoring module and a Tester communication module; the ECU model platform comprises a simulation ECU application module, a simulation ECU system module, a diagnostic module, a storage module and a platform communication module; the communication interface is used for connecting the diagnostic Tester with the ECU model platform, and converting communication buses with different types into consistent communication buses for transmitting the communication information; and the sending / receiving information module sends a diagnostic service request and receives a diagnostic service response by the Tester communication module, and transmits diagnostic service request data and diagnostic service response data to the display / analysis module. By using the system and method for testing the automotive electronic diagnostic software, the diagnostic software can be diagnosed and tested at any time, thus reducing the workload of developers and greatly improving development efficiency.

Description

technical field [0001] The invention relates to the field of automotive electronic embedded software testing, in particular to a testing system and method for automotive electronic diagnostic software. Background technique [0002] At present, automotive diagnostic detection systems are all used in ECU fault diagnosis. In the stage of developing diagnostic software, to test whether the diagnostic software meets the service requirements in the diagnostic agreement, there are two existing public technical solutions in China. The first one requires actual The advantage of this method is that it can be tested in the actual ECU hardware environment, which makes the test accuracy very high, but it is relatively difficult to adjust the running state of the ECU, and the testing process of the diagnostic software is complicated. Therefore, the efficiency is low; the second method is to simulate the ECU node by pure software, run the diagnostic software, and then test it. Nodes are i...
