Description

Technical Field

[0001] The present invention relates to the field of automotive electronic testing, and in particular to an intelligent integrated testing system, a control method and a computer-readable storage medium for an electronic control module in a complete vehicle environment. Background Art

[0002] China's automobile manufacturing industry is also rapidly developing towards electrification, networking and intelligence, which inevitably leads to the complexity of functional integration of on-board electronic control modules and the frequent release of software iterations, which brings greater challenges to integration testing.

[0003] As the core of the vehicle electronic control module, the vehicle electronic control software will be continuously updated during the development stage due to changes in demand and different vehicle models. For the OEM, all electronic control software needs to complete the refresh stability and reliability verification in the real vehicle or vehicle test bench environment before it is officially launched to ensure the safety of large-scale software updates in the factory or after-sales. Although the existing refresh test devices and methods have reduced labor costs to a certain extent, they only cover the test of the closed scene of the single module, and do not simulate the stability of the refresh function under the environmental conditions of the whole vehicle well, and also lack multi-dimensional detection of the security of the refresh file itself, such as a method and device for automatic refresh test of automobile ECU program (CN106874055A) and a flash writing test method, device, equipment and storage medium for a vehicle controller (CN115061450A).

[0004] Due to the further urgent demand for intelligence and networking, automobiles require more frequent data interaction between on-board electronic control modules. Therefore, detecting whether the communication data complies with the specification is gradually becoming one of the focuses of electronic control module software integration testing. Although some of the current communication test technologies test the bus general physical layer, link layer, etc., and there are also a small number of anti-interference tests, the test method is only a test of the single module in a closed scene, and there is also a lack of inspection and testing of the bus data cycle, length, deviation and other standards, especially the lack of automated integrated detection of on-board electronic control module bus data in the whole vehicle environment, such as an original vehicle bus simulation software and system for debugging and testing of on-board electronic products (CN107368063), a portable automatic test system for on-board bus (CN109375613A) and an automotive CAN communication fault test system, method, device and storage medium (CN113259209A).

[0005] With the increase in vehicle platforms and projects, and the frequent software iteration releases, software integration testers have an increasing demand for automated testing processes. However, due to the different styles of each tester, the engineering scripts produced independently are not unified, have poor portability, and low integration. Although existing diagnostic testing technologies can partially realize diagnostic automation and replace manual testing to a certain extent, they only focus on observing whether the module fault code is set as expected after fault injection, that is, they only cover a small part of the complete set of diagnostic services, and have poor portability between different architectures, such as an automated diagnostic test case generation system and method (CN111983998A).
