Abstract

The embodiment of the invention discloses a vehicle domain controller testing method, system and device and a storage medium. The vehicle domain controller testing method comprises the steps that the testing requirement of a vehicle domain controller is acquired; analyzing the test requirements to obtain test variables, a logical relationship among the test variables and test parameters; generating an abstract syntax tree based on the test variables, the logic relationship among the test variables and the test parameters; generating an optimal test case set based on the abstract syntax tree; and sending the optimal test case set to a lower computer. According to the embodiment of the invention, the test cases of the domain controllers of different types of vehicles can be automatically generated, and the development period of the vehicle domain controller test is shortened; and the optimal test case set is automatically generated from the test case set, and the optimal test case set is sent to the lower computer, so that redundancy generated in the compiling process of traversal test conditions is reduced, and automation of the test process of the vehicle domain controller is realized.

Description

technical field [0001] Embodiments of the present invention relate to vehicle control technologies, and in particular, to a vehicle domain controller testing method, system, device, and storage medium. Background technique [0002] With the increase in the use of automotive electronic chips and the rapid development of technologies such as in-vehicle gateways and autonomous driving, the number of electronic control units (ECUs) has also increased significantly. The traditional automotive electronic and electrical architecture is distributed, but now the number of ECUs in the car is huge, and the connection method of ECUs is changing from a distributed architecture to a centralized architecture. In a centralized architecture, using a domain controller with platformization, compatibility, high integration and good performance, the function of automotive electronic components divides the vehicle into several domains such as powertrain, intelligent cockpit, and autonomous drivin...

Problems solved by technology

[0003] At present, it is difficult to meet the requirements of domain controller test case writing by using the permutation and combination of different functions of different controllers to generate test basic units and manually write test cases.

Writing test cases by traversing test conditions will cause redundancy in the writing process, resulting in reduced test efficiency; for domain controllers of different types of vehicles, different types of test cases must be written, which makes the development cycle of vehicle domain controllers long ; and the screening of test cases needs to rely on the tester's experience and actual functional requirements, making it difficult to automate the testing process
