Embodiment Construction

[0019] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0020] A method for establishing a hardware-in-the-loop test case library for a new energy vehicle integrated controller of the present invention is characterized in that it includes the following steps:

[0021] Step 1: Divide the new energy vehicle controller software and hardware resources that need to be tested into the following four categories according to the types and implementation methods of the software and hardware resources: model, new energy vehicle integrated controller test hardware board Cards (including power boards, digital boards, analog boards, motor boards, network boards, and fault injection boards), network configuration files for new energy vehicle integrated controller testing (CAN / LIN configuration files) . For the test case of the hardware-in-the-loop test of the new energy vehicle controller under test, the model inc...

Abstract

The invention relates to a method for establishing a hardware-in-the-loop test case library for a new energy vehicle integrated controller, comprising: 1. The new energy vehicle controller software and hardware resources to be tested are determined according to the type and implementation of the software and hardware resources 2. Establish test items; 3. Distinguish between the calibration quantity and the measurement quantity; 4. Associate the calibration quantity distinguished in step 3 with the A2L file; 5. Define the test item to store variables during the test process Test space; 6. Write the function to be tested as a test case; 7. Define the address of the test case library. The present invention fully considers the relative independence of software and hardware configuration, adopts the method of separately configuring models, test software, test hardware, test tools, and test cases, and finally synthesizes them to establish a test case library and conduct tests.

Description

technical field [0001] The invention relates to the technical field of vehicle controllers, in particular to a method for establishing a hardware-in-the-loop test case library for a new energy vehicle integrated controller. Background technique [0002] At present, the software functions of the vehicle controller of new energy vehicles have increased exponentially compared with traditional vehicles. For the verification of software functions and hardware robustness, a more convenient method is to use hardware-in-the-loop testing. Nowadays, the writing of test cases in hardware-in-the-loop testing focuses on design from five aspects: test requirements management, test case type classification, traceability of product functional requirements and test requirements, and coverage relationship between test requirements and test cases. Generate a test process according to the test requirements, and complete the test of a complete test case library. This method comprehensively int...
