The invention discloses a hardware-in-loop testing requirement management mode of a new energy vehicle battery management system based on QC. The hardware-in-loop testing requirement management mode is used for conducting hardware-in-loop function testing requirement management of the new energy vehicle battery management system. The method comprises the steps of conducting inputting based on thetesting requirement, tracking the relation of the product function requirement and the testing requirement, tracking the coverage relation between the testing requirement and test cases, and generating a test process according to the testing requirement. The hardware-in-loop testing requirement management mode has the advantages that hardware-in-loop testing of a new energy pure electric vehicle electronic control unit based on the QC is conducted, through a visualized graphical interface, the management of the testing requirement and the use amount between the testing requirement and the testcases is completed, and the hardware-in-loop testing efficiency is improved.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to a QC-based hardware-in-the-loop test demand control method and system for a new energy vehicle battery management system. Background technique [0002] Hardware-in-the-loop is a computer term, that is, hardware-in-the-loop. By using "hardware-in-the-loop" (HiL), development time and costs can be significantly reduced. In the past, the use of computer simulation and actual experimentation have been separated from each other when developing electromechanical components or systems. However, by using a hardware-in-the-loop approach, the two processes can be combined and exhibit a significant increase in efficiency. [0003] At present, hardware-in-the-loop technology is widely used in the V-shaped development process of automotive electronic controller units. It uses a real-time processor to run a simulation model to simulate the operating state of the controlled object, and comm...

Problems solved by technology

However, its high-precision real-time requirements, the safety of high voltage and high current, the special properties of the signal interface, and the scalability of the system all make it impossible for the HiL hardware-in-the-loop simulation test system of the traditional automotive electronic control system to solve the problem.
