The invention discloses a dSPACE-based motor control hardware-in-the-loop automatic test system and method. The system includes a to-be-tested object motor controller, a hardware-in-the-loop simulation platform and an automatic test system platform; the hardware-in-loop simulation platform includes a real-time processor, an IO board card, test management software, and the like, wherein the real-time processor is connected with the to-be-tested motor controller through the IO board card and operates a virtual motor model to simulate the operating state of a motor; and the automatic test platform includes a keyword driving module, a test case editing module, a Robot Framework automatic test framework, a test execution module, and a test report output module. With the dSPACE-based motor control hardware-in-the-loop automatic test system and method of the invention adopted, the logic function of the to-be-tested motor controller can be tested automatically; the strategy response of fault injection can be verified; the startup of the automatic test system can be controlled through command line statements; a test report can be automatically generated; automatic testing can be realized ina real sense; and a sound test process of an enterprise can be established. The automatic test system can be conveniently integrated with an existing open-source Jenkins regression test system.

Description

technical field [0001] The invention relates to a motor controller hardware-in-the-loop automatic test, in particular to a dSPACE-based motor controller hardware-in-the-loop automatic test system and method. Background technique [0002] With the rapid development of new energy vehicles, the motor controller is the core component of new energy vehicles, and the demand for its development and testing environment and system development efficiency is also increasing day by day. The hardware-in-the-loop simulation test based on V mode has been proved to be an effective test method. The real-time processor runs the simulation model of the motor to simulate the running state of the motor, and connects with the motor controller under test through the I / O interface. The motor controller under test is tested comprehensively and systematically. [0003] In the initial stage of project development, the control logic and function verification of the motor controller can be quickly carr...

Problems solved by technology

HIL testing can be realized in two ways. One is to use the graphical user operating environment of ControlDesk developed by dSPACE for manual testing, such as reading the parameters in the real-time model, modifying them, and recording data. Due to the general working condition test steps Many, manual testing is heavy and time-consuming; the second is to use the AutomationDesk graphical interface programming developed by dSPACE to complete the writing of test cases, but a lot of graphical packaging is required in the early stage, and it is limited by the number of software licenses. Poor, and the graphical test case editing process is prone to errors, which greatly reduces the development efficiency of test cases. To judge complex test results, testers need to have a certain programming foundation
