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

Embodiment Construction

[0030] The dSPACE-based motor control hardware-in-the-loop automatic test system of the present invention is connected with the HIL simulation platform, and realizes the closed-loop control of the motor by sending simulation signals through the automation control HIL simulation platform. The automated testing method is based on the open source Robot Framework testing framework. Testers can quickly and agilely develop test cases and automatically generate beautiful test reports. Compared with commercial tool test platforms, the efficiency is increased by at least 50%.

[0031] The test method provided by the present invention can control when to start the HIL automation test through the command line statement, and automatically generate the test report, which is convenient to integrate with the existing open source Jenkins regression test system. Test and establish a complete test process for the enterprise.

[0032] Such as figure 1 As shown, the motor controller hardware-in-...

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 control hardware-in-the-loop automatic test, in particular to a dSPACE-based motor control 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 carried ou...
