The invention relates to a driving motor test control method for an electric vehicle, comprising the following steps: developing software based on the automobile bus, writing a communication protocol database file; developing software based on the automobile bus, writing a control test interface for controlling the test of the motor under test; specifying the control test The mapping relationship between the controls in the interface and the variables in the database file; the CAN network simulation model is established based on the communication protocol database file, and unnecessary nodes are shielded; Write programs for each control to realize the functions of each control; for the tested motors of different communication protocols, once the control test interface is written, it does not need to be changed repeatedly. The mapping relationship can realize the test control of different motors under test and display the key state information of the motor under test through the control test interface.
Description
technical field [0001] The invention relates to a test control method for a driving motor used in an electric vehicle. Background technique [0002] In general, the communication protocols of the driving motor systems of different platform models are different, so in the process of driving motor performance testing, the working control methods are also different. Generally, the tested motor control is mostly tested with a test bench. The test method cannot meet the control of the motor system under different communication protocols, and the scalability is poor. In addition, during the test process, the input of key control parameters may cause abnormal operation of the motor under test and even cause safety hazards. Contents of the invention [0003] The invention proposes a driving motor test control method for electric vehicles, which solves the problem that the motor system testing is difficult due to the different communication protocols of the motor systems of new ene...
