The invention relates to a driving motor test control method for an electric automobile, comprising steps of compiling a communication protocol database file based on automobile bus development software, compiling a control test interface for controlling motor test based on the automobile bus development software, assigning a mapping relation between control members in the control test interface and variables in the database file, establishing a CAN network simulation model based on the communication protocol database file, shielding the nodes that are not in need, and programming for all the control members in the control test interface in order to realize the functions of all the control members based on the automobile bus development software in the CAN network simulation model. According to the invention, for to-be-tested motors of different communication protocols, as soon as the programming of the control test interfaces are completed, the repeated alteration is not needed, and the test control over different to-be-tested motors and key state information display of the to-be-tested motors can be realized through the control test interfaces merely by reestablishing the mapping relation between the control members in the control test interface and the variables in the communication protocol database.
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...
