The configuration of the vehicle body and motor needs to be determined through power calculations. Generally, a 30KW motor is sufficient to meet the size and load requirements of civilian electric vehicles. Therefore, electric vehicle manufacturers usually use a 30KW motor as standard equipment.

[0003] To ensure that the motor controller does not malfunction after actual vehicle operation, thereby improving the reliability of vehicle driving safety, it is necessary to test the motor controller during the vehicle manufacturing and R&D production process. One testing method is to use a motor test bench to test the motor controller, but this method has low testing efficiency and high bench cost. Another testing method is to use a motor simulator to test the motor controller, but this method has lower voltage levels and testing frequency. Summary of the Invention

[0011] Embodiments of this application also provide a computer-readable storage medium storing a computer program that, when executed by a processor, implements the above-described test method for the motor controller.

[0012] Compared to existing technologies, the motor simulator in this application includes a main control unit and a power control unit, which are connected. The power control unit includes a power component control unit, which can collect a first signal sent by the motor controller to the motor simulator and send the first signal to the main control unit. The main control unit includes a main control model pre-built based on the motor's main controller. By running the main control model, it can simulate the main controller sending control signals to the power control unit. The power supply voltage of the motor simulator is a preset voltage. Therefore, the main control model can output a second control signal based on the preset voltage and the first signal, and send the second control signal to the power control unit. This allows the power control unit to adjust the second control signal and output a third control signal at a preset frequency. That is, the output voltage supplies power to the device, and the third control signal is the output signal of the motor simulator. Therefore, the third control signal can be used to test the motor controller. Since the power supply voltage of the motor simulator is a preset voltage and the output frequency is preset, the voltage level and test frequency can be increased by setting the preset voltage and output frequency values. Furthermore, this application completes the motor controller test by simulating the output of the main controller through a model, which is more efficient than bench testing and saves the cost of bench testing.

[0013] Furthermore, the number of power component control units is N, where N is an integer greater than 0. The rated power of each power component control unit is preset. The motor simulator also includes drive units connected to the main control unit and the power control units respectively. The drive unit includes N drive circuits, and each drive circuit corresponds to one power component control unit. Different drive circuits correspond to different power component control units. The main control unit is specifically used to send the output second control signal to the target drive circuit in the drive unit. The target drive circuit is used to send the second control signal to the power component control unit corresponding to the target drive circuit. In this application, the output signals of N different power component control units are controlled by N different drive circuits, so that the third control signal output by the power component control unit is controllable in real time. At the same time, the power level of the power control unit can be increased by increasing the number of power component control units.

[0014] In addition, the motor simulator also includes feedback units connected to the main control unit and the power control unit respectively; the feedback unit includes M feedback circuits, where M is an integer greater than N, and each power component control unit corresponds to one feedback circuit, with different power component control units 110 corresponding to different feedback circuits; the power component control unit is specifically used to send the collected first signal to the target feedback circuit corresponding to the power component control unit; the target feedback circuit is used to send the first signal to the main control unit.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the various embodiments of this application will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this application to help readers better understand this application. However, the technical solutions claimed in this application can be implemented even without these technical details and various changes and modifications based on the following embodiments. The division of the various embodiments below is for the convenience of description and should not constitute any limitation on the specific implementation of this application. The various embodiments can be combined with and referenced by each other without contradiction.

[0026] To facilitate understanding, the motor simulator is explained as follows:

[0027] A motor simulator is a testing device designed to meet the testing needs of motor controllers in vehicle manufacturing and R&D. It simulates the actual operation of a motor based on the performance of the motor controller. The motor simulator can simulate the actual working state of the motor when the motor controller is operating, serving as a substitute test piece for the motor and providing a technical solution for testing motor controllers without a motor. Furthermore, the motor simulator accurately reflects test results and data, thus clarifying the precise requirements of the motor controller during the design and development phase. It can also simulate different control methods under the same working environment according to customer needs, offering high-end controllable and adjustable performance. Therefore, compared to testing motor controllers using a test bench, the method of using a motor simulator solves the problem of testing motor controllers without a motor under load, offering higher testing efficiency and safety, and eliminating the cost of a test bench.

[0028] However, existing motor simulators in related technologies, such as the Scienlab new energy vehicle motor simulator, have a voltage level of 560V and a frequency within 2.5kHz, which are both relatively low. The motor simulator of this application not only possesses the advantages of traditional motor simulators—high testing efficiency, high safety, and low cost—but also allows for higher voltage levels and testing frequencies when testing motor controllers.

[0029] One embodiment of this application relates to a motor simulator. The implementation details of the motor simulator in this embodiment are described in detail below. The following content is only for the convenience of understanding and is not necessary for implementing this solution.

[0030] The structure of the motor simulator in this embodiment is as follows: Figure 1 As shown, it includes a main control unit 10 and a power control unit 11, wherein the main control unit 10 and the power control unit 11 are connected.

[0031] The main control unit 10 in this embodiment includes a main control model 100, which is pre-built based on the motor's main controller. The main control model 100 is used to send control signals to the power control unit 11 to control the operation of the power control unit 11. The power control unit 11 includes a power component control unit 110, which is used to adjust the control signals sent by the main control model 100 and output the adjusted control signals to supply power to the device. Based on the control signals output by the power component control unit 110 and preset test items, the motor controller can be tested. The control signals can be voltage signals or current signals.

[0032] Specifically, the motor controller controls the operation of the motor simulator. Therefore, the motor controller first sends a control signal, i.e., a first signal, to the motor simulator. The power component control unit 110 in the power control unit 11 can collect the first signal sent by the motor controller to the motor simulator, and then send the first signal to the main control unit 10. This causes the main control model 100 in the main control unit 10 to output a second control signal based on a preset voltage and the first signal, and send the second control signal to the power control unit 11. The preset voltage is determined by the power supply connected to the motor simulator in this embodiment, for example, a preset voltage of 900V. The power component control unit 110 can adjust the second control signal to obtain a third control signal, and output the third control signal at a preset frequency, which can be 5kHz. Therefore, the motor controller can be tested based on the third control signal output by the power component control unit 110 and the preset test items.

[0033] In one example, the specific testing can be performed by the host computer. That is, control signals are sent to the host computer simultaneously with the input to the corresponding device. Preset test items are stored in the host computer, enabling it to complete the motor controller test. Alternatively, the motor controller test can be performed by clicking on a component in the simulator; in this case, the preset test items are stored in the motor simulator. These preset test items can be a processed standard control signal output by the motor simulator based on the control signals sent by the motor controller to the simulator under standard conditions. The host computer or the motor simulator itself compares the third control signal with the standard control signal to complete the motor controller test.

[0034] In one example, the structure of the power component control unit 110 is as follows: Figure 2 As shown, the system includes an analog component and a three-phase interface. The analog component is used to acquire the first signal sent by the motor controller to the motor simulator and send the first signal to the main control unit 10. It also adjusts the second control signal sent by the main control unit 10 to obtain a third control signal and outputs the third control signal at a preset frequency. The power component control unit 110 is connected to the motor controller through the three-phase interface. Therefore, the power component control unit 110 can acquire the first signal sent by the motor controller to the motor simulator through the three-phase interface to improve the communication rate between the power component control unit and the motor controller. The power control unit 11 includes an optical module (Small Form Pluggable, SFP interface). The power control unit 11 is connected to the main control unit 10 through the SFP interface. Therefore, the power control unit 11 sends the acquired first signal to the main control unit 10 through the SFP interface to improve the communication rate between the power control unit and the main control unit. The rated power of the power component control unit 110 is preset, for example, the rated power is ≤30KW. The effective range of the phase current and phase voltage measurement values ​​of the power component control unit 110 is also preset, for example, the effective range of the phase current measurement value is -150A to 150A, and the effective range of the phase voltage measurement value is 0 to 1000V.

[0035] It should be noted that the communication interface between the power control unit 11 and the main control unit 10 also includes: an RS-485 interface, a Controller Area Network (CAN) interface, and a Local Area Network (LAN) interface. That is, in this embodiment, the power control unit 11 and the main control unit 10 can also communicate through the above interfaces. The CAN interface includes both CAN 2.0B and CAN-FD interfaces. Additionally, the motor simulation circuit in this embodiment may also include auxiliary circuits, such as a control interface circuit.

[0036] In this embodiment, the motor simulator includes a main control unit and a power control unit, which are connected. The power control unit includes a power component control unit, which can collect a first signal sent by the motor controller to the motor simulator and send the first signal to the main control unit. The main control unit includes a main control model pre-built based on the motor's main controller. By running the main control model, the main controller can simulate sending control signals to the power control unit. The power supply voltage of the motor simulator is a preset voltage. Therefore, the main control model can output a second control signal based on the preset voltage and the first signal, and send the second control signal to the power control unit. This allows the power control unit to adjust the second control signal and output a third control signal at a preset frequency. That is, the output voltage supplies power to the device, and the third control signal is the output signal of the motor simulator. Therefore, the third control signal can be used to test the motor controller. Since the power supply voltage of the motor simulator is a preset voltage and the output frequency is preset, the voltage level and test frequency can be increased by setting the preset voltage and output frequency values. Furthermore, this application uses a model to simulate the output of the main controller to complete the test of the motor controller, which is more efficient than bench testing and saves the cost of bench testing.

[0037] In one embodiment, the number of power component control units 110 is N, where N is an integer greater than two. The motor simulator also includes a drive unit 12 connected to the main control unit 10 and the power control unit 110 respectively. The drive unit 12 includes N drive circuits 120, each drive circuit 120 corresponding to one power component control unit 110. Different drive circuits 120 correspond to different power component control units 110. The structure of the motor simulator in this embodiment is as follows: Figure 3 As shown.

[0038] Specifically, the main control unit 10 is used to send the output second control signal to the target drive circuit 120 in the drive unit 12. The target drive circuit 120 is used to send the second control signal to the power component control unit 110 corresponding to the target drive circuit 120. That is, in this embodiment, by setting the drive unit 12, the main control unit 10 sends the second control signal to the power control unit through the drive unit 12. The drive unit 12 includes N drive circuits 120. Therefore, the main control unit 10 can control the output signals of different power component control units 110 through different drive circuits 120, so that the output third control signal of the power component control unit 110 is controllable in real time. It can be understood that the rated power of each power component control unit 110 is preset. If the rated power of each power component control unit 110 is 30KW and N=3, then the rated power of the power control unit is 30KW. The number of power component control units 110 can be set according to actual needs. Therefore, the power level of the power control unit 11 can be increased by increasing the number of power component control units 110. It should also be noted that the power of the power component control unit 110 can be flexibly set according to actual needs. Therefore, the sampling rate of the first signal and the output frequency of the third control signal of the power component control unit 110 will change accordingly.

[0039] In one example, the motor simulator also includes a feedback unit 13 connected to the main control unit 10 and the power control unit 11, respectively. The power control unit 11 transmits the first signal acquired by the motor controller to the motor simulator to the main control unit 10 through the feedback unit 13. The feedback unit 13 includes M feedback circuits 130, where M is an integer greater than N, and each power component control unit 110 has a corresponding feedback circuit 130. Different feedback circuits 130 correspond to different power component control units 110. The remaining feedback circuits 130 are used to acquire other signals from the motor simulator, see details below. Figure 3 .

[0040] Specifically, the power component control unit 110 is used to send the acquired first signal to the target feedback circuit 130 corresponding to the power component control unit 110, and the target feedback circuit 130 is used to send the first signal to the main control unit 10. That is, in this embodiment, by setting the feedback unit 13, the power control unit 11 sends the acquired first signal to the main control unit 10 through the feedback unit 13, and the feedback unit 13 includes N feedback circuits 130. Therefore, in this embodiment, the first signals sent by different power component control units 110 can be received through different feedback circuits 130 to achieve individual control of different power component control units 110. Each feedback circuit 130 includes a sensor to realize the reception and feedback of the first signal.

[0041] In the specific implementation, the power component control units 110 are connected via a DC bus. If the preset voltage is 900V, the DC bus voltage is 900V. The DC bus also includes a DC bleed resistor, a DC-to-ground bleed resistor, a bleed relay, and an absorption capacitor (not shown in the figure). The ripple current of the DC bus is calculated using the Space Vector Pulse Width Modulation (SVPWM) algorithm. The formula for calculating the ripple current is:

[0042]

[0043] Among them, I CRMS I represents the ripple current. c t represents the total current of the power control unit 11, and t represents the working time of the motor simulator.

[0044] In one example, the motor simulator has 3 power component control units 110, 3 drive circuits 120, and 3 feedback circuits 130. The preset voltage is 900V, the rated power of the power control unit is 30KW, the preset frequency is 5KHZ, the effective range for measuring the phase current value of the power component control unit 110 is -150A to 150A, and the effective range for measuring the phase voltage value is 0 to 1000V. Thus, the voltage level of the motor simulator has been increased from 540V in related technologies to 900V, and the test frequency has been increased from 2.5KHZ to 5KHZ.

[0045] In this embodiment, different feedback circuits receive the first signals sent by different power component control units to achieve individual control of different power component control units. Different drive circuits control the output signals of different power component control units 110, so that the third control signal output by the power component control unit is controllable in real time. That is, the motor simulator can flexibly output control signals as needed. Therefore, this embodiment is highly consistent with the real-time working state of the motor.

[0052] Step 403: Adjust the second control signal to obtain the third control signal, and output the third control signal at a preset frequency; wherein, the third control signal is used to test the motor controller.

The third control signal is used to test the motor controller. Since the power supply voltage of the motor simulator is a preset voltage and the output frequency is preset, the voltage level and test frequency can be increased by setting the preset voltage and output frequency values. Furthermore, the test method for the motor controller in this application is more efficient than bench testing and saves the cost of bench testing.
