In addition, the test system provided by the present application can also set corresponding test parameters for each electric drive controller to be tested, and test multiple electric drive controllers to be tested simultaneously based on the set test parameters, which makes it possible not only to test multiple different electric drive controllers at the same time under multiple identical test parameters, but also to test multiple identical electric drive controllers at the same time under multiple different test parameters, and also to test multiple different electric drive controllers at the same time under multiple different test parameters, so that not only the test differences of various electric drive controllers can be compared more effectively, but also the test efficiency can be improved.

[0046] Figure 1 FIG. 1 is a schematic diagram showing a test system for an electric drive controller according to an exemplary embodiment. Figure 1 As shown, the test system may include a base 101 , a plurality of electric drive controllers to be tested 102 , an environment simulation device 103 , a working condition simulation device 104 and a host computer control system 105 .

[0047] The base 101 is provided with a mounting position for placing the electric drive controller 102 to be tested. In some embodiments, the number of bases 101 may be one or more. In the case where the number of bases 101 is one, the base 101 may be provided with multiple mounting positions, each mounting position being used to place an electric drive controller 102 to be tested. In the case where the number of bases 101 is multiple, such as Figure 1 As shown, each base 101 may be provided with a mounting position, so that a tested electric drive controller 102 is placed on the mounting position of each base 101. In the embodiment of the present application, the base 101 may be provided on the environmental simulation device 103, so that a plurality of tested electric drive controllers 102 are provided on the environmental simulation device 103.

[0048] The electric drive controller 102 to be tested refers to a device used to monitor and control the operating state of the motor. For example, during the operation of the vehicle, the vehicle controller outputs a torque signal according to the current operating state of the vehicle. After receiving the torque signal, the electric drive controller 102 to be tested controls the motor to output the torque value indicated by the torque signal, and the motor transmits the torque to the wheels of the electric vehicle to drive the wheels of the electric vehicle.

[0049] The environmental simulation device 103 is respectively connected to a plurality of electric drive controllers 102 to be tested, and is used to control the environmental parameters during the operation of the plurality of electric drive controllers 102 to be tested, so as to simulate the environmental parameters of the vehicle to be tested corresponding to the electric drive controller 102 to be tested during the operation.

By simulating various working conditions by the working condition simulation device, the performance of the electric drive controller 102 to be tested can be quickly and accurately evaluated in a laboratory environment.

[0051] The host computer control system 105 is provided with a controller, and the controller can be connected to the electric drive controller 102 to be tested, the environmental simulation device 103, and the working condition simulation device 104 through the controller area network (CAN) communication protocol to integrate the complete electric drive controller system through communication integration. The controller can generate simulation instructions based on the test requirements to control the electric drive controller 102 to be tested, the environmental simulation device 103 or the working condition simulation device 104 to run according to the set test parameters, and at the same time, detect and output the test data during the test process.

[0052] The following is based on Figure 1 The test system shown exemplifies the electric drive controller testing process.

[0053] Exemplarily, first, multiple electric drive controllers 102 to be tested are installed on the mounting positions of the base 101 according to the test requirements, and the environmental simulation device 103 and the operating condition simulation device 104 are respectively connected to each electric drive controller 102 to be tested, and at the same time, the host computer controller system 105 is connected to the electric drive controller 102 to be tested, the environmental simulation device 103 and the operating condition simulation device 104 through the CAN communication protocol to ensure that the host computer controller system 105 can send and receive signals normally.

[0054] Subsequently, the test parameters are set in the host computer controller system 105, including environmental parameters, operating parameters, and test time. The host computer controller system 105 generates corresponding simulation instructions according to the test parameters, and sends the simulation instructions to the environment simulation device 103, so that the environment simulation device 103 adjusts environmental parameters such as temperature and humidity according to the simulation instructions. In addition, the host computer controller system 105 also sends the simulation instructions to the operating condition simulation device 104, so that the operating condition simulation device 104 adjusts the load, the flow rate and temperature of the coolant according to the simulation instructions. At the same time, the host computer controller system 105 also sends the simulation instructions to multiple electric drive controllers 102 to be tested, so that the multiple electric drive controllers 102 to be tested are in operation.

[0055] Next, during the test process, the host computer controller system 105 monitors the operating data of the multiple electric drive controllers 102 to be tested in real time, and outputs the test data so that the experimenter can analyze it based on the visualized data.

It can be understood that this method not only reduces the waiting time and makes the test more efficient, but also can more realistically simulate the changes in the environment and working conditions of the electric drive controller to be tested in actual operation.

[0083] As another possible implementation, after obtaining the test parameters corresponding to each electric drive controller to be tested, the environment simulation device can be controlled to reach the set environment parameters and the working condition simulation device can be controlled to reach the set working condition parameters. When the environment simulation device reaches the set environment parameters and the working condition simulation device reaches the set working condition parameters, the electric drive controller to be tested is controlled to run and the electric drive controller to be tested is tested. It can be understood that this method can ensure the reliability and consistency of the test results by stabilizing the environment and working conditions before testing.

[0084] Exemplarily, the operation of the electric drive controller to be tested can be controlled after the actual temperature reaches the set temperature during the operation of the electric drive controller to be tested, the actual coolant flow rate reaches the set flow rate of the coolant flowing through the electric drive controller to be tested, and the actual coolant temperature reaches the set temperature of the coolant flowing through the electric drive controller to be tested.

[0085] Based on S101-S102, the present application provides a test method for an electric drive controller, which can simulate the environmental parameters of the vehicle to be tested corresponding to the electric drive controller to be tested during operation through an environmental simulation device, and simulate various working conditions of the electric drive controller to be tested through a working condition simulation device, so that multiple electric drive controllers to be tested can be tested by setting the environmental parameters, working condition parameters, etc. included in the test parameters. Compared with testing the electric drive controller to be tested by connecting a complete motor, this method not only reduces the test cost, but also improves the test efficiency, without waiting for the development of the complete motor. In addition, the test system provided by the present application can also set corresponding test parameters for each electric drive controller to be tested, and test multiple electric drive controllers to be tested simultaneously based on the set test parameters, which makes it possible not only to test multiple different electric drive controllers to be tested simultaneously under multiple identical test parameters, but also to test multiple identical electric drive controllers to be tested simultaneously under multiple different test parameters, and also to test multiple different electric drive controllers to be tested simultaneously under multiple different test parameters, so that not only the test differences of various electric drive controllers can be compared more effectively, but also the test efficiency can be improved.

[0086] In some embodiments, multiple electric drive controllers to be tested may be placed in the test system, and the multiple electric drive controllers to be tested may be tested, or multiple target electric drive controllers (i.e., the electric drive controllers to be tested in step S101, hereinafter referred to as target electric drive controllers for ease of understanding) may be selected from the multiple electric drive controllers to be tested for testing. Therefore, before step S101, the test method of the electric drive controller provided in the embodiment of the present application further includes the following steps:

[0087] S201: Obtain selection information of a target test channel.

[0088] The target test channel is any one or more of the multiple test channels, one test channel corresponds to one electric drive controller to be tested, and the selection information of the target test channel is used to indicate the selected target electric drive controller.

[0089] As a possible implementation manner, the target test channel may be selected through an operation interface of the controller.

[0090] In some embodiments, after selecting a target test channel, the name of the target test channel may be customized to distinguish between various electric drive controllers to be tested.

[0091] In some embodiments, for an unselected test channel or a test channel without a corresponding electric drive controller to be tested, it is not necessary to record the operation data of the electric drive controller to be tested corresponding to the test channel to avoid recording useless data.

[0092] S202: Acquire information indicating operating data that needs to be collected.

[0093] As a possible implementation method, the operating data that needs to be collected and recorded in real time can be selected in the controller's operating interface, for example, the CAN communication signal of the electric drive controller to be tested corresponding to each test channel, the voltage and current signal output by the electric drive controller to be tested collected by the data synchronization acquisition system, the internal temperature, etc.

[0094] S203: Obtain a display mode for operation data.

[0095] As a possible implementation, the arrangement of the operating data of the multiple electric drive controllers to be tested can be set through the operation interface of the controller. The display time of the operating data of the multiple electric drive controllers to be tested can also be set through the operation interface of the controller. For example, the operating data of the multiple electric drive controllers to be tested can be output in real time during the test process, and the operating data of the multiple electric drive controllers to be tested can also be set to be output uniformly after the test is completed.

[0096] Based on the above S201-S203, the test process and display of test data of multiple electric drive controllers to be tested can be customized, so that the performance differences of various electric drive controllers to be tested can be compared more intuitively and effectively according to actual test requirements.

[0097] In some embodiments, Figure 7 As shown, a test method for an electric drive controller provided in the present application may also include the following steps:

[0098] S301. During the process of testing each electric drive controller to be tested, obtain operation data of each electric drive controller to be tested.

[0099] As a possible implementation method, the operation data of each electric drive controller to be tested can be acquired through a data synchronization acquisition system. For example, the voltage, current signal, internal temperature and other data output by each electric drive controller to be tested can be acquired through various sensors.

[0100] S302: Outputting the operating data of the plurality of electric drive controllers to be tested via a display device.

[0101] As a possible implementation method, the operating data of multiple electric drive controllers to be tested can be displayed on the same display interface of the display device, so that the differences between the multiple electric drive controllers to be tested at a certain moment or the differences between the multiple electric drive controllers to be tested during the entire test process can be compared. In this way, the multiple electric drive controllers to be tested can be compared more effectively to control whether the overall performance of each electric drive controller to be tested meets the design requirements and the differences in performance.

[0102] As another possible implementation, the operating data of the multiple electric drive controllers to be tested may be processed so that the operating data of the multiple electric drive controllers to be tested are outputted in a curve through a display device.

[0103] As another possible implementation, the operating data of multiple electric drive controllers to be tested may be output in real time during the test process, or the operating data of multiple electric drive controllers to be tested may be output uniformly after the test is completed.

[0104] Based on the above S301 - S303 , the operating data of multiple electric drive controllers to be tested can be output in real time through the display device, making the test of the electric drive controller more intuitive and efficient.

[0105] It should be noted that the method shown in the above embodiment can be executed by the host computer control system as a whole, or by a controller in the host computer control system, or by other electronic devices. This application does not specifically limit the execution subject of the method shown in the above embodiment.

[0106] The following is an exemplary description of the complete process of a testing method for an electric drive controller provided in the present application.

[0107] like Figure 8 As shown, the host control system obtains the selection information of the target test channel, obtains the information for indicating the operating data to be collected, and obtains the display mode of the operating data, so as to configure the synchronization comparison parameters based on the obtained information, that is, to execute the above S201-S203. Then, the host control system executes the corresponding program, and controls the load simulation device, the high-voltage battery device, the low-voltage battery device, the cooling system simulation device, the environmental simulation device, and the start and stop of multiple electric drive host control systems to be tested, so as to test multiple electric drive host control systems to be tested. Finally, the host control system stores / displays the operating data of multiple electric drive host control systems to be tested during the test process.
