[0037] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.
[0038] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.
[0039] In order to shorten the development cycle of vehicle thermal management systems, simulation methods are generally used in the early stages of design to simulate the status of components for design verification, discover product defects in advance, and avoid them in the early stages of design to reduce the need for later changes to components. When testing the thermal management system of the entire vehicle, the suppliers of each controller need to have corresponding simulation capabilities and provide data simulation models of the controllers for the construction of the overall simulation system. However, the cost of building a controller simulation model is high and time-consuming, which is not conducive to product development.
[0040] In order to solve the above problems, the present disclosure provides a test system for a thermal management system. Figure 1 A schematic diagram of a thermal management system test system provided by an embodiment of the present disclosure, referring to Figure 1 The test system includes: a simulation system 10 and a controller 20.
[0041] The simulation system 10 constructs a thermal management system simulation model; the simulation system 10 is connected to the controller 20 .
[0042] The simulation system 10 is used to send the working parameters of the thermal management system simulation model to the controller 20; the controller 20 is used to generate control instructions according to the working parameters and send them to the simulation system 10, so that the simulation system 10 adjusts the working parameters of the thermal management system simulation model according to the control instructions.
[0043] Exemplarily, the simulation system 10 constructs a thermal management system simulation model, for example, a coupling software is developed in a computer using a software programming language to construct a thermal management system simulation model to simulate the thermal management system of the vehicle. In the subsequent testing process, there is no need to carry a physical thermal management system, and the requirements for equipment and environment are relatively low. Among them, the thermal management system simulation model may include an air-conditioning system model, a cooling system model, a power system model, various heat exchange components of the control system, and electrical component models, and other simulation models associated with the vehicle thermal management system. Based on the above simulation models, various test data such as the power consumption of each electrical appliance in the thermal management system, the energy consumption of the air conditioner, the performance of the air conditioner, the power consumption of the cooling system, and the battery power consumption can be obtained. It should be noted that the embodiment of the present disclosure does not limit the specific content of the model, and it can be set according to actual needs.
[0044] During the test, the thermal management system simulation model will output corresponding working parameters, and the simulation system 10 will send the working parameters to the controller 20. The controller 20 is connected to the simulation system 10, and the controller 20 is a physical hardware structure. The controller 20 generates a control instruction according to the received working parameters and sends it to the simulation system 10, so that the simulation system 10 adjusts the working parameters of the thermal management system simulation model according to the control instruction.
[0045] The thermal management system simulation model constructed by the physical controller 20 and the simulation system 10 is used for testing, and there is no need to construct a simulation model of the controller 20. In the prior art, the simulation model of the controller 20 needs to be provided by the supplier of the controller 20. Usually, the construction and development cycle of the simulation model of the controller 20 is too long, the cost is high, and it is difficult to obtain from the supplier. However, the embodiment of the present disclosure does not require a simulation model of the controller 20, and directly uses the physical controller 20, which greatly saves the cycle and cost of constructing the controller simulation model, and is more conducive to the development of the whole vehicle. Because the thermal management system simulation model is used, when testing under different working conditions, various application scenarios can be simulated through simulation, and there is no need to operate under actual working conditions. Therefore, the requirements for the test environment are relatively low.
[0046] The following explanation is given by taking the cooling performance of the vehicle fast charging process as an example.
[0047] When the vehicle is fast charging, the battery will heat up. To prevent the battery temperature from being too high and affecting the charging efficiency, the thermal management system will perform a cooling operation to reduce the battery temperature to the required target temperature.
[0048] First, control the operation of the thermal management system simulation model to simulate the fast charging state of the whole vehicle. The thermal management system simulation model can obtain a variety of working parameters, such as battery temperature, as well as ambient temperature, air conditioning system heat dissipation, ventilation temperature and other parameters that affect the battery temperature. The simulation system 10 will send the obtained working parameters to the controller 20. The controller 20 generates a control instruction based on the obtained working parameters and combines the target temperature required during the test process and sends it to the simulation system 10. For example, if the current battery temperature is higher than the target temperature, the controller 20 generates a control instruction and sends it to the simulation system 10, so that the simulation system 10 adjusts the working parameters of the thermal management system simulation model according to the control instruction, thereby achieving the purpose of cooling. The above operations are subsequently performed in a loop until the test process ends. The tester can obtain various test data based on the various test data obtained during the entire test process, such as the power consumption of each electrical appliance in the thermal management system, the air conditioning cooling system capacity, and the theoretical battery power consumption under various environmental conditions after completing the test and all calculation processes. Based on the above test data, the working condition and working performance of the vehicle's thermal management system can be verified, and if there are defects in the thermal management system, the design can be adjusted in time.
[0049] It should be noted that the above is only an optional implementation. The embodiment of the present disclosure can test the thermal management system of the vehicle under different working conditions, and the embodiment of the present disclosure does not limit this.
[0050] In the test system of the thermal management system provided by the present disclosure, the controller is connected to the simulation system, the controller is physical hardware, and the controller and the simulation model can exchange information. For example, the working parameters generated by the simulation system during the simulation process can be sent to the controller, and the controller can also generate control instructions based on the working parameters and send them to the simulation system, so that the simulation system adjusts the working parameters of the thermal management system simulation model according to the control instructions to complete the test process. The embodiment of the present disclosure combines the simulation model of the thermal management system with the physical controller during the test process, without the need to develop a controller model, reducing the development cycle and cost, and is applicable to a variety of test scenarios.
[0051] In some embodiments, Figure 2 A schematic diagram of a thermal management system test system according to an embodiment of the present disclosure is provided. Figure 2 , the test system also includes: a data converter 30.
[0052] The data converter 30 is electrically connected to the simulation system 10 and the controller 20 respectively; the data converter 30 is used to convert the signal types of the working parameters and the control instructions.
[0053] Exemplarily, since data needs to be transmitted between the simulation system 10 and the controller 20, and the communication interface between the simulation system 10 and the controller 20 is usually quite different, the two cannot be directly connected for communication. Therefore, a data converter 30 is also provided in the test system, and the signal type of the working parameters and the control instructions is converted by the data converter 30. One end of the data converter 30 is electrically connected to the simulation system 10, and the other end is electrically connected to the controller 20. The simulation system 10 sends the working parameters of the thermal management system simulation model to the data converter 30, and the data converter 30 converts the signal type of the working parameters, and the data converter 30 transmits the converted working parameters to the controller 20. Similarly, the control instructions generated by the controller 20 are also sent to the data converter 30, and the data converter 30 converts the signal type of the control instructions, and the data converter 30 transmits the converted control instructions to the simulation system 10. Therefore, by setting the data converter 30, it is possible to ensure that the data transmission between the simulation system 10 and the controller 20 is not limited by the type of the communication interface.
[0054] In some embodiments, Figure 3 A schematic diagram of a thermal management system test system according to an embodiment of the present disclosure is provided. Figure 2 The data converter 30 includes: a first interface 31, a data processing unit 33 and a second interface 32; the first interface 31 and the second interface 32 are of different types.
[0055] The data converter 30 is electrically connected to the simulation system 10 via the first interface 31; the data converter 30 is electrically connected to the controller 20 via the second interface 32; the first interface 31 is connected to the second interface 32 via the data processing unit 33; the data processing unit 33 is used to convert the signal type of the working parameters and control instructions.
[0056] Exemplarily, when the simulation system 10 needs to transmit the working parameters to the controller 20, the simulation system 10 will first transmit the working parameters to the data converter 30, and the data converter 30 is electrically connected to the simulation system 10 through the first interface 31, and then the working parameters are transmitted to the data processing unit 33 through the first interface 31, and the signal type of the working parameters is converted at the data processing unit 33, and then the converted working parameters are transmitted to the controller 20 through the second interface 32, completing the information transmission between the simulation system 10 and the controller 20. Similarly, the controller 20 outputs control instructions to the simulation system, and the control instructions can also be converted into signal types in the data processing unit 33 after passing through the second interface 32, and then sent to the simulation system.
[0057] In some embodiments, continue to refer to Figure 3The first interface 31 communicates with the data processing unit 33 via a serial port; the second interface 32 communicates with the data processing unit 33 via a LIN bus.
[0058] Exemplarily, the simulation system 10 is a computer, and data is transmitted through a USB (Universal Serial Bus) communication interface, while the controller 20 transmits data through a LIN (Local Interconnect Network, a low-cost serial communication protocol) communication interface. Among them, the LIN signal network is composed of a host node and a plurality of slave nodes, and has strong expansibility. Therefore, the USB signal received by the data converter 30 is converted into a serial port signal through the first interface 31, and the first interface 31 communicates with the data processing unit 33 through the serial port. The first interface 31 is connected to the second interface 32 through the data processing unit 33. In the data processing unit 33, the serial port signal can be converted into a LIN signal, and then the LIN signal is transmitted to the controller 20 through the second interface 32, completing the information transmission between the simulation system 10 and the controller 20. Similarly, when the controller 20 transmits the working parameters to the simulation system 10, the LIN signal received from the second interface 32 is also converted into a serial port signal by the data processing unit 33, and transmitted to the simulation system 10 through the first interface 31.
[0059] It should be noted that the embodiments of the present disclosure do not impose specific restrictions on signal types and interface types. The signal type can be selected according to actual needs, and the corresponding interface type can be selected according to the actual signal types of the simulation system and the controller.
[0060] In some embodiments, continue to refer to Figure 3 The controller 20 includes a plurality of sub-controllers, and different sub-controllers correspond to and control vehicle devices with different functions.
[0061] Exemplarily, the controller 20 includes multiple sub-controllers such as sub-controller A, sub-controller B, and sub-controller C, and different sub-controllers control vehicle components with different functions. For example, sub-controller A controls the vehicle's air-conditioning system, sub-controller B may work the vehicle's compressor, sub-controller C controls the vehicle's power system, and so on. Sub-controllers with different functions control different vehicle components according to the received working parameters. Therefore, during the test process, it is possible to quickly determine whether a sub-controller has a fault, and whether the vehicle component controlled by the sub-controller is improperly selected, so as to facilitate targeted debugging in the later stage.
[0062] Optionally, each sub-controller may also be integrated into a master controller, which may be selected based on the actual structure, and the embodiments of the present disclosure do not impose any restrictions on this.
[0063] In some embodiments, continue to refer to Figure 3 The second interface 32 includes a plurality of sub-interfaces, and the sub-interfaces are electrically connected to the sub-controllers one by one through wiring harnesses.
[0064] Based on the structure of setting multiple sub-controllers, each sub-controller needs to be electrically connected to the data converter 30 to convert the signal. Therefore, the second interface 32 also includes multiple sub-interfaces, each sub-interface is electrically connected to the sub-controller in a one-to-one correspondence, and is used to transmit the data signal received or sent by the corresponding sub-controller. Among them, the sub-interface and the sub-controller can be connected through a wiring harness to meet the circuit design.
[0065] The present disclosure also provides a method for testing a thermal management system. Figure 4 A flow chart of a method for testing a thermal management system provided by an embodiment of the present disclosure is provided. Figure 4 , including S110-S120:
[0066] S110, obtaining working parameters of a thermal management system simulation model of the simulation system.
[0067] The simulation system builds a thermal management system simulation model. For example, a software programming language is used in a computer to develop coupling software to build a thermal management system simulation model to simulate the vehicle's thermal management system. The controller can use a physical hardware structure to reduce the development cycle of building the controller model. The simulation system is connected to the controller to simulate the working conditions of the thermal management system of the entire vehicle. During the test, the two will simulate the working process of the vehicle under different working conditions. The thermal management system simulation model will output the corresponding working parameters, and the controller needs to obtain the working parameters of the thermal management system simulation model of the simulation system, and then perform subsequent operations based on the obtained working parameters in order to continue testing.
[0068] S120, generating a control instruction according to the working parameters and sending the control instruction to the simulation system, so that the simulation system adjusts the working parameters of the thermal management system simulation model according to the control instruction.
[0069] After receiving the working parameters, the controller will make certain adjustments to the current working state of the thermal management simulation model according to the working parameters, such as increasing or decreasing the air conditioning temperature. At this time, the controller will generate corresponding control instructions and send them to the simulation system, so that the simulation system adjusts the working parameters of the thermal management system simulation model according to the control instructions. Based on this, the controller will loop the above operations until the test is completed.
[0070] The disclosed embodiment combines the simulation model of the thermal management system with the physical controller during the test process, eliminating the need to develop a controller model, reducing development cycle and cost, and is applicable to a variety of test scenarios.
[0071] In some embodiments, obtaining the operating parameters of the thermal management system simulation model of the simulation system includes:
[0072] Get the working parameters of the data converter after signal conversion.
[0073] The operating parameters are operating parameters of a thermal management system simulation model of the simulation system.
[0074] For example, since data needs to be transmitted between the simulation system and the controller, and the communication interface between the simulation system and the controller is usually quite different, the types of data signals received and sent by the simulation system and the controller are different, and the controller cannot directly obtain the working parameters of the thermal management system simulation model of the simulation system. In order to solve this problem, the working parameters of the thermal management system simulation model are converted through a data converter, and the controller and the data converter can directly transmit data, and then the controller can obtain the working parameters converted by the data converter, thereby realizing data transmission between the simulation system and the controller.
[0075] The present disclosure also provides a method for testing a thermal management system. Figure 5 A flow chart of another method for testing a thermal management system provided by an embodiment of the present disclosure is provided. Figure 5 , including S210-S220:
[0076] S210: Sending operating parameters of the thermal management system simulation model to the controller.
[0077] The simulation system is connected to the controller, and can simulate the working condition of the thermal management system of the whole vehicle. The simulation system has built a thermal management system simulation model. During the test, the thermal management system simulation model will output the corresponding working parameters, and the simulation system will send these working parameters to the controller to continue the test. For example, the cooling performance of the whole vehicle during the fast charging process is tested. During the fast charging process of the vehicle, the battery will heat up. In order to avoid the battery temperature being too high and affecting the charging efficiency, the thermal management system will perform a cooling operation to reduce the battery temperature to the required target temperature. Control the operation of the thermal management system simulation model to simulate the fast charging state of the whole vehicle. The thermal management system simulation model can obtain a variety of working parameters, such as battery temperature, as well as ambient temperature, air conditioning system heat dissipation, ventilation temperature and other parameters that affect the battery temperature. The simulation system will send the obtained working parameters to the controller.
[0078] S220, accepting a control instruction generated by the controller according to the working parameters, and adjusting the working parameters of the thermal management system simulation model according to the control instruction.
[0079] The controller will generate control instructions based on the obtained working parameters, and the simulation model of the thermal management system of the simulation system needs to accept the control instructions fed back by the controller and adjust its own working parameters during the test according to the control instructions. For example, if the control instruction received is to lower the air-conditioning temperature, the thermal management system control model will adjust the corresponding working parameters according to the control instruction to lower the control temperature and achieve the purpose of cooling. Testers can verify the working condition of the vehicle's thermal management system based on the various test data obtained during the entire test process, and can make timely design adjustments if there are problems with the thermal management system.
[0080] In some embodiments, before sending the operating parameters of the thermal management system simulation model to the controller, the method further includes:
[0081] Build a simulation model of a vehicle's thermal management system.
[0082] Exemplarily, the test system provided by the embodiment of the present disclosure combines the simulation model of the thermal management system with the physical controller. Therefore, before sending the working parameters of the thermal management system simulation model to the controller, it is also necessary to build a simulation model of the vehicle's thermal management system to facilitate the subsequent testing of the thermal management system of the entire vehicle. Among them, the simulation model of the thermal management system can be constructed by performing related operations in a computer. For example, a coupling software is developed using a software programming language to construct a thermal management system simulation model to simulate the thermal management system of the vehicle. According to the working logic of the devices with different functions in the actual vehicle thermal management system, an equivalent simulation design is performed to construct a simulation model.
[0083] Among them, the thermal management system simulation model may include various simulation models associated with the vehicle thermal management system, such as the air conditioning system model, the cooling system model, the power system model, the heat exchange components of the control system, and the electrical component models. Through the simulation model, various test data such as the power consumption of various electrical appliances in the thermal management system, the air conditioning energy consumption, the air conditioning performance, the cooling system power consumption, and the battery power consumption can be obtained. It should be noted that the embodiments of the present disclosure do not limit the specific process of constructing the simulation model and the test data that can be obtained, and can be set according to actual needs.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
