Description

[Technical Field]

[0001] The present invention relates to a simulator that simulates an input or output device of a test object in order to test the test object. [Background technology]

[0002] In order to test a test object, a simulator that simulates an input device or an output device of the test object is known. As an example of such a simulator, for example, Patent Document 1 discloses a test system for testing a thermal management system that manages heat generated from one or more heat source components of a vehicle.

[0003] The test system includes a simulated vehicle body that simulates the body of a vehicle, a simulated heat source body that is installed inside the simulated vehicle body and that thermally simulates heat source components, a heat supply device that supplies heat to the simulated heat source body, a heat quantity calculation unit that calculates the amount of heat generated from the heat source components of the vehicle while it is running based on a vehicle model that models the vehicle, and a heat source body control unit that controls the heat supply device based on the calculated heat quantity and causes the simulated heat source body to thermally simulate the heat source components.

[0004] This makes it possible to evaluate the thermal management system even before a vehicle prototype is available, shortening the vehicle development period. Furthermore, since evaluation tests of the thermal management system can be performed by simulating the vehicle's surrounding environment before the vehicle prototype is completed, it is also possible to shorten the testing time after the actual vehicle is completed. Furthermore, it makes it possible to evaluate the efficiency of the thermal management system in its system state, measuring the system's electricity consumption and using this as basic data when finalizing vehicle specifications. Furthermore, since driving conditions can be simulated without actually driving on the road, the durability and reliability of parts and systems, as well as the reproducibility of malfunctions, can be safely performed in a test room.

[0005] [Patent Document 1] International Publication No. 2023 / 286656 Summary of the Invention [Problem to be solved by the invention]

[0006] In the test system of Patent Document 1, a heat supply device is controlled and a heat source component is thermally simulated by a simulated heat source. When the heat source component is thermally simulated by the simulated heat source in this way, not only is the simulated heat source necessary, but also power is required to heat the simulated heat source.

[0007] Meanwhile, in test equipment for testing the performance of automotive parts, the input or output device used to test the automotive part under test may be configured with a simulator such as a motor simulator, an inverter simulator, or a battery simulator, which respectively simulate a motor, an inverter, or a battery. In such test equipment, the simulator simulates characteristics other than heat to test the performance of the part under test. In recent years, there has been a demand for a configuration that can also simulate heat generated by the simulated devices, such as the motor, inverter, or battery.

[0008] An object of the present invention is to provide a simulator that can simulate not only the characteristics of a simulated device used in a performance test, but also the heat generated in the simulated device. [Means for solving the problem]

[0009] A simulator according to one embodiment of the present invention simulates an input device or an output device for a test subject to test the test subject. The simulator includes a test subject test simulator section that simulates the input device or the output device to test the test subject, a heat generation simulator section that uses heat generation in the test subject test simulator section to simulate heat generation in the input device or the output device, and a control section that controls the operation of the heat generation simulator section in accordance with the operation of the test subject test simulator section (first configuration).

[0010] This makes it possible to simulate the heat generated in the input or output device by utilizing the heat generated in the test unit simulation section that simulates the input or output device and tests the test unit, thereby eliminating the need to supply power to simulate the heat generated in the input or output device.

[0011] Furthermore, the control unit can control the driving of the heat generation simulation unit that simulates the heat generation in accordance with the operation of the specimen test simulation unit, thereby driving the heat generation simulation unit in accordance with the operation of the specimen test simulation unit.

[0012] Therefore, it is possible to realize a simulator that can simulate not only the characteristics of a simulated device used in a performance test, but also the heat generated in the simulated device.

[0013] In the first configuration, the control unit controls the driving of the specimen test simulation unit in addition to the heat generation simulation unit (second configuration).

[0014] This allows the control unit to control the driving of both the heat generation simulation unit and the specimen test simulation unit. Therefore, the driving of the heat generation simulation unit and the specimen test simulation unit can be controlled in an integrated manner. Therefore, the heat generation simulation unit can be driven more accurately in accordance with the operation of the specimen test simulation unit.

[0015] In the first configuration, the heat generation simulation unit has a heat generation assistance unit that is driven and controlled by the control unit and generates heat to assist in simulating the heat generation of the input side device or the output side device (third configuration).

[0016] This allows the auxiliary heat generating unit to assist in simulating the heat generated by the input device or the output device. Therefore, even if the heat generated by the specimen test simulation unit alone is insufficient, the auxiliary heat generating unit can make up for the lack of heat. Therefore, the simulator can accurately simulate the heat generated by the input device or the output device.

[0017] In the first configuration, the heat generation simulation section has a heat exchange section for recovering heat generated in the specimen test simulation section (fourth configuration).

[0018] This allows the heat generation simulation section to efficiently recover the heat generated in the specimen test simulation section using the heat exchanger. Therefore, by utilizing the recovered heat, the simulation device can simulate the heat generation of the input side device or the output side device with minimal power consumption.

[0019] In the fourth configuration, the heat generation simulation section includes a cooling section that cools the heat exchange section so as to simulate heat generation from the input side device or the output side device (fifth configuration).

[0020] As a result, if the amount of heat generated in the specimen test simulation section is greater than the amount of heat generated by the input device or the output device, the cooling section can cool the heat exchanger to match the amount of heat generated by the input device or the output device, thereby allowing the simulation device to more accurately simulate the heat generated by the input device or the output device. [Effects of the Invention]

[0021] A simulation device according to one embodiment of the present invention comprises a specimen test simulation unit that simulates an input device or an output device and tests a specimen, a heat generation simulation unit that uses heat generation in the specimen test simulation unit to simulate heat generation in the input device or the output device, and a control unit that controls the operation of the heat generation simulation unit in accordance with the operation of the specimen test simulation unit.

[0022] This allows the heat generation simulation unit to be driven in response to the operation of the test unit without supplying power to simulate the heat generation in the input device or the output device, thereby realizing a simulation device that can simulate not only the characteristics of the target device used in the performance test but also the heat generation generated in the target device. [Brief explanation of the drawings]

[0023] [Figure 1] FIG. 1 is a functional block diagram showing a schematic configuration of a simulation device according to an embodiment. [Figure 2] FIG. 2 is a functional block diagram illustrating an example of the configuration of the simulator. [Figure 3] FIG. 3 is a functional block diagram showing a schematic configuration of the temperature control unit. DETAILED DESCRIPTION OF THE INVENTION

[0024] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the accompanying drawings. In the drawings, the same or corresponding parts are designated by the same reference numerals and the description thereof will not be repeated.

[0025] (Overall composition) FIG. 1 is a diagram showing a schematic configuration of a simulator 1 according to an embodiment of the present invention. This simulator 1 is a device that simulates an input device or an output device for a test object M when testing the test object M. The test of the test object M includes an operation test or a characteristic confirmation test of the test object M. The test object M includes, for example, an inverter device, a motor, a battery, etc. The simulator 1 includes, for example, a battery simulator, an inverter simulator, a motor simulator, etc. The test object M and the simulator 1 may include other configurations.

[0026] The input device is a device that inputs energy (torque, current, voltage, etc.) to the specimen M. The output device is a device that outputs energy (torque, current, voltage, etc.) from the specimen M. If the specimen M is, for example, an inverter device, the input device is a battery device. If the specimen M is, for example, a motor, the input device is an inverter device, and the output device is a dynamo for the motor load. If the specimen M is a battery, the output device is an inverter device.

[0027] The simulator 1 includes a specimen test simulation unit 10, a control unit 20, and a heat generation simulation unit 30.

[0028] The specimen test simulation unit 10 simulates an input side device or an output side device for the specimen M in order to test the specimen M. The configuration of the specimen test simulation unit 10 is the same as that of a conventional one, so a detailed description will be omitted. In this embodiment, an example will be described in which the specimen M is an inverter device and the specimen test simulation unit 10 is a battery simulation device. That is, in this embodiment, an example will be described in which the specimen test simulation unit 10 simulates the input side device of the specimen M.

[0029] The specimen test simulation unit 10 generates heat due to the operation of its internal components when simulating an input device or an output device for the specimen M. In this embodiment, the specimen test simulation unit 10 is a battery simulation device, and heat is generated due to the operation of multiple switching elements that perform operations to simulate a battery device. The heat generated in the specimen test simulation unit 10 is transferred to the heat exchange unit 31 of the heat generation simulation unit 30, which will be described later.

[0030] The heat generation simulation unit 30 simulates heat generation in the device simulated by the specimen test simulation unit 10. In this embodiment, since the specimen test simulation unit 10 simulates a battery device, the heat generation simulation unit 30 simulates heat generation in the battery device. The heat generation simulation unit 30 simulates heat generation in the battery device, for example, by utilizing heat generated when the specimen test simulation unit 10 simulates the battery device. The heat generation simulation unit 30 is configured to be driven and controlled by the control unit 20, which will be described later, to simulate heat generation in accordance with the operation of the device simulated by the specimen test simulation unit 10.

[0031] The heat generation simulation unit 30 includes a heat exchange unit 31 , an auxiliary heat generation unit 32 , and a cooling unit 33 .

[0032] The heat exchanger 31 recovers the heat generated by the specimen test simulation unit 10. The heat exchanger 31 is, for example, a heat exchanger. The heat recovered by the heat exchanger 31 is supplied to the specimen-side thermal management device MH. The specimen-side thermal management device MH is a thermal management device that is tested together with the specimen M, and is used to test the cooling structure of the specimen using the heat quantity simulated by the heat generation simulation unit 30, and to consider the effective use of the heat quantity.

[0033] The configuration for recovering the heat generated in the specimen test simulation section 10 by the heat exchange section 31 will be described later.

[0034] The auxiliary heat generating unit 32 generates heat to supplement the heat amount when the amount of heat recovered by the heat exchange unit 31 is not enough to simulate the heat generated in response to the operation of the device simulated by the specimen test simulation unit 10. The auxiliary heat generating unit 32 is, for example, a heater. When the amount of heat recovered by the heat exchange unit 31 is greater than the amount of heat generated when the device simulated by the specimen test simulation unit 10 is in operation, the cooling unit 33 cools the heat exchange unit 31 so as to reduce the amount of heat recovered by the heat exchange unit 31. The cooling unit 33 is, for example, a fan or a cooling element (e.g., a Peltier element).

[0035] The heat generation simulation unit 30 may have a casing that is capable of conducting heat from the heat exchange unit 31 and the auxiliary heat generation unit 32. The casing preferably has the same thermal conductivity as the casing of the device whose heat generation is simulated by the heat generation simulation unit 30. The casing may be configured to conduct heat to the specimen-side thermal management unit MH.

[0036] The control unit 20 controls the operation of the specimen test simulation unit 10 and the operation of the heat generation simulation unit 30. The control unit 20 controls the operation of the specimen test simulation unit 10 so that the specimen test simulation unit 10 simulates the input side device or the output side device. The control unit 20 controls the operation of the heat generation simulation unit 30 so that the heat generation simulation unit 30 simulates the heat generation of the device simulated by the specimen test simulation unit 10. In this embodiment, the control unit 20 controls the operation of the plurality of switching elements in the specimen test simulation unit 10, thereby causing the specimen test simulation unit 10 to simulate a battery device. The control unit 20 also causes the heat generation simulation unit 30 to simulate the heat generation when the battery simulation device is operating.

[0037] More specifically, the control unit 20 has a test simulation control unit 21 and a temperature control unit 22. The test simulation control unit 21 controls the operation of the specimen test simulation unit 10. The temperature control unit 22 controls the operation of the heat generation simulation unit 30 so as to simulate the heat generation of the device simulated by the specimen test simulation unit 10. The configuration of the test simulation control unit 21 is the same as that of a conventional device, and therefore a detailed description thereof will be omitted. The detailed configuration of the temperature control unit 22 will be described later.

[0038] (Refrigerant circuit including heat exchanger) Fig. 2 is a functional block diagram showing a detailed configuration of the simulator 1. Fig. 2 shows an example of a configuration in which heat generated in the specimen test simulation section 10 is recovered by a heat exchange section 31.

[0039] As shown in Fig. 2, the simulator 1 has a refrigerant circuit 40 configured to recover heat generated in the specimen test simulation section 10 in the heat generation simulation section 30. The refrigerant circuit 40 includes a first heat exchanger 41, a second heat exchanger 42, a heat exchanger cooling section 43, a valve 44, a pump P, and the heat exchange section 31 of the heat generation simulation section 30. In the refrigerant circuit 40, the first heat exchanger 41, the second heat exchanger 42, the heat exchanger cooling section 43, the valve 44, the pump P, and the heat exchange section 31 of the heat generation simulation section 30 are connected by refrigerant piping through which a refrigerant flows. Note that in Fig. 2, the refrigerant piping is shown by solid lines.

[0040] In the refrigerant circuit 40, the refrigerant outlet side of the first heat exchanger 41 is connected to the refrigerant inlet side of the heat exchange section 31 of the heat generation simulation section 30 and the refrigerant inlet side of the second heat exchanger 42 so as to be selectively connected by a valve 44. A pump P is provided between the valve 44 and the refrigerant inlet side of the heat exchange section 31 of the heat generation simulation section 30. The refrigerant inlet side of the first heat exchanger 41 is connected to the refrigerant outlet side of the heat exchange section 31 of the heat generation simulation section 30 and the refrigerant outlet side of the second heat exchanger 42.

[0041] The first heat exchanger 41 is configured to be able to recover heat generated in the specimen test simulation section 10. The second heat exchanger 42 is configured to be able to dissipate the heat recovered by the first heat exchanger 41 using a heat exchanger cooling section 43. The first heat exchanger 41 and the second heat exchanger 42 have the same configuration as conventional heat exchangers, so detailed explanations will be omitted. The heat exchanger cooling section 43 is, for example, a fan or a cooling element (e.g., a Peltier element).

[0042] The valve 44 is a three-way valve having a general configuration. The pump P is a pump having a general configuration. Therefore, detailed descriptions of the valve 44 and the pump P will be omitted.

[0043] With the above configuration, by switching the valve 44, it is possible to switch between a flow path in which the refrigerant flows from the first heat exchanger 41 to the second heat exchanger 42 and a flow path in which the refrigerant flows from the first heat exchanger 41 to the heat exchange section 31 of the heat generation simulation section 30. Therefore, it is possible to easily switch between dissipating the heat collected by the first heat exchanger 41 in the second heat exchanger 42 and transferring it to the heat exchange section 31 of the heat generation simulation section 30.

[0044] By flowing the refrigerant from the first heat exchanger 41 to the heat exchange section 31 of the heat generation simulation section 30, the heat generated in the specimen test simulation section 10 and recovered by the first heat exchanger 41 can be transferred to the heat exchange section 31 of the heat generation simulation section 30, thereby simulating heat generation. On the other hand, by flowing the refrigerant from the first heat exchanger 41 to the second heat exchanger 42, the heat generated in the first heat exchanger 41 can be dissipated by the second heat exchanger 42 and the heat exchanger cooling section 43.

[0045] (Temperature control) Next, the control of the heat generation simulation of the heat generation simulator 30 by the temperature controller 22 will be described with reference to Figures 2 and 3. Figure 3 is a functional block diagram showing the general configuration of the temperature controller 22. In Figure 2, the command signal is indicated by a dashed line, and the output of the specimen test simulator 10 is indicated by a thick line.

[0046] 2 and 3, the temperature control unit 22 receives as input values ​​the measurement results from the measurement unit 11 that measures the output of the specimen test simulation unit 10. When the specimen test simulation unit 10 simulates a battery device, the output is a current and a voltage, and the input values ​​are a current value and a voltage value. In addition, the temperature control unit 22 receives as input a temperature measurement value from the temperature measurement unit 34 of the heat generation simulation unit 30.

[0047] 3, temperature control unit 22 calculates a target temperature based on the input values, determines a correction amount so that the measured temperature value becomes the target temperature, and generates the correction amount as a command value. In detail, temperature control unit 22 has a target value calculation unit 23, a target temperature correction unit 24, a valve command generation unit 25, a heat generation assist command generation unit 26, a flow rate command generation unit 27, and a cooling command generation unit 28.

[0048] The target value calculation unit 23 calculates the target temperature based on the input value input from the measurement unit 11. Specifically, the target value calculation unit 23 determines the target temperature according to the output of the specimen test simulation unit 10. This allows the temperature control unit 22 to set the target temperature according to the operating state of the device simulated by the specimen test simulation unit 10. Note that the target value calculation unit 23 may store a table of target temperatures according to the operating state of the device simulated by the specimen test simulation unit 10, or may calculate the target temperature according to the operating state using a formula or the like.

[0049] The target temperature correction unit 24 calculates a correction amount so that the temperature measurement value input from the temperature measurement unit 34 becomes the target temperature calculated by the target value calculation unit 23. This makes it possible to calculate the temperature change required by the heat generation simulation unit 30. Based on this temperature change, the valve command generation unit 25, the heat generation auxiliary command generation unit 26, the flow rate command generation unit 27, and the cooling command generation unit 28 each generate a command value.

[0050] That is, for example, when the temperature change is positive, the valve command generation unit 25 generates a command to switch the valve 44 so that the refrigerant flows from the first heat exchanger 41 to the heat exchange unit 31 of the heat generation simulation unit 30, while when the temperature change is negative, the valve command generation unit 25 generates a command to switch the valve 44 so that the refrigerant flows from the first heat exchanger 41 to the second heat exchanger 42.

[0051] For example, if the temperature change is positive and the heat quantity of the heat exchanger 31 alone is insufficient, the auxiliary heat generation command generator 26 generates a command to drive the auxiliary heat generation unit 32 to make up for the shortage.

[0052] The flow rate command generating unit 27 generates a command to drive the pump P so as to change the flow rate of the refrigerant flowing through the refrigerant circuit 40 in accordance with the temperature change, for example.

[0053] For example, when the temperature change is negative, the cooling command generation unit 28 generates a command to drive the cooling unit 33 to cool the heat exchange unit 31 of the heat generation simulation unit 30. Furthermore, for example, when there is no need to cool the heat generation simulation unit 30, the cooling command generation unit 28 generates a command to drive the heat exchanger cooling unit 43 to cool the second heat exchanger 42.

[0054] In the configuration of this embodiment, the simulation device 1 has a specimen test simulation unit 10 that simulates an input device or an output device and tests a specimen M, a heat generation simulation unit 30 that uses heat generation in the specimen test simulation unit 10 to simulate heat generation in the input device or the output device, and a control unit 20 that controls the operation of the heat generation simulation unit 30 in accordance with the operation of the specimen test simulation unit 10.

[0055] This makes it possible to simulate the heat generation in the input side device or the output side device by utilizing the heat generation in the specimen test simulation unit 10 that simulates the input side device or the output side device and tests the specimen M. Therefore, it is not necessary to supply power to simulate the heat generation in the input side device or the output side device.

[0056] Furthermore, the control unit 20 can control the driving of the heat generation simulation unit 30 that simulates the above-mentioned heat generation in accordance with the operation of the specimen test simulation unit 10. This allows the heat generation simulation unit 30 to be driven in accordance with the operation of the specimen test simulation unit 10.

[0057] Therefore, it is possible to realize a simulator that can simulate not only the characteristics of a simulated device used in a performance test, but also the heat generated in the simulated device.

[0058] In this embodiment, the control unit 20 controls the driving of the specimen test simulation unit 10 in addition to the heat generation simulation unit 30 .

[0059] This allows the control unit 20 to control the driving of both the heat generation simulation unit 30 and the specimen test simulation unit 10. Therefore, the driving of the heat generation simulation unit 30 and the specimen test simulation unit 10 can be controlled in an integrated manner. For example, by making a correction such as reducing the output efficiency of the specimen test simulation unit 10 according to the battery temperature, it is possible to simulate a decrease in battery efficiency when the temperature is low. Therefore, the heat generation simulation unit 30 can be driven more accurately according to the operation of the specimen test simulation unit 10.

[0060] In this embodiment, the heat generation simulation unit 30 has an auxiliary heat generation unit 32 that is driven and controlled by the control unit 20 and generates heat to assist in simulating the heat generation of the input side device or the output side device.

[0061] As a result, the auxiliary heat generating unit 32 can assist in simulating the heat generation of the input side device or the output side device. Therefore, even if the amount of heat generated by the specimen test simulation unit alone is insufficient, the auxiliary heat generating unit can make up for the lacking amount of heat. Furthermore, it can also simulate short-term temperature changes that the heat exchange unit 31 cannot follow. Therefore, the simulator 1 can accurately simulate the heat generation of the input side device or the output side device.

[0062] In this embodiment, the heat generation simulation section 30 has a heat exchange section 31 for recovering the heat generated in the specimen test simulation section 10 .

[0063] As a result, the heat generation simulation section 30 can efficiently recover the heat generated in the specimen test simulation section 10 by the heat exchange section 31. Therefore, by utilizing the recovered heat, the simulation device 1 can simulate the heat generation of the input side device or the output side device with minimal power consumption.

[0064] In this embodiment, the heat generation simulation unit 30 has a cooling unit 33 that cools the heat exchange unit 31 so as to simulate the heat generation of the input side device or the output side device.

[0065] As a result, if the amount of heat generated in the specimen test simulation unit 10 is greater than the amount of heat generated by the input side device or the output side device, the amount of heat generated can be adjusted to match the amount of heat generated by the input side device or the output side device by cooling the heat exchange unit 31 with the cooling unit 33. Therefore, the simulator 1 can more accurately simulate the heat generated by the input side device or the output side device.

[0066] (Other embodiments) Although the embodiments of the present invention have been described above, the above-described embodiments are merely examples for carrying out the present invention. Therefore, the present invention is not limited to the above-described embodiments, and it is possible to appropriately modify the above-described embodiments within the scope of the spirit of the present invention.

[0067] In the above embodiment, the simulator 1 includes a specimen test simulation unit 10, a control unit 20, and a heat generation simulation unit 30. However, the heat generation simulation unit may be provided in a device separate from the device in which the specimen test simulation unit is provided. Also, the control unit that controls the heat generation simulation unit and the control unit that controls the specimen test simulation unit may be configured as separate devices.

[0068] In the above embodiment, the heat generation simulation unit 30 has the auxiliary heat generation unit 32. However, the heat generation simulation unit does not necessarily have to have the auxiliary heat generation unit.

[0069] In the above embodiment, the heat generation simulation unit 30 has a heat exchange unit 31. However, the heat generation simulation unit may have another configuration as long as the heat generated in the specimen test simulation unit can be used for heat generation simulation. The heat generation simulation unit does not need to have a refrigerant circuit as disclosed in the above embodiment as long as the heat generated in the specimen test simulation unit can be used for heat generation simulation.

[0070] In the above embodiment, the heat generation simulation unit 30 has a cooling unit 33 that cools the heat exchange unit 31. However, the heat generation simulation unit does not necessarily have to have a cooling unit.

[0071] In the embodiment, the temperature control unit 22 calculates a correction amount such that the temperature measurement value of the temperature measurement unit 34 becomes the target temperature, using the measurement result of the temperature measurement unit 34 of the heat generation simulator 30. However, the temperature control unit does not have to calculate the correction amount using the measurement result.

[0072] In the above-described embodiment, when the specimen M is an inverter device and a motor is connected to the inverter device, or when the specimen M is a motor, a dynamo that applies a load to the output of the motor may be connected to the motor. In this case, the regenerative power obtained by the dynamo may be recovered by the simulator 1 and used to drive the simulator 1. For example, the regenerative power may be used as power for the auxiliary heat generation unit 32 of the heat generation simulation unit 30 of the simulator 1. [Industrial Applicability]

[0073] The present invention can be used for a simulator that can simulate the characteristics of a simulated device used in a performance test, as well as the heat generated in the simulated device. [Explanation of symbols]
