Description

[Technical field]

[0001] The present disclosure relates to a technique capable of adjusting the temperature of each part of a moving body such as a vehicle. [Background technology]

[0002] Conventionally, there has been a demand for BEVs (i.e., electric vehicles that run only on batteries) to increase their driving range in winter and to shorten the charging time of the batteries. BEV is an abbreviation for Battery Electric Vehicle.

[0003] It is also known that, as a characteristic of a battery, when the temperature of the battery rises to a predetermined desired temperature, the driving range can be extended and the charging time can be shortened. Therefore, in order to increase the driving range and shorten the charging time of the battery, a technique is known for raising the temperature of the battery to a predetermined temperature during the winter season, etc.

[0004] Incidentally, a technique that utilizes heat generated by a motor generator (i.e., MG) inside a vehicle has been disclosed as a method for heating components (i.e., devices) whose performance changes depending on temperature, such as batteries (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0005] [Patent Document 1] US Patent Application Publication No. 2019 / 0070924 Summary of the Invention [Problem to be solved by the invention]

[0006] However, as a result of detailed investigation by the inventors, the following problems were found in the conventional techniques. In the conventional technology, the heat generated in the inverter and the MG can be utilized, but the heat is only transported to the same device.

[0007] In other words, there had been insufficient consideration of technology for utilizing the heat generated by heat-generating devices such as inverters and MGs to raise the temperature of various devices inside the vehicle (i.e., devices that should be kept at a moderate temperature), and further improvements were required.

[0008] One aspect of the present disclosure aims to provide a technology that can improve various performance aspects of a mobile body by effectively utilizing heat generated by equipment capable of generating heat in the mobile body. [Means for solving the problem]

[0009] a) One aspect of the present disclosure relates to a temperature adjustment device for a moving body (3) that adjusts the temperature of equipment inside the moving body. The temperature control device for a moving body includes a circuit (7) for a heat refrigerant and a control unit (61) for controlling the operation of the circuit.

[0010] The components of the circuit include an inverter (43), a motor (45), a pipe (H) that serves as a flow path for the thermal refrigerant, and a valve (V1) that is disposed in the pipe and configured to be able to switch the flow path of the thermal refrigerant.

[0011] In addition to the piping leading to the inverter and the piping leading to the motor, one or more pipes are connected to the valve, and the valve is configured to be switchable so as to transport the heat refrigerant supplied from the upstream side of the valve to at least one of the multiple pipes downstream of the valve.

[0012] The control unit includes a transport control unit (61A) that controls the valve so that, when at least one of the inverter and the motor satisfies a heat generation condition capable of heating the thermal refrigerant, the thermal refrigerant is transported in the thermal refrigerant flow path from at least one of the inverter and the motor that satisfies the condition to a destination located downstream of the one of the inverter and the motor.

[0013] With this configuration, the present disclosure makes it possible to effectively utilize heat generated by devices capable of generating heat in a mobile object, thereby improving various performances of the mobile object. In other words, when the inverter or motor satisfies the heat generation condition, the heat refrigerant (i.e., heat medium) supplied to the inverter or motor can be heated. Therefore, by switching the destination of the heated heat refrigerant with a valve, the heat of the heat refrigerant can be effectively utilized to efficiently heat the device to be heated.

[0014] b) Another aspect of the present disclosure relates to a computer program for controlling a temperature adjustment device (3) for a moving object that adjusts the temperature of equipment inside a moving object (1). The temperature control device for a mobile body includes, as components of a thermal refrigerant circuit, an inverter (43), a motor (45), a pipe (H) that serves as a flow path for the thermal refrigerant, and a valve (V1) that is disposed in the pipe and configured to be able to switch the flow path of the thermal refrigerant.

[0015] In addition to the piping leading to the inverter and the piping leading to the motor, one or more pipes are connected to the valve, and the valve is configured to be switchable so as to transport the heat refrigerant supplied from the upstream side of the valve to at least one of the multiple pipes downstream of the valve.

[0016] The computer is equipped with a program for functioning as a transport control unit (61A) that controls the valve so that, when at least one of the inverter and the motor satisfies a heat generation condition capable of heating the thermal refrigerant, the thermal refrigerant is transported in the thermal refrigerant flow path from at least one of the inverter and the motor that satisfies the condition to a destination located downstream of the one of the inverter and the motor.

[0017] With this configuration, the present disclosure makes it possible to effectively utilize heat generated by devices capable of generating heat in a mobile object, thereby improving various performances of the mobile object. In other words, when the inverter or motor satisfies the heat generation condition, the heat refrigerant (i.e., heat medium) supplied to the inverter or motor can be heated. Therefore, by switching the destination of the heated heat refrigerant with a valve, the heat of the heat refrigerant can be effectively utilized to efficiently heat the device to be heated.

[0018] Furthermore, the symbols in parentheses in this column and in the claims indicate a correspondence with the specific means described in the embodiment described later as one aspect, and do not limit the technical scope of the present disclosure. [Brief description of the drawings]

[0020] Hereinafter, exemplary embodiments of the present disclosure will be described with reference to the drawings. [1. First embodiment] In the first embodiment, a temperature control device for a moving body that can adjust the temperature of various devices mounted on an electrically-driven moving body will be described. Note that, in the following, a vehicle that runs only on electricity (i.e., a BEV) will be described as an example of an electrically-driven moving body.

[0021] [1-1. Overall composition] 1, in the first embodiment, a vehicle 1 is equipped with a vehicle system 3. The vehicle system 3 is a system having the function of a temperature adjustment device for a moving body, and includes a refrigerant circuit 5 having a heat pump (i.e., HP) function, a temperature adjustment circuit 7 capable of adjusting the temperature of various devices mounted on the vehicle 1, a vehicle control device 9 that controls the operation of the refrigerant circuit 5 and the temperature adjustment circuit 7 and the operation of other devices of the vehicle 1, a well-known navigation device 11, etc.

[0022] The refrigerant circuit 5 and the temperature adjustment circuit 7 constitute a circuit system 13. The circuit system 13 is provided with a flow path through which a thermal refrigerant, which is a heat medium, flows. The temperature adjustment circuit 7 may be regarded as a circuit having the function of a temperature adjustment device for a mobile body.

[0023] Each component will be described below. [1-2.Each configuration] <Refrigerant circuit> 2, the refrigerant circuit 5 is a known circuit through which a thermal refrigerant flows, and includes an accumulator 21, a compressor 23, a water-cooled condenser (i.e., a water-cooled con) 25, a chiller 27, etc. In the refrigerant circuit 5, the thermal refrigerant flows in a gas or liquid state, as is known.

[0024] The accumulator 21 is a device that separates gas and liquid and accumulates gas (i.e., gaseous heat refrigerant, etc.), and the compressor 23 is a device that compresses the heat refrigerant. The water-cooled condenser 25 is a device that is arranged at both the boundary portions between the refrigerant circuit 5 and the temperature control circuit 7 and heats the heat refrigerant of the temperature control circuit 7 (i.e., a heat refrigerant having a lower temperature than the heat refrigerant of the refrigerant circuit 5) by the heat refrigerant of the refrigerant circuit 5. The chiller 27 is a device that is arranged at both the boundary portions between the refrigerant circuit 5 and the temperature control circuit 7 and cools the heat refrigerant of the temperature control circuit 7 (i.e., a heat refrigerant having a higher temperature than the heat refrigerant of the refrigerant circuit 5) by the heat refrigerant of the refrigerant circuit 5. In other words, in the present disclosure, a heat exchanger for cooling the heat refrigerant in the temperature control circuit 7 (i.e., a part that exchanges heat between the refrigerant circuit 5 and the temperature control circuit 7) is referred to as a chiller.

[0025] In Fig. 2, the pipe H through which the thermal refrigerant flows (i.e., the flow path of the thermal refrigerant) is shown by a solid line, and the arrows of the solid line indicate the direction in which the thermal refrigerant flows. In the following other drawings, the arrows of each flow path also indicate the direction in which the thermal refrigerant flows.

[0026] Further, a compressor 23 is disposed downstream of the accumulator 21, and the flow path downstream of the compressor 23 branches and is connected to the accumulator 21 and the water-cooled condenser 25. A chiller 27 is disposed downstream of the water-cooled condenser 25, and the accumulator 21 is disposed downstream of the chiller 27.

[0027] In addition, a well-known electronically controlled valve (i.e., EXV) 31, which is an opening / closing valve, is arranged in the piping H1 extending from the branch point downstream of the compressor 23 to the accumulator 21, and a similar electronically controlled valve 33 is also arranged in the piping H2 extending from the water-cooled condenser 25 to the chiller 27.

[0028] <Temperature control circuit> 2, the temperature adjustment circuit 7 is a circuit through which a thermal refrigerant flows, and the thermal refrigerant (for example, water) flows in a liquid state. The components of the temperature adjustment circuit 7 include a cell (i.e., a battery) 41, an inverter 43, a motor generator 45, a heater core 47, a radiator 49, the water-cooled condenser 25, the chiller 27, a plurality of flow path switching valves V, a plurality of pumps P, etc. Note that here, an ECU 53 that adjusts the DC-DC voltage is provided, but this may be omitted. Furthermore, the components are connected by piping H through which the thermal refrigerant flows.

[0029] The battery 41 is a rechargeable battery (i.e., a secondary battery) used for driving the vehicle 1, and can be charged by a charger (not shown) or the like outside the vehicle 1. Also, electricity generated by the motor generator 45 can be stored in the battery 41.

[0030] The inverter 43 is a well-known device that converts direct current into alternating current. The motor generator (MG) 45 is a well-known device that functions as both a motor and a generator. Note that, hereinafter, the motor generator 45 may be simply referred to as a motor, or in the drawings as an MG.

[0031] The heater core 47 is a well-known device that is heated by heat from the heat refrigerant flowing through the temperature adjustment circuit 7 or heat transferred from the refrigerant circuit 5 and is used to heat the interior of the vehicle 1. The radiator 49 is a well-known device used for exchanging heat with the outside air.

[0032] The pumps (for example, water pumps) P (for example, P1 to P4) are well-known devices that cause the heat refrigerant in the pipes H to flow in a fixed direction. The pumps P are driven as necessary, but may not be driven in some cases.

[0033] The flow path switching valve V is an eight-way switching valve that can switch the flow path to eight directions by a control signal from the vehicle control device 9. In FIG. 2 and other figures, the flow path switching valve V includes a first valve V1, a second valve V2, and a third valve V3.

[0034] The flow path switching valve V has eight openings and internal flow paths connected to the openings. Each opening can be connected to a pipe H. The pipe H does not have to be connected to all of the eight openings.

[0035] In Figure 7 etc. described later, the internal flow paths are typically indicated by arrows on the surface and inside of the flow path switching valve V, and the corners of the surface of the flow path switching valve V (for example, the connection parts of the arrows) typically indicate openings.

[0036] Therefore, as described in detail later, when the flow path switching valve V is rotatable around a central axis (e.g., a central axis perpendicular to the plane of the paper in FIG. 2), each time the flow path switching valve V is rotated a predetermined angle, the connection state between each opening and each pipe H is changed, and the flow path of the thermal refrigerant is switched.

[0037] <Vehicle control device> As shown in FIG. 3A, the vehicle control device 9 includes a calculation processing unit 61 for performing calculations for various controls and the like.

[0038] The arithmetic processing unit 61 is mainly composed of a microcomputer (hereinafter, "microcomputer") having a CPU 63 and a semiconductor memory such as a ROM, a RAM, a flash memory, etc. (hereinafter, "memory 65"). Various functions of the arithmetic processing unit 61 are realized by the CPU 63 executing a program stored in a non-transitive substantial recording medium. In this example, the memory 65 corresponds to the non-transitive substantial recording medium storing the program. Furthermore, by executing this program, a method corresponding to the program is performed.

[0039] The number of microcomputers constituting the arithmetic processing unit 61 may be one or more. Furthermore, the method of realizing the various functions of the arithmetic processing unit 61 is not limited to software, and some or all of the elements may be realized using one or more pieces of hardware. For example, when the above functions are realized by electronic circuits that are hardware, the electronic circuits may be realized by digital circuits including a large number of logic circuits, or analog circuits, or a combination of these.

[0040] Various detection devices (e.g., sensors) are connected to the vehicle control device 9 to detect the status of the vehicle 1, etc., and detection signals indicating each status obtained from each detection device are output to the vehicle control device 9.

[0041] The detection devices include an opening sensor S1 that detects the opening of the first valve V1, an opening sensor S3 that detects the opening of the second valve V2, and an opening sensor S3 that detects the opening of the third valve V3.

[0042] It should be noted that the opening degree here is a value corresponding to the angle (i.e., the valve angle) indicating how many degrees it has been rotated from a reference position, and as will be described later, once this valve angle is determined, it is determined which pipe H each opening of each valve V is connected to.

[0043] Further detection equipment includes flow rate sensors 71 for detecting the flow rate of the thermal refrigerant flowing through each pump P, a temperature sensor 73 for detecting the temperature of the battery 41, a temperature sensor 75 for detecting the temperature of the inverter 43, a temperature sensor 77 for detecting the temperature of the motor 45, a temperature sensor 79 for detecting the temperature of the radiator 49, a temperature sensor 81 for detecting the temperature of the heater core 47, a temperature sensor 83 for detecting the temperature of the chiller 27, a temperature sensor 85 for detecting the temperature of the surrounding environment (e.g., outside air temperature), and a temperature sensor 87 for detecting the temperature inside the vehicle.

[0044] Further, various actuators are connected to the vehicle control device 9 in order to perform various operations of the vehicle 1 etc., and the vehicle control device 9 outputs control signals to the actuators for operating the actuators.

[0045] The actuators include the valves V: a first valve V1, a second valve V2, and a third valve V3. Further, the actuators include each pump P, a battery 41, an inverter 43, a motor 45, EXVs 31 and 33, a compressor 23, and the like.

[0046] The arithmetic processing unit 61, as shown in FIG. 3B, functionally includes a transport control unit 61A and a heat generation control unit 61B. The transport control unit 61A is configured to control the first valve V1 so that when at least one of the inverter 43 and the motor 45 satisfies the heat generation condition capable of heating the heat refrigerant (i.e., the heat refrigerant in the temperature control circuit 7) (e.g., when temperature increase control is performed), the heat refrigerant is transported in the heat refrigerant flow path from at least one of the inverter 43 and the motor 45 that satisfies the condition to a destination located downstream of it (i.e., downstream of at least one of the inverter 43 and the motor 45 that satisfies the condition).

[0047] The heat generation control unit 61B is configured to perform temperature increase control, in which a current is passed through at least one of the inverter 43 and the motor 45 to generate heat, as the control that satisfies the above-mentioned condition, for example.

[0048] Therefore, when the calculation processing unit 61 performs temperature rise control on at least one of the inverter 43 and the motor 45, the calculation processing unit 61 can control the first valve V1 so as to transport the thermal refrigerant to a destination located downstream of at least one of the inverter 43 and the motor 45 on which the temperature rise control was performed.

[0049] In addition, conditions for heat generation (i.e., conditions under which the thermal refrigerant can be heated by the inverter 43 or the motor 45) include a condition in which at least one of the inverter 43 and the motor 45 reaches a predetermined temperature or higher, in addition to the condition in which at least one of the inverter 43 and the motor 45 is temperature-raising controlled.

[0050] [1-3.Characteristic configuration] Here, a characteristic configuration in the first embodiment will be described. A pipe H for a heat refrigerant is provided near the inverter 43, the motor 45, and the battery 41. Therefore, the heat generated by the inverter 43, the motor 45, and the battery 41 is transferred to a target configuration (e.g., a component such as the battery 41) such as a target for temperature increase (i.e., a target for increasing the temperature) by the heat refrigerant flowing through the pipe H. Conversely, the heat refrigerant flowing through the pipe H can heat each component such as the inverter 43, the motor 45, and the battery 41.

[0051] In the following description, without mentioning this pipe H, it may be simply stated as "the heat refrigerant that has passed through the inverter 43 and the motor 45" or "the heat refrigerant that is transported to the inverter 43 and the motor 45", etc.

[0052] <Temperature control circuit configuration> As shown in FIG. 4A, in the first embodiment, in the configuration of the temperature adjustment circuit 7, a first valve V1 is provided between a pipe H connecting the heat refrigerant outlet side of the inverter 43 and the heat refrigerant inlet side of the motor 45.

[0053] The first valve V1 is configured to switch the flow path of the thermal refrigerant, for example, so that the thermal refrigerant that has passed through the temperature-controlled inverter 43 is transported directly through piping H or indirectly via another valve V to at least one of the destinations: the battery 41, the chiller 27, the heater core 47, the radiator 49, and the motor 45.

[0054] In addition to FIG. 4A, in the configuration of the temperature adjustment circuit 7, as shown in FIG. 4B, a first valve V1 may be provided between the pipe H connecting the heat refrigerant outlet side of the motor 45 and the heat refrigerant inlet side of the inverter 43.

[0055] In this case, the first valve V1 is configured to be able to switch the flow path of the heat refrigerant so that the heat refrigerant that has passed through the temperature-controlled motor 45 is transported to at least one of the destinations of the battery 41, the chiller 27, the heater core 47, and the radiator 49 directly through the piping H or indirectly through another valve V. As will be described later, the heat refrigerant may be transported to the motor 45 itself or the like through a closed circuit.

[0056] <Heat generation action> Next, the heat generating operation in the inverter 43 and the motor 45 will be described. Here, heat generation refers to an operation for generating heat, separate from the normal operation of the inverter 43 and the motor 45, that is, an operation for passing a current through the inverter 43 itself and the motor 45 itself for the purpose of generating heat. In the first embodiment, the vehicle control device 9 performs temperature increase control for generating heat by passing a current for the purpose of generating heat.

[0057] Specifically, the inverter 43 can generate heat by temperature control such as switching control that causes a current to flow through a diode with a large loss, while the motor 45 can generate heat by temperature control that causes a current to flow through one of the three phases to operate inefficiently.

[0058] 5, in the case of heat generation, the power consumption per unit time of the inverter 43 is, for example, 4.2 kW, and the power consumption per unit time of the motor 45 is, for example, 6 kW. In other words, the power consumption per unit time of the motor 45 is greater than that of the inverter 43. Therefore, the amount of heat generated per unit time of the motor 45 is greater than that of the inverter 43.

[0059] In addition, when the same amount of power is supplied, the temperature of the inverter 43 rises more quickly than that of the motor 45. That is, the inverter 43 has a higher responsiveness than the motor 45. Furthermore, the motor 45 has a larger heat capacity than the inverter 43, and therefore has a higher heat storage capacity.

[0060] Therefore, the inverter 43 and the motor 45 are used appropriately according to the above-mentioned characteristics, as will be described later. Specifically, heat generation by the inverter 43 is performed, for example, during the period from the start to the completion of warming up of devices such as the battery 41, a predetermined period from the start of charging the battery 41, a predetermined period for defrosting while warming up various devices (e.g., during heating), and a predetermined period from the start of warming up the motor 45.

[0061] In addition, heat generation by the motor 45 is performed, for example, during the latter half to completion of warming up of devices such as the battery 41, the entire period when the battery 41 is being charged, and a specified period of defrosting after warming up various devices.

[0062] It should be noted that the warming up here means heating devices such as the battery 41 and the motor 45 to a predetermined temperature suitable for operation. <Heat transfer path after heat generation> As shown in the upper part of FIG. 6 (i.e., the top three columns), heat generated by heat generation by the inverter 43 and / or the motor 45 (i.e., by temperature increase control) is transferred to a target object to be heated via each path. For example, the heat refrigerant heated by the inverter 43 or the motor 45 is transported to a target destination via each path. The area indicated by the dashed line in FIG. 6 is a characteristic configuration of the first embodiment.

[0063] For example, the hot refrigerant heated by the inverter 43 is transported to the heater core 47 for the purpose of heating the interior of the vehicle. The heat of the hot refrigerant is transferred to the heater core 47 via the chiller 27 and the water-cooled condenser 25 for the purpose of heating the interior of the vehicle. The hot refrigerant is transported to the battery 41 for the purpose of warming up the battery 41. The hot refrigerant is transported to the radiator 49 for the purpose of defrosting the radiator 49. The hot refrigerant is transported to the motor 45 for the purpose of warming up the motor 45.

[0064] On the other hand, the hot refrigerant heated by the motor 45 is transported to the heater core 47 for the purpose of heating the interior of the vehicle. The heat of the hot refrigerant is transferred to the heater core 47 via the chiller 27 and the water-cooled condenser 25 for the purpose of heating the interior of the vehicle. The hot refrigerant is transported to the battery 41 for the purpose of warming up the battery 41. The hot refrigerant is transported to the radiator 49 for the purpose of defrosting the radiator 49. The hot refrigerant is transported to the motor 45 itself for the purpose of warming up the motor 45 itself.

[0065] Furthermore, the hot refrigerant heated by the inverter 43 and the motor 45 is transported to the heater core 47 for the purpose of heating the interior of the vehicle. Also, the heat of the hot refrigerant is transferred to the heater core 47 via the chiller 27 and the water-cooled condenser 25 for the purpose of heating the interior of the vehicle. Also, the hot refrigerant is transported to the battery 41 for the purpose of warming up the battery 41. Also, the hot refrigerant is transported to the radiator 49 for the purpose of defrosting the radiator 49.

[0066] The object to be heated can also be heated by controlling the lower part of FIG. 6 (that is, the lower three columns), so a brief explanation will be given here. For example, the heat of the outside air is transferred to the heater core 47, the battery 41, and the motor 45 via the radiator 49, the chiller 27, the water-cooled condenser 25, etc., for the purposes of heating the interior of the vehicle, warming up the battery 41, and warming up the motor 45, respectively.

[0067] The heat from the outside air and the heat generated by the inverter 43 is transferred to the heater core 47 and the battery 41 via the chiller 27, the water-cooled condenser 25, etc., for the purpose of heating the interior of the vehicle and warming up the battery 41, respectively.

[0068] Heat generated by the battery 41 (for example, heat generated by a ripple current) is transferred to the heater core 47 via the chiller 27 and the water-cooled condenser 25 for the purpose of heating the interior of the vehicle. In addition, the heat refrigerant heated by the heat generated by the battery 41 is supplied to the motor 45 for the purpose of warming up the motor 45.

[0069] [1-4. Operation] Next, a specific operation example in the first embodiment (that is, the operation example of the contents of FIG. 6) will be described in detail.

[0070] <Example 1> As shown in the dashed-line frame in FIG. 7B, a case will be described in which the heat refrigerant is heated by the heat generated by inverter 43 and transported to heater core 47 for the purpose of heating the interior of the vehicle.

[0071] 7A, each valve V has an opening (i.e., an angle determined by rotation) set so that the thermal refrigerant flows in the direction shown by the arrow in the figure. Note that outside each valve V, the thermal refrigerant flows in piping H shown by solid lines, dashed lines, etc., and inside each valve V, the thermal refrigerant flows through internal flow paths shown by solid lines, dashed lines, etc.

[0072] In addition, in Fig. 7A, the lines such as solid lines indicating the internal flow paths intersect, but in reality, the internal flow paths indicated by the lines are provided so as not to merge midway. The same applies to the following figures. First, the hot refrigerant heated by the inverter 43 is transported to the water-cooled condenser 25 via the first valve V1 as shown by the dashed line, receives heat from the refrigerant circuit 5 in the water-cooled condenser 25, and is transported to the heater core 47 to heat the heater core 47. Then, the air inside the vehicle is heated by the heater core 47.

[0073] Thereafter, the hot refrigerant passes from the heater core 47 through the first valve V1, the pump P1, the third valve V3, the second valve V2, the pump P2, and the ECU 53 and returns to the inverter 43. The components such as the valve V are connected by pipes H, and the heat refrigerant in the pipes H moves so as to be pumped out by a pump P.

[0074] In this operation example 1, heat is not generated by the motor 45. As shown by the solid line, the heat refrigerant flows from the motor 45 through the second valve V2, the pump P3, the first valve V1, the battery 41, the second valve V2, the third valve V3, and the first valve V1, and returns to the motor 45.

[0075] The refrigerant that has been heat exchanged (ie, cooled) in the chiller 27 returns to the chiller 27 via the pump P4, the third valve V3, the radiator 49, and the third valve V3, as indicated by the dashed line.

[0076] Each of the pumps P1 to P4 is operating to circulate the heat refrigerant. In the following description, each of the pumps P1 to P4 is assumed to be operating unless it is indicated that the pumps are stopped. <Example 2> As shown within the dashed frame in FIG. 8B, a case will be described in which the heat refrigerant is heated by heat generation from the inverter 43, and the heat of the refrigerant is transferred to the heater core 47 via the chiller 27 and the water-cooled condenser 25 for the purpose of heating the interior of the vehicle.

[0077] As shown in FIG. 8A, the refrigerant heated by the inverter 43 returns to the inverter 43 via the first valve V1, pump P1, third valve V3, chiller 27, pump P4, third valve V3, second valve V2, pump P2, and ECU 53, as indicated by the dashed line.

[0078] In this operation example 2, heat is not generated by the motor 45. As shown by the solid line, the heat refrigerant returns from the motor 45 to the motor 45 via the second valve V2, the pump P3, the first valve V1, the battery 41, the second valve V2, the third valve V3, the first valve V1, the water-cooled condenser 25, the heater core 47, and the first valve V1.

[0079] With the above-mentioned configuration, the temperature of the chiller 27 rises due to the heat refrigerant heated by the inverter 43, and the temperature of the heat refrigerant flowing through the refrigerant circuit 5 side of the chiller 27 rises. Therefore, the temperature of the heat refrigerant flowing through the refrigerant circuit 5 side of the water-cooled condenser 25 also rises, and the temperature of the heater core 47 downstream of the water-cooled condenser 25 also rises. Therefore, the heater core 47 can heat the air inside the vehicle.

[0080] As indicated by a thin dashed line, the flow path connecting the radiator 49 and the third valve V3 is a closed circuit. Here, the closed circuit is a circuit in which components such as the radiator 49 arranged in the closed circuit are not connected to other components (e.g., objects to be heated) (i.e., a closed flow path in which heat is not transferred by a thermal refrigerant). A pump P may be arranged in the closed circuit, and the pump P of the closed circuit may be stopped.

[0081] <Example 3> As shown in the dashed-line frame in FIG. 9B, a case will be described in which the thermal refrigerant is heated by heat generated by inverter 43 and transported to battery 41 for the purpose of warming up battery 41.

[0082] 9A, the refrigerant heated by the inverter 43 returns to the inverter 43 via the first valve V1, the battery 41, the second valve V2, the pump P2, and the ECU 53, as indicated by the dashed line. The battery 41 is heated by the refrigerant heated by the inverter 43.

[0083] In this operation example 3, heat is not generated by the motor 45, but the heat refrigerant returns from the motor 45 to the motor 45 via the second valve V2, the pump P3, and the first valve V1, as indicated by the two-dot chain line.

[0084] The refrigerant heated in the water-cooled condenser 25 returns to the water-cooled condenser 25 via the heater core 47, the first valve V1, the pump P1, the third valve V3, and the first valve V1, as indicated by the solid line.

[0085] Furthermore, the heat refrigerant cooled in the chiller 27 returns to the chiller 27 via the pump P4, the third valve V3, the radiator 49, and the third valve V3, as indicated by the dashed line. As indicated by the thin dashed line, the flow path connecting the second valve V2 and the third valve V3 is a closed circuit.

[0086] <Example 4> As shown in the dashed-line frame in FIG. 10B, a case will be described in which the heat refrigerant is heated by heat generated by inverter 43 and transported to radiator 49 for the purpose of defrosting radiator 49.

[0087] 10A, the refrigerant heated by the inverter 43 returns to the inverter 43 via the first valve V1, the pump P1, the third valve V3, the radiator 49, the third valve V3, the second valve V2, the pump P2, and the ECU 53, as indicated by the dashed line. The radiator 49 is heated by the refrigerant heated by the inverter 43, thereby performing defrosting.

[0088] In this operation example 4, heat is not generated by the motor 45. As shown by the solid line, the heat refrigerant returns from the motor 45 through the second valve V2, the pump P3, the first valve V1, the battery 41, the second valve V2, the third valve V3, the first valve V1, the water-cooled condenser 25, the heater core 47, and the first valve V1 to the motor 45.

[0089] As indicated by the thin dashed line, the flow path connecting the chiller 27 and the third valve V3 is a closed circuit, and the pump P4 is stopped. <Example 5> As shown in the dashed-line frame in FIG. 11B, a case will be described in which the thermal refrigerant is heated by heat generated by inverter 43 and transported to motor 45 for the purpose of warming up motor 45.

[0090] 11A, the heat refrigerant heated by the inverter 43 is transported to the motor 45 via the first valve V1 as indicated by the dashed line, and heats the motor 45. Thereafter, the heat refrigerant returns from the motor 45 to the inverter 43 via the second valve V2, the pump P2, and the ECU 53.

[0091] In addition to the above flow path, the heat refrigerant returns to the battery 41 from the battery 41 via the second valve V2, the pump P3, and the first valve V1, as indicated by the solid line. In addition to the above flow path, the heat refrigerant returns to the water-cooled condenser 25 from the water-cooled condenser 25 via the heater core 47, the first valve V1, the pump P1, the third valve V3, and the first valve V1, as shown by the two-dot chain line.

[0092] In addition to the above flow path, the heat refrigerant returns from the chiller 27 through the pump P4, the third valve V3, the radiator 49, and the third valve V3 to the chiller 27, as indicated by the dashed dotted line. As indicated by the thin dashed line, the flow path connecting the second valve V2 and the third valve V3 is a closed circuit.

[0093] <Example 6> As shown in the dashed-line frame in FIG. 12B, a case will be described in which the heat refrigerant is heated by the heat generated by motor 45 and transported to heater core 47 for the purpose of heating the interior of the vehicle.

[0094] 12A, the refrigerant heated by the motor 45 returns to the motor 45 via the second valve V2, the third valve V3, the first valve V1, the water-cooled condenser 25, the heater core 47, and the first valve V1, as indicated by the dashed line. The refrigerant heated by the motor 45 and the water-cooled condenser 25 heats the air inside the vehicle in the heater core 47.

[0095] In this operation example 6, heat is not generated in the inverter 43, but the heat refrigerant returns from the inverter 43 through the first valve V1, the battery 41, the second valve V2, the pump P2, and the ECU 53 to the inverter 43, as shown by the solid line.

[0096] In addition to the above flow path, the heat refrigerant returns from the chiller 29 to the chiller 27 via the pump P4, the third valve V3, the radiator 49, and the third valve V3, as indicated by the dashed dotted line. It should be noted that pumps P1 and P3 arranged in pipe H indicated by a thin dashed line are stopped.

[0097] <Example 7> As shown within the dashed frame in FIG. 13B, a thermal refrigerant is heated by heat generated by a motor 45, and the heat of the thermal refrigerant is transferred to a heater core 47 via a chiller 27 and a water-cooled condenser 25 for the purpose of heating the interior of the vehicle.

[0098] As shown in FIG. 13A, the refrigerant heated by the motor 45 returns to the motor 45 via the second valve V2, the third valve V3, the chiller 27, the pump P4, the third valve V3, and the first valve V1, as indicated by the dashed line.

[0099] In addition, separate from the above flow path, the heat refrigerant returns to the water-cooled condenser 25 via the water-cooled condenser 25, the heater core 47, the first valve V1, the pump P1, the third valve V3, the second valve V2, the pump P3, and the first valve V1, as shown by the dotted line.

[0100] With the above-mentioned configuration, the temperature of the chiller 27 rises due to the heat refrigerant heated by the motor 45, and the temperature of the heat refrigerant flowing through the refrigerant circuit 5 side of the chiller 27 rises. This also raises the temperature of the heat refrigerant flowing through the refrigerant circuit 5 side of the water-cooled condenser 25, and the air inside the vehicle can be heated by the heater core 47 to which the heat refrigerant with the raised temperature is supplied.

[0101] In this operation example 7, heat is not generated in the inverter 43, but the heat refrigerant returns from the inverter 43 to the inverter 43 via the first valve V1, the battery 41, the second valve V2, the pump P2, and the ECU 53, as shown by the solid line.

[0102] As indicated by the thin dashed line, the flow path connecting the radiator 49 and the third valve V3 is a closed circuit. <Example 8> As shown in the dashed-line frame in FIG. 14B, a case will be described in which the thermal refrigerant is heated by heat generated by motor 45 and transported to battery 41 for the purpose of warming up battery 41.

The battery 41 is heated by the refrigerant heated by the motor 45.

[0104] In this operation example 8, heat is not generated in the inverter 43, but the heat refrigerant returns to the inverter 43 from the inverter 43 via the first valve V1, the water-cooled condenser 25, the heater core 47, the first valve V1, the pump P1, the third valve V3, the second valve V2, the pump P2, and the ECU 53, as shown by the solid line.

[0105] Separately from the above flow path, the heat refrigerant cooled in the chiller 27 returns to the chiller 27 via the pump P4, the third valve V3, the radiator 49, and the third valve V3, as indicated by the dashed dotted line.

[0106] <Example 9> As shown in the dashed-line frame in FIG. 15B, a case will be described in which the heat refrigerant is heated by heat generated by motor 45 and transported to radiator 49 for the purpose of defrosting radiator 49.

[0107] 15A, the refrigerant heated by the motor 45 returns to the motor 45 via the second valve V2, the third valve V3, the radiator 49, the third valve V3, the second valve V2, the pump P3, and the first valve V1, as indicated by the dashed line. The radiator 49 is heated by the refrigerant heated by the motor 45, thereby performing defrosting.

[0108] In this operation example 9, heat is not generated in the inverter 43, but the heat refrigerant returns to the inverter 43 from the inverter 43 via the first valve V1, the water-cooled condenser 25, the heater core 47, the first valve V1, the battery 41, the second valve V2, the pump P2, and the ECU 53, as shown by the solid line.

[0112] In addition to the above flow path, the heat refrigerant returns from the water-cooled condenser 25 via the heater core 47, the first valve V1, the pump P1, the second valve V2, and the first valve V1, as shown by the two-dot chain line.

[0118] 18A, the refrigerant heated by the inverter 43 returns to the inverter 43 via the first valve V1, the water-cooled condenser 25, the heater core 47, the first valve V1, the pump P1, the third valve V3, the second valve V2, the pump P2, and the ECU 53, as indicated by the dashed line. This heats up the heater core 47, and the temperature of the air inside the vehicle increases.

[0120] It should be noted that the pump P4 disposed in the pipe H indicated by the thin dashed line is not driven. <Example 13> As shown in the two dashed boxes in Figure 19B, a case will be described in which the heat refrigerant is heated by heat generation by inverter 43 and transported to heater core 47 for the purpose of heating the vehicle cabin, and the heat refrigerant is heated by heat generation by motor 45 and transported to motor 45 itself for the purpose of storing heat in motor 45.

[0121] 19A, the refrigerant heated by the inverter 43 returns to the inverter 43 via the first valve V1, the water-cooled condenser 25, the heater core 47, the first valve V1, the pump P1, the third valve V3, the second valve V2, the pump P2, and the ECU 53, as indicated by the dashed line. This heats up the heater core 47, and the temperature of the air inside the vehicle increases.

[0122] In addition to the above flow paths, the heat refrigerant heated by the motor 45 returns to the motor 45 via the second valve V2, the pump P3, and the first valve V1, as shown by the solid line.

[0123] In addition to the above flow path, the heat refrigerant returns from the chiller 27 to the chiller 27 via the pump P4, the third valve V3, the radiator 49, and the third valve V3, as indicated by the dashed line. <Example 14> As shown in the two dashed boxes in Figure 20B, a case will be described in which the heat refrigerant is heated by heat generation from the inverter 43, and the heat of the refrigerant is transferred to the heater core 47 via the chiller 27 and the water-cooled condenser 25 for the purpose of heating the interior of the vehicle, and the heat refrigerant is heated by heat generation from the motor 45, and the refrigerant is transported to the battery 41 for the purpose of warming up the battery 41.

[0125] Separately from the above circuit, the refrigerant heated by the motor 45 returns to the motor 45 via the second valve V2, the pump P3, the first valve V1, the battery 41, the second valve V2, the third valve V3, the first valve V1, the water-cooled condenser 25, the heater core 47, and the first valve V1, as shown by the solid line. This allows the battery 41 to be warmed up.

[0126] With the above-mentioned configuration, the temperature of the chiller 27 rises due to the heat refrigerant heated by the inverter 43, and the temperature of the heat refrigerant flowing through the refrigerant circuit 5 side of the chiller 27 rises. As a result, the temperature of the heat refrigerant flowing through the refrigerant circuit 5 side of the water-cooled condenser 25 also rises, and the temperature of the heater core 47 also rises. Therefore, the air inside the vehicle can be heated by this heater core 47.

[0127] As indicated by the thin dashed line, the flow path connecting the radiator 49 and the third valve V3 is a closed circuit. <Example 15> As shown in the two dashed frames in FIG. 21B, a case will be described in which the heat refrigerant is heated by heat generated by the inverter 43, and the heat of the refrigerant is transferred to the heater core 47 via the chiller 27 and the water-cooled condenser 25 for the purpose of heating the interior of the vehicle, and the heat refrigerant is heated by heat generated by the motor 45, and the refrigerant is transported to the radiator 49 for the purpose of defrosting the radiator 49.

[0128] As shown in FIG. 21A, the refrigerant heated by the inverter 43 returns to the inverter 43 via the first valve V1, pump P1, third valve V3, chiller 27, pump P4, third valve V3, second valve V2, pump P2, and ECU 53, as indicated by the dashed line.

This causes the radiator 49 to be defrosted.

[0130] With the above-mentioned configuration, the temperature of the chiller 27 rises due to the heat refrigerant heated by the inverter 43, and the temperature of the heat refrigerant flowing through the refrigerant circuit 5 side of the chiller 27 rises. As a result, the temperature of the heat refrigerant flowing through the refrigerant circuit 5 side of the water-cooled condenser 25 also rises, and the temperature of the heater core 47 also rises. Therefore, the air inside the vehicle can be heated by this heater core 47.

[0131] <Example 16> As shown in the two dashed frames in Figure 22B, a case will be described in which the heat refrigerant is heated by heat generation by inverter 43, and the heat of the heat refrigerant is transferred to heater core 47 via chiller 27 and water-cooled condenser 25 for the purpose of heating the interior of the vehicle, and the heat refrigerant is heated by heat generation by motor 45, and the heat refrigerant is transported to motor 45 for the purpose of storing heat in motor 45.

[0132] As shown in FIG. 22A, the refrigerant heated by the inverter 43 returns to the inverter 43 via the first valve V1, pump P1, third valve V3, chiller 27, pump P4, third valve V3, second valve V2, pump P2, and ECU 53, as indicated by the dashed line.

[0133] In addition to the above circuit, the heat refrigerant heated by the motor 45 returns to the motor 45 via the second valve V2, the pump P3, and the first valve V1, as shown by the solid line.

[0134] With the above-mentioned configuration, the temperature of the chiller 27 rises due to the heat refrigerant heated by the inverter 43, and the temperature of the heat refrigerant flowing through the refrigerant circuit 5 side of the chiller 27 rises. As a result, the temperature of the heat refrigerant flowing through the refrigerant circuit 5 side of the water-cooled condenser 25 also rises, and the temperature of the heater core 47 also rises. Therefore, the air inside the vehicle can be heated by this heater core 47.

[0135] In addition to the above flow path, the heat refrigerant returns to the battery 41 from the battery 41 via the second valve V2, the third valve V3, and the first valve V1, as indicated by the two-dot chain line. As indicated by the thin dashed line, the flow path from the first valve V1 through the water-cooled condenser 25 and the heater core 47 to the first valve V1 is a closed circuit. Also, the flow path connecting the third valve V3 and the radiator 49 is a closed circuit.

[0136] <Example 17> As shown in the two dashed boxes in Figure 23B, a case will be described in which the heat refrigerant is heated by heat generated by the inverter 43 and transported to the battery 41 for the purpose of warming up the battery 41, and the heat refrigerant is heated by heat generated by the motor 45 and the heat of the refrigerant is transferred to the heater core 47 for the purpose of heating the interior of the vehicle.

[0137] 23A, the refrigerant heated by the inverter 43 is transported to the battery 41 via the first valve V1 as indicated by the dashed line, and then returns from the battery 41 to the inverter 43 via the second valve V2, the pump P2, and the ECU 53. This allows the battery 41 to be warmed up.

[0138] In addition, separate from the above flow path, the heat refrigerant heated by the motor 45 returns to the motor 45 via the second valve V2, the pump P3, the first valve V1, the water-cooled condenser 25, the heater core 47, and the first valve V1, as shown by the solid line.

[0139] In addition to the above flow path, the heat refrigerant returns from the chiller 27 through the pump P4, the third valve V3, the radiator 49, and the third valve V3 to the chiller 27, as indicated by the dashed dotted line. As indicated by thin dashed lines, the flow path connecting the first valve V1 and the third valve V3 and the flow path connecting the third valve V3 and the second valve V2 are closed circuits. The pump P1 is stopped.

[0140] <Example 18> As shown in the two dashed boxes in Figure 24B, a case will be described in which the heat refrigerant is heated by heat generated by the inverter 43 and transported to the battery 41 for the purpose of warming up the battery 41, and the heat refrigerant is heated by heat generated by the motor 45 and the heat of the refrigerant is transferred to the heater core 47 via the chiller 27 and the water-cooled condenser 25 for the purpose of heating the interior of the vehicle.

[0141] 24A, the refrigerant heated by the inverter 43 is transported to the battery 41 via the first valve V1 as indicated by the dashed line, and then returns from the battery 41 to the inverter 43 via the second valve V2, the pump P2, and the ECU 53. This allows the battery 41 to be warmed up.

[0142] In addition to the above flow path, the heat refrigerant heated by the motor 45 returns to the motor 45 via the second valve V2, the third valve V3, the chiller 27, the pump P4, the third valve V3, and the first valve V1, as shown by the solid line.

[0143] In addition, separate from the above flow path, the heat refrigerant returns to the water-cooled condenser 25 via the heater core 47, the first valve V1, the pump P1, the third valve V3, the second valve V2, the pump P3, and the first valve V1, as shown by the dashed double-dotted line.

[0144] With the above-mentioned configuration, the temperature of the chiller 27 rises due to the heat refrigerant heated by the motor 45, and the temperature of the heat refrigerant flowing through the refrigerant circuit 5 side of the chiller 27 rises. Therefore, the temperature of the heat refrigerant flowing through the refrigerant circuit 5 side of the water-cooled condenser 25 also rises, and the temperature of the heater core 47 also rises. Therefore, the air inside the vehicle can be heated by this heater core 47.

[0145] As indicated by a thin dashed line, the flow path connecting the third valve V3 and the radiator 49 is a closed circuit. <Example 19> As shown in the two dashed frames in Figure 25B, a case will be described in which the heat refrigerant is heated by heat generated by the inverter 43 and transported to the battery 41 for the purpose of warming up the battery 41, and the heat refrigerant is heated by heat generated by the motor 45 and transported to the radiator 49 for the purpose of defrosting the radiator 49.

[0146] 25A, the refrigerant heated by the inverter 43 is transported to the battery 41 via the first valve V1 as indicated by the dashed line, and then returns from the battery 41 to the inverter 43 via the second valve V2, the pump P2, and the ECU 53. This allows the battery 41 to be warmed up.

[0147] In addition to the above flow path, the refrigerant heated by the motor 45 returns to the motor 45 via the second valve V2, the third valve V3, the radiator 49, the third valve V3, the second valve V2, the pump P3, and the first valve V1, as shown by the solid line. This allows defrosting in the radiator 49.

[0148] In addition to the above flow path, the heat refrigerant returns to the water-cooled condenser 25 from the water-cooled condenser 25 via the heater core 47, the first valve V1, the pump P1, the third valve V3, and the first valve V1, as shown by the two-dot chain line.

[0149] As indicated by a thin dashed line, the flow path from the third valve V3 through the chiller 27 and the pump P4 to the third valve V3 forms a closed circuit.

[0150] 26A, the refrigerant heated by the inverter 43 is transported to the battery 41 via the first valve V1 as indicated by the dashed line, and then returns from the battery 41 to the inverter 43 via the second valve V2, the pump P2, and the ECU 53. This allows the battery 41 to be warmed up.

[0151] In addition to the above flow paths, the heat refrigerant heated by the motor 45 returns to the motor 45 via the second valve V2, the pump P3, and the first valve V1, as shown by the solid line. This allows heat to be stored in the motor 45.

[0152] In addition to the above flow path, the heat refrigerant returns to the water-cooled condenser 25 from the water-cooled condenser 25 via the heater core 47, the first valve V1, the pump P1, the third valve V3, and the first valve V1, as shown by the two-dot chain line.

[0153] In addition to the above flow path, the heat refrigerant returns from the chiller 27 through the pump P4, the third valve V3, the radiator 49, and the third valve V3 to the chiller 27, as indicated by the dashed dotted line. <Example 21> As shown in the two dashed frames in FIG. 27B, a case will be described in which the heat refrigerant is heated by the heat generated by the inverter 43 and transported to the radiator 49 for the purpose of defrosting the radiator 49, and the heat refrigerant is heated by the heat generated by the motor 45 and transported to the heater core 47 for the purpose of heating the interior of the vehicle.

[0154] 27A, the refrigerant heated by the inverter 43 returns to the inverter 43 via the first valve V1, the pump P1, the third valve V3, the radiator 49, the third valve V3, the second valve V2, the pump P2, and the ECU 53, as indicated by the dashed line. This causes the radiator 49 to be defrosted.

[0155] In addition to the above flow paths, the refrigerant heated by the motor 45 returns to the motor 45 via the second valve V2, the pump P3, the first valve V1, the water-cooled condenser 25, the heater core 47, and the first valve V1, as shown by the solid line. This allows the heater core 47 to heat the vehicle interior.

[0156] In addition to the above flow path, the heat refrigerant returns to chiller 27 via pump P4, third valve V3, first valve V1, battery 41, second valve V2, and third valve V3, as shown by the dashed double-dashed line.

[0157] <Example 22> As shown in the two dashed frames in FIG. 28B, a case will be described in which the heat generated by the inverter 43 heats the heat refrigerant and transports it to the radiator 49 for the purpose of defrosting the radiator 49, and the heat generated by the motor 45 heats the heat refrigerant and transfers the heat of the heat refrigerant to the heater core 47 via the chiller 27 and the water-cooled condenser 25 for the purpose of heating the interior of the vehicle.

[0158] 28A, the refrigerant heated by the inverter 43 returns to the inverter 43 via the first valve V1, the pump P1, the third valve V3, the radiator 49, the third valve V3, the second valve V2, the pump P2, and the ECU 53, as indicated by the dashed line. This causes the radiator 40 to be defrosted.

[0159] In addition to the above flow path, the heat refrigerant heated by the motor 45 returns to the motor 45 via the second valve V2, the third valve V3, the chiller 27, the pump P4, the third valve V3, and the first valve V1, as shown by the solid line.

[0160] In addition, separate from the above flow path, the heat refrigerant returns to the water-cooled condenser 25 via the heater core 47, the first valve V1, the battery 41, the second valve V2, the pump P3, and the first valve V1, as shown by the dashed double-dotted line.

[0161] With the above-mentioned configuration, the temperature of the chiller 27 rises due to the heat refrigerant heated by the motor 45, and the temperature of the heat refrigerant flowing through the refrigerant circuit 5 side of the chiller 27 rises. Therefore, the temperature of the heat refrigerant flowing through the refrigerant circuit 5 side of the water-cooled condenser 25 also rises, and the temperature of the heater core 47 also rises. Therefore, the air inside the vehicle can be heated by this heater core 47.

[0162] <Example 23> As shown in the two dashed frames in Figure 29B, a case will be described in which the heat refrigerant is heated by heat generated by inverter 43 and transported to radiator 49 for the purpose of defrosting radiator 49, and the heat refrigerant is heated by heat generated by motor 45 and transported to battery 41 for the purpose of warming up battery 41.

[0163] 29A, the refrigerant heated by the inverter 43 returns to the inverter 43 via the first valve V1, the pump P1, the third valve V3, the radiator 49, the third valve V3, the second valve V2, the pump P2, and the ECU 53, as indicated by the dashed line. This causes the radiator 49 to be defrosted.

[0164] Separately from the above flow path, the refrigerant heated by the motor 45 returns to the motor 45 via the second valve V2, the pump P3, the first valve V1, the battery 41, the second valve V2, the third valve V3, the first valve V1, the water-cooled condenser 25, the heater core 47, and the first valve V1, as shown by the solid line. This allows the battery 41 to be warmed up.

[0165] As indicated by a thin dashed line, the flow path from the third valve V3 through the chiller 27 and the pump P4 to the third valve V3 forms a closed circuit. The pump P4 is stopped. <Example 24> As shown in the two dashed frames in Figure 30B, a case will be described in which the heat refrigerant is heated by heat generated by inverter 43 and transported to radiator 49 for the purpose of defrosting radiator 49, and the heat refrigerant is heated by heat generated by motor 45 and transported to motor 45 for the purpose of storing heat in motor 45.

[0166] 30A, the refrigerant heated by the inverter 43 returns to the inverter 43 via the first valve V1, the pump P1, the third valve V3, the radiator 49, the third valve V3, the second valve V2, the pump P2, and the ECU 53, as indicated by the dashed line. This causes the radiator 49 to be defrosted.

[0167] In addition to the above flow paths, the heat refrigerant heated by the motor 45 returns to the motor 45 via the second valve V2, the pump P3, and the first valve V1, as shown by the solid line. This allows heat to be stored in the motor 45.

[0168] In addition, separate from the above flow path, the heat refrigerant returns to the water-cooled condenser 25 via the heater core 47, the first valve V1, the battery 41, the second valve V2, the third valve V3, the chiller 27, the pump P4, the third valve V3, and the first valve V1, as shown by the dotted line.

[0169] <Example 25> As shown in the dashed frame in FIG. 31B, a case will be described in which the heat refrigerant is heated by the heat generated by the inverter 43 and the motor 45, and the heat refrigerant is transported to the heater core 47 for the purpose of heating the interior of the vehicle.

[0170] 31A, the refrigerant heated by the inverter 43 reaches the motor 45 via the first valve V1 as indicated by the dashed line, and the refrigerant heated by the motor 45 returns to the inverter 43 via the second valve V2, the third valve V3, the first valve V1, the water-cooled condenser 25, the heater core 47, the first valve V1, the pump P1, the third valve V3, the second valve V2, the pump P2, and the ECU 53. This heats the heater core 47, thereby heating the interior of the vehicle.

[0171] In addition to the above flow path, the heat refrigerant returns to the battery 41 from the battery 41 via the second valve V2, the pump P3, and the first valve V1, as indicated by the solid line. <Example 26> As shown within the dashed frame in Figure 32B, a thermal refrigerant is heated by heat generated by an inverter 43 and a motor 45, and the heat of the thermal refrigerant is transferred to a heater core 47 via a chiller 27 and a water-cooled condenser 25 for the purpose of heating the interior of the vehicle.

[0172] 32A, the refrigerant heated by the inverter 43 reaches the motor 45 via the first valve V1 as indicated by the dashed line, and the refrigerant heated by this motor 45 returns to the inverter 43 via the second valve V2, the third valve V3, the chiller 27, the pump P4, the third valve V3, the second valve V2, the pump P2, and the ECU 53. This causes the chiller 27 to be heated.

[0173] In addition to the above flow path, the heat refrigerant returns to the water-cooled condenser 25 from the water-cooled condenser 25 via the heater core 47, the first valve V1, the pump P1, the third valve V3, and the first valve V1, as shown by the two-dot chain line.

[0174] With the above-mentioned configuration, the temperature of the chiller 27 rises due to the heat refrigerant heated by the inverter 43 and the motor 45, and the temperature of the heat refrigerant flowing through the refrigerant circuit 5 side of the chiller 27 rises. As a result, the temperature of the heat refrigerant flowing through the refrigerant circuit 5 side of the water-cooled condenser 25 also rises, and the temperature of the heater core 47 also rises. Therefore, the heater core 47 can heat the air inside the vehicle.

[0175] In addition to the above flow path, the heat refrigerant returns to the battery 41 from the battery 41 via the second valve V2, the pump P3, and the first valve V1, as indicated by the solid line. <Example 27> As shown in the dashed frame in FIG. 33B, a case will be described in which the thermal refrigerant is heated by heat generated by inverter 43 and motor 45, and transported to battery 41 for the purpose of warming up battery 41.

[0176] 33A, the refrigerant heated by the inverter 43 reaches the motor 45 via the first valve V1 as indicated by the dashed line, and the refrigerant heated by the motor 45 returns to the inverter 43 via the second valve V2, the pump P3, the first valve V1, the battery 41, the second valve V2, the pump P2, and the ECU 53. This allows the battery 41 to be warmed up.

[0177] In addition to the above flow path, the heat refrigerant returns to the water-cooled condenser 25 from the water-cooled condenser 25 via the heater core 47, the first valve V1, the pump P1, the third valve V3, and the first valve V1, as shown by the two-dot chain line.

[0178] In addition to the above flow path, the heat refrigerant returns from the chiller 27 through the pump P4, the third valve V3, the radiator 49, and the third valve V3 to the chiller 27, as indicated by the dashed dotted line. <Example 28> As shown in the dashed frame in FIG. 34B, a case will be described in which the thermal refrigerant is heated by heat generated by inverter 43 and motor 45, and transported to radiator 49 for the purpose of defrosting radiator 49.

[0179] 34A, the refrigerant heated by the inverter 43 reaches the motor 45 via the first valve V1 as indicated by the dashed line, and the refrigerant heated by the motor 45 returns to the inverter 43 via the second valve V2, the third valve V3, the radiator 49, the third valve V3, the second valve V2, the pump P2, and the ECU 53. This causes the radiator 49 to be defrosted.

[0180] In addition to the above flow path, the heat refrigerant returns to the water-cooled condenser 25 from the water-cooled condenser 25 via the heater core 47, the first valve V1, the pump P1, the third valve V3, and the first valve V1, as shown by the two-dot chain line.

[0181] As indicated by a thin dashed line, the flow path from the chiller 27, via the pump P4 and the third valve V3, back to the chiller 27 forms a closed circuit. The pump P4 is stopped. [1-5. Control processing] Next, each control process performed by the arithmetic processing unit 61 will be described.

[0182] [1-5-1. Main processing] This process is a process for controlling the temperature of the object to be heated to a target temperature, and is performed at predetermined time intervals.

[0183] As shown in the flowchart of FIG. 35, first, in step (hereinafter, S), the state of the vehicle 1 is read based on detection signals from each sensor, etc. In the next step S110, it is determined whether or not there is a request to increase the temperature of the target to be increased. If the determination is affirmative, the process proceeds to S120, whereas if the determination is negative, the process is temporarily terminated.

[0184] For example, in winter, when the environmental temperature (i.e., the temperature around the vehicle 1) is low and desirable performance cannot be obtained when various components (e.g., the battery 41, heater core 47, radiator 49, motor 45, etc.) are operating, those components are designated as targets for heating, and a heating request is output to raise the temperature of each target for heating.

[0185] For example, if the environmental temperature is 5° C. and the temperature preferable for the operation of the object to be heated is 10° C., a temperature increase request is output to increase the temperature of the object to be heated to 10° C. That is, a temperature increase request is output to the calculation processing unit 61 itself based on the environmental temperature so as to make the object to be heated reach a predetermined target temperature.

[0186] In S120, the required heat quantity Q is calculated. That is, the heat quantity Q required to raise the temperature of the object to be heated from the current temperature to the target temperature is calculated. For example, if the current temperature is T1°C, the target temperature is T2°C, and the heat capacity of the object to be heated is NQ, the temperature difference to be increased is (T2-T1)°C, so the required heat quantity Q is "temperature difference (T2-T1)°C x heat capacity NQ".

[0187] In the next step S130, the inverter temperature rise flag F I This inverter temperature rise flag F I is a flag indicating the components to be heated when the inverter 43 is heated. For example, the inverter temperature raising flag F I When the value is 1, 2, 3, 4, or 5, the objects to be heated are the heater core 47, the chiller 27, the battery 41, the radiator 49, and the motor 45, respectively.

[0188] In the next step S140, the MG temperature rise flag F MThis MG temperature rise flag F M is a flag indicating the component to be heated when the motor 45 is used to heat the component. For example, the MG temperature rise flag F M When the temperature is 10, 20, 30, 40, or 50, the objects to be heated are the heater core 47, the chiller 27, the battery 41, the radiator 49, and the motor 45, respectively.

[0189] In the next step S150, the temperature rise control device selection flag F h This temperature rise control device selection flag F h is a flag indicating the device that performs the temperature rise control. For example, the temperature rise control device selection flag F h When the value is 1, it indicates that the inverter 43 performs temperature increase control.

[0190] In the next step S160, the inverter temperature rise flag F I and MG temperature rise flag F M and temperature rise control device selection flag F h Based on this, the valve angle (that is, the rotation angle) which is the opening degree of the first valve V1 and the second valve V2 is calculated.

[0191] Here, the inverter temperature rise flag F I and MG temperature rise flag F M and temperature rise control device selection flag F h The processing procedure for the above will be described. The process is performed, for example, in the order of "(1) selection of a target for heating" and "(2) prioritization of heating requests." Prioritization is determined based on the required heat amount and quick heating.

[0192] Specifically, for example, in the case of the operation example 11 shown in Fig. 17, (1) the target for temperature increase is "heater core 47, battery 41". Also, (2) the priority of the temperature increase request is "battery 41 < heater core 47" (i.e., in consideration of quick heating, the heater core 47 has a higher priority than the battery 41).

[0193] Therefore, the inverter temperature rise flag F I The heater core 47 with high quick heating is set to "1", and the MG temperature rise flag FM selects the remaining battery "30" that requires warming up, so the temperature rise control device selection flag F h is the inverter temperature rise flag F I and MG temperature rise flag F M Therefore, the number "3" is selected.

[0194] Also, for example, in the case of a situation or device requiring quick heating in terms of responsiveness, such as when starting the vehicle 1 at low temperatures (for example, when warming up the motor 45 at startup), heat can be generated by at least the inverter 43. Alternatively, when it is important to use heat storage with a large amount of heat (for example, when heating the battery 41 throughout the entire charging range), heat can be generated by the motor 45 or by the inverter 43 and the motor 45.

[0195] Figure 36 shows the temperature rise control device selection flag F h , inverter temperature rise flag F I and MG temperature rise flag F M The relationship between the total value of V1, the valve angle of the first valve V1, the valve angle of the second valve V2, etc. is shown.

[0196] The valve angle of the third valve V3 is set according to the configuration of the flow path in each operation example, etc. Fig. 36 shows the valve angle of the third valve V3. Returning to Fig. 35, in S170, the valve angle of the first valve V1 and the valve angle of the second valve V2 are controlled. At the same time, the valve angle of the third valve V3 is also controlled.

[0197] In the next step S180, the duty control of the pump P is performed. That is, the pump P is operated to transport the heat refrigerant in the pipe H in a predetermined direction. In the next step S190, it is determined whether the temperature of the object to be heated has exceeded the target temperature. If the determination is affirmative, the process ends. If the determination is negative, the process returns to step S110.

[0198] [1-5-2. Each process] Next, processing other than the main processing will be described. This processing is performed at predetermined time intervals.

[0199] <Processing example 1> The present processing example 1 shows an example of processing when temperature increase control is performed by the inverter 43 (for example, operation example 1, etc.).

[0200] As shown in the flowchart of Fig. 37, in S200, since the temperature of the object to be heated (for example, heater core 47) is low, it is determined whether or not there is a temperature increase request to increase the temperature of the object to be heated. If the answer is YES, the process proceeds to S210, whereas if the answer is NO, the process is temporarily terminated.

[0201] In S210, temperature increase control is performed to generate heat in the inverter 43. In the next S220, each valve V (e.g., the first valve V1) is controlled (i.e., the valve angle is adjusted) so that the thermal refrigerant is supplied from the inverter 43 to the target to be heated (e.g., the heater core 47), and the process ends. At this time, the pump P (e.g., the pump P2) required for transporting the thermal refrigerant to the target to be heated is also operated.

[0202] According to the present process example 1, the thermal refrigerant heated by the heat generated by the inverter 43 can increase the temperature of the object to be heated. Heat may be generated by the motor 45 instead of the inverter 43. In this case, the inverter 43 in each step of the flowchart in Fig. 37 may be replaced with the motor 45. Therefore, the temperature of the object to be heated can be increased by the thermal refrigerant heated by the heat generated by the motor 45.

[0203] <Processing example 2> The present processing example 2 shows an example of processing when the temperature increase control is performed by the motor 45 (for example, operation example 8, etc.).

[0204] 38, in S300, since the temperature of another target (e.g., battery 41) other than the target to be heated due to heat generation by inverter 43 is low, it is determined whether or not there is a temperature increase request to increase the temperature of the other target to be heated. If the determination here is affirmative, the process proceeds to S310, whereas if the determination here is negative, this process is temporarily terminated.

[0205] In S310, temperature increase control is performed to generate heat by the motor 45. In the next S320, each valve V (e.g., the second valve V2) is controlled (i.e., the valve angle is adjusted) so that the motor 45 supplies the heat refrigerant to another target to be heated (e.g., the battery 41), and the process ends. At this time, the pump P (e.g., pump P3) required to transport the heat refrigerant to the target to be heated is also operated.

[0206] According to the present process example 2, the heat medium heated by the heat generated by the motor 45 can increase the temperature of the object to be heated. <Processing example 3> The present process example 3 shows an example of a process (for example, operation example 11, etc.) in the case where the inverter 43 and the motor 45 are used to increase the temperature of the object to be heated.

[0207] 39, in S400, it is determined whether or not the vehicle 1 is started (for example, when the start switch of the vehicle 1 is turned on) or the battery 41 is being charged. If the determination here is affirmative, the process proceeds to S410, whereas if the determination here is negative, this process is temporarily terminated.

[0208] In S410, temperature increase control is performed to generate heat in the inverter 43. In the next step 420, each valve V (e.g., first to third valves V1 to V3) is controlled (i.e., the valve angle is adjusted) so that the thermal refrigerant is supplied from the inverter 43 to the target to be heated (e.g., heater core 47). At this time, a pump P (e.g., pumps P1 and P2) required for transporting the thermal refrigerant to the target to be heated is also operated.

[0209] In the next S430, it is determined whether the temperature of the motor 45 is equal to or higher than a predetermined threshold value. In other words, it is determined whether the temperature of the motor is suitable for operation. If the answer is YES, the process proceeds to S440, whereas if the answer is NO, the process proceeds to S460.

[0210] In S440, the motor 45 is in a warm-up state. Therefore, each valve V (e.g., the first and second valves V1 and V2) are controlled (i.e., the valve angle is adjusted) so that the motor 45 in the warm-up state supplies the thermal refrigerant to the target to be heated (e.g., the battery 41), and this process is temporarily terminated. At this time, the pump P (e.g., the pump P3) required for transporting the thermal refrigerant to the target to be heated is also operated.

[0211] On the other hand, in S450, which is reached after a negative determination in S430, a closed circuit of the motor 45 is formed, and the present process is temporarily terminated. According to the present process example 3, the temperature of the object to be heated can be increased by the heat refrigerant supplied from the inverter 43 under temperature increase control and the motor 45 in a warmed-up state.

[0212] <Processing example 4> The present processing example 4 shows an example of processing in which temperature increase control is performed by the inverter 43 and the motor 45 when there is one object to be heated.

[0213] 40, in S500, it is determined whether the temperature of the motor 45 is below a predetermined threshold value. In other words, it is determined whether the temperature of the motor 45 is a low temperature that is not suitable for heating the thermal refrigerant. If the determination here is affirmative, the process proceeds to S510, whereas if the determination here is negative, the process proceeds to S530.

[0214] In S510, since the motor 45 is at a low temperature, temperature increase control by heat generation from the inverter 43 is performed. In the next step S520, the inverter 43 controls each valve V to supply the heat refrigerant to the object to be heated, and the process ends. At this time, the pump P required for transporting the heat refrigerant to the object to be heated is also operated.

[0215] On the other hand, in S530, which is reached after a negative determination in S500, the temperature of the motor 45 is not low (that is, the temperature is not low so that it is difficult for the temperature to increase), so temperature increase control is performed by generating heat from the motor 45.

[0216] In the next step S540, the valves V are controlled so that the motor 45 supplies the heat refrigerant to the object to be heated, and the process ends. At this time, the pump P required for transporting the heat refrigerant to the object to be heated is also operated.

[0217] According to the present process example 4, the heat generated by the inverter 43 and the motor 45 can be utilized to appropriately increase the temperature of the object to be heated (for example, quickly by the inverter 43). <Processing example 5> The present processing example 5 shows an example of processing in which the inverter 43 and the motor 45 perform temperature increase control.

[0218] 41, in S600, it is determined whether or not the warm-up of the battery 41 and the motor 45 has been completed. If the determination here is affirmative, the process proceeds to S610, whereas if the determination here is negative, the process is temporarily terminated.

[0219] In S610, heat is generated by the inverter 43 and the motor 45, and each valve V is controlled so that the thermal refrigerant is supplied from the inverter 43 and the motor 45 to the heater core 47 or the chiller 27, and this process ends once. At this time, the pump P necessary for transporting the thermal refrigerant to the object to be heated is also operated.

[0220] According to the present processing example 5, when the warm-up of the battery 41 and the motor 45 is completed, the heat generated by the inverter 43 and the motor 45 can be used to increase the temperature of the object to be heated. <Processing example 6> The present process example 6 shows an example of a process in which control is performed to suppress a decrease in temperature of a component connected to the pipe H of the temperature control circuit 7 and to which a thermal refrigerant is supplied. This component has a function of storing heat supplied by the thermal refrigerant in itself. Hereinafter, such a component may be simply referred to as a heat storage element.

[0221] As shown in the flowchart of Fig. 42, in S700, it is determined whether the vehicle 1 is stopped (for example, when the vehicle is parked) or the system is stopped (for example, when the operation of the vehicle control device 9 is stopped). If a positive determination is made here, the process proceeds to S710, whereas if a negative determination is made, this process is temporarily terminated. Note that an example of a state when the system is stopped is when the driver has left the vehicle 1 and locked the key.

[0222] In S710, the flow path connected to the heat storage element (for example, the battery 41) is closed, and this process ends once. According to the present processing example 6, when the vehicle 1 is stopped or the system is stopped, it is possible to suppress a decrease in the temperature of the heat storage element.

[0223] Here, examples of the heat storage element include a battery 41, an inverter 43, a motor 45, a heater core 47, a radiator 49, and the like. <Processing example 7> The present process example 7 shows a process example (for example, operation example 3, etc.) in the case where control is performed to store heat in a heat storage element.

[0224] As shown in the flowchart of Fig. 43, in S800, it is determined whether the temperature of the heat storage element (for example, the battery 41) is below a predetermined temperature, which is undesirable for operation. If the determination here is affirmative, the process proceeds to S810, whereas if the determination here is negative, the process is temporarily terminated.

[0225] In S810, a temperature increase control for generating heat by the inverter 43 or the motor 45 is performed. In the next step S820, each valve V is controlled so as to supply the heat refrigerant from the inverter 43 or the motor 45 to the heat storage element, and the process ends. At this time, the pump P required for transporting the heat refrigerant to the heat storage element is also operated.

[0226] According to this processing example 7, the temperature of the heat storage element can be increased. <Processing example 8> The present processing example 8 shows an example of processing when the vehicle 1 is started (for example, operation example 1, etc.).

[0227] As shown in the flowchart of Fig. 44, in S900, it is determined whether or not the vehicle 1 is being started. If the determination here is affirmative, the process proceeds to S910, whereas if the determination here is negative, the process is temporarily terminated. In S910, a temperature increase control for generating heat by the inverter 43 is performed.

[0228] In the next step S920, the valve V is controlled to connect the inverter 43 and the heater core 47. In the next S930, the flow path of the motor 45 is closed or the motor 45 and the battery 41 are connected, and the process ends.

[0229] According to this process example 8, the inside of the vehicle can be quickly warmed up at the time of starting. Also, a drop in the temperatures of the motor 45 and the battery 41 can be suppressed. <Processing example 9> The present processing example 9 shows a process (for example, operation example 3, etc.) in the case where the battery 41 of the vehicle 1 is charged by a charger installed outside the vehicle 1.

[0230] 45, in S1000, it is determined whether or not the destination of the vehicle 1 is a charger based on a signal from the navigation device 11. If the determination here is affirmative, the process proceeds to S1010, whereas if the determination here is negative, the process is temporarily terminated.

[0231] In S1010, a temperature increase control for generating heat by the inverter 43 and / or the motor 45 is performed. In the next step S1020, the valve V is controlled to connect the inverter 43 and the motor 45 that have generated heat to the battery 41. At this time, the pump P required to transport the heat refrigerant to the battery 41 is also operated.

[0232] According to this processing example 9, when the battery 41 is charged by a charger, the temperature of the battery 41 can be increased to a temperature suitable for charging. <Processing example 10> The present processing example 10 shows processing for warming up the battery 41 (for example, operation example 3, etc.).

[0233] As shown in the flowchart of Figure 46, in S1100, when the vehicle is stopped, it is determined whether or not there is a request to warm up the battery 41. If the determination here is affirmative, the process proceeds to S1110, whereas if the determination here is negative, the process is temporarily terminated.

[0234] In S1110, a temperature increase control for generating heat by the inverter 43 is performed. In the next step S1120, the valve V is controlled so as to connect the inverter 43 that has been heated to the battery 41. At this time, the pump P required for transporting the heat refrigerant to the battery 41 is also operated.

[0235] In the next S1130, it is determined whether or not the warm-up of the battery 41 has been completed. If the determination here is affirmative, the process proceeds to S1140, whereas if the determination here is negative, the process returns to S1110. In the next step S1140, the flow path of the battery 41 is closed, and the process ends.

[0236] According to this processing example 10, when the temperature of the battery 41 is low while the vehicle is stopped, the temperature of the battery 41 can be raised quickly. [1-6. Experimental Example] Next, an experimental example performed to confirm the effects of the present disclosure (eg, the effects of the first embodiment) will be described.

[0237] 47A shows an example of operation in a heating priority mode in which heating has priority over heating the battery 41. Note that HP is an abbreviation for heat pump. In this heating priority mode, since heating is prioritized, heat is generated by the inverter 43 to heat the heat refrigerant, and the heat generated is transported to the chiller 27 to heat the chiller 27. The heat refrigerant in the refrigerant circuit 5 that receives heat from the chiller 27 heats the water-cooled condenser 25. The water-cooled condenser 25 heats the heat refrigerant in the temperature control circuit 7, and the heat refrigerant is transported to the heater core 47 to heat the heater core 47 and heat the interior of the vehicle.

[0238] In the heating priority mode, when the temperature of the battery 41 is to be increased, the hot refrigerant is supplied from the heater core 47 to the motor 45, and the hot refrigerant is heated by the motor 45. The hot refrigerant heated by the motor 45 is supplied to the battery 41 and heats the battery 41.

[0239] FIG. 47B shows an example of operation in the battery priority mode in which heating of the battery 41 is prioritized over room heating. In this battery priority mode, since priority is given to heating the battery 41, heat is generated by the inverter 43 to heat the thermal refrigerant, and the heated thermal refrigerant is transported to the battery 41 to heat it.

[0240] In the battery priority mode, the temperature of the hot refrigerant in the radiator 49 is increased by utilizing outside air, and the hot refrigerant with increased temperature is transported to the chiller 27. The hot refrigerant in the refrigerant circuit 5 that has received heat in the chiller 27 heats the water-cooled condenser 25. The water-cooled condenser 25 heats the hot refrigerant in the temperature control circuit 7, and the hot refrigerant is transported to the heater core 47 to heat the heater core 47 and heat the interior of the vehicle. The hot refrigerant is then transported from the heater core 47 to the motor 45, and is heated by the heat generated by the motor 45.

[0241] 48A shows the results of investigating changes in temperature rise of battery 41 in heating priority mode, battery priority mode, and a comparative example. Note that the conventional example is a conventional example in which first valve V1 is not provided between inverter 43 and motor 45.

[0242] As is clear from Fig. 48A, the temperature of the battery 41 increased more quickly in the heating priority mode and the battery priority mode compared to the comparative example. Also, the temperature of the battery 41 increased more quickly in the battery priority mode compared to the heating priority mode.

[0243] FIG. 48B shows the results of investigating changes in temperature rise inside the vehicle (that is, the air outlet portion of the cabin) in the heating-priority mode, the battery-priority mode, and a comparative example. As is clear from Fig. 48B, the cabin temperature rose more quickly in the heating priority mode and the battery priority mode compared to the comparative example. Also, the cabin temperature rose more quickly in the heating priority mode compared to the battery priority mode.

[0244] [1-7.Effects] According to the first embodiment, the following effects can be obtained. (1a) In this first embodiment, the temperature control circuit 7 of the vehicle system 3 includes an inverter 43, a motor 45, a piping H for a thermal refrigerant arranged to connect the inverter 43 and the motor 45 in series, and a first valve V1 arranged in the piping H and configured to be able to switch the flow path of the thermal refrigerant.

[0245] The first valve V1 is connected to one or more pipes H in addition to the pipe H leading to the inverter 43 and the pipe H leading to the motor 45, and this first valve V1 has a configuration that can be switched to transport the heat refrigerant supplied from the upstream side to the downstream side of the first valve V1 to at least one pipe H of the multiple pipes H on the downstream side.

[0246] In the vehicle system 3, the inverter 43 and the motor 45 can be subjected to temperature rise control for generating heat (i.e., generating heat) by passing a current for the purpose of generating heat. Therefore, when at least one of the inverter 43 and the motor 45 is subjected to temperature rise control, the first valve V1 can be controlled to transport the thermal refrigerant from at least one of the inverter 43 and the motor 45 subjected to temperature rise control to a destination (i.e., a target for temperature rise) arranged downstream of at least one of the inverter 43 and the motor 45 subjected to temperature rise control.

[0247] With such a configuration, in the first embodiment, various performances of the vehicle 1 can be improved by effectively utilizing heat generated by devices in the vehicle 1 that are capable of generating heat (i.e., capable of generating heat).

[0248] That is, since the inverter 43 and the motor 45 are each capable of generating heat (i.e., raising the temperature by applying a current), the temperature of the heat refrigerant supplied to the inverter 43 and the motor 45 can be raised by generating heat from the inverter 43 and the motor 45. Therefore, by switching the supply destination of the heated heat refrigerant by the first valve V1, the heat of the heat refrigerant can be effectively utilized to efficiently raise the temperature of the device to be heated.

[0249] (1b) In the first embodiment, the circuit system 13 of the vehicle system 3 can include the following components: an inverter 43, a motor 45, a battery 41, a chiller 27, a heater core 47, a radiator 49, a first valve V1, and a pump P. Each of these components can be configured to be connected to a pipe H through which a heat refrigerant flows.

[0250] Moreover, the first valve V1 can be provided in the pipe H connecting the heat refrigerant outlet side of the inverter 43 and the heat refrigerant inlet side of the motor 45, or can be provided in the pipe H connecting the heat refrigerant outlet side of the motor 45 and the heat refrigerant inlet side of the inverter 43. Furthermore, the first valve V1 can be configured to be connected to at least one of the battery 41, the chiller 27, the heater core 47, and the radiator 49 via the pipe H for the heat refrigerant.

[0251] Furthermore, the flow path of the heat refrigerant can be switched by controlling the operation of the first valve V1 so that the heat refrigerant that has passed through the temperature-controlled inverter 43 or motor 45 is transported to at least one of the battery 41, chiller 27, heater core 47, radiator 49, and motor 45.

[0252] (1c) In the first embodiment, it is possible to determine whether or not there is a temperature increase request for at least one of the temperature increase targets among the battery 41, the chiller 27, the heater core 47, and the radiator 49. Furthermore, when it is determined that there is a temperature increase request, it is possible to perform temperature increase control of the inverter 43. Furthermore, when performing temperature increase control of the inverter 43, it is possible to switch the flow path of the heat refrigerant by the first valve V1 so that the heat refrigerant that has passed through the inverter 43 is transported to the temperature increase target. With this configuration, it is possible to quickly heat the temperature increase target.

[0253] (1d) In the first embodiment, the heat refrigerant that has passed through the temperature-controlled inverter 43 can be transported through a predetermined flow path to at least one of the battery 41, the chiller 27, the heater core 47, and the radiator 49. In addition, the flow path of the heat refrigerant can be switched by the first valve V1 or the like so that the heat refrigerant that has passed through the temperature-controlled motor 45 can be transported through a flow path different from the predetermined flow path of the heat refrigerant that has passed through the inverter 43 to at least one of the battery 41, the chiller 27, the heater core 47, and the radiator 49.

[0254] (1e) In the first embodiment, a second valve V2 or the like different from the first valve V1, and a pipe H connecting the outlet side of the motor 45 for the heat refrigerant and the second valve V2 or the like can be provided. Then, it can be determined whether or not there is a temperature increase request from a temperature increase target other than the temperature increase target to which the heat refrigerant that has passed through the temperature increase-controlled inverter 43 is transported (i.e., another temperature increase target). If it is determined that there is a temperature increase request from the other temperature increase target, the temperature increase control of the motor 45 can be performed. Furthermore, when the temperature increase control of the motor 45 is performed, the flow path can be switched by the second valve V2 or the like so that the heat refrigerant that has passed through the motor 45 is transported to the other temperature increase target.

[0255] With this configuration, the heat medium heated by the motor 45 can be used to increase the temperature of another object to be heated. (1f) In the first embodiment, when starting the vehicle 1 or charging the battery 41 of the vehicle 1, the inverter 43 is controlled to be heated, and the flow path of the heat refrigerant that has passed through the inverter 43 can be switched by the first valve V1 so that the heat refrigerant that has passed through the motor 45 is transported to the object to be heated. Furthermore, when the motor 45 is equal to or higher than a predetermined temperature threshold, the flow path of the heat refrigerant can be switched by the first valve V1, the second valve V2, etc. so that the heat refrigerant that has passed through the motor 45 is transported to the object to be heated. Alternatively, when the motor 45 is below the predetermined temperature threshold, the flow path of the heat refrigerant can be switched by the first valve V1, the second valve V2, etc. so that the flow path of the heat refrigerant becomes a closed circuit flow path for the motor 45 alone.

[0256] With this configuration, when starting the vehicle 1 or charging the battery 41, the object to be heated can be heated quickly, and appropriate measures such as heating the object to be heated can be taken depending on the state of the motor 45.

[0257] (1g) In the first embodiment, when there is one target to be heated, if the motor 45 is below a predetermined temperature threshold, the inverter 43 performs temperature rise control, and the first valve V1 can switch the flow path of the heat refrigerant so that the heat refrigerant that has passed through the inverter 43 is connected to the target to be heated. Also, when there is one target to be heated, if the motor 45 is equal to or higher than a predetermined temperature threshold, the motor 45 performs temperature rise control, and the first valve V1, the second valve V2, etc. can switch the flow path of the heat refrigerant so that the heat refrigerant that has passed through the motor 45 is transported to the target to be heated.

[0258] With this configuration, the operation of the inverter 43 and the motor 45 can be controlled in accordance with the temperature of the motor 45, and the object to be heated can be appropriately heated. (1h) In this first embodiment, when it is determined that the battery 41 and the motor 45 have completed warming up, the flow path of the heat refrigerant can be switched using the first valve V1 or the second valve, etc., so that the heat refrigerant that has passed through the temperature-controlled inverter 43 and motor 45 is transported to the heater core 47 or the chiller 27.

[0259] With this configuration, after the battery 41 and the motor 45 are warmed up, the heater core 47 or the chiller 27 can be heated by the hot refrigerant. (1i) In the first embodiment, a configuration including a heat storage element connected to the first valve V1 through a flow path can be adopted. Then, for at least one of the flow paths passing through only a single heat storage element among the multiple heat storage elements, the flow path connecting the inverter 43 and the heat storage element (i.e., the heat storage element other than the inverter 43), the flow path connecting the motor 45 and the heat storage element (i.e., the heat storage element other than the motor 45), and the flow paths connecting the inverter 43, the motor 45, and the heat storage element (i.e., the heat storage element other than the inverter 43 and the motor 45), the flow path can be switched by the first valve V1 or the like so that the flow path becomes a closed circuit.

[0260] With this configuration, heat can be stored in the heat storage element in an optimal manner. (1j) In the first embodiment, when the vehicle 1 is stopped or when a system that controls the vehicle 1 (for example, the vehicle system 3) is stopped, the flow path can be made a closed circuit.

[0261] With this configuration, for example, when the outside air temperature is low, it is possible to suppress a decrease in temperature of the components (for example, the battery 41) to which the thermal coolant is supplied. (1k) In the first embodiment, a configuration including a heat storage element connected to the first valve V1 through a flow path can be adopted. When it is determined that the heat storage element has fallen below a predetermined temperature, the inverter 43 and / or the motor 45 performs temperature increase control, and the first valve V1 and / or the second valve V2 or the like can switch the flow path of the heat refrigerant so that the heat refrigerant heated thereby is transported to the heat storage element.

[0262] With this configuration, when the temperature of the heat storage element is low, the temperature of the heat storage element can be increased suitably. (1l) In the first embodiment, when the vehicle 1 is started, the inverter 43 performs temperature rise control, and the flow path can be configured to supply the heat refrigerant that has passed through the inverter 43 to the heater core 47. In addition, the flow path of the heat refrigerant connected to the motor 45 can be a closed circuit, or the flow path of the heat refrigerant connected to the motor 45 can be connected to the battery 41.

[0263] With this configuration, even if the outside air temperature is low when the vehicle is started, heating can be performed appropriately, and a drop in the temperature of the motor 45 or the battery 41 can be suppressed. (1m) In this first embodiment, when the destination of the vehicle 1 is a charger that charges the battery 41, at least one of the inverter 43 and the motor 45 is heated up and at least one of the inverter 43 and the motor 45 that has been heated up can be connected to the battery 41 by a flow path for a thermal refrigerant.

[0264] With this configuration, the battery 41 can be heated in advance to a temperature suitable for charging before charging. (1n) In the first embodiment, when there is a request to warm up the battery 41 while the vehicle 1 is stopped, the inverter 43 performs temperature increase control, and the first valve V1 or the like can be used to switch the flow path of the thermal refrigerant so that the inverter 43 and the battery 41 are connected to each other. Furthermore, when the warm-up of the battery 41 is completed, the flow path connected to the battery 41 can be made a closed circuit.

[0265] With this configuration, when there is a warm-up request, the battery 41 can be warmed up appropriately, and when the warm-up is completed, a drop in the temperature of the battery 41 can be suppressed. [1-8. Correspondence] Next, the relationship between the first embodiment and the present disclosure will be described.

[0266] The vehicle 1 corresponds to a moving body, the vehicle system 3 corresponds to a temperature control device for a moving body, the vehicle control device 9 corresponds to a control unit, the inverter 43 corresponds to an inverter, the motor 45 corresponds to a motor, the piping H corresponds to a piping, and the first valve V1 corresponds to a valve.

[0267] [2. Second embodiment] Since the second embodiment has a basic configuration similar to that of the first embodiment, the following mainly describes the differences from the first embodiment. Note that the same reference numerals as those in the first embodiment indicate the same configuration, and the preceding description is to be referred to.

[0268] In the second embodiment, the differences from the first embodiment will be mainly described. As shown in FIG. 49, in the second embodiment, the temperature control circuit 7 does not use valves that switch the flow path in eight directions like the first and second valves V1, V2 in the first embodiment, but rather uses a single flow path switching valve (hereinafter referred to as the overall valve SV) to achieve the functions of the first and second valves V1, V2.

[0269] This general valve SV has 14 openings so that it can be connected to the flow paths of the 14 pipes H. By adjusting the valve opening of the general valve SV, it is possible to switch the connection state between the flow paths of the 14 pipes H and the 14 openings.

[0270] For example, the chiller 27, motor 45, radiator 49, water-cooled condenser 25, heater core 47, inverter 43, and battery 41 can each be connected to the general valve SV via a pair of pipes H (e.g., pipes H for the inflow and outflow of the heat refrigerant).

[0271] In addition, a pump P is provided in a given pipe H as required. The second embodiment provides the same effects as the first embodiment. [3. Third embodiment] Since the third embodiment has a basic configuration similar to that of the first embodiment, the following description will mainly focus on the differences from the first embodiment. Note that the same reference numerals as those in the first embodiment indicate the same configurations, and the preceding description will be referred to.

[0272] In the third embodiment, differences from the first embodiment will be mainly described. As shown in FIG. 50, in the third embodiment, instead of a valve that switches the flow path in eight directions like the first and second valves V1, V2 in the first embodiment, the functions of the first and second valves V1, V2 are realized by a switching valve (hereinafter referred to as a three-way valve TV) in which the flow path is divided into three directions, and a plurality of electromagnetic on-off valves EV.

[0273] Specifically, a three-way valve TV is disposed in pipe HA of pipe H of the temperature control circuit 7 between the downstream side of the inverter 43 and the upstream side of the motor 45, and the three-way valve TV is connected to another pipe HB so as to communicate with the inverter 43 and the motor 45 and also with a plurality of electromagnetic on-off valves EV.

[0274] Another pipe HB is connected to a radiator 49, a chiller 27, a battery 41, a heater core 47, and a water-cooled condenser 25 via electromagnetic on-off valves EV1 to EV4, respectively. Further, a flow path is configured so that the heat refrigerant flowing out from the radiator 49 is supplied to the inverter 43 and the chiller 27 via electromagnetic opening / closing valves EV5 and EV6, respectively.

[0275] A flow path is configured so that the heat refrigerant flowing out from the chiller 29 is supplied to the inverter 43 and the battery 41 via the electromagnetic on-off valves EV7 and EV8, respectively. A flow path is configured so that the heat refrigerant flowing out from the battery 41 is supplied to the inverter 43 .

[0276] A flow path is configured so that the hot refrigerant flowing out from the heater core 47 is supplied to a radiator 49 via an electromagnetic opening / closing valve EV9. The heat refrigerant flowing out from the motor 45 is supplied to the water-cooled condenser 25, and is also supplied to the radiator 49, the chiller 27, and the battery 41 via the electromagnetic on-off valves EV10 to EV12. The heat refrigerant flowing out from the water-cooled condenser 25 is also supplied to the heater core 47 via the electromagnetic on-off valve EV13.

[0277] The third embodiment provides the same effects as the first embodiment. [4. Other embodiments] Although the embodiments of the present disclosure have been described above, it goes without saying that the present disclosure is not limited to the above-described embodiments and can take various forms.

[0278] (4a) The first valve may be provided either between the piping connecting the heat refrigerant outlet side of the inverter and the heat refrigerant inlet side of the motor, or between the piping connecting the heat refrigerant outlet side of the motor and the heat refrigerant inlet side of the inverter.

[0279] Therefore, in the temperature control circuits of each figure, it is also possible to interchange the positions of the inverter and the motor. In this case, it is desirable to place each heating target according to the characteristics of the inverter and the motor downstream of the flow path to which the heat refrigerant is supplied. For example, in the case of a heating target that requires responsiveness, it is desirable to place the heating target downstream of the inverter, and in the case of a heating target that can be heated using heat storage, it is desirable to place the heating target downstream of the motor. It is also preferable to place the pump upstream or downstream of the motor.

[0280] (4b) Examples of the mobile body include, in addition to vehicles, aircraft, drones (UAV: Unmanned aerial vehicle), etc. Examples of the mobile body include, but are not limited to, mobile bodies that are driven by electricity alone. For example, the mobile body may be equipped with an internal combustion engine in addition to a battery, and may be driven by using the driving force of the internal combustion engine.

[0281] (4c) As for the valves, in addition to the first to third valves, other valves may be disposed in the piping. Moreover, the temperature control circuit may be configured using a first valve and a second valve instead of the first to third valves. In other words, it is also possible to form a temperature control circuit without using the third valve.

[0282] For example, in Operation Examples 3, 5, 20, 27, etc., the first and second valves can form a flow path that heats the battery or motor using heat generated by the inverter. Also, in Operation Examples 17, 20, 27, etc., the first and second valves can form a flow path that heats the water-cooled condenser, heater core, or motor itself using heat generated by the motor.

[0283] Furthermore, in addition to the eight-way switching valve, a valve that can be switched in other directions may be used. When a valve with a fixed flow path (for example, a valve with a fixed three-way flow path) is used, a temperature control circuit may be configured by combining it with an electromagnetic valve that opens and closes the flow path.

[0284] The valves of each embodiment may be appropriately combined to configure a temperature control circuit. (4d) In the present disclosure, the conditions for generating heat include temperature increase control (i.e., heat generation control) in which heat is generated by passing a current through at least one of the inverter and the motor, but other conditions may also be adopted.

[0285] For example, if at least one of the inverter and the motor generates heat through normal operation (i.e., the operation that the equipment is originally intended to perform: the originally set operation) and is in a state in which it is possible to heat the thermal refrigerant (e.g., if it is at or above a predetermined temperature), control may be performed by the transport control unit.

[0286] (4e) The control of the temperature control device for a mobile body and the method thereof described in the present disclosure may be realized by a special purpose computer provided by configuring a processor and memory programmed to perform one or more functions embodied in a computer program.

[0287] Alternatively, the control of the temperature adjustment device for a moving object and the method thereof described in the present disclosure may be realized by a special-purpose computer provided by configuring a processor with one or more dedicated hardware logic circuits.

[0288] Alternatively, the control of the temperature control device for a mobile body and the methods thereof described in the present disclosure may be realized by one or more special-purpose computers configured by a combination of a processor and memory programmed to perform one or more functions and a processor configured by one or more hardware logic circuits.

[0289] The computer program may be stored in a computer-readable non-transitory recording medium as instructions executed by a computer. The method for realizing the functions of each part included in the control of the temperature control device for a mobile body does not necessarily have to include software, and all of the functions may be realized using one or more pieces of hardware.

[0290] (4f) The present disclosure can also be realized in various forms, such as a program for functioning the computer of the above-mentioned temperature control device for a moving body, a non-transient tangible recording medium such as a semiconductor memory on which this program is recorded, and a control method.

[0291] (4g) Multiple functions possessed by one component in each of the above embodiments may be realized by multiple components, or one function possessed by one component may be realized by multiple components.
