[0011] Hereinafter, an embodiment will be described with reference to the drawings.

[0012] [Vehicle hardware configuration] The hardware configuration of a vehicle 1 according to this embodiment will be described with reference to FIG.

[0013] FIG. 1 is a block diagram showing an example of a hardware configuration of a vehicle 1.

[0014] The vehicle 1 is an electric vehicle that can run on the power of a motor generator (MG) 10. The vehicle 1 is, for example, a battery electric vehicle (BEV), a hybrid electric vehicle (HEV), a plug-in hybrid electric vehicle (PHEV), a range extender EV, or the like.

[0015] 1, the vehicle 1 includes an MG 10, a battery 12, and a PCU (Power Control Unit) 14. The vehicle 1 also includes an MG-ECU (Electronic Control Unit) 20, a battery ECU 30, an air conditioner device 40, an air conditioner ECU 50, a sensor 60, an input device 70, a display device 80, and an integrated control ECU 90.

[0016] MG10 (an example of an electric motor) drives the drive wheels of the vehicle 1. Furthermore, MG10 regenerates power using the kinetic energy of the vehicle 1 when braking (decelerating) the vehicle 1. The drive wheels of the vehicle 1 may be the front wheels, the rear wheels, or both the front and rear wheels. Furthermore, the left and right drive wheels may be driven by a single MG 10, or, for example, an MG 10 may be provided for each of the left and right drive wheels, such as in an in-wheel type. MG10 is, for example, a three-phase AC motor generator.

[0017] The battery 12 supplies power to the MG 10 via the PCU 14. The battery 12 has a relatively high output voltage of, for example, several hundred volts. The battery 12 is, for example, a lithium ion battery.

[0018] The battery 12 is disposed in the vehicle cabin of the vehicle 1. The battery 12 is disposed, for example, in a vertical space between the floor and the rear seat in the vehicle cabin of the vehicle 1. The battery 12 may also be disposed on the floor of the luggage compartment of the vehicle 1. The battery 12 is capable of exchanging heat with the air in the vehicle cabin. A blower, a duct, or the like may also be provided to blow the air in the vehicle cabin to the battery 12 to actively exchange heat. As a result, for example, in a situation where the temperature T of the battery 12 (hereinafter, "battery temperature") is relatively high, the battery 12 is cooled by the air in the vehicle cabin that is cooled by the air conditioning device 40 in operation. Therefore, even in a situation where the temperature of the battery 12 rises significantly due to the environmental conditions or driving conditions of the vehicle 1, the temperature of the battery 12 can be maintained at an appropriate temperature at which the input / output characteristics are not restricted by the action of the air conditioning device 40. In addition, for example, in a situation where the battery temperature T is relatively low, the battery 12 is overheated by the air that is warmed by the heating of the air conditioning device 40 in operation. Therefore, even if, for example, the outside air temperature is below freezing and the battery temperature T is very low when the vehicle 1 is started, the temperature of the battery 12 can be quickly raised to a range in which the input / output characteristics are not restricted.

[0019] The PCU 14 drives the MG 10 using the power of the battery 12 under the control of the MG-ECU 20. The PCU 14 includes, for example, an inverter circuit that converts the DC power of the battery 12 into three-phase AC power of a predetermined voltage and a predetermined frequency and outputs it to the MG 10, or converts the regenerative power of the MG 10 into DC power and outputs it to the battery 12. The PCU 14 may also include a step-up / step-down converter that boosts the voltage of the battery 12 and outputs it to the inverter circuit, or that reduces the regenerative power (DC) of the MG 10 output from the inverter circuit and outputs it.

[0020] The MG-ECU 20 performs drive control of the MG 10 through the PCU 14 under the control of the integrated control ECU 90. The MG-ECU 20 is communicatively connected to the integrated control ECU 90 through an in-vehicle network such as a Controller Area Network (CAN) or an in-vehicle Ethernet.

[0021] For example, the MG-ECU 20 outputs a control signal to the PCU 14, thereby causing the PCU 14 to drive the MG 10 so as to realize a desired running state of the vehicle 1.

[0022] The battery ECU 30 (an example of a first acquisition unit) performs control related to the battery 12 under the control of the integrated control ECU 90. The battery ECU 30 is communicatively connected to the integrated control ECU 90 via an in-vehicle network such as a CAN or an in-vehicle Ethernet.

[0023] For example, the battery ECU 30 acquires detection data from sensors built into the battery 12 that detect various states of the battery 12, and monitors the state of the battery 12. The states of the battery 12 include, for example, the charge amount (SOC: State Of Charge) of the battery 12, the deterioration state of the battery 12, the voltage balance state of each unit cell of the battery 12, and the like. The sensors built into the battery 12 include, for example, a voltage sensor that detects the voltage of the battery 12, a current sensor that detects the current of the battery 12, a temperature sensor that detects the battery temperature T, and the like. For example, the monitoring results of the battery 12 by the battery ECU 30 and the detection data of the various sensors built into the battery 12 that are used for the monitoring are taken into the integrated control ECU 90 via an in-vehicle network.

[0024] The air conditioner device 40 (an example of an air conditioner) adjusts the temperature, humidity, etc., of the vehicle interior that accommodates passengers and luggage of the vehicle 1 under the control of the air conditioner ECU 50. The air conditioner device 40 is communicatively connected to the air conditioner ECU 50, for example, via a one-to-one communication line.

[0025] The air conditioner 40 includes, for example, a heat pump cycle including an evaporator, a compressor, a condenser, a receiver, an expansion valve, etc., a blower for blowing air, a duct including an air outlet into the vehicle interior, and various sensors. The various sensors include, for example, a sunshine sensor, an outside air temperature sensor, a temperature sensor inside the vehicle interior (air outlet), a humidity sensor, etc. Detection data of the various sensors mounted in the air conditioner 40 is input to the air conditioner ECU 50.

[0026] The air conditioner ECU 50 (an example of a second acquisition unit) controls the operation of the air conditioner device 40 based on detection data from various sensors mounted in the air conditioner device 40.

[0027] For example, the air conditioner ECU 50 controls the operation of the heat pump cycle, blower, etc. of the air conditioner device 40 based on detection data from various sensors mounted on the air conditioner device 40 so that the temperature inside the vehicle compartment becomes a target temperature.

[0028] The air conditioner ECU 50 is communicably connected to the integrated control ECU 90 via an in-vehicle network, and detection data from various sensors mounted on the air conditioner device 40 is acquired by the air conditioner ECU 50 and is then input to the integrated control ECU 90.

[0029] The sensor 60 (an example of a third acquisition unit) acquires detection data related to the traveling state of the vehicle 1. The sensor 60 includes, for example, a wheel speed sensor that acquires detection data related to the speed of wheels such as driving wheels and driven wheels of the vehicle 1, an acceleration sensor that detects the acceleration of the vehicle 1, an angular velocity sensor that detects the angular velocity of the vehicle 1, and the like. The sensor 60 also includes, for example, a GNSS (Global Navigation Satellite System) sensor that detects position information of the vehicle 1.

[0030] The sensor 60 is communicatively connected to the integrated control ECU 90 via, for example, a one-to-one communication line or an in-vehicle network, and the detection data of the sensor 60 is input to the integrated control ECU 90.

[0031] The input device 70 is provided in the cabin of the vehicle 1 and receives input from occupants of the vehicle 1, such as the driver and passengers.

[0032] The input device 70 includes, for example, a mechanical input device that accepts a mechanical input from an occupant. The mechanical input device includes, for example, a button, a toggle, a lever, a touch panel, a touch pad, and the like.

[0033] The input device 70 may also include a voice input device that accepts voice input from the occupant, a gesture input device that accepts gesture input, or a biometric input device that accepts biometric input.

[0034] The display device 80 (an example of an alarm device) is provided in the cabin of the vehicle 1 and displays various information to the occupants of the vehicle 1. The display device 80 is, for example, a liquid crystal display or an organic EL (Electroluminescence) display. The display device 80 may include multiple display devices depending on the application. For example, the display device 80 includes a meter display provided in front of the driver's seat on the instrument panel, and a center display located in the center of the instrument panel.

[0035] The integrated control ECU 90 (an example of a control device) cooperates with various ECUs of the vehicle 1, such as the MG-ECU 20, the battery ECU 30, and the air conditioner ECU 50, and performs integrated control of the vehicle 1 as a higher-level device of the various ECUs.

[0036] For example, the integrated control ECU 90 controls the vehicle 1 in response to the operation state of the accelerator, brake, etc. by the driver of the vehicle 1 and various states of the battery 12 monitored by the battery ECU 30. The control command is output to the MG-ECU 20 so as to realize the desired driving state.

[0037] The functions of the integrated control ECU 90 are realized by any hardware or any combination of hardware and software, etc. For example, as shown in Fig. 1, the integrated control ECU 90 includes an auxiliary storage device 90A, a memory device 90B, a CPU 90C, and an interface device 90D.

[0038] The auxiliary storage device 90A is a non-volatile storage means, and stores the programs to be installed as well as necessary files, data, etc. The auxiliary storage device 90A is, for example, a flash memory.

[0039] For example, when an instruction to start a program is received, the memory device 90B loads the program from the auxiliary storage device 90A so that the program can be read by the CPU 90C. The memory device 90B is, for example, a static random access memory (SRAM).

[0040] The CPU 90C executes, for example, a program loaded into the memory device 90B, and realizes various functions of the integrated control ECU 90 according to instructions of the program.

[0041] The interface device 90D is used, for example, as an interface for connecting to a communication line inside the vehicle 1. The interface device 90D may include a plurality of different types of interface devices in accordance with the types of communication lines to be connected.

[0042] The programs for realizing various functions of the integrated control ECU 90 are provided by, for example, a portable recording medium 90E. In this case, the interface device 90D functions as an interface for reading data from the recording medium 90E and writing data to the recording medium 90E. The recording medium 90E is a dedicated tool connected to an external connection connector such as a DLC (Data Link Coupler) by a detachable cable. The recording medium 90E may also be, for example, an SD memory card or a USB (Universal Serial Bus) memory. The programs may also be downloaded from a computer outside the vehicle 1 through a predetermined communication line and installed in the auxiliary storage device 90A.

[0043] [Vehicle Functional Configuration] Next, the functional configuration of the vehicle 1 (the integrated control ECU 90) will be described with reference to FIGS.

[0044] FIG. 2 is a functional block diagram showing an example of the functional configuration of the vehicle 1 (integrated control ECU 90). FIG. 3 is a diagram showing an example of the input / output characteristics of the battery 12. Specifically, in FIG. 3, the output characteristics of the battery 12 are shown above the horizontal axis, and the input characteristics of the battery 12 are shown below the horizontal axis. FIG. 4 is a diagram showing an example of a calculation method of the running power Y in the current state of the battery 12. Specifically, FIG. 4 is an example of data (graph) showing the relationship between the battery temperature T and the running power Y when the vehicle 1 can run using energy other than the power of the battery 12, such as an HEV, a PHEV, or a range extender EV. FIG. 4 shows a range in which the battery temperature T is higher than a predetermined value T1 described later.

[0045] The integrated control ECU 90 includes a calculation unit 901 , a condition determination unit 902 , and a notification unit 903 .

[0046] The calculation unit 901 calculates the running power X, the running power Y, and the power consumption Z when the air conditioner device 40 that is not in operation is operated.

[0047] The running power X (an example of a second power) represents a power rate (energy consumption rate) that the vehicle 1 needs to output in order to run the vehicle 1 when there are no input / output restrictions on the battery 12.

[0048] The running power Y (an example of a first power) represents a power rate (energy consumption rate) that needs to be output by the vehicle 1 in order to run the vehicle 1 in the current state of the battery 12.

[0049] For example, as shown in Fig. 3, when the battery temperature T is in an appropriate temperature range (hereinafter referred to as "unrestricted range") between a predetermined value T1 and a predetermined value T2 (>T1) each, the output power and the input power of the battery 12 are constant maximum values. The state in which there is no input / output restriction on the battery 12 corresponds to the case in which the battery temperature T is in the unrestricted range.

[0050] On the other hand, when the battery temperature T is outside the non-restricted range, the output power and input power of the battery 12 are restricted to be lower than the maximum values. Specifically, when the battery temperature T is in a range lower than a predetermined value T1 (hereinafter, "low temperature restricted range"), the output power and input power of the battery 12 decrease in a downwardly convex curve as the battery temperature T decreases. Also, when the battery temperature T is in a range higher than a predetermined value T2 (hereinafter, "high temperature restricted range"), the output power and input power of the battery 12 decrease linearly as the battery temperature T increases.

[0051] In a state where there is no input / output limit on the battery 12, the input power of the battery 12 is relatively large, and therefore the amount of electric power stored in the battery 12 during deceleration of the vehicle 1 is relatively large. Therefore, in a state where there is no input / output limit on the battery 12, the actual power taken out from the battery 12 is suppressed, and the power output that the vehicle 1 needs to output to run the vehicle 1, i.e., the running power X, becomes relatively small. Also, for example, if the vehicle 1 is an HEV or a PHEV, in a state where there is no input / output limit on the battery 12, the output power of the battery 12 is relatively large, and therefore the output of the engine when achieving a desired running state is suppressed. Therefore, in a state where there is no input / output limit on the battery 12, the amount of fuel consumption is suppressed, and the power output that the vehicle 1 needs to output to run the vehicle 1 (i.e., the running power X) becomes relatively small.

[0052] On the other hand, in a state where the input / output of the battery 12 is limited, the input power of the battery 12 is relatively small, and therefore the amount of power stored in the battery 12 during deceleration of the vehicle 1 is relatively small. Therefore, in a state where the input / output of the battery 12 is limited, the actual amount of power taken out from the battery 12 increases, and the power output that the vehicle 1 needs to output in order to run the vehicle 1 becomes relatively large. Also, for example, if the vehicle 1 is an HEV or a PHEV, in a state where the input / output of the battery 12 is limited, the output power of the battery 12 is relatively small, and therefore the output of the engine increases when achieving a desired running state. Therefore, in a state where the input / output of the battery 12 is limited, the amount of fuel consumed increases, and the power output that the vehicle 1 needs to output in order to run the vehicle 1 becomes relatively large.

[0053] Therefore, when the current state of battery 12 is a state without input / output restrictions, running power Y is equal to running power X, and when the current state of battery 12 is a state with input / output restrictions, running power Y is greater than running power X.

[0054] The running power X is, for example, a power that the vehicle 1 needs to output in order to run the vehicle 1 in an assumed average running state in a state where there is no input / output restriction of the battery 12. In this case, the running power Y is similarly a power that the vehicle 1 needs to output in order to run the vehicle 1 in an assumed average running state in the current temperature state of the battery 12. For example, the running power X is calculated as a value obtained by dividing the energy consumption when the vehicle 1 is run in a predetermined running mode corresponding to the average running state of the vehicle 1 in a state where there is no input / output restriction of the battery 12 by the required time of the running mode. The energy consumption when the vehicle 1 is run in the predetermined running mode is, for example, specified in advance through experiments, simulations, etc. during the development of the vehicle 1. The predetermined running mode corresponding to the average running state is, for example, an urban mode assuming running in an urban area in the Worldwide-harmonized Light vehicles Test Cycle (WLTC). In addition, the predetermined driving mode corresponding to the average driving state may be selected from a plurality of modes such as an urban mode, a suburban mode assuming driving in the suburbs, a highway mode assuming driving on a highway, and a WLTC mode, depending on the history of the past driving states of the vehicle 1. The history of the past driving states of the vehicle 1 is acquired based on detection data of the sensor 60, for example.

[0055] The running power X may be a power that the vehicle 1 needs to output in order to run the vehicle 1 in the current running state without input / output restrictions on the battery 12. In this case, the running power Y is similarly a power that the vehicle 1 needs to output in order to run the vehicle 1 in the current running state under the current temperature condition of the battery 12. For example, the running power X is calculated as a value obtained by dividing the energy consumption when the vehicle 1 is run in a predetermined running mode corresponding to the current running state of the vehicle 1 without input / output restrictions on the battery 12 by the required time for that running mode. The predetermined running mode corresponding to the current running state of the vehicle 1 is selected from a plurality of running modes depending on, for example, the current vehicle speed of the vehicle 1 and the type of road on which the vehicle 1 is running. The current vehicle speed of the vehicle 1 and the type of road on which the vehicle 1 is running can be determined from the detection data of the sensor 60. The plurality of running modes include, for example, an urban mode, a suburban mode, and a highway mode.

[0056] The running power Y is calculated based on data that defines the relationship between the battery temperature T and the running power Y, for example.

[0057] 4, when the battery temperature T is in an unlimited range between a predetermined value T1 and a predetermined value T2, the running power Y has a constant minimum value Ymin. The minimum value Ymin is equal to the running power X.

[0058] In the high temperature limit range where the battery temperature T is greater than a predetermined value T2 and less than or equal to a predetermined value T3, the running power Y increases linearly as the battery temperature T increases, because the input power and output power of the battery 12 decrease linearly (see FIG. 3).

[0059] When the battery temperature T is in a range equal to or higher than a predetermined value T3, the input and output of electric power to and from the battery 12 becomes zero (see FIG. 3), and therefore the running power Y takes a constant maximum value Ymax.

[0060] The maximum value Ymax is calculated, as in the case of the running power X, by dividing the amount of energy consumed when the vehicle 1 is run in a predetermined running mode of the vehicle 1 with zero input / output from the battery 12, by the time required for that running mode.

[0061] The data defining the relationship between the battery temperature T and the running power Y is, for example, predefined according to a predetermined running mode corresponding to an average running state of the vehicle 1. Furthermore, as described above, the data defining the relationship between the battery temperature T and the running power Y may be defined for each of a plurality of running modes when a predetermined running mode corresponding to the current running state of the vehicle 1 is selected from a plurality of running modes.

[0062] In addition, if the vehicle 1 is a BEV, when the temperature of the battery 12 becomes equal to or higher than a predetermined value T3, power cannot be supplied from the battery 12, and therefore the vehicle 1 cannot run. Also, for a low temperature restricted range in which the battery temperature T is lower than a predetermined value T1, the relationship between the battery temperature T and the running power Y may be specified. In this case, the running power Y may be specified in such a manner that as the battery temperature T decreases, the input power and output power of the battery 12 decrease in a downwardly convex curve (see FIG. 3), and thus the running power Y increases in an upwardly convex curve.

[0063] The power consumption Z when the inactive air conditioning device 40 is activated is calculated based on, for example, the current temperature inside the vehicle cabin and a target temperature inside the vehicle cabin. The target temperature inside the vehicle cabin is, for example, the most recently set or default set temperature of the air conditioning device 40. The target temperature inside the vehicle cabin may also be set based on the current battery temperature T as a temperature required to cool the battery 12 using a predetermined calculation formula, map, or the like.

[0064] The condition determination unit 902 determines whether or not a condition for issuing a notification to prompt the operation of the air conditioner device 40 that is not in operation is satisfied.

[0065] The notification unit 903 issues a notification via the display device 80 to prompt the operation of the air conditioner device 40 that is not in operation.

[0066] [Integrated control ECU control processing] Next, the control process of the integrated control ECU 90 will be described with reference to FIG.

[0067] FIG. 5 is a flowchart illustrating an example of a control process of the integrated control ECU 90. As shown in FIG.

[0068] This flowchart is executed, for example, when the battery temperature T is in the non-restricted range or the high temperature restricted range and the air conditioner device 40 is not operating (OFF). This flowchart may also be executed when the battery temperature T is in the high temperature restricted range and the air conditioner device 40 is not operating (OFF).

[0069] In step S102, the condition determination unit 902 determines whether the difference between the running power Y and the running power X is greater than the power consumption Z when the non-operating air conditioner device 40 is operated, based on the latest output of the calculation unit 901. If the condition is met, the condition determination unit 902 determines that the fuel consumption rate (fuel economy) or the power consumption rate (electricity consumption) of the vehicle 1 will be improved by operating the non-operating air conditioner device 40, and proceeds to step S104. This is because the improvement in fuel economy or electricity consumption of the vehicle 1 due to the operation of the air conditioner device 40 (the difference between the running power Y and the running power X) is greater than the deterioration in fuel economy or electricity consumption of the vehicle 1 due to the operation of the air conditioner device 40 (power consumption Z). On the other hand, if the condition is not met, the condition determination unit 902 determines that the fuel economy or electricity consumption of the vehicle 1 will not be improved even if the non-operating air conditioner device 40 is operated, and ends the processing of this flowchart.

[0070] In step S104, the notification unit 903 causes the display device 80 to display a notification (an example of a first notification) proposing (urging) the occupants of the vehicle 1 to operate the non-operating air conditioner device 40 (cooling). At this time, the notification unit 903 may cause the display device 80 to display an indication that the fuel economy or electricity efficiency of the vehicle 1 will be improved by operating the non-operating air conditioner device 40.

[0071] When the process of step S104 is completed, the integrated control ECU 90 proceeds to step S106.

[0072] In step S106, the condition determination unit 902 determines whether or not an operation to operate (ON) the air conditioning unit 40 from an occupant of the vehicle 1 has been accepted through the input device 70. If an operation to operate (ON) the air conditioning unit 40 has been accepted through the input device 70, the condition determination unit 902 proceeds to step S116, and otherwise proceeds to step S108.

[0073] In step S108, the condition determination unit 902 determines whether or not a certain time has elapsed since the start of display in step S104. If the condition is met, the condition determination unit 902 proceeds to step S112, and otherwise proceeds to step S110.

[0074] In step S110, the condition determination unit 902 determines whether or not the difference between the running power Y and the running power X is smaller than the power consumption Z when the non-operating air conditioner device 40 is operated, based on the latest output of the calculation unit 901. If the condition is met, the condition determination unit 902 determines that a situation has arisen in which the fuel consumption rate (fuel economy) or the power consumption rate (electricity efficiency) of the vehicle 1 will not improve even if the non-operating air conditioner device 40 is operated, and proceeds to step S116. On the other hand, if the condition is not met, the condition determination unit 902 determines that a situation in which the fuel consumption rate (fuel economy) or the power consumption rate (electricity efficiency) of the vehicle 1 will improve by operating the non-operating air conditioner device 40 continues, and returns to step S106.

[0075] Meanwhile, in step S112, the notification unit 903 switches the display device 80 from a state in which a notification is displayed suggesting to the occupants of the vehicle 1 to operate the non-operating air conditioner device 40 to a state in which a notification (an example of a second notification) indicating that the battery temperature T is relatively high is displayed. This changes the manner of the notification, thereby making it possible to further encourage the user to pay attention to the notification. It is also possible to reduce the annoyance felt by the occupants of the vehicle 1 due to the continuous suggestion to operate the air conditioner device 40 and the discomfort felt by the continuous display of the same notification.

[0076] The notification indicating that the battery temperature T is relatively high may be displayed in the same location as the notification suggesting to the occupants of the vehicle 1 to operate the non-operating air conditioning device 40, or may be displayed in a different location. In the latter case, for example, the notification indicating that the battery temperature T is relatively high is displayed in a location different from the location where the notification suggesting to the occupants of the vehicle 1 to operate the non-operating air conditioning device 40 is displayed on the same display device 80. Furthermore, the notification indicating that the battery temperature T is relatively high may be displayed on a display device 80 other than the display device 80 on which the notification suggesting to the occupants of the vehicle 1 to operate the non-operating air conditioning device 40 is displayed.

[0077] When the process of step S112 is completed, the integrated control ECU 90 proceeds to step S114.

[0078] In step S114, the condition determination unit 902 determines whether the difference between the running power Y and the running power X is smaller than the power consumption Z when the non-operating air conditioner device 40 is operated, based on the latest output of the calculation unit 901. If the condition is met, the condition determination unit 902 determines that a situation has arisen in which the fuel consumption rate (fuel economy) or the power consumption rate (electricity efficiency) of the vehicle 1 will not improve even if the non-operating air conditioner device 40 is operated, and proceeds to step S116. On the other hand, if the condition is not met, the condition determination unit 902 determines that a situation in which the fuel consumption rate (fuel economy) or the power consumption rate (electricity efficiency) of the vehicle 1 will improve by operating the non-operating air conditioner device 40 continues, and repeats the processing of this step.

[0079] In step S116, the notification unit 903 terminates the display of step S104 on the display device 80 (a notification suggesting to the occupants of the vehicle 1 to operate the non-operating air conditioning device 40) or the display of step S112 (a notification indicating that the battery temperature T is relatively high).

[0080] When the process of step S116 is completed, the process of this flowchart ends.

[0081] Incidentally, after the notification in step S104, when an operation to operate the air conditioner device 40 is performed and this flowchart is ended, processing of another flowchart may be started, and a determination process similar to steps S110 and S114 may be repeatedly performed at a predetermined processing cycle. Then, when the conditions of the determination process are established, the integrated control ECU 90 may notify the occupant via the display device 80 that the air conditioner device 40 may be deactivated. This is because it can be determined that a situation has arisen in which the fuel consumption rate (fuel economy) and power consumption rate (electricity efficiency) of the vehicle 1 will not improve even if the air conditioner device 40 is continued to operate.

[0082] In this manner, in this example, when the battery temperature T is relatively high and the difference between the running power X and the running power Y is greater than the power consumption Z when the air conditioner device 40 is operated, the integrated control ECU 90 issues a notification to prompt the operation of the air conditioner device 40 (cooling).

[0083] As a result, the integrated control ECU 90 can operate the air conditioning device 40 at the will of the occupant of the vehicle 1, thereby improving the fuel consumption rate (fuel economy) and the power consumption rate (electricity efficiency) of the vehicle 1. In addition, the integrated control ECU 90 can suppress a situation in which the air conditioning device 40 is automatically operated, causing discomfort to the occupant of the vehicle 1, for example.

[0084] [Other embodiments] Next, another embodiment will be described.

[0085] The above-described embodiment may be modified or altered as appropriate.

[0086] For example, in the above embodiment, when the battery temperature T is relatively low and the difference between the running power X and the running power Y is larger than the power consumption Z when the air conditioner device 40 is operated, a notification may be made to encourage the operation of the air conditioner device 40 (heating). In this case, the flowchart of FIG. 5 may be performed without limiting the range of the battery temperature T on the premise that the air conditioner device 40 is not operated, or may be performed when the battery temperature T is in the high temperature limit range or the low temperature limit range. In addition, in step S104 of the flowchart of FIG. 5, a suggestion to operate the air conditioner device 40 in the cooling mode and a suggestion to operate the air conditioner device 40 in the heating mode may be switched depending on whether the battery temperature T is in the high temperature limit range or the low temperature limit range. In addition, in step S112 of the flowchart of FIG. 5, a display to notify that the battery temperature T is high and a display to notify that the battery temperature T is low may be switched depending on whether the battery temperature T is in the high temperature limit range or the low temperature limit range.

[0087] In the above-described embodiment and its modified example, a notification may be issued to encourage the user to increase the output of the air conditioner device 40 in operation in order to improve the fuel consumption rate (fuel economy) or the power consumption rate (electricity efficiency) of the vehicle 1. Increasing the output of the air conditioner device 40 in operation includes changing the set temperature (target temperature) in a direction to increase the output and increasing the air volume of the air conditioner device 40. Specifically, a notification may be issued to encourage the user to increase the output of the air conditioner device 40 when the difference between the running power X and the running power Y is greater than the power consumption when the output of the air conditioner device 40 is increased by an amount necessary to bring the battery temperature T into the non-restricted range. In this case, in step S102 of the flowchart in FIG. 5, it may be determined whether or not the difference between the running power X and the running power Y is greater than the power consumption when the output of the air conditioner device 40 is increased by an amount necessary to bring the battery temperature T into the non-restricted range. Similarly, in steps S110 and S114 of the flowchart in FIG. 5, it may be determined whether or not the difference between the running power X and the running power Y is greater than the power consumption when the output of the air conditioner device 40 is increased by an amount necessary to bring the battery temperature T into the non-restricted range. 5, a notification suggesting a predetermined operation for increasing the output of the air conditioning device 40 may be displayed on the display device 80. Furthermore, in step S106 of the flowchart in FIG. 5, it may be determined whether or not a predetermined operation for increasing the output of the air conditioning device 40 has been performed.

[0088] In addition, in the above-described embodiment and its modified examples, it may be determined whether or not the fuel consumption rate (fuel consumption) and the power consumption rate (electricity consumption) of the vehicle 1 are improved by heat exchange with the air in the vehicle cabin by operating the inactive air conditioner 40, taking into consideration various states of the vehicle 1 in a comprehensive manner. Similarly, in the above-described embodiment and its modified examples, it may be determined whether or not the fuel consumption rate (fuel consumption) and the power consumption rate (electricity consumption) of the vehicle 1 are improved by heat exchange with the air in the vehicle cabin by increasing the output of the active air conditioner 40, taking into consideration various states of the vehicle 1 in a comprehensive manner. The various states of the vehicle 1 include, for example, the battery temperature T, the running state of the vehicle 1, the temperature state in the vehicle cabin, and the like. For example, a trained model is prepared that outputs whether or not the fuel consumption rate (fuel consumption) and the power consumption rate (electricity consumption) of the vehicle 1 are improved by operating the inactive air conditioner 40, using data on various states of the vehicle 1 as input conditions. Similarly, for example, a trained model is prepared that uses data on various states of the vehicle 1 as input conditions and outputs whether or not the fuel consumption rate (fuel economy) and the power consumption rate (electricity efficiency) of the vehicle 1 are improved by increasing the output of the air conditioning device 40 in operation. The trained model is generated, for example, by performing reinforcement learning using a virtual simulation based on a virtual vehicle model corresponding to the vehicle 1, and is installed in the integrated control ECU 90 when the vehicle 1 is shipped from a factory or when maintenance is performed at a dealer or the like. The trained model may also be downloaded to the integrated control ECU 90 of the vehicle 1 from an external device such as a server device that is communicatively connected to the vehicle 1.

[0089] In addition, in the above-described embodiments and their variations, the notification unit 903 may notify the occupants of the vehicle 1 by an auditory method using a sound output device (e.g., a speaker, etc.) instead of or in addition to the visual method using the display device 80.

[0090] In the above-described embodiment and its modified examples, some or all of the functions of the calculation unit 901, the condition determination unit 902, and the notification unit 903 may be transferred to another ECU (for example, the air conditioner ECU 50).

[0091] [Effect] Next, the operation of the vehicle 1 (the integrated control ECU 90) according to this embodiment will be described.

[0092] In this embodiment, the vehicle 1 includes an MG 10, an air conditioning device 40, a battery 12, and an alarm device (e.g., a display device 80). Specifically, the MG 10 drives the drive wheels of the vehicle 1. The air conditioning device 40 adjusts the temperature of the air in the vehicle cabin. The battery 12 supplies power to the MG 10 and is configured to be able to exchange heat with the air in the vehicle cabin. The alarm device issues a first alarm to urge an occupant of the vehicle 1 to operate the inactive air conditioning device 40 or to increase the output of the active air conditioning device 40 when the fuel consumption rate or the power consumption rate of the vehicle 1 is improved by heat exchange by operating the inactive air conditioning device 40 or by increasing the output of the active air conditioning device 40.

[0093] This allows the vehicle 1 to prompt the occupant to operate the air conditioner 40 so that the battery temperature T becomes appropriate from the viewpoint of the fuel consumption rate (fuel economy) or the power consumption rate (electricity efficiency) of the vehicle 1 through heat exchange between the battery 12 and the air in the vehicle cabin. This makes it possible to prevent a situation in which the occupant of the vehicle 1 feels uncomfortable, such as when a non-operating air conditioner 40 is automatically operated or the output of an operating air conditioner 40 is automatically increased. This makes it possible to improve the fuel consumption rate (fuel economy) or the power consumption rate (electricity efficiency) of the vehicle 1 while preventing the occupant of the vehicle from feeling uncomfortable.

[0094] In addition, in this embodiment, the vehicle 1 may include a first acquisition unit (e.g., the battery ECU 30) and a control unit (e.g., the integrated control ECU 90). Specifically, the first acquisition unit may acquire data related to the temperature state of the battery 12. Then, based on the data acquired by the first acquisition unit, the control unit may determine whether or not the fuel consumption rate or the power consumption rate of the vehicle 1 will be improved through heat exchange by operating the inactive air conditioning device 40 or by increasing the output of the active air conditioning device 40.

[0095] This allows the vehicle 1 to appropriately determine when the fuel consumption rate (fuel economy) or the power consumption rate (electricity efficiency) of the vehicle 1 will be improved by heat exchange, depending on the temperature state of the battery 12. Therefore, the vehicle 1 can appropriately issue a notification to urge the occupants of the vehicle 1 to operate the air conditioning device 40 that is not in operation, or to increase the output of the air conditioning device 40 that is in operation.

[0096] Furthermore, in this embodiment, the control device may determine that the fuel consumption rate or the power consumption rate of the vehicle 1 will be improved by heat exchange by operating the inactive air conditioning device 40 when the difference between the running power Y required for the vehicle 1 to run in the current temperature state of the battery 12 and the running power X required for the vehicle 1 to run in a temperature state in which the battery 12 has no input / output restrictions is greater than the power consumption Z of the air conditioning device 40 when the inactive air conditioning device 40 is operated. Furthermore, the control device may determine that the fuel consumption rate or the power consumption rate of the vehicle 1 will be improved by heat exchange by increasing the output of the active air conditioning device 40 when the difference between the running power Y and the running power X is greater than the power consumption of the air conditioning device 40 when the output of the active air conditioning device 40 is increased.

[0097] This allows the vehicle 1 (control device) to appropriately determine a case in which the fuel consumption rate (fuel economy) or the power consumption rate (electricity efficiency) of the vehicle 1 is improved by heat exchange.

[0098] In addition, in this embodiment, the vehicle 1 may include a third acquisition unit (for example, an air conditioner ECU 50). Specifically, the third acquisition unit may acquire data related to the temperature inside the vehicle cabin. Then, based on the data related to the temperature inside the vehicle cabin and a target temperature inside the vehicle cabin, the control device may calculate the power consumption of the air conditioner device 40 when a non-operating air conditioner device 40 is operated or when the output of the operating air conditioner device 40 is increased.

[0099] This allows the control device to properly calculate the power consumption of the air conditioning device 40 when a non-operating air conditioning device 40 is operated or when the output of an operating air conditioning device 40 is increased. Therefore, the vehicle 1 (control device) can properly determine the cases where the fuel consumption rate (fuel economy) or the power consumption rate (electricity efficiency) of the vehicle 1 is improved by heat exchange.

[0100] In the present embodiment, the control device may calculate the running power Y and the running power X in accordance with the average running state of the vehicle 1.

[0101] This allows the vehicle 1 (control device) to uniquely calculate the running power Y and the running power X in accordance with the average running state of the vehicle 1. Therefore, the vehicle 1 can reduce the processing load of the control device.

[0102] In the present embodiment, the control device may calculate the running power Y and the running power X in accordance with the current running state of the vehicle 1.

[0103] This allows the vehicle 1 (control device) to vary the running power Y and the running power X in accordance with the current running state of the vehicle 1. Therefore, the vehicle 1 (control device) can more appropriately determine a case where the fuel consumption rate (fuel economy) or the power consumption rate (electricity efficiency) of the vehicle 1 is improved by heat exchange.

[0104] In addition, in this embodiment, the alarm device may issue a first alarm when the fuel consumption rate or power consumption rate of the vehicle 1 can be improved through heat exchange by operating a non-operating air conditioning unit 40 or by increasing the output of an operating air conditioning unit 40, and after a predetermined time has elapsed, may issue a second alarm different from the first alarm to urge the occupants of the vehicle 1 to operate a non-operating air conditioning unit 40 or to increase the output of the operating air conditioning unit 40.

[0105] Thereby, the vehicle 1 can, for example, change the mode of the notification to better encourage the occupants of the vehicle 1 to pay attention to the notification. Also, the vehicle 1 can, for example, reduce the annoyance felt by the occupants of the vehicle 1 and reduce the discomfort felt by the same notification content being repeated by changing the mode of the notification.

[0106] In addition, in the present embodiment, the notification device may be the display device 80. The second notification may be displayed at a location on the display device 80 different from the location on the display device 80 on which the first notification is displayed. The second notification may be displayed on a display device 80 different from the display device 80 on which the first notification is displayed.

[0107] In this way, by changing the display location of the notification, the vehicle 1 can reduce the annoyance felt by the occupants of the vehicle 1 and the discomfort felt by the same notification content being displayed repeatedly.

[0108] In addition, in this embodiment, if, after starting the first alarm, a situation occurs in which operating a non-operating air conditioning unit 40 or increasing the output of an operating air conditioning unit 40 does not improve the fuel consumption rate or power consumption rate of vehicle 1 through heat exchange with the air in the passenger compartment, the alarm device may stop the alarm urging the occupants of vehicle 1 to operate a non-operating air conditioning unit 40 or increase the output of the operating air conditioning unit 40.

[0109] This allows the vehicle 1 to notify the occupants of the vehicle 1 that it is no longer necessary to operate the air conditioning device 40 or to increase the output of the air conditioning device 40.

[0110] In addition, in this embodiment, if, after the start of the first alarm, an occupant of vehicle 1 operates to activate a non-operating air conditioning unit 40 or increases the output of an operating air conditioning unit 40, and thereafter, a situation occurs in which the vehicle's fuel consumption rate or power consumption rate is not improved by heat exchange, the alarm device may alert the occupant of vehicle 1 that the air conditioning unit 40 may be deactivated or the output of the air conditioning unit 40 may be reduced.

[0111] This allows the vehicle 1 to notify the occupants of the vehicle 1 that it is no longer necessary to continue operating the air conditioning device 40 or to keep the air conditioning device 40 at an increased output.

[0112] Although the embodiments have been described in detail above, the present disclosure is not limited to such specific embodiments, and various modifications and improvements are possible within the scope of the gist described in the claims. [Explanation of symbols]
