[0009] In recent years, users have been increasingly using smartphones and other devices to control the air conditioning and door locks of parked vehicles. Services for remotely controlling in-vehicle devices such as actuators (hereinafter sometimes referred to as "remote services") are becoming increasingly common. Vehicles that use remote services are equipped with communication terminals for transmitting and receiving signals related to remote operation. However, if the communication terminal continues to wait in a standby state (a state in which signals related to remote operation can be transmitted and received) while the vehicle is in a stopped state (the ignition switch or power switch is off), the remaining charge of the battery for the communication terminal may become too low or the battery may deteriorate.

[0010] To cope with this, a countermeasure can be considered in which the communication terminal is automatically switched from a standby state to a stopped state (a state in which signals related to remote operation cannot be sent or received) when a certain period (for example, several days) has passed since the vehicle stopped operating (when the power switch or ignition switch was switched from on to off). Meanwhile, in vehicles such as BEVs (Battery Electric Vehicles) and PHEVs (Plug-in Hybrid Electric Vehicles), In vehicles equipped with a drive battery in addition to the battery, when the remaining charge of the communication terminal battery becomes low, the auxiliary battery can be charged using the power of the drive battery. Therefore, in BEVs, PHEVs, etc., a means is required to flexibly switch the state of the communication device, taking into account not only the remaining charge of the auxiliary battery but also the remaining charge of the drive battery.

[0011] Therefore, in the information processing device according to the present disclosure, the control unit acquires a first battery remaining capacity, which is the remaining capacity of the first battery. The first battery is a secondary battery mounted on the vehicle and supplies power to the communication terminal. The first battery may be a battery dedicated to the communication terminal, or may be an auxiliary battery shared by the communication terminal and the vehicle auxiliary. The communication terminal is a terminal mounted on the vehicle and performs communication related to remote operation of the vehicle with a device outside the vehicle. The first battery remaining capacity may be the SOC (State Of Charge) of the first battery.

[0012] In the information processing device according to the present disclosure, the control unit acquires a second battery remaining capacity, which is the remaining capacity of the second battery. The second battery is a secondary battery that supplies power to a drive motor of the vehicle. The drive motor is an electric motor that drives the drive wheels of the vehicle. The second battery remaining capacity may be the SOC of the second battery.

[0013] In addition, the acquisition of the first battery remaining capacity, the acquisition of the second battery remaining capacity, and the switching of the state of the communication terminal may be performed repeatedly at a predetermined period (e.g., several hundred milliseconds to several minutes) when the vehicle is in a stopped state (the power switch or ignition switch is off).

[0014] A control unit of an information processing device according to the present disclosure switches the communication terminal between a standby state and a stopped state according to the acquired first battery remaining amount and second battery remaining amount. For example, when the first battery remaining amount is equal to or greater than a first threshold, the control unit may control the communication terminal to the standby state. The first threshold may be, for example, a remaining battery amount (or a remaining battery amount obtained by adding a margin to the remaining battery amount) that is assumed to potentially impair the operation of the communication terminal and / or an auxiliary device if the first battery remaining amount falls below the first threshold, or may be a remaining battery amount (or a remaining battery amount obtained by adding a margin to the remaining battery amount) that is assumed to potentially promote deterioration of the first battery. Furthermore, when the first battery remaining amount is less than the first threshold and the second battery remaining amount is equal to or greater than a second threshold, the control unit may control the communication terminal to the standby state while charging the first battery from the second battery. For example, the second threshold may be a remaining battery charge that is assumed to cause a problem in running the vehicle if the remaining battery charge falls below the second threshold (or a remaining battery charge obtained by adding a margin to the remaining battery charge). Furthermore, when the remaining first battery charge is less than the first threshold and the remaining second battery charge is less than the second threshold, the control unit may control the communication terminal to a stopped state.

[0015] According to the information processing device of the present disclosure, even if the remaining charge of the first battery falls below the first threshold after the vehicle is stopped, the communication terminal can continue to wait in a standby state as long as the remaining charge of the second battery is equal to or greater than the second threshold. This increases the opportunities for the communication terminal to continue waiting in a standby state while suppressing interference with the operation of the communication terminal and / or auxiliary equipment and promoting deterioration of the first battery. As a result, the user's convenience when remotely operating the vehicle can be improved.

[0016] In a vehicle equipped with the second battery described above, the second battery may be charged using an external power source while the vehicle is stopped. Therefore, after the communication terminal is controlled to a stopped state because the first battery remaining charge is less than the first threshold and the second battery remaining charge is less than the second threshold, the second battery may be charged by the external power source, causing the second battery remaining charge to increase to or above the second threshold. Therefore, in the information processing device according to the present disclosure, after the communication terminal is controlled to a stopped state because the first battery remaining charge is less than the first threshold and the second battery remaining charge is less than the second threshold, the control unit may switch the communication terminal from a stopped state to a standby state while charging the first battery from the second battery. This can more reliably increase the opportunities for the communication terminal to remain in standby mode. As a result, the user's convenience when remotely operating the vehicle can be more reliably improved.

[0017] <Embodiment> Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. The configurations of the following embodiments are illustrative, but the embodiments described below are merely examples of the present disclosure in all respects. Various improvements or modifications may be made without departing from the scope of the present disclosure. When implementing the present disclosure, specific configurations according to the embodiments may be appropriately adopted. Note that while data appearing in the present embodiments are described in natural language, more specifically, they may be specified using computer-recognizable pseudo-language, commands, parameters, machine language, etc.

[0018] (System configuration) 1 is a diagram schematically illustrating an example of the configuration of a system to which the present disclosure is applied. The system according to this embodiment includes a vehicle 10, a user terminal 20, and a server 30, and provides a remote service to a user of the vehicle 10. The remote service is a service that allows a user to remotely operate the vehicle 10 via the user terminal 20.

[0019] The vehicle 10, the user terminal 20, and the server 30 are connected via a network N1. The network N1 is, for example, a WAN (Wide Area Network), which is a global public communication network such as the Internet, or other communication network. 1 shows only one vehicle 10 and one user terminal 20, the system may include a plurality of vehicles 10 and user terminals 20 under the management of the server 30.

[0020] The vehicle 10 is a BEV equipped with an auxiliary battery 120 and a driving battery 130. The vehicle 10 is not limited to a BEV, and may be a PHEV equipped with an auxiliary battery and a driving battery. The vehicle 10 has a function of operating the in-vehicle equipment 160 in accordance with a remote command signal transmitted from the server 30. The vehicle 10 in this embodiment also has a function of switching the communication terminal 110 between a standby state (a state in which the remote command signal transmitted from the server 30 can be received) and a stopped state (a state in which the remote command signal transmitted from the server 30 cannot be received) according to the remaining battery power of the auxiliary battery 120 and the driving battery 130. Details of the vehicle 10 will be described later.

[0021] The user terminal 20 is a computer used by the user of the vehicle 10, and has a function of accepting remote operations performed by the user and a function of transmitting a remote operation signal including information about the accepted remote operation (e.g., a method of operating an in-vehicle device that is the target of the remote operation) to the server 30. Such a user terminal 20 may be, for example, a terminal carried by the user (e.g., a smartphone, a tablet terminal, etc.).

[0022] The server 30 is one or more computers that perform processing related to the remote operation of the vehicle 10. In response to receiving a remote operation signal transmitted from the user terminal 20, the server 30 has a function of transmitting to the vehicle 10 a remote command signal for operating the on-board equipment of the target vehicle 10 according to the operation method contained in the remote operation signal.

[0023] (Vehicle configuration) The vehicle 10 in this embodiment is equipped with a power management device 100, a communication terminal 110, an auxiliary battery 120, a driving battery 130, a DC / DC converter 140, an ECU 150, on-board equipment 160, a power switch 170, and an electric motor 180. The power management device 100, the communication terminal 110, the auxiliary battery 120, the driving battery 130, the DC / DC converter 140, the ECU 150, the on-board equipment 160, and the power switch 170 are connected to each other via a CAN (Controller Area Network), a LIN (Local Interconnect Network), or a FlexRay. These are interconnected through an in-vehicle network based on standards such as:

[0024] The power management device 100 can be configured as a computer having a processor (CPU, GPU, etc.), a main memory (RAM, ROM, etc.), and an auxiliary memory (EPROM, hard disk drive, removable media, etc.). In one example, the power management device 100 is configured by combining one or more ECUs (Electronic Control Units). In this embodiment, the power management device 100 corresponds to the information processing device according to the present disclosure. The power management device 100 includes a control unit 101, a storage unit 102, and a communication I / F 103.

[0025] The control unit 101 executes dedicated programs stored in the storage unit 102 to realize various functions of the power management device 100. The control unit 101 can be realized by a hardware processor such as a CPU or a DSP. The control unit 101 may also be configured to include RAM, ROM (Read Only Memory), cache memory, and the like in addition to the hardware processor. Details of the functions realized by the control unit 101 will be described later.

[0026] The storage unit 102 includes an auxiliary storage device and stores various types of information. The storage unit 102 may be a storage area built in the auxiliary storage device. The information stored in the storage unit 102 includes, in addition to the OS, a dedicated program for controlling the state of the communication terminal 110, data used by the program, and the like.

[0027] The communication I / F 103 includes a communication interface for connecting the power management device 100 to an in-vehicle network. The communication I / F 103 of this embodiment communicates with each of the communication terminal 110, the auxiliary battery 120, and the drive battery 130 via the in-vehicle network.

[0028] Next, the communication terminal 110 of the vehicle 10 is a computer having a function of communicating with the server 30 through an external network and a function of communicating with the power management device 100 through an internal network. The communication terminal 110 has a function of transmitting a remote command signal received from the server 30 to the ECU 150. Furthermore, in this embodiment, the communication terminal 110 has a function of switching between a standby state and a stopped state in accordance with a command from the power management device 100.

[0029] The auxiliary battery 120 of the vehicle 10 is a secondary battery that supplies power to electrical components (auxiliaries) such as the communication terminal 110, door lock actuators, power window actuators, a car navigation system, lighting devices, wipers, etc. The auxiliary battery 120 is configured to be chargeable using power from the drive battery 130. In this embodiment, the auxiliary battery 120 corresponds to the first battery according to the present disclosure.

[0030] The drive battery 130 of the vehicle 10 is a secondary battery that supplies power to the electric motor 180, which will be described later. The drive battery 130 is configured to be chargeable using power generated (regenerative power generation) by converting the kinetic energy of the drive wheels when the vehicle 10 is decelerating into electrical energy, and power supplied from an external power source. In this embodiment, the drive battery 130 corresponds to the second battery according to the present disclosure.

[0031] When charging the auxiliary battery 120 from the drive battery 130, the DC / DC converter 140 of the vehicle 10 converts the voltage supplied from the drive battery 130 to the auxiliary battery 120 into a voltage suitable for the auxiliary battery 120.

[0032] The ECU 150 of the vehicle 10 is a computer that controls the in-vehicle devices 160. The in-vehicle devices 160 include an air conditioner, a door lock actuator, a power window actuator, and the like that are mounted on the vehicle 10. The ECU 150 operates the in-vehicle devices 160 in accordance with a remote command signal that the communication terminal 110 receives from the server 30.

[0033] The power switch 170 of the vehicle 10 is a switch that allows the user to switch between operating the vehicle 10 (power switch 170 is on) and stopping the operation of the vehicle 10 (power switch 170 is off).

[0034] The electric motor 180 is a motor for driving the drive wheels of the vehicle 10. Note that the electric motor 180 may be a motor-generator that functions as a motor for driving the drive wheels and as a generator for converting the kinetic energy of the drive wheels into electrical energy.

[0035] (Power management device function) Next, a detailed description will be given of the functions realized by the control unit 101 of the power management device 100. Note that the functions described below may be realized by a hardware circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array).

[0036] The control unit 101 of the power management device 100 in this embodiment has the function of controlling the charging and discharging of the auxiliary battery 120 and the driving battery 130, as well as the function of controlling the charging from the driving battery 130 to the auxiliary battery 120, and the function of controlling the state of the communication terminal 110 when the vehicle 10 is in a stopped state.

[0037] Here, a description will be given of a function for controlling charging from the driving battery 130 to the auxiliary battery 120. The control unit 101 acquires the remaining battery capacity of each of the auxiliary battery 120 and the driving battery 130 at a predetermined cycle (for example, every several hundred milliseconds to several minutes). The remaining battery capacity at this time may be, for example, the SOC of each of the auxiliary battery 120 and the driving battery 130.

[0038] The control unit 101 determines whether the remaining battery capacity of the auxiliary battery 120 (hereinafter, sometimes referred to as "first remaining battery capacity") is less than the first threshold value and whether the remaining battery capacity of the drive battery 130 is less than the first threshold value. When the remaining battery charge of 0 (hereinafter, sometimes referred to as "second remaining battery charge") is equal to or greater than a second threshold, the control unit 101 controls the DC / DC converter 140 so that the auxiliary battery 120 is charged from the driving battery 130. Specifically, the control unit 101 controls the DC / DC converter 140 so that the voltage supplied from the driving battery 130 to the auxiliary battery 120 is converted to a voltage suitable for the auxiliary battery 120. Note that, as an example, the "first threshold" here may be a remaining battery charge that is estimated to have the potential to cause interference with the operation of the communication terminal 110 and / or the in-vehicle device 160 if the first remaining battery charge falls below the first threshold, or a remaining battery charge obtained by adding a margin to the remaining battery charge. As another example, the "first threshold" may be a remaining battery charge that is estimated to have the potential to accelerate deterioration of the auxiliary battery 120, or a remaining battery charge obtained by adding a margin to the remaining battery charge. In addition, the "second threshold" may be, for example, a battery remaining charge that is estimated to cause a disruption to the running of the vehicle 10 if the second battery remaining charge falls below the second threshold, or a battery remaining charge that is the battery remaining charge plus a margin.

[0039] If the first battery remaining charge increases to or above a first threshold after charging of the auxiliary battery 120 from the driving battery 130 has started, the control unit 101 controls the DC / DC converter 140 to stop charging of the auxiliary battery 120 from the driving battery 130. Note that if the second battery remaining charge decreases to or below a second threshold before the first battery remaining charge increases to or above the first threshold, the control unit 101 may stop charging of the auxiliary battery 120 from the driving battery 130 at the time the second battery remaining charge drops below the second threshold. However, when the second battery is being charged by an external power source, charging of the auxiliary battery 120 from the driving battery 130 may continue until the first battery remaining charge increases to or above the first threshold.

[0040] Next, the function of controlling the state of the communication terminal 110 when the vehicle 10 is in a stopped state will be described with reference to Fig. 2. Fig. 2 is a diagram showing the conditions under which the communication terminal 110 is controlled to the standby state and the stopped state. The control unit 101 has a function of repeatedly executing the following process at a predetermined cycle (for example, from several hundred milliseconds to several minutes) in response to the power switch 170 being switched from on to off.

[0041] First, the control unit 101 acquires a first remaining battery capacity, which is the remaining battery capacity of the auxiliary battery 120, and a second remaining battery capacity, which is the remaining battery capacity of the drive battery 130. In one example, the control unit 101 calculates the SOC of each of the auxiliary battery 120 and the drive battery 130 using a known method such as the OCV method or the current integration method, and acquires these SOCs as the first remaining battery capacity and the second remaining battery capacity, respectively.

[0042] Next, the control unit 101 determines whether the first battery remaining charge is equal to or greater than a first threshold. If it is determined that the first battery remaining charge is equal to or greater than the first threshold, the control unit 101 controls the communication terminal 110 to be in a standby state by supplying power from the auxiliary battery 120 to the communication terminal 110. As a result, if the first battery remaining charge is equal to or greater than the first threshold, the communication terminal 110 is controlled to be in a standby state, as shown in FIG. 2, regardless of whether the second battery remaining charge is equal to or greater than a second threshold. Furthermore, charging from the driving battery 130 to the auxiliary battery 120 is not performed.

[0043] Furthermore, when it is determined that the first battery remaining capacity is less than the first threshold, the control unit 101 determines whether the second battery remaining capacity is equal to or greater than the second threshold. When it is determined that the second battery remaining capacity is equal to or greater than the second threshold, the control unit 101 charges the auxiliary battery 120 by supplying power from the driving battery 130 to the auxiliary battery 120 through the DC / DC converter 140, and controls the communication terminal 110 to be in a standby state by supplying power from the auxiliary battery 120 to the communication terminal 110. As a result, when the first battery remaining capacity is less than the first threshold, If the second battery remaining charge is equal to or greater than the second threshold, the communication terminal 110 is controlled to a standby state on the condition that the auxiliary battery 120 is charged from the driving battery 130, as shown in FIG. 2.

[0044] Furthermore, when it is determined that the second battery remaining capacity is less than the second threshold, the control unit 101 stops the supply of power from the auxiliary battery 120 to the communication terminal 110 and controls the communication terminal 110 to a stopped state. As a result, when the first battery remaining capacity is less than the first threshold and the second battery remaining capacity is less than the second threshold, the communication terminal 110 is controlled to a stopped state as shown in FIG.

[0045] The second battery remaining capacity may be acquired only when it is determined that the first battery remaining capacity is less than the first threshold value. In other words, when it is determined that the first battery remaining capacity is equal to or greater than the first threshold value, the second battery remaining capacity may not be acquired.

[0046] In this embodiment, even after communication terminal 110 is controlled to the stopped state, control unit 101 acquires the first battery remaining amount, acquires the second battery remaining amount, determines whether the first battery remaining amount is equal to or greater than the first threshold, and determines whether the second battery remaining amount is equal to or greater than the second threshold, at predetermined intervals. As a result, when driving battery 130 is charged by an external power source and the second battery remaining amount increases to equal to or greater than the second threshold, control unit 101 can return communication terminal 110 from the stopped state to the standby state while charging auxiliary battery 120 from driving battery 130.

[0047] Here, Figure 3 shows an example of a time chart of the remaining charge of the first battery, the remaining charge of the second battery, the charge state of the auxiliary battery 120, the charge state of the driving battery 130, and the state of the communication terminal 110 after the power switch 170 is switched from on to off.

[0048] 3, during the period from the time when power switch 170 is switched from on to off (t1 in FIG. 3) to the time when the first battery remaining charge decreases to less than the first threshold (t2 in FIG. 3), the auxiliary battery 120 is not charged from the driving battery 130, and the communication terminal 110 is controlled to a standby state (power is supplied from the auxiliary battery 120 to the communication terminal 110). During the period from the time when the first battery remaining charge decreases to less than the first threshold (t2 in FIG. 3) to the time when the first battery remaining charge increases to or exceeds the first threshold (t3 in FIG. 3), the auxiliary battery 120 is charged from the driving battery 130, and the communication terminal 110 is maintained in a standby state. During the period from the time when the first battery remaining charge increases to or exceeds the first threshold (t3 in FIG. 3) to the time when the first battery remaining charge again falls below the first threshold (t4 in FIG. 3), charging of the auxiliary battery 120 from the driving battery 130 is stopped, and the standby state of the communication terminal 110 is maintained. Thereafter, when the first battery remaining charge again falls below the first threshold (t4 in FIG. 3), charging of the auxiliary battery 120 from the driving battery 130 is resumed, and the standby state of the communication terminal 110 is maintained. Charging of the auxiliary battery 120 from the driving battery 130 is repeatedly executed in this manner, and when the second battery remaining charge falls below the second threshold (t5 in FIG. 3), charging of the auxiliary battery 120 from the driving battery 130 is terminated. 3, if the remaining charge of the first battery is less than the first threshold at the time when the remaining charge of the second battery falls below the second threshold (t5 in FIG. 3), communication terminal 110 is switched from the standby state to the stopped state. Thereafter, charging of drive battery 130 by an external power source begins (t6 in FIG. 3), and when the remaining charge of the second battery increases to or above the second threshold (t7 in FIG. 3), charging of auxiliary battery 120 from drive battery 130 resumes, and communication terminal 110 is switched from the stopped state to the standby state.

[0049] In the example shown in FIG. 3, charging from the drive battery 130 to the auxiliary battery 120 Although charging from the driving battery 130 to the auxiliary battery 120 is stopped when the first battery remaining charge increases to or exceeds the first threshold (t3 in FIG. 3), charging from the driving battery 130 to the auxiliary battery 120 may be continued until the second battery remaining charge decreases to or below the second threshold, regardless of whether the first battery remaining charge is equal to or above the first threshold. In this case, if the first battery remaining charge is equal to or above the first threshold when the second battery remaining charge decreases to or below the second threshold, the standby state of the communication terminal 110 may be maintained until the first battery remaining charge decreases to or below the first threshold.

[0050] Furthermore, in the example shown in FIG. 3, when the remaining charge of the second battery increases to a second threshold or more due to charging of the driving battery 130 from an external power source (t7 in FIG. 3), charging of the auxiliary battery 120 from the driving battery 130 is resumed and the communication terminal 110 is switched from a stopped state to a standby state; however, when the remaining charge of the second battery increases to a fourth threshold or more that is larger than the second threshold, charging of the auxiliary battery 120 from the driving battery 130 may be resumed and the communication terminal 110 may be switched from a stopped state to a standby state.

[0051] (Processing flow) Next, the flow of processing executed by the power management device 100 in this embodiment will be described with reference to Fig. 4. Fig. 4 is a flowchart showing an example of a processing routine that is repeatedly executed at a predetermined interval by the power management device 100 when the vehicle 10 is in an operation-stopped state (the power switch 170 is in an off state).

[0052] 4, the control unit 101 first calculates the SOC of the auxiliary battery 120 and acquires the calculated SOC as the first battery remaining capacity (step S101). After completing the process of step S101, the control unit 101 executes the process of step S102.

[0053] In step S102, the control unit 101 determines whether the first remaining battery charge acquired in step S101 is equal to or greater than a first threshold. As described above, the first threshold may be a remaining battery charge (or a remaining battery charge obtained by adding a margin to the remaining battery charge) that is assumed to potentially impair the operation of the communication terminal 110 and / or the in-vehicle device 160 if the first remaining battery charge falls below the first threshold, or may be a remaining battery charge (or a remaining battery charge obtained by adding a margin to the remaining battery charge) that is assumed to potentially accelerate deterioration of the auxiliary battery 120. If the first remaining battery charge is equal to or greater than the first threshold (positive determination in step S102), the control unit 101 executes the process of step S103. On the other hand, if the first remaining battery charge is less than the first threshold (negative determination in step S102), the control unit 101 executes the process of step S104.

[0054] In step S103, the control unit 101 controls the communication terminal 110 to be in a standby state by supplying power from the auxiliary battery 120 to the communication terminal 110. After completing the processing of step S103, the control unit 101 temporarily ends the execution of this processing routine.

[0055] Furthermore, in step S104, the control unit 101 calculates the SOC of the driving battery 130 and acquires the calculated SOC as the second battery remaining capacity. After completing the process of step S104, the control unit 101 executes the process of step S105.

[0056] In step S105, the control unit 101 determines whether the second remaining battery charge obtained in step S104 is equal to or greater than the second threshold. As described above, the second threshold may be a battery charge that is assumed to cause a problem in driving the vehicle 10 if the second remaining battery charge falls below the second threshold, or a battery charge that is the battery charge with a margin added thereto. If the remaining battery charge is equal to or greater than the second threshold (positive determination in step S105), the control unit 101 executes the process of step S106. On the other hand, if the remaining second battery charge is less than the second threshold (negative determination in step S105), the control unit 101 executes the process of step S107.

[0057] In step S106, control unit 101 controls DC / DC converter 140 so that the auxiliary battery 120 is charged from drive battery 130. Specifically, control unit 101 controls DC / DC converter 140 so that the voltage supplied from drive battery 130 to auxiliary battery 120 is converted into a voltage suitable for auxiliary battery 120. After completing the processing of step S106, control unit 101 proceeds to the processing of step S103, and controls communication terminal 110 to be in a standby state.

[0058] Furthermore, in step S107, the control unit 101 controls the communication terminal 110 to a stopped state by stopping the supply of power from the auxiliary battery 120 to the communication terminal 110. After completing the processing of step S107, the control unit 101 temporarily ends the execution of this processing routine.

[0059] 2 and 3, communication terminal 110 can be kept in standby mode not only during the period when the first battery remaining charge is equal to or greater than the first threshold, but also during the period when the first battery remaining charge is less than the first threshold and the second battery remaining charge is equal to or greater than the second threshold. This allows communication terminal 110 to be kept in standby mode during the period from when vehicle 10 is stopped (power switch 170 is turned from on to off) until the first battery remaining charge falls below the first threshold, and also during the period from when the first battery remaining charge falls below the first threshold until the second battery remaining charge falls below the second threshold. Furthermore, even after the second battery remaining charge falls below the second threshold, charging drive battery 130 from an external power source can cause communication terminal 110 to automatically return from the stopped state to the standby state when the second battery remaining charge increases to equal to or greater than the second threshold.

[0060] Therefore, according to the present embodiment, it is possible to increase the opportunities for the communication terminal 110 to be kept in standby mode while suppressing interference with the operation of the communication terminal 110 and the auxiliary equipment and promoting deterioration of the auxiliary equipment battery 120. As a result, it is possible to improve the convenience for users of the service.
