Control device for lock device

Abstract

The invention relates to a control device of a locking device. An ECU is a control device for a lock mechanism that fixes a connector such as an AC power supply connector to an access port of a vehicle. The connector includes an AC power supply connector for supplying power to electrical equipment external to the vehicle. And if the locking mechanism is controlled to be switched to the unlocking state in the power supply process under the locking state of the locking mechanism, power supply to the external electrical equipment is stopped. The ECU performs control so as to switch the lock mechanism to the unlocked state when a first operation (an operation in which a connector unlocking condition is satisfied during non-power-supply) is performed during the non-power-supply process in the locked state, and maintains the locked state of the lock device when the first operation is performed during the power-supply process in the locked state.

Description

Technical Field

[0001] The disclosure relates to a control device for a locking device, and more particularly to a control device for a locking device for fixing a connector to an access port of a vehicle. Background Art

[0002] Conventionally, there are vehicles that stop charging when the charging connector is unlocked (see, for example, Japanese Patent Application Laid-Open No. 2020-141483). In such a vehicle, if the connector is not removed after being unlocked, the connector automatically becomes locked again and charging starts again. Summary of the invention

[0003] However, when power is supplied from the vehicle to an external device, if the power supply is stopped, even temporarily, there is a possibility that the convenience of the user will be reduced.

[0004] This disclosure has been made to solve the above-mentioned problems, and an object of the disclosure is to provide a control device for a locking device that can avoid an unexpected stop of power supply during power supply to an external device.

[0005] The disclosed locking device control device is a locking device control device that fixes a connector to an inlet of a vehicle.

[0006] The connector includes a connector for supplying power to a device outside the vehicle.

[0007] If the lock device is controlled to be switched to the unlocked state while power is being supplied in the locked state of the lock device, power supply to the external device is stopped.

[0008] When a first operation is performed in the locked state and no power is supplied, the control device controls the locking device to be switched to the unlocked state.

[0009] When the first operation is performed while power is supplied in the locked state, the control device maintains the locked state of the locking device.

[0010] According to such a structure, when the first operation is performed in the locked state and the power supply is not being supplied, the locking device is switched to the unlocked state, and the power supply to the external device is stopped. On the other hand, when the first operation is performed in the locked state and the power supply is being supplied, the locked state of the locking device is maintained, so the power supply to the external device is not stopped. As a result, a control device for the locking device can be provided, which can avoid the unexpected stop of the power supply to the external device.

[0011] Alternatively, when a second operation different from the first operation is performed during power supply in the locked state, the control device may control the locking device to be switched to the unlocked state. According to such a structure, when a second operation different from the first operation is performed, even during power supply, it can be determined that the user intends to stop power supply and switch the locking device to the unlocked state, thereby switching to the unlocked state.

[0012] Alternatively, when the first operation is performed multiple times during power supply in the locked state, the control device may control the locking device to be switched to the unlocked state. According to such a structure, when the first operation for switching to the unlocked state is performed multiple times during non-power supply, it can be determined that the user intends to stop power supply and switch the locking device to the unlocked state even during power supply. Then, the unlocked state can be switched.

[0013] When the first operation is performed during power supply in the locked state, the control device may perform processing for notifying the operation required to switch the lock device to the unlocked state. According to such a configuration, the user can be informed of the operation required to switch to the unlocked state during power supply.

[0014] The control device can also control the locking device to be switched to the unlocked state when the second operation is performed in the locked state and the power is not supplied. According to such a structure, when the second operation is performed, the locking device can be switched to the unlocked state not only in the power supply but also in the non-power supply.

DETAILED DESCRIPTION

[0022] Hereinafter, the embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. It should be noted that the same or corresponding parts in the drawings are denoted by the same reference numerals, and their description will not be repeated.

[0023] Hereinafter, a configuration of an electric vehicle (hereinafter referred to as a vehicle) 200 according to the present embodiment will be described. Figure 1 2 is a diagram showing an example of the structure of a vehicle 200 in this embodiment. The vehicle 200 includes, for example, an electric vehicle that can transfer electric power to and from an electric device outside the vehicle 200, such as a plug-in hybrid electric vehicle and a battery electric vehicle. Figure 1 In the example, a case where the vehicle 200 is parked in a parking space where the power supply equipment 10 is installed is assumed.

[0024] like Figure 1 As shown, vehicle 200 includes ECU (Electronic Control Unit) 100 , inlet 202 , power conversion device 204 , lock mechanism 206 , battery 214 , inverter 216 , motor generator (MG) 218 ​​, HMI (Human Machine Interface) 130 , and wireless communication unit 150 .

[0025] Motor generator 218 is, for example, a three-phase AC rotating electric machine, and has a function as an electric motor and a function as a generator. That is, electric power is transferred between motor generator 218 and inverter 216 .

[0026] For example, when the vehicle 200 is driven, the motor generator 218 uses the electric power supplied from the inverter 216 to provide a rotational force to the drive wheel 222. The drive wheel 222 rotates by the rotational force applied by the motor generator 218, so that the vehicle 200 travels. It should be noted that the number of the motor generators 218 is not limited to one, and a plurality of motor generators may be provided.

[0027] The inverter 216 converts electric power bidirectionally between the motor generator 218 and the battery 214 according to a control signal from the ECU 100. For example, when the motor generator 218 is driven, the inverter 216 converts the DC power of the battery 214 into AC power and supplies it to the motor generator 218. In addition, when the motor generator 218 generates electricity, the inverter 216 converts the AC power (regenerative power) generated in the motor generator 218 into DC power and supplies it to the battery 214. It should be noted that a converter that adjusts the voltage of the inverter 216 and the voltage of the battery 214 may be provided between the inverter 216 and the battery 214.

[0028] The battery 214 is, for example, a rechargeable storage element, and typically, a secondary battery such as a nickel-metal hydride battery or a lithium-ion battery having a solid or liquid electrolyte is used. Alternatively, the battery 214 may be a storage device capable of storing electricity, and, for example, a large-capacity capacitor may be used instead of the battery 214.

[0029] The battery 214 is externally charged using the power supplied from the power supply device 10. External charging includes AC charging and DC charging. AC charging is charging using the DC power supplied from the external device (power supply device 10) to the inlet 202 after being converted in the power conversion device 204. DC charging is charging using the DC power supplied from the power supply device 10 to the inlet 202 without passing through the power conversion device 204.

[0030] The access port 202 is provided together with a cover such as a lid (not shown) on the exterior of the vehicle 200, and is configured to be able to mount various connectors described later. The access port 202 is configured to be able to transfer power to and from a device outside the vehicle 200 (hereinafter referred to as an external device). Here, "capable of transferring power" means that at least one of charging or discharging can be performed. That is, the access port 202 can receive power from the external device for charging the battery 214. Furthermore, the access port 202 can supply (discharge, supply) power from the battery 214 to the external device.

[0031] The inlet 202 has a shape that can be mounted on any of the AC charging connector 17 for AC charging, the DC charging connector 18 for DC charging, and the AC power supply connector 19 for AC power supply. It should be noted that AC power supply refers to external power supply that supplies AC power from the vehicle 200 to an external device (for example, an electrical device 21). The inlet 202 is provided with AC connection parts 202a, 202b, DC connection parts 202f, 202g, and communication parts 202c to 202e.

[0032] When the AC charging connector 17 of the power supply device 10 is mounted on the inlet 202, the AC connection portion (see Figure 2 ) is electrically connected to the AC connection parts 202a, 202b of the inlet 202, and the communication part of the AC charging connector 17 (refer to Figure 2 ) are connected to the communication units 202c to 202e of the access port 202.

[0033] When DC charging connector 18 of power supply device 10 is mounted on inlet 202 , the AC connection portion of DC charging connector 18 is electrically connected to AC connection portions 202 a and 202 b of inlet 202 , and the communication portion of DC charging connector 18 is connected to communication portions 202 c to 202 e of inlet 202 .

[0034] Furthermore, when the AC power supply connector 19 is installed in the inlet 202, the AC connection part of the AC power supply connector 19 is electrically connected to the AC connection parts 202a and 202b of the inlet 202, and the communication part of the AC power supply connector 19 is connected to the communication parts 202c and 202d of the inlet 202. One end of the AC power supply connector 19 is formed in a shape that can be installed in the inlet 202, and a socket 20 is provided at the other end of the AC power supply connector 19. The socket 20 has a shape that can connect a plug 22 of an electrical device 21. It should be noted that the electrical device 21 includes, for example, a household electrical appliance that operates at AC100V.

[0035] The power conversion device 204 performs power conversion between the battery 214 and the inlet 202 according to the control signal from the ECU 100. For example, when the battery 214 is charged with AC power with the AC charging connector 17 attached to the inlet 202, the power conversion device 204 converts the AC power supplied from the AC charging connector 17 into DC power. Then, the battery 214 is charged with the converted DC power.

[0036] Furthermore, the power conversion device 204 converts the DC power supplied from the battery 214 into AC power, for example, when the AC power supply connector 19 is installed at the inlet 202 and the plug 22 of the electrical device 21 is connected to the socket 20 of the AC power supply connector 19. Then, the converted AC power (for example, AC 100V) is supplied to the electrical device 21.

[0037] The locking mechanism 206 restricts the removal of the connector installed in the access port 202 and becomes a state fixed to the access port 202 (locked state). The locking mechanism 206 releases the restriction on the removal of the connector and becomes a state in which the connector can be removed from the access port 202 (unlocked state). An actuator is provided in the locking mechanism 206. The actuator, for example, moves a member to a position that restricts the movement of the connector installed in the access port 202 to set it to a locked state, or moves the member to a position that allows the movement of the connector installed in the access port 202 to set it to an unlocked state. That is, the locking mechanism 206 switches from one state of the locked state and the unlocked state to the other state according to a control signal from the ECU 100.

[0038] ECU100 has a built-in CPU (Central Processing Unit) 101, a memory (e.g., including ROM (Read Only Memory), RAM (Random Access Memory), etc.) 102, and an interface 103. Based on information such as mapping and programs stored in the memory 102 and information from various sensors received by the interface 103, ECU100 outputs signals from the interface 103 to control various devices (e.g., power conversion device 204, locking mechanism 206, or inverter 216) in such a way that the vehicle 200 is in a desired state. It should be noted that the various controls performed by ECU100 are not limited to software-based processing, and dedicated hardware (electronic circuits) can also be constructed to perform processing.

[0039] Furthermore, when a connector (AC charging connector 17, DC charging connector 18, or AC power supply connector 19) is installed at the inlet 202, the ECU 100 performs a communication process of receiving predetermined information from the device (power supply device 10) on the connector side using the interface 103. The predetermined information includes, for example, information related to the power that can be transferred between the power supply device 10 and the battery 214.

[0040] For example, when the AC charging connector 17 is installed in the inlet 202, the ECU 100 receives predetermined information from the power supply device 10 (more specifically, the AC charging connector 17) using the interface 103. The predetermined information includes: information indicating that the communication unit of the AC charging connector 17 is connected to the communication units 202c, 202d, and 202e of the inlet 202, and that the power transmitted and received between the installed AC charging connector 17 and the inlet 202 is AC power; and information indicating that the power transmitted and received between the AC charging connector 17 and the inlet 202 is charging power for charging the battery 214.

[0041] Alternatively, for example, when the DC charging connector 18 is installed at the inlet 202, the ECU 100 receives predetermined information from the power supply device 10 (more specifically, the DC charging connector 18) using the interface 103. The predetermined information includes: information indicating that the communication unit of the DC charging connector 18 is connected to the communication units 202c, 202d, and 202f of the inlet 202, and that the power transmitted and received between the DC charging connector 18 installed from the power supply device 10 and the inlet 202 is DC power; and information indicating that the power transmitted and received between the DC charging connector 18 and the inlet 202 is charging power.

[0042] Alternatively, for example, when the AC power supply connector 19 is installed in the inlet 202, the ECU 100 receives predetermined information from the AC power supply connector 19 using the interface 103. The predetermined information includes: information indicating that the communication unit of the AC power supply connector 19 is connected to the communication units 202c and 202d of the inlet 202, and that the power transmitted and received between the installed AC power supply connector 19 and the inlet 202 is AC power; and information indicating that the power transmitted and received between the AC power supply connector 19 and the inlet 202 is discharge power for discharging the battery 214.

[0043] When AC charging connector 17 of power supply equipment 10 is mounted on inlet 202 of vehicle 200, power supply equipment 10 supplies AC power to inlet 202. The AC power supplied to inlet 202 is converted into DC power by power conversion device 204. The converted DC power is supplied to battery 214, and battery 214 is charged.

[0044] When DC charging connector 18 of power supply facility 10 is attached to inlet 202 of vehicle 200, power supply facility 10 supplies DC power to inlet 202. The DC power supplied to inlet 202 is supplied to battery 214 without passing through power conversion device 204, and battery 214 is charged.

[0045] HMI 130 is constituted by a touch panel display, displays information received from ECU 100 on the display, and transmits information received by the touch panel to ECU 100 .

[0046] The wireless communication unit 150 is controlled by the ECU 100 and receives wireless signals from other devices such as the terminal device 800, a server or another vehicle 200. The wireless communication unit 150 converts the received wireless signal into data, stores the converted data in the memory 102, or transmits the converted data to the HMI 130 for displaying the data, and converts the transmitted data into a wireless signal and transmits it to other devices at the data communication destination.

[0047] The terminal device 800 includes a CPU (Central Processing Unit) 810, a memory 820, an input unit 830, an output unit 840, a wireless communication unit 850, and an external storage device 860. The CPU 810, the memory 820, the input unit 830, the output unit 840, the wireless communication unit 850, and the external storage device 860 are connected to each other via a bus.

[0048] The memory 820 includes a RAM (Random Access Memory) used as a work area required for the CPU 810 to execute a program and a ROM (Read Only Memory) for storing a program to be executed by the CPU 810. In addition, a program and data for executing a predetermined process are read from the ROM and stored in the RAM.

[0049] The input unit 830 includes a touch panel and operation buttons for inputting numbers, letters, other characters, etc. such as telephone numbers and various data. It should be noted that the input unit 830 may also include a portion for other operations. When the user operates the input unit 830, an operation signal corresponding to the operation is sent from the input unit 830 to the CPU 810. The CPU 810 controls each part of the terminal device 800 according to the operation signal from the input unit 830.

[0050] The output unit 840 includes a display and a speaker. The display is formed integrally with the aforementioned touch panel. The output unit 840 is controlled by the CPU 810. The output unit 840 displays the information received by the wireless communication unit 850, the information stored in the memory 820, or the information read from the recording medium by the external storage device 860 as an image signal and a sound signal converted by the CPU 810 on the display as an image, and outputs it as a sound from the speaker.

[0051] The wireless communication unit 850 is controlled by the CPU 810 and receives wireless signals from other terminal devices 800 or fixed telephones of the other party of the call via the public line and the antenna. The wireless communication unit 850 converts the received wireless signals into voice signals and sends the converted voice signals to the voice input and output unit. The wireless communication unit 850 converts the voice signals from the voice input and output unit into wireless signals and sends them to other terminal devices 800 or fixed telephones of the other party of the call via the antenna and the communication equipment of the telecommunications operator.

[0052] In addition, the wireless communication unit 850 is controlled by the CPU 810 and receives wireless signals from devices capable of data communication, such as the vehicle 200, a server, or other terminal devices 800, via a public line and an antenna. The wireless communication unit 850 converts the received wireless signal into data, stores the converted data in the memory 820, or transmits it to the output unit 840 for displaying the data. The wireless communication unit 850 converts the transmitted data into a wireless signal and transmits it to the vehicle 200, server, or other terminal device 800 at the data communication destination via an antenna and a communication device of a telecommunications operator.

[0053] The external storage device 860 is composed of a memory card reader / writer. The external storage device 860 electrically records the predetermined data or program received from the CPU 810 in a storage medium such as a memory card or a USB (Universal Serial Bus) memory, or reads it from the recording medium and transfers it to the CPU 810. It should be noted that the external storage device 860 can also be composed of a storage device such as a hard disk drive, a floppy disk drive, an MO (Magneto-Optical disk) drive, a CD (CompactDisc) drive, or a DVD (Digital Versatile Disk) drive.

[0054] The CPU 810 executes predetermined processing according to the program and data stored in the memory 820 or the recording medium of the external storage device 860, and processes the data input from the input unit 830 or the wireless communication unit 850. The CPU 810 stores the processed data in the memory 820, outputs the processed data from the wireless communication unit 850 to other devices, or stores the processed data in the recording medium of the external storage device 860.

[0055] It should be noted that the terminal device 800 is described as a portable terminal such as a smartphone, but the present invention is not limited thereto and may be another information processing device such as a PC (Personal Computer) or a tablet computer.

[0056] In the vehicle 200 described above, it is considered that when the AC charging connector 17, the DC charging connector 18, or the AC power supply connector 19 is set to the unlocked state, the charging or power supply is stopped while the charging or power supply is in progress. In this case, it is considered that after the AC charging connector 17, the DC charging connector 18, or the AC power supply connector 19 is set to the unlocked state, it is automatically set to the locked state again, and the charging is restarted. In this way, in the electrical device 21, it is set that even if the power supply is restarted, it is set that it is difficult to stop.

[0057] However, in particular, when power is being supplied from the vehicle 200 to the external electrical device 21, if the power supply is stopped, even temporarily, there is a possibility that the convenience of the user will be reduced. For example, when cooking rice with a rice cooker as the external electrical device 21, when the door is unlocked to take out the items placed in the vehicle, if the power supply is stopped, even if the power supply is automatically restarted, the cooking will be stopped in the middle, so that delicious rice cannot be cooked.

[0058] Therefore, when the locking mechanism 206 is in the locked state and the power is supplied, if the power supply to the external electrical device 21 is stopped when the locking mechanism 206 is switched to the unlocked state, when the first operation is performed in the locked state and the power is not supplied, the ECU 100 controls the locking mechanism 206 to be switched to the unlocked state. In addition, when the first operation is performed in the locked state and the power is supplied, the ECU 100 maintains the locked state of the locking mechanism 206.

[0059] Thus, when the first operation is performed in the locked state during non-power supply, the lock mechanism 206 is switched to the unlocked state, and the power supply to the external electrical device 21 is stopped. On the other hand, when the first operation is performed in the locked state during power supply, the locked state of the lock mechanism 206 is maintained, and thus the power supply to the external electrical device 21 is not stopped. As a result, it is possible to avoid an unexpected power supply stop during power supply to the external electrical device 21. First Embodiment

[0060] Figure 2 1 is a flowchart showing the flow of the connector unlocking process in the first embodiment. Figure 2 The connector unlocking process is called and executed by the CPU 101 of the ECU 100 from a higher-level process at a predetermined period. The CPU 101 determines whether power is being supplied ( S111 ).

[0061] When it is determined that the power supply is not in progress (No in S111), that is, when the power supply is not in progress, the CPU 101 determines whether the connector unlocking condition when the power supply is not in progress is satisfied (S112). The connector unlocking condition when the power supply is not in progress may be, for example, a condition that an unlocking operation of a door of the vehicle 200 (for example, an operation of an unlocking button of the door) is performed. The connector unlocking condition when the power supply is not in progress may be, for example, a condition that an unlocking operation of a connector in the terminal device 800 is performed.

[0062] When determining that the connector unlock condition during non-power supply is not satisfied (NO in S112 ), CPU 101 returns the process to be executed to the upper-level process of the call source of the connector unlock process.

[0063] When it is determined that power is being supplied (yes in S111), CPU 101 determines whether the connector unlocking condition during power supply is satisfied (S113). The connector unlocking condition during power supply is a condition that is difficult to switch to an unlocked state unexpected by the user, compared with the connector unlocking condition during non-power supply, for example. The connector unlocking condition during power supply may also be a condition different from the connector unlocking condition during non-power supply, for example, a condition that the unlocking operation of the vehicle door has been performed a predetermined number of times (for example, 3 times or more). The connector unlocking condition during power supply may also be a condition that is the same as the connector unlocking condition during non-power supply, for example, a condition that the unlocking operation of the connector in the terminal device 800 has been performed.

[0064] When determining that the connector unlock condition during power supply is not satisfied (NO in S113 ), CPU 101 returns the process to be executed to the upper-level process of the call source of the connector unlock process.

[0065] When determining that the connector unlock condition is satisfied during power supply (YES in S113 ), CPU 101 outputs a control signal for controlling power conversion device 204 from interface 103 to stop power supply ( S117 ).

[0066] After S117, or when it is determined that the connector unlocking condition is satisfied when no power is supplied (Yes in S112), CPU 101 controls locking mechanism 206 to switch AC power supply connector 19 to the unlocked state (S118). Thereafter, CPU 101 returns the processing to be executed to the upper processing of the calling source of the connector unlocking processing. Second Embodiment

[0067] In the first embodiment, when the connector unlocking condition during power supply is not satisfied, no operation is performed. In the second embodiment, when the connector unlocking condition during power supply is not satisfied, a predetermined process is performed.

[0068] Figure 3 : is a flowchart showing the flow of the connector unlocking process in the second embodiment. Figure 3 The connector unlocking process is called and executed by the CPU 101 of the ECU 100 from the upper processing according to a predetermined cycle. Figure 3 In the connector unlocking process in the second embodiment of the present invention, Figure 2 The same processes as the connector unlocking process of the first embodiment are denoted by the same step numbers. In the second embodiment, the parts different from the first embodiment will be described.

[0069] When it is determined that the connector unlocking condition during power supply is not satisfied (No in S113), CPU 101 determines whether the connector unlocking condition during non-power supply is satisfied (S114). When it is determined that the connector unlocking condition during non-power supply is satisfied (Yes in S114), CPU 101 controls the display of output unit 840 to display a notification screen for notifying the user that the connector unlocking condition during power supply is not satisfied but the connector unlocking condition during non-power supply is satisfied during power supply (S115).

[0070] Figure 4 An example of a notification screen for notifying that the connector unlocking condition during power supply is not satisfied, but the connector unlocking condition during non-power supply is satisfied is shown. The notification screen is displayed on the touch panel display 870 by executing a power supply application (hereinafter referred to as "application") in the terminal device 800. The touch panel display 870 is composed of the touch panel of the input unit 830 and the display of the output unit 840 of the terminal device 800.

[0071] In this notification screen, the statement "A connector unlocking operation when not powering is detected during powering" is included to indicate that the connector unlocking condition during powering is not met, but the connector unlocking condition when not powering is met, a statement to indicate that the unlocking operation is not accepted, and a statement to indicate that an operation is required to switch to the unlocked state.

[0072] return Figure 3 When CPU 101 determines that the connector unlocking condition when no power is supplied is not satisfied (No in S114 ), or after S115 , CPU 101 returns the process to be executed to the upper process of the calling source of the connector unlocking process. Third Embodiment

[0073] In the second embodiment, when the connector unlocking condition during power supply is not satisfied but the connector unlocking condition during non-power supply is satisfied, the user is notified of this. In the third embodiment, this is notified and an operation to confirm the user's intention to switch to the unlocked state is accepted.

[0074] Figure 5 : is a flowchart showing the flow of the connector unlocking process in the third embodiment. Figure 5 The connector unlocking process is called and executed by the CPU 101 of the ECU 100 from the upper processing according to a predetermined cycle. Figure 5 In the connector unlocking process in the third embodiment of Figure 3The same processes as the connector unlocking process in the second embodiment are denoted by the same step numbers. In the third embodiment, the parts different from the second embodiment will be described.

[0075] When it is determined that the connector unlocking condition during non-power supply is satisfied (Yes in S114), CPU 101 notifies the user that the connector unlocking condition during power supply is not satisfied, but the connector unlocking condition during non-power supply is satisfied. In addition, CPU 101 controls the display of output unit 840 to display a notification screen for accepting an operation of confirming the user's intention to switch to the unlocked state (S115A).

[0076] Figure 6 An example of a notification screen for notifying that the connector unlocking condition is not satisfied during power supply but is satisfied during non-power supply and accepting an operation of the user confirming the intention to switch to the unlocked state. The notification screen is displayed on the touch panel display 870 of the terminal device 800.

[0077] In this notification screen, as an indication that the connector unlocking condition during power supply is not met but the connector unlocking condition during non-power supply is met, it includes a statement "A connector unlocking operation during non-power supply was detected during power supply." and a "Yes" button and a "No" button for accepting and confirming the user's intention to switch the connector to an unlocked state.

[0078] return Figure 5 After S115A, CPU 101 determines whether the unlock operation in the notification screen has been accepted (S116). If it is determined that the unlock operation has been accepted (Yes in S116), that is, Figure 6 When the “Yes” button is operated in the notification screen, CPU 101 executes the processing after S117 described in the first embodiment.

[0079] On the other hand, if it is determined that the unlocking operation is not accepted (No in S116), that is, Figure 6 If the "No" button is operated in the notification screen, CPU 101 returns the process to be executed to the upper-level process of the call source of the connector unlock process.

[0080] Modifications

[0081] (1) In the aforementioned embodiment, Figure 4 and Figure 6 The notification screen shown is displayed on the touch panel display 870 of the terminal device 800. However, this is not limited to this. Figure 4 and Figure 6The confirmation screen shown may also be displayed by another device, for example, HMI 130 of vehicle 200 .

[0082] (2) In the aforementioned implementation mode, if Figure 2 , Figure 3 as well as Figure 5 As shown, when the connector unlocking condition when power is not supplied is satisfied, the connector is unlocked in S118. However, the present invention is not limited thereto, and when power is not supplied, the connector may be unlocked not only when the connector unlocking condition when power is not supplied but also when the connector unlocking condition during power supply is satisfied.

[0083] (3) The above-described embodiments can be understood as disclosure of a control device such as the ECU 100 for the vehicle 200 or the locking mechanism 206 , and can be understood as disclosure of both the vehicle 200 or the locking mechanism 206 and a control method or a control program executed by the control device such as the ECU 100 .

[0084] Summarize

[0085] (1) If Figure 1 As shown, ECU 100 is a control device for a locking mechanism 206 that fixes a connector such as the AC power supply connector 19 to an inlet 202 of a vehicle 200. Figure 1 As shown, the connector includes an AC power supply connector 19 for supplying power to an electrical device 21 outside the vehicle 200. Figure 2 , Figure 3 as well as Figure 5 As shown, when the lock mechanism 206 is in the locked state and power is being supplied, if the lock mechanism 206 is controlled to be switched to the unlocked state, power supply to the external electrical device 21 is stopped (for example, S117). Figure 2 , Figure 3 as well as Figure 5 As shown, when the first operation is performed in the locked state during non-power supply (for example, an operation in which the connector unlocking condition is satisfied during non-power supply), the ECU 100 controls the locking mechanism 206 to be switched to the unlocked state (for example, if it is determined to be yes in S112, S118 is executed). When the first operation is performed in the locked state during power supply, the locked state of the locking device is maintained.

[0086] Thus, when the first operation is performed in the locked state during non-power supply, the locking mechanism 206 is switched to the unlocked state, and the power supply to the external electrical device 21 is stopped. On the other hand, when the first operation is performed in the locked state during power supply, the locked state of the locking mechanism 206 is maintained, and thus the power supply to the external electrical device 21 is not stopped. As a result, it is possible to avoid an unexpected stop of power supply to the external electrical device 21 during power supply.

[0087] (2) If Figure 2 , Figure 3 as well as Figure 5 As shown, when a second operation different from the first operation is performed during power supply in the locked state (for example, an operation in which a connector unlocking condition is satisfied during power supply), the ECU 100 may control the lock mechanism 206 to be switched to the unlocked state (for example, if it is determined to be yes in S113, S118 is executed). Thus, when a second operation different from the first operation is performed, even during power supply, it can be determined that the user intends to stop power supply and switch the lock mechanism 206 to the unlocked state, thereby switching to the unlocked state.

[0088] (3) If Figure 2 , Figure 3 as well as Figure 5 As shown, when the first operation (e.g., door unlocking operation) is performed multiple times (e.g., 3 times) in the locked state while power is supplied, the ECU 100 may control the locking mechanism 206 to be switched to the unlocked state (e.g., if it is determined to be yes in S113, S118 is executed). Thus, when the first operation for switching to the unlocked state is performed multiple times in the non-powered state, even in the power supply, it can be determined that the user intends to stop the power supply and switch the locking mechanism 206 to the unlocked state, thereby switching to the unlocked state.

[0089] (4) If Figures 3 to 6 As shown, when the first operation is performed during power supply in the locked state, the ECU 100 may perform processing for notifying the operation required to switch the lock mechanism 206 to the unlocked state (for example, displaying Figure 4 The processing of the notification screen, Figure 6 (a process of displaying a button for accepting the user's intention on a notification screen of FIG. 1 ). Thus, the user can be informed of the operation required to switch to the unlocked state during power supply.

[0090] (5) When the second operation is performed in the locked state and the power is not supplied, the control device may control the lock mechanism 206 to be switched to the unlocked state. Thus, when the second operation is performed, the lock mechanism 206 can be switched to the unlocked state not only in the power supply but also in the power supply is not supplied.
