[Technical field]

[0001] The present disclosure relates to vehicles. [Background technology]

[0002] 2. Description of the Related Art Vehicles that can prevent situations such as theft of a charging cable used for charging and tampering with a vehicle-mounted outlet, such as the insertion of foreign objects, have been known.

[0003] When an occupant moves away from the vehicle, the vehicle described in Patent Document 1 switches the charging lock mechanism from an unlocked state to a locked state based on a command to switch the door lock mechanism from an unlocked state to a locked state. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2009-81917 A Summary of the Invention [Problem to be solved by the invention]

[0005] When the charging port of an electric vehicle is open and a charging cable is connected to the charging port to charge the electric vehicle, if the sliding door is open, there is a risk that the sliding door and the charging cable will interfere with each other. Patent Document 1 does not take into consideration measures to address this issue.

[0006] Such a problem is not limited to electric vehicles, but also occurs in vehicles that generate driving force using other energies such as gasoline or hydrogen. In such vehicles, there is also a risk of interference between the sliding door and the energy supply connector that is connected to the energy supply port.

[0007] Therefore, an object of the present disclosure is to provide an electric vehicle that can avoid interference between a sliding door and an energy supply connector during charging. [Means for solving the problem]

[0008] The vehicle of the present disclosure includes a sliding door, an energy storage device for storing energy used to generate driving force for the vehicle, an energy supply port located within the movable range of the sliding door for receiving energy provided from an external energy supply source and supplying the energy to the energy storage device, and a control device that limits the movement of the sliding door when an energy supply connector is connected to the energy supply port.

[0009] According to this configuration, when the energy supply connector is connected to the energy supply port, the movement of the sliding door is restricted, so that interference between the sliding door and the energy supply connector can be avoided.

[0010] Preferably, the control device inhibits the movement of the sliding door when the energy supply connector is connected to the energy supply port.

[0011] According to this configuration, when the energy supply connector is connected to the energy supply port, the movement of the sliding door is prohibited, so that interference between the sliding door and the energy supply connector can be avoided.

[0012] Preferably, the control device limits the movable range of the sliding door when the energy supply connector is connected to the energy supply port.

[0013] According to this configuration, when the energy supply connector is connected to the energy supply port, the range in which the sliding door can move is limited, thereby making it possible to avoid interference between the sliding door and the energy supply connector.

[0014] Preferably, the external energy supply source is an external power source, the energy storage unit is a power storage device, the energy supply port is a charging port, and the energy supply connector is a charging connector of a charging cable.

[0015] This makes it possible to prevent interference between the sliding door and the charging connector of the charging cable during charging. Effect of the Invention

[0016] According to the present disclosure, interference between the sliding door and the energy supply port during charging can be avoided. [Brief description of the drawings]

[0018] Hereinafter, the present embodiment will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are designated by the same reference characters and their description will not be repeated.

[0019] [First embodiment] Hereinafter, the present embodiment will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are designated by the same reference characters and their description will not be repeated.

[0020] [First embodiment] FIG. 1 is a diagram showing a schematic overall configuration of an electric vehicle 1 according to a first embodiment. The electric vehicle 1 is a vehicle capable of external charging, in which an on-board power storage device is charged using power supplied from a charging cable connected to an AC power source outside the vehicle. The electric vehicle 1 is, for example, an electric vehicle, a plug-in hybrid vehicle, or a fuel cell vehicle. In this embodiment, an example in which the electric vehicle 1 is an electric vehicle will be described. Note that, in this embodiment, an example in which power is supplied from an AC power source outside the vehicle during external charging of the electric vehicle 1 will be described, but the power source outside the vehicle is not limited to an AC power source. The power source outside the vehicle may be a DC power source.

[0021] The electric vehicle 1 includes an electricity storage device 10, a system main relay 35, a power control unit (hereinafter also referred to as a “PCU (Power Control Unit)”) 40, a power output device 50, drive wheels 60, and an ECU (Electronic Control Unit) 100.

[0022] The power storage device 10 is configured by stacking a plurality of batteries. The batteries are, for example, nickel-metal hydride, lithium ion, or other secondary batteries. The batteries may be batteries having a liquid electrolyte between the positive and negative electrodes, or may be batteries having a solid electrolyte (all-solid-state batteries).

[0023] The PCU 40 collectively represents a power conversion device for receiving electric power from the power storage device 10 and driving the power output device 50. For example, the PCU 40 includes an inverter for driving a motor included in the power output device 50, a converter for boosting the electric power output from the power storage device 10 and supplying the boosted electric power to the inverter.

[0024] Power output device 50 collectively refers to devices for driving drive wheels 60. For example, power output device 50 includes a motor that drives drive wheels 60. Furthermore, power output device 50 generates electricity during braking of the vehicle by operating the motor that drives drive wheels 60 in a regenerative mode, and outputs the generated electricity to PCU 40. Hereinafter, power output device 50 and drive wheels 60 will be collectively referred to as the "drive section."

[0025] One end of the system main relay 35 is electrically connected to the PCU 40, and the other end is electrically connected to the power storage device 10. The system main relay 35 is switched between an on and off state in accordance with a control signal from the ECU 100. When the system main relay 35 is in an off state, the supply of power from the power storage device 10 to the drive unit is cut off, and when the system main relay 35 is in an on state, the supply of power from the power storage device 10 to the drive unit is possible.

[0026] The ECU 100 includes a CPU (Central Processing Unit), a memory, and an input / output buffer, all of which are not shown, and receives input of signals from sensors and the like, outputs control signals to each device, and controls each device. Note that these controls are not limited to processing by software, and can also be performed by configuring and processing using dedicated hardware (electronic circuits).

[0027] Electrically powered vehicle 1 includes, as components for performing external charging, a charging relay 30, a charger 70, a vehicle inlet 90, power lines CPL, CNL, and a power line CL.

[0028] The vehicle inlet 90 is a charging port configured to be connectable to a charging connector 410 provided at the tip of a charging cable 400 of an external power source. The vehicle inlet 90 is covered by a charging lid 2 when the charging connector 410 of the charging cable 400 is not connected. When external charging of the electric vehicle 1 is performed, the charging lid 2 is opened and the charging connector 410 of the charging cable 400 is connected to the vehicle inlet 90.

[0029] Charger 70 is connected to vehicle inlet 90 via power line CL, and is connected to one end of charging relay 30 via power lines CPL, CNL. Charger 70 is operated by a control signal from ECU 100, and converts AC power received from charging connector 410 via vehicle inlet 90 into power that can be charged into power storage device 10, and supplies the power storage device 10. In this way, power storage device 10 is charged using the AC power supplied from charging connector 410.

[0030] The other end of charging relay 30 is electrically connected to power storage device 10. Charging relay 30 is switched between an on and off state in accordance with a control signal from ECU 100. Charging relay 30 is switched to the on state when external charging of power storage device 10 is performed.

[0031] The lid open / close sensor S1 is configured to detect the open / close state of the charging lid 2 (i.e., whether the charging lid 2 is open or closed). A known sensor can be used as the lid open / close sensor S1. Examples of the lid open / close sensor S1 include a limit switch, a proximity sensor, and a photoelectric sensor. The detection result by the lid open / close sensor S1 is output to the ECU 100.

[0032] The connector connection sensor S2 is configured to detect whether or not the charging connector 410 is connected to the vehicle inlet 90 of the electric vehicle 1. A known sensor can be used as the connector connection sensor S2. Examples of the connector connection sensor S2 include a limit switch, a proximity sensor, and a photoelectric sensor. The detection result by the connector connection sensor S2 is output to the ECU 100.

[0033] The sliding door 81 is configured to open and close an opening of the electric vehicle 1. In this embodiment, the sliding door 81 is an electric sliding door (power sliding door). The sliding door 81 can be opened and closed electrically.

[0034] The electric vehicle 1 includes a slide door drive control unit 91 for controlling the drive of the slide door 81. The slide door drive control unit 91 includes a door motor (door drive unit) 92 and a slide mechanism 93.

[0035] The door motor 92 drives the sliding door 81. The slide mechanism 93 slides the sliding door 81 in the front-rear direction by the driving force of the door motor 92.

[0036] 2 is a diagram showing sliding door 81, charging lid 2, and vehicle inlet 90. When sliding door 81 is moved to the position of charging lid 2 and vehicle inlet 90, if charging lid 2 is open and charging connector 410 of charging cable 400 is connected to vehicle inlet 90, there is a risk of interference between sliding door 81 and charging lid 2 and charging cable 400.

[0037] In the present embodiment, when the charging connector 410 is connected to the vehicle inlet 90, the ECU 10 prohibits the movement of the sliding door 81. More specifically, when the charging connector 410 is connected to the vehicle inlet 90, the ECU 10 does not cause the door motor 92 to drive the sliding door 81, and keeps the sliding door 81 in a fully closed state, even if an operation to open the sliding door 81 is performed.

[0038] FIG. 3 is a flowchart showing a control procedure for the sliding door 81 in the first embodiment.

[0039] In S101, the sliding door 81 is opened. In S102, when the lid open / close sensor S1 detects that the charging lid 2 is closed, the process proceeds to S103. When the lid open / close sensor S1 detects that the charging lid 2 is open, the process proceeds to S105.

[0040] In S103, when the connector connection sensor S2 detects that the charging connector 410 is not connected to the vehicle inlet 90 of the electric vehicle 1, the process proceeds to S104. When the connector connection sensor S2 detects that the charging connector 410 is connected to the vehicle inlet 90 of the electric vehicle 1, the process proceeds to S105.

[0041] In S104, the ECU 100 controls the door motor 92 to drive the sliding door 81 to fully open the sliding door 81.

[0042] In S105, the ECU 100 does not drive the sliding door 81 by the door motor 92, and keeps the sliding door 81 in the fully closed state.

[0043] [Second embodiment] FIG. 4 is a diagram showing a schematic overall configuration of an electric vehicle 1 according to the second embodiment.

[0044] The electric vehicle 1 includes a sliding door drive control unit 91A for controlling the drive of the sliding door 81. The sliding door drive control unit 91A includes a door motor (door drive unit) 92 and a slide mechanism 93, similar to the sliding door drive control unit 91 of the first embodiment. The sliding door drive control unit 91A further includes a position sensor 94.

[0045] The position sensor 94 detects the position of the sliding door 81. For example, the position sensor 94 detects the position of the sliding door 81 by counting the number of rotations of the door motor 92.

[0046] In this embodiment, when the charging connector 410 is connected to the vehicle inlet 90, the ECU 10 limits the range within which the sliding door 81 can be moved by the door motor 92. More specifically, when an operation to open the sliding door 81 is performed, the ECU 10 controls the door motor 92 in accordance with the output of the position sensor 94 to move the sliding door 81 to an intermediate position of the opening of the electric vehicle 1.

[0047] FIG. 5 is a flowchart showing a control procedure for the sliding door 81 in the second embodiment.

[0048] In S101, the sliding door 81 is opened. In S102, when the lid open / close sensor S1 detects that the charging lid 2 is closed, the process proceeds to S103. When the lid open / close sensor S1 detects that the charging lid 2 is open, the process proceeds to S105.

[0049] In S103, when the connector connection sensor S2 detects that the charging connector 410 is not connected to the vehicle inlet 90 of the electric vehicle 1, the process proceeds to S104. When the connector connection sensor S2 detects that the charging connector 410 is connected to the vehicle inlet 90 of the electric vehicle 1, the process proceeds to S105.

[0050] In S104, the ECU 100 controls the door motor 92 to drive the sliding door 81 to fully open the sliding door 81.

[0051] In S201, the ECU 100 controls the door motor 92 in accordance with the output of the position sensor 94 to move the sliding door 81 to the intermediate position of the opening of the electric vehicle 1.

[0052] [Third embodiment] In this embodiment, the sliding door 81 is a manual sliding door that can be manually opened and closed.

[0053] FIG. 6 is a diagram showing a schematic overall configuration of an electric vehicle 1 according to the third embodiment. The electric vehicle 1 includes a sliding door drive control unit 91B for controlling the driving of the sliding door 81. The sliding door drive control unit 91B includes a sliding mechanism 93, similar to the sliding door drive control unit 91 of the first embodiment. The sliding door drive control unit 91B further includes a door lock mechanism 98.

[0054] The door lock mechanism 98 includes a door lock actuator and a door lock link. The door lock actuator, which is made up of a gear and a motor, moves the door lock link up and down to lock or unlock the sliding door 81.

[0055] In the present embodiment, ECU 10 prohibits movement of sliding door 81 when charging connector 410 is connected to vehicle inlet 90. More specifically, when charging connector 410 is connected to vehicle inlet 90, ECU 10 causes door lock mechanism 98 to lock sliding door 81.

[0056] FIG. 7 is a flowchart showing a control procedure for the sliding door 81 in the third embodiment.

[0057] In S302, when the lid open / close sensor S1 detects that the charging lid 2 is closed, the process proceeds to S303. When the lid open / close sensor S1 detects that the charging lid 2 is open, the process proceeds to S305.

[0058] In S303, when the connector connection sensor S2 detects that the charging connector 410 is not connected to the vehicle inlet 90 of the electric vehicle 1, the process proceeds to S304. When the connector connection sensor S2 detects that the charging connector 410 is connected to the vehicle inlet 90 of the electric vehicle 1, the process proceeds to S305.

[0059] In S304, the ECU 100 does not cause the door lock mechanism 98 to lock the sliding door 81. As a result, the sliding door 81 moves in the opening direction in response to the user's operation.

[0060] In S305, the ECU 100 causes the door lock mechanism 98 to lock the sliding door 81. As a result, the sliding door 81 is locked and cannot move in the opening direction.

[0061] [Fourth embodiment] FIG. 8 is a diagram showing a schematic overall configuration of an electric vehicle 1 according to the fourth embodiment.

[0062] The electric vehicle 1 includes a sliding door drive control unit 91C for controlling the drive of the sliding door 81. The sliding door drive control unit 91C includes a sliding mechanism 93, similar to the sliding door drive control unit 91 of the first embodiment. The sliding door drive control unit 91C further includes a stopper mechanism 99.

[0063] The stopper mechanism 99 is provided on the sliding door 81 and includes a stopper lever configured to protrude to an intermediate position of the opening of the electric vehicle 1 under the control of the ECU 10, and an intermediate striker that is provided on the vehicle body and engages with the stopper lever protruding to the intermediate position.

[0064] In this embodiment, when the charging connector 410 is connected to the vehicle inlet 90, the ECU 10 limits the range within which the sliding door 81 can be moved by the door motor 92. More specifically, when an operation to open the sliding door 81 is performed, the ECU 10 controls the stopper mechanism 99 to stop the sliding door 81 at an intermediate position of the opening of the electric vehicle 1.

[0065] FIG. 9 is a flowchart showing a control procedure for the sliding door 81 in the fourth embodiment.

[0066] In S302, when the lid open / close sensor S1 detects that the charging lid 2 is closed, the process proceeds to S303. When the lid open / close sensor S1 detects that the charging lid 2 is open, the process proceeds to S305.

[0067] In S303, when the connector connection sensor S2 detects that the charging connector 410 is not connected to the vehicle inlet 90 of the electric vehicle 1, the process proceeds to S304. When the connector connection sensor S2 detects that the charging connector 410 is connected to the vehicle inlet 90 of the electric vehicle 1, the process proceeds to S405.

[0068] In S304, the ECU 100 does not cause the stopper mechanism 99 to execute the stop control of the sliding door 81. This allows the sliding door 81 to move in the opening direction in accordance with the user's operation, up to the fully open position.

[0069] In S405, the ECU 100 causes the stopper mechanism 99 to execute stop control of the sliding door 81. As a result, the sliding door 81 moves in the opening direction in accordance with the operation by the user, but the sliding door 81 stops at an intermediate position of the opening of the electric vehicle 1.
