Description

  The present invention relates to a vehicle, and more particularly, to a vehicle including a connection portion that connects a connector of a power cable that supplies electric power to the vehicle from outside the vehicle.

  Japanese Patent Laying-Open No. 2009-065728 (Patent Document 1) discloses a vehicle including a connection portion that connects a connector of a power cable that supplies power to the vehicle from the outside of the vehicle. In this vehicle, when the charging cable is connected to the vehicle in order to prevent the vehicle from traveling while the charging cable is connected to the vehicle, the vehicle is controlled so as not to travel, while the lid ( When the charging lid is locked in the closed state, the vehicle is controlled to be in a travelable state.

JP 2009-065728 A

  In the vehicle disclosed in the above document, when the charging lid is locked in the closed state, the connection of the charging connector by the user can be prevented, but when the charging lid is open, the user connects the charging connector to the connecting portion of the vehicle. It is possible to connect to.

  Therefore, in order to more reliably prevent the vehicle from traveling with the charging cable connected to the vehicle, the user can connect the charging connector even when the charging lid is open when the vehicle can travel. It is advisable to take measures to avoid mounting.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a vehicle with improved certainty for preventing dragging of the charging cable.

  In summary, the present invention is a vehicle capable of charging an on-vehicle power storage device from the outside, and an operation unit for performing an operation of transitioning between a state where the vehicle cannot travel and a state where traveling is possible, A connection portion for connecting a connector of a power cable for supplying power to the vehicle from the outside of the vehicle, a first state that prevents the connector from being attached to the connection portion, and a second state that enables the connector to be attached to the connection portion Includes a mechanism that can be changed, and a control unit that controls the mechanism. When the control prohibition condition is satisfied including that the operation unit is operated so as to change the vehicle state from a state where the vehicle cannot travel to a state where the vehicle can travel and a connector is not attached to the connection unit The mechanism is changed from the second state to the first state.

  According to said structure, since a mechanism changes a mechanism to the 1st state which prevents attachment of the connector to a connection part when attachment prohibition conditions are satisfied, the situation where a vehicle runs by dragging a power cable is avoided. it can. The mechanism may be a lid that automatically opens and closes. The mechanism may be provided separately from the lid. Furthermore, the mechanism may be used also as a lock mechanism that locks the connector to the connection portion, or may be provided separately from the lock mechanism.

  Preferably, the vehicle further includes a lid that covers the connection portion. The installation prohibition condition is that the operation unit has been operated so as to change the vehicle state from being unable to travel to being able to travel, and that the connector is not attached to the connection part, and the lid is open. Including that. The control unit sets the mechanism to the second state when the lid is closed.

  With the above configuration, even when the operation unit is operated so as to change the state of the vehicle from a state where it cannot travel to a state where it can travel when the lid is closed, the mechanism remains unchanged in the second state. The number of times that the mechanism is operated can be reduced, and the number of times that an operation sound is generated due to the operation of the mechanism is reduced.

  Preferably, the mechanism is also used as a lock mechanism that locks the connector in a state in which the connector cannot be removed from the connection portion when the connector is attached to the connection portion. The locking mechanism is configured such that when the connector is not attached to the connection portion and the transition is made from the unlocked state to the locked state, the connector cannot be attached to the connection portion.

  With the above-described configuration, it is not necessary to provide a mechanism that prevents the connector from being attached to the connection portion separately from the lock mechanism, which is advantageous in terms of installation space and cost.

  Preferably, the control unit sets the mechanism to the second state when the operation unit is operated so as to change the vehicle state from the runnable state to the unrunnable state and the connector is not attached to the connection unit. To do.

  According to said structure, since it becomes possible to attach a connector to a connection part when it is a state which cannot drive | work a vehicle, it can attach a connector and can supply electric power to a vehicle via a power cable from the outside.

  According to the present invention, the installation prohibition condition is satisfied, including that the operation unit is operated so as to change the vehicle state from the state where the vehicle cannot travel to the state where the vehicle can travel, and that the connector is not attached to the connection unit. Since a mechanism that sometimes prevents the connector from being attached is provided, it is possible to reliably prevent the vehicle from dragging the power cable and traveling.

  Embodiments of the present invention will be described below with reference to the drawings. In the following embodiments, the same or corresponding parts are denoted by the same reference numerals, and description thereof will not be repeated.

  FIG. 1 is a block diagram of a vehicle and a charging cable unit according to an embodiment of the present invention. The vehicle may be any of an electric vehicle, a hybrid vehicle, and a fuel cell vehicle as long as the vehicle is equipped with a chargeable power storage device (battery).

  Referring to FIG. 1, vehicle 100 locks inlet 290, charger 240, control device 170, shift operation unit 174, vehicle activation switch 175, and charging connector 580 of charging cable unit 500 to inlet 290. Connector lock switch 177, connector lock mechanism 260, battery 150, drive unit 200, and drive wheel 210.

  Charging of the vehicle 100 is performed in a state where the vehicle cannot travel (a state where the vehicle is set to a parking range or a state where the vehicle traveling system is stopped (Ready-OFF state)). The user operates the operation unit such as the shift operation unit 174 (shift lever or the like) or the vehicle start switch 175 whose position is detected by the shift position sensor before charging, and sets the vehicle to the parking range or Ready-OFF. After the state is set, charging connector 580 is inserted into inlet 290 to start charging. During charging, the connector lock mechanism 260 locks the charging connector 580 so as not to be removed from the inlet 290.

  The charger 240 includes an AC / DC conversion circuit, a DC / AC conversion circuit, an insulating transformer, a rectifier circuit, and the like. Based on the drive signal from control device 170, charger 240 converts AC power received from inlet 290 into DC power, further converts DC power into high-frequency AC power, and uses an insulating transformer in accordance with the turn ratio. The voltage level is converted to DC power by a rectifier circuit.

  The charging cable unit 500 is for connecting the vehicle 100 and the power source 402. Charging cable unit 500 includes a charging connector 580, a plug 520, and a CCID (Charging Circuit Interrupt Device) 510.

  Charging connector 580 is connected to an inlet 290 provided in vehicle 100. For example, a charging cable connection detection circuit such as a switch is provided in charging connector 580. When the charging connector 580 is connected to the inlet 290, the switch is closed, and a connection signal CN indicating that the charging connector 580 is connected to the inlet 290 is input to the controller 170. By such a charging cable connection detection circuit, a state where the charging connector 580 is fitted to the inlet 290 (fitted state) is detected.

  Plug 520 is connected to an outlet 400 to which AC power is supplied from power source 402. The outlet 400 is provided, for example, in a charging station or a house.

  CCID 510 is inserted in the middle of the cable and includes a relay. When the relay is open, the path for supplying power from the power supply 402 outside the vehicle 100 to the vehicle 100 is blocked. When the relay is closed, power can be supplied from the power source 402 to the vehicle 100. By connecting charging connector 580 to inlet 290, the relay of CCID 510 is controlled by control device 170.

  In the present embodiment, electric power output from power supply 402 is supplied to battery 150 via charging cable unit 500, so that battery 150 is charged.

  Vehicle 100 further includes a charging lid 252 and a charging lid lock mechanism 295. The state of the charging lid 252 can be changed between a state where the inlet 290 is covered and the charging connector 580 cannot be connected (closed state) and a state where the charging connector 580 can be connected to the inlet 290 (open state). The charging lid lock mechanism 295 can be changed between a locked state in which the charging lid 252 is closed and a unlocked state in which the charging lid 252 can be opened.

  When the vehicle is ready to travel, it is conceivable that the charging lid 252 is locked in the closed state so that the charging connector 580 cannot be connected to the inlet 290. However, if the user forgets to close the charging lid 252 and leaves it in the open state, the charging connector 580 may be connected to the inlet 290 even when the vehicle is ready to travel. Therefore, it is desirable that the charging connector 580 cannot be connected even in such a case.

  The vehicle having such a configuration is provided with a connector lock mechanism 260 in order to prevent the charging cable unit 500 from being stolen. However, if the vehicle travels with the charging connector 580 locked to the inlet 290, the inlet 290 or the charging cable unit 500 may be damaged. Therefore, in the present embodiment, when the vehicle is ready to run, the connector lock mechanism 260 is unlocked. In the present embodiment, the connector lock mechanism 260 will be described later with reference to FIG. 4, but also functions as a mechanism that prevents the charging connector 580 from being attached when the connector locking mechanism 260 operates when the charging connector 580 is not connected.

  FIG. 2 is a diagram illustrating a configuration of an inlet accommodating portion that accommodates an inlet of a vehicle including a connector lock mechanism. Referring to FIG. 2, the inlet accommodating portion 254 is usually covered with a charging lid 252 so that it cannot be seen from the outside. The inlet accommodating portion 254 accommodates the inlet 290, the connector lock switch 177 that locks the charging cable, the main body portion 262 of the connector locking mechanism 260, and the lock pin 261 inside the charging lid 252. In FIG. 2, a push button type switch is exemplified as the connector lock switch 177, but a non-contact type switch such as a proximity switch may be used.

  Further, the connector lock switch 177 for locking the charging connector is often operated immediately after the charging connector is connected to the inlet, and thus is installed in the vicinity of the inlet 290.

  FIG. 3 is a cross-sectional view of the charging connector and the inlet in a state where the charging connector is locked. With reference to FIGS. 2 and 3, in this modified example, in the locked state, the tip 316 </ b> A of the arm 316 is suppressed by the lock pin 261, and the arm 316 does not move even when the button 314 is pressed. Since the inlet 290 is provided with a projection, the connector cannot be removed from the inlet 290 unless the tip 316A of the arm moves upward. On the other hand, in the unlocked state, the lock pin 261 moves upward, so that the arm 316 can be moved.

  FIG. 4 is a diagram showing that the connector locking mechanism 260 also functions as a mechanism that prevents the charging connector 580 from being attached.

  Referring to FIG. 4, lock pin 261 of connector lock mechanism 260 is lowered before charging connector 580 is fitted into inlet 290. Then, even if the user tries to attach the charging connector 580 to the inlet 290, the tip 316A of the arm 316 comes into contact with the tip of the lock pin. Therefore, the charging connector 580 cannot be fitted into the inlet 290. That is, by lowering the lock pin 261 while the charging connector 580 is not connected, the connector locking mechanism 260 functions as a mechanism that prevents the charging connector 580 from being attached to the inlet 290.

  In the present embodiment, connector lock mechanism 260 is controlled to prevent attachment of charging connector 580 to inlet 290 when the vehicle is ready to travel. As an operation for setting the vehicle in a travelable state, an operation for releasing the parking range by a shift lever and an operation for setting the vehicle to a Ready-ON state by a start switch are conceivable. Hereinafter, the control related to the shift lever operation will be described with reference to FIGS. 5 to 7, and the control related to the start switch operation will be described with reference to FIGS.

  FIG. 5 is a flowchart for explaining a process for hindering the attachment of the connector accompanying the change of the shift position. The processing of this flowchart is called and executed from a predetermined main routine every predetermined time or every time a predetermined condition is satisfied.

  Referring to FIGS. 1 and 5, in step S <b> 11, control device 170 determines that the position (shift position) of shift operation unit 174 (shift lever, etc.) is changed from the parking (P) position to the other position according to the output of the shift position sensor. It is determined whether or not it has moved to the position. When the shift position moves from the parking (P) position to another position, the vehicle changes from a state where it cannot travel (P range) to a state where it can travel (D range, R range, etc.).

  If it is detected in step S11 that the shift position has moved from the P position to a position other than P, the process proceeds to step S12, and if not, the process proceeds to step S17. In step S17, control is returned to the main routine.

  In step S <b> 12, control device 170 determines whether or not charging lid 252 is in an open state based on signal CL indicating the opening / closing state of charging lid 252.

  If it is detected in step S12 that the charging lid 252 is in the open state, the process proceeds to step S13, and if not, the process proceeds to step S16.

  In step S16, the control device 170 causes the charging lid lock mechanism 295 to lock the charging lid 252 so that it does not open. As a result, the vehicle is in a state where the charging connector 580 cannot be connected to the inlet 290. When the locking process in step S16 ends, the process proceeds to step S17. In step S17, control is returned to the main routine.

  In step S <b> 13, control device 170 determines whether or not charging connector 580 is in a fitted state based on connection signal CN of charging connector 580. The charging connector 580 being in the fitted state indicates a state where the charging connector 580 is inserted into the inlet 290 to a position where electricity can be applied regardless of whether the connector locking mechanism 260 is locked.

  If it is determined in step S13 that charging connector 580 is in the fitted state, the process proceeds to step S14. In step S <b> 14, control device 170 controls connector locking mechanism 260 so as to unlock charging connector 580. Then, since the lock pin 261 is pulled upward by a motor (not shown), the charging connector 580 comes out of the inlet 290 when pulled.

  Therefore, even if the user forgets to remove the charging connector 580 from the inlet 290 and travels, the charging connector 580 is easily detached from the inlet 290 if the charging cable 507 is tensioned. Can reduce the situation.

  When the unlocking process in step S14 ends, the process proceeds to step S17. In step S17, control is returned to the main routine.

  On the other hand, if it is determined in step S13 that charging connector 580 is not in the fitted state, the process proceeds to step S15. In step S15, the control device 170 controls the connector lock mechanism 260 to a locked state (a state where the lock pin 261 is lowered). As described with reference to FIG. 4, when the connector locking mechanism 260 is set to the locked state when the charging connector 580 is not in the fitted state, the charging connector 580 is prevented from being attached to the inlet 290. Therefore, even when the user tries to connect charging connector 580 to inlet 290 when the vehicle is ready to travel, charging connector 580 is prevented from being inserted into inlet 290.

  FIG. 6 is a flowchart for explaining the process of unlocking the charging lid in the P range. The processing of this flowchart is called and executed from a predetermined main routine every predetermined time or every time a predetermined condition is satisfied.

  Referring to FIGS. 1 and 6, control device 170 determines in step S <b> 21 whether or not a user's charging lid opening operation has been detected. If the charging lid opening operation is not detected in step S21, the process proceeds to step S24. At this time, if the charging lid is locked, the control is returned to the main routine without being released as it is.

  If a charging lid opening operation is detected in step S21, the process proceeds to step S22. In step S22, control device 170 determines whether or not the shift range is the P range. If the shift range is not the P range in step S22, the process proceeds to step S24. At this time, if the charging lid is locked, the control is returned to the main routine without being unlocked.

  If it is determined in step S22 that the shift range is the P range, the parking gear is locked by the parking pole and the vehicle is in a state in which it cannot travel, so charging may be performed. Therefore, in this case, the process proceeds to step S23, and the charging lid lock mechanism 295 is controlled to be unlocked to release the lock. Then, when it is desired to connect the charging connector 580, the charging lid 252 can be opened. When the unlocking process ends in step S23, the control is returned to the main routine.

  By performing the control shown in FIG. 6, the lock of the charging lid is not released when the vehicle is in a travelable state, so that the user does not open it even if he tries to open the charging lid. Therefore, since a charging cable cannot be attached, it is prevented that the charging cable is dragged and traveled.

  FIG. 7 is a flowchart for explaining a process for permitting the attachment of the connector accompanying the change of the shift position. The processing of this flowchart is called and executed from a predetermined main routine every predetermined time or every time a predetermined condition is satisfied.

  Referring to FIGS. 1 and 7, control device 170 determines in step S31 whether or not the shift position has moved from a position other than the P position to the P position based on the output of the shift position sensor. When the shift position moves from a position other than the P position to the P position, the vehicle changes from a state where it can travel (D range, R range, etc.) to a state where it cannot travel (P range).

  If it is detected in step S31 that the shift position has moved from the P position to a position other than P, the process proceeds to step S32; otherwise, the process proceeds to step S36. In step S36, control is returned to the main routine.

  In step S <b> 32, control device 170 determines whether or not charging lid 252 is in an open state based on signal CL indicating the opening / closing state of charging lid 252.

  If it is detected in step S32 that the charging lid 252 is in the open state, the process proceeds to step S33, and if not, the process proceeds to step S36. In step S36, control is returned to the main routine.

  In step S <b> 33, control device 170 determines whether or not charging connector 580 is in a fitted state based on connection signal CN of charging connector 580.

  If it is determined in step S33 that the charging connector 580 is in the fitted state, the process proceeds to step S34. In step S34, control device 170 controls connector locking mechanism 260 to lock charging connector 580 in the connected state. Then, since the lock pin 261 is pulled down by a motor (not shown), the charging connector 580 cannot be removed from the inlet 290. Therefore, if the user operates the shift lever with the charging connector 580 connected to the inlet 290 to set the vehicle to the P range, the charging cable 507 is automatically locked and charging is performed. This saves you the trouble of locking.

  On the other hand, if it is determined in step S33 that charging connector 580 is not in the fitted state, the process proceeds to step S35. In step S35, the control device 170 controls the connector lock mechanism 260 to an unlocked state (a state where the lock pin 261 is raised). As described with reference to FIG. 4, when the connector locking mechanism 260 is set to the locked state when the charging connector 580 is not in the fitted state, the charging connector 580 is prevented from being attached to the inlet 290. Therefore, in step S35, the control device 170 raises the lock pin so that the charging connector 580 can be inserted into the inlet 290 and can be charged. When the unlock process in step S35 is completed, the process proceeds to step S36, and the control is returned to the main routine.

  The control according to the change of the shift position has been described above with reference to FIGS. Hereinafter, control according to a vehicle start operation (referred to as a Ready-ON operation) and a vehicle operation end operation (Ready-OFF operation) will be described.

  FIG. 8 is a flowchart for explaining processing that hinders the attachment of the connector accompanying the operation of the vehicle start switch. The processing of this flowchart is called and executed from a predetermined main routine every predetermined time or every time a predetermined condition is satisfied.

  Referring to FIGS. 1 and 8, control device 170 determines whether or not a start operation (Ready-ON operation) has been performed by vehicle start switch 175 in step S <b> 41. When the Ready-ON operation is performed, the vehicle changes from a state where the vehicle cannot travel (Ready-OFF state) to a state where the vehicle can travel (Ready-ON state).

  If a Ready-ON operation is detected in step S41, the process proceeds to step S42, and if not, the process proceeds to step S47. In step S47, control is returned to the main routine.

  In step S <b> 42, control device 170 determines whether or not charging lid 252 is in an open state based on signal CL indicating the opening / closing state of charging lid 252.

  If it is detected in step S42 that the charging lid 252 is in the open state, the process proceeds to step S43, and if not, the process proceeds to step S46.

  In step S46, the control device 170 causes the charging lid lock mechanism 295 to lock the charging lid 252 so that it does not open. As a result, the vehicle is in a state where the charging connector 580 cannot be connected to the inlet 290. When the lock process in step S46 is completed, the process proceeds to step S47. In step S47, control is returned to the main routine.

  In step S43, control device 170 determines whether or not charging connector 580 is in a fitted state based on connection signal CN of charging connector 580.

  If it is determined in step S43 that the charging connector 580 is in the fitted state, the process proceeds to step S44. In step S44, control device 170 controls connector locking mechanism 260 so as to unlock charging connector 580. Then, the lock pin 261 is pulled upward by a motor (not shown).

  When the unlock process in step S44 is completed, the process proceeds to step S47. In step S47, control is returned to the main routine.

  On the other hand, when it is determined in step S43 that the charging connector 580 is not in the fitted state, the process proceeds to step S45. In step S45, the control device 170 controls the connector lock mechanism 260 to a locked state (a state where the lock pin 261 is lowered). As described with reference to FIG. 4, when the connector locking mechanism 260 is set to the locked state when the charging connector 580 is not in the fitted state, the charging connector 580 is prevented from being attached to the inlet 290. Therefore, even when the user tries to connect charging connector 580 to inlet 290 when the vehicle is ready to travel, charging connector 580 is prevented from being inserted into inlet 290.

  FIG. 9 is a flowchart for explaining the process of unlocking the charging lid in the Ready-OFF state. The processing of this flowchart is called and executed from a predetermined main routine every predetermined time or every time a predetermined condition is satisfied.

  Referring to FIGS. 1 and 9, control device 170 determines in step S <b> 51 whether or not a user's charging lid opening operation has been detected. If the charging lid opening operation is not detected in step S51, the process proceeds to step S54. At this time, if the charging lid is locked, the control is returned to the main routine without being unlocked.

  If a charging lid opening operation is detected in step S51, the process proceeds to step S52. In step S52, control device 170 determines whether or not the vehicle is in a Ready-OFF state. If the vehicle is not in the Ready-OFF state in step S52, the process proceeds to step S54. At this time, if the charging lid is locked, the control is returned to the main routine without being released as it is.

  If it is determined in step S52 that the vehicle is in the Ready-OFF state, the drive unit 200 of the vehicle is disconnected from the battery 150 and cannot travel, so charging may be performed. Therefore, in this case, the process proceeds to step S53, and the charging lid lock mechanism 295 is controlled to the unlocked state to release the lock. Then, when it is desired to connect the charging connector 580, the charging lid 252 can be opened. When the unlocking process is completed in step S53, the control is returned to the main routine.

  By performing the control shown in FIG. 9, the lock of the charging lid is not released when the vehicle is in a travelable state. Therefore, since a charging cable cannot be attached, it is prevented that the charging cable is dragged and traveled.

  FIG. 10 is a flowchart for explaining processing for permitting attachment of a connector in accordance with operation of the vehicle start switch. The processing of this flowchart is called and executed from a predetermined main routine every predetermined time or every time a predetermined condition is satisfied.

  Referring to FIGS. 1 and 10, control device 170 determines whether or not a stop operation (Ready-OFF operation) has been performed by vehicle start switch 175 in step S <b> 61. When the Ready-OFF operation is performed, the vehicle changes from a state where it can travel (Ready-ON state) to a state where it cannot travel (Ready-OFF state).

  If a Ready-OFF operation is detected in step S61, the process proceeds to step S62, and if not, the process proceeds to step S66. In step S66, control is returned to the main routine.

  In step S62, control device 170 determines whether or not charging lid 252 is in an open state based on signal CL indicating the opening and closing state of charging lid 252.

  If it is detected in step S62 that the charging lid 252 is in the open state, the process proceeds to step S63, and if not, the process proceeds to step S66. In step S66, control is returned to the main routine.

  In step S <b> 63, control device 170 determines whether or not charging connector 580 is in a fitted state based on connection signal CN of charging connector 580.

  If it is determined in step S63 that charging connector 580 is in the fitted state, the process proceeds to step S64. In step S64, control device 170 controls connector locking mechanism 260 to lock charging connector 580 in the connected state. Then, since the lock pin 261 is pulled down by a motor (not shown), the charging connector 580 cannot be removed from the inlet 290. Therefore, if the user operates the shift lever with the charging connector 580 connected to the inlet 290 to set the vehicle to the P range, the charging cable 507 is automatically locked and charging is performed. This saves you the trouble of locking.

  On the other hand, when it is determined in step S63 that charging connector 580 is not in the fitted state, the process proceeds to step S65. In step S65, the control device 170 controls the connector lock mechanism 260 to an unlocked state (a state where the lock pin 261 is raised). As described with reference to FIG. 4, when the connector locking mechanism 260 is set to the locked state when the charging connector 580 is not in the fitted state, the charging connector 580 is prevented from being attached to the inlet 290. Therefore, in step S65, the control device 170 raises the lock pin so that the charging connector 580 can be inserted into the inlet 290 and can be charged. When the unlock process in step S65 is completed, the process proceeds to step S66, and control is returned to the main routine.

  The present embodiment will be summarized with reference to FIG. 1 again at the end. Vehicle 100 according to the present embodiment is configured to be able to charge vehicle-mounted battery 150 from the outside. The vehicle 100 supplies power to the vehicle from the vehicle start switch 175 or the shift operation unit 174 that is an operation unit for performing an operation of changing between a state where the vehicle cannot travel and a state where the vehicle can travel. The state is changed to an inlet 290 that connects the charging connector 580 of the power cable to be connected, a first state that prevents the charging connector 580 from being attached to the inlet 290, and a second state that allows the charging connector 580 to be attached to the inlet 290 And a control device 170 that controls the mechanism. The control device 170 has an attachment prohibition condition including that the operation unit is operated so as to change the vehicle state from a state where the vehicle cannot travel to a state where the vehicle can travel and that the charging connector 580 is not attached to the inlet 290. If established, the mechanism is changed from the second state to the first state.

  According to the above configuration, the control device 170 changes the mechanism to the first state that prevents the charging connector 580 from being attached to the inlet 290 when the installation prohibition condition is satisfied, so that the situation where the vehicle travels by dragging the power cable is avoided. Can be avoided. The mechanism may be a charging lid 252 configured to automatically open and close. Further, this mechanism may be provided separately from the charging lid 252. Further, this mechanism may be used also as a connector locking mechanism 260 that locks the charging connector 580 to the inlet 290 or may be provided separately from the connector locking mechanism 260.

  Preferably, vehicle 100 further includes a charging lid 252 that covers inlet 290. The attachment prohibition conditions include that the operation unit is operated so as to change the state of the vehicle 100 from a state where the vehicle 100 cannot travel to a state where traveling is possible, and that the charging connector 580 is not attached to the inlet 290, Including that 252 is open. Control device 170 sets the mechanism to the second state when charging lid 252 is closed.

  With the above configuration, even when the operation unit is operated to change the state of the vehicle from the state where the vehicle cannot travel to the state where the vehicle can travel when the charging lid 252 is closed, the mechanism remains in the second state. Therefore, the number of times that the mechanism is operated can be reduced, and the number of times that the operation sound of the motor or the like is generated due to the operation of the mechanism is reduced, and there is an effect that the user does not use extra nerves. In addition, the life of the mechanism including the motor can be extended. If the operation noise does not cause a problem, the charging lid state confirmation and the locking process indicated by the broken lines in FIGS. 5, 7, 8, and 10 are not necessarily performed.

  Preferably, the mechanism is also used as connector locking mechanism 260 that locks charging connector 580 in a state in which charging connector 580 cannot be removed from inlet 290 when charging connector 580 is attached to inlet 290. When the connector lock mechanism 260 transitions from the unlocked state (corresponding to the second state) to the locked state (corresponding to the first state) in a state where the charging connector 580 is not attached to the inlet 290, the charging connector 580 is connected to the inlet 290. It is comprised so that it cannot become attached.

  With the above configuration, it is not necessary to provide a mechanism for preventing the charging connector 580 from being attached to the inlet 290 separately from the connector lock mechanism 260, which is advantageous in terms of installation space and cost.

  Preferably, control device 170 operates the second mechanism when the operation unit is operated so as to change the vehicle state from a state where traveling is possible to a state where traveling is not possible, and charging connector 580 is not attached to inlet 290. Set to state.

  According to the above configuration, since the charging connector 580 can be attached to the inlet 290 when the vehicle cannot travel, the charging connector 580 is attached and power is supplied to the vehicle from the outside via the power cable. Can do.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
