That is, the controller 134, in response to receiving detection signals of detecting an obstacle which are output from the plurality of obstacle detectors, may acquire the reception order of the detection signals on the basis of the reception time at which the detection signal is received, may acquire the installation positions of the obstacle detectors having output the detection signals of the obstacle on the basis of the acquired reception order, may acquire a change in position of the user from the installation positions of the obstacle detectors corresponding to the reception order of the detection signals, may compare a movement path of the user corresponding to the acquired change in position of the user with a charging path stored in the storage 135, may determine whether a charging gun exists among objects in an image acquired by the image acquisition unit 170 when the acquired movement path of the user coincides with the charging path, may determine that the user has a charging intention in response to determining that the image of the charging gun exists and thus may control the driving unit 150 such that the charging cap 117a is automatically opened.
The controller 134 may acquire the distances of each of the plurality of obstacle detectors to the user on the basis of the detection signals detected by the plurality of obstacle detectors, and may acquire the movement path of the user on the basis of the installation position of an obstacle detector having output a detection signal associated with a distance among the acquired distances that is less than a predetermined distance.
The controller 134 may recognize a face among the objects in the image acquired by the image acquisition unit 170, determine whether the recognized face is the face of the user, and in response to determining that the recognized face is the face of the user, may determine that the user has a charging intention.
The controller 134 may identify a distance to an obstacle detected through the obstacle detector provided adjacent to the charging cap, and may recognize a charging gun in an image acquired through the image acquisition unit in response to the distance less than or equal to a predetermined distance, to thereby determine whether the user has a charging intention.
The configuration of the controller 134 for controlling the driving unit 150 to automatically open the charging cap 117a is identical to that of the previous embodiment, and thus detailed description thereof will be omitted.
Although the present embodiment has been described in relation to a vehicle that charges electricity as an energy source, the present disclosure may also be applied to a vehicle that replenishes a fuel as an energy source.

The controller 136 determines the charging intention of the user and controls the driving unit 150 to automatically open the charging cap 117a in response to determining that the user has a charging intention.
In the determining of the charging intention of the user, the controller 136 determines that the user has a charging intention in response to receiving a RF signal of the charging gun or the refueling gun through the communication device 161, and controls the driving unit 140 to automatically open the charging cap 117a.
The controller 136 may transmit an energy source replenishment command and energy source replenishment information through the communication device 161.
The configuration of the controller 136 for controlling the driving unit 150 to automatically open the charging cap 117a is identical to that of the previous embodiment, and thus description thereof is omitted.
In a case that the vehicle is provided with a cap input, the controller, in response to determining that the user has a charging intention, may determine whether a cap-opening signal is received from the cap input. The controller 136, in response to determining that the cap-opening signal is not received from the cap input, may control the driving unit 150 to automatically open the charging cap 117a, and in response to determining that the cap-opening signal is received, may not allow communication between the communication device and the charging gun.
In addition, the controller 136, in response to determining that the ignition of the vehicle is turned off, may supply power to the communication device and the driving unit for a preset period of time from the time when the ignition of the vehicle is turned off to determine the charging intention of the user.
The controller 136, in response to determining the user has alighted the vehicle, may determine whether a cap-opening signal is received from the cap input, and in response to determining that the cap opening signal is not received from the cap input, may determine the charging intention of the user on the basis of communication information of the communication device, and in response to determining that the cap opening signal is received from the cap input, may omit the determination of the charging intention of the user.
The controller 136, in response to determining that the vehicle is in a stationary state, may activate the communication acquisition unit to perform communication with the charging gun.
The storage 137 may store the identification information of the vehicle, the identification information of the charging gun, and the identification information of the refueling gun.
The vehicle determines whether the vehicle is in a stationary state, and in response to determining that the vehicle is in a stationary state, activates the operation of the communication device to determine whether a RF signal of the charging gun is received (331).
Here, the determining of whether the vehicle is in a stationary state may include determining whether the travel speed of the vehicle is zero.
The determining of whether the vehicle is in a stationary state may include determining whether the ignition of the vehicle is turned off.
The determining of whether the vehicle is in a stationary state may include determining whether the driver alights from the vehicle.
In addition, the vehicle, in response to determining that the ignition is turned off, may supply power to the driving unit and the communication device for a preset period of time from the time when the ignition of the vehicle is turned off to determine the charging intention of the user.
The vehicle may determine whether the vehicle is located at a charging station on the basis of current position information and map information, and in response to determining that the vehicle is located at the charging station, may control activation of the communication device. Then, the vehicle opens the charging cap in response to receiving a RF signal of the charging gun through the communication device (332).
The vehicle, in response to determining that an on-signal is received from the switch, may not perform the automatic opening by determining that the charging cap 117a is opened by the user.
The vehicle may determine whether the on-signal for opening the cap is received from the switch, which is a cap input, in a state in which the user alights from the vehicle, and in response to determining that the on-signal is not received from the switch, may perform communication with the charging gun to determine the charging intention of the user.
The vehicle, in response to determining that the on-signal is received from the switch in a state in which the user alights from the vehicle, may omit the determination of the charging intention of the user. That is, the vehicle may inactivate the communication operation of the communication device.
In the opening of the charging cap, the vehicle may change the charging cap from a locked state to an unlocked state, and allow the unlocked charging cap to be separated from the body such that the charging cap is opened.
In addition, when the charging cap is provided in a push-type, the vehicle may change the charging cap from the locked state to the unlocked state in response to determining that the user has a charging intention. In this case, the vehicle may allow the charging cap to be separated from the body in response to an external force applied to the charging cap by the user such that the charging cap is opened.
The vehicle identifies the charging state of the battery (333) to determine whether the charging is completed (334), and in response to determining that the charging is completed, automatically closes the charging cap (335).
In a case that an actuator for automatically closing the charging cap is not provided in the vehicle, the vehicle may determine whether the charging cap is open on the basis of the detection signal detected by the opening/closing detector 118 in response to determining that the charging of the battery is completed, and may output notification information notifying the user that the charging cap is open in response to determining that the charging cap is open such that the user recognizes the opening of the charging cap and closes the charging cap.
The outputting of the notification information for notifying the opening of the charging cap may include displaying the notification information for notifying the opening of the charging cap through the display in the form of an image, or outputting the notification information for notifying the opening of the charging cap through the sound output unit in the form of a guidance speech, a warning sound or a melody.
As described above, the present embodiment may determine the charging intention of the user and automatically open the charging cap, thereby removing a hassle to open the door and manipulate the switch when the user alights from the vehicle without turning on the switch for opening the charging cap.
Although the present embodiment has been described in relation to a vehicle chargeable at a charging station, the present disclosure may be applied to an internal combustion engine vehicle that travels on fuel. The internal combustion engine vehicle may include a fuel tank, and may include a refueling unit having a refueling port and a refueling cap.
The present embodiment has been described in relation to an example in which an energy source is replenished by a user or a refueling staff, but in a case that automatic charging or automatic refueling is performable according to autonomous driving, the vehicle may automatically open the cap in response to automatically recognizing a moving charging gun or refueling gun through image recognition and performing RF communication with the charging gun or the refueling gun.
