The method includes determining whether the vehicle is stopped and determining whether recognition of a connection of the charging connector to the vehicle is enabled. Additionally, the method includes determining whether a charging inlet door is open or closed, in response to determining that recognition of the connection of the charging connector to the vehicle is disenabled, and executing transition of the vehicle from a first state restricting generation of driving power to a second state permitting generation of driving power when the charging inlet door is closed. ## Claims ### Claim 1 A plug-in vehicle, comprising: a first controller configured to recognize whether a charging connector is connected to the vehicle; a second controller configured to recognize whether a charging inlet door is open or closed; and a third controller configured to determine whether the charging inlet door is open or closed through the second controller when the vehicle is stopped and recognition of a connection of the charging connector to the vehicle through the first controller is disenabled, and to execute transition of the vehicle from a first state restricting generation of driving power to a second state permitting generation of driving power, in response to determining that the charging inlet door is closed, wherein the recognition of the connection of the charging connector to the vehicle through the first controller is enabled further includes disenabling communication between the first controller and a fourth controller, wherein the fourth controller is configured to operate the first controller and to manage a battery charged with power transmitted through the charging connector, wherein the third controller is further configured to: determine whether a state of charge (SOC) of the battery is increased prior to transition of the vehicle to the second state; determine that charging of the battery was normally executed at least during the charging, when the SOC of the battery satisfies a designated increase reference; and execute transition of the vehicle from the first state to the second state, when the SOC of the battery satisfies the designated increase reference, wherein the third controller is configured to restrict transition of the vehicle from the first state to the second state in response to determining that the charging inlet door is open, wherein the third controller is configured to determine that the vehicle is stopped, in response to determining that a vehicle speed is zero or is equal to or less than a predetermined speed using a speed sensor, and wherein the first controller is an on-board charger (OBC), the second controller is a body control module (BCM), the third controller is a hybrid controller or an electric vehicle control unit, and the fourth controller is a battery management system (BMS). ### Claim 2 (depends on 1) The plug-in vehicle according to claim 1, further comprising a first sensor configured to: sense whether the charging inlet door is open or closed; and transmit a sensing result to the second controller, wherein the third controller is configured to receive the sensing result of the first sensor from the second controller. ### Claim 3 (depends on 1) The plug-in vehicle according to claim 1, wherein the third controller is configured to operate a fifth controller to output a feedback action request, when the SOC of the battery satisfies a designated increase reference, and execute transition of the vehicle to the second state, when operation corresponding to the feedback action request is sensed through a sixth controller. ### Claim 4 (depends on 1) The plug-in vehicle according to claim 1, wherein the vehicle is a plug-in hybrid electric vehicle (HEV) or electric vehicle (EV).
