LOCK DEVICE
First Claim
1. A lock device for a power plug connected to and disconnected from an inlet arranged in a vehicle, wherein the vehicle includes a near field wireless communication system that permits control of the vehicle upon determination that near field wireless communication has been established when transmitting drive radio waves and receiving a response signal from an electronic key that uses the radio waves as a power source, and the lock device operates in a connection-disconnection restriction state, which restricts connection and disconnection of the power plug to and from the inlet, and a connection-disconnection permissible state, which permits connection and disconnection of the power plug to and from the inlet, the lock device comprisinga control unit configured to control and switch the lock device between the connection-disconnection restriction state and the connection-disconnection permissible state, wherein the control unit is configured to permit switching of the lock device between the connection-disconnection restriction state and the connection-disconnection permissible state after the determination that near field wireless communication has been established by the near field wireless communication system.

Abstract
In transponder communication (near field wireless communication), an electronic key uses drive radio waves as a power source and thereby does not need to be supplied with power from a key battery. To establish transponder communication, the distance between the electronic key and the vehicle has to be shorter than that for smart communication. However, transponder communication can be performed to switch a plug lock device between a lock state and an unlock state when a smart system cannot perform smart communication that switches the lock device between different states.

10. A controller arranged in a vehicle including an inlet and a lock device for a power plug connected to and disconnected from the inlet, the controller comprising:
-
a first control unit that permits control of the vehicle upon determination that near field wireless communication has been established when transmitting drive radio waves and receiving a response signal from an electronic key that uses the radio waves as a power source; and a second control unit that controls the lock device to selectively restrict connection and disconnection of the power plug to and from the inlet, wherein the second control unit is configured to permit operation of the lock device when the first control unit determines that the near field wireless communication has been established.

11. A vehicle comprising:
-
an inlet for a power plug; a lock device arranged in the inlet, wherein the lock device restricts connection and disconnection of the power plug to and from the inlet; and a controller that controls the vehicle, wherein the controller includes a first control unit that permits control of the vehicle upon determination that near field wireless communication has been established when transmitting drive radio waves and receiving a response signal from an electronic key that uses the radio waves as a power source, and a second control unit that controls the lock device to selectively restrict connection and disconnection of the power plug to and from the inlet, wherein the second control unit is configured to permit operation of the lock device when the first control unit determines that near field wireless communication has been established.
