  • Patent number: 9969354
    Abstract: A lid lock device includes a push lifter which pushes a lid, a lid lock switch which detects whether the lid is pushed, a lid sensor which detects whether the lid is open or closed. A lid lock unit locks the lid when the lid is closed. A verification unit verifies an identification code transmitted from an electronic key. Under a situation in which the verification result of the verification unit indicates that the identification code has been verified and the detection result of the lid sensor indicates that the lid is closed, a control unit activates the lid lock unit to switch the lid between a locked state and an unlocked state when the lid lock switch detects that the closed lid has been pushed.

  • Patent number: 9377764
    Abstract: A plug lock device includes a release switch arranged in a vehicle and a lock mechanism switched between a lock state and an unlock state. The lock mechanism restricts removal of a power plug from an inlet of the vehicle when in the lock state and permits removal of the power plug from the inlet when in the unlock state. The lock mechanism is switched from the lock state to the unlock state when the release switch is operated and wireless communication is established between the vehicle and an authentic electronic key. The lock mechanism is switched to the unlock state even though the wireless communication between the vehicle and the electronic key is not established when the release switch is operated as long as an ignition of the vehicle is activated and a particular switch arranged in the vehicle is operated.

  • Patent number: 9120452
    Abstract: A vehicle operation authorization system includes a server that receives identification information, which identifies a first portable electronic device that is used as an electronic key for a vehicle, from the first portable electronic device, verifies the identification information, and transmits an operation permission signal to the vehicle to permit a vehicle operation in accordance with a request from the first portable electronic device. A key registration unit registers an encryption key, which is provided from the server, to the first portable electronic device. An access authorization unit uses the encryption key, which is registered in the first portable electronic device, to grant access authorization for accessing the server to a second portable electronic device so that the second portable electronic device functions as the electronic key authorized to operate the vehicle.

  • Patent number: 9037313
    Abstract: A lid lock controller includes a lid lock unit operable in a lock state, which keeps the lid closed, and an unlock state, which allows for the lid to open. A detection unit detects an unlocking operation performed on the lid lock unit. A key check unit checks whether or not an electronic key is located in the vicinity of the vehicle through wireless communication between the vehicle and the electronic key when the unlock operation is detected. An unlocking unit switches the lid lock unit to the unlock state when the electronic key is located in the vicinity of the vehicle. The unlocking unit switches the lid lock unit to the unlock state even when the electronic key is not located in the vicinity of the vehicle as long as a further lid unlock condition is satisfied.

  • Patent number: 8753136
    Abstract: A power feeding plug locking device that locks a power feeding plug to a power feeding inlet. The power feeding inlet is arranged in a machine including a door that can be locked. The locking device includes a lock mechanism of which operational state is shifted between a lock state and an unlock state. The lock mechanism prohibits removal of the power feeding plug from the inlet in the lock state and allows removal of the power feeding plug from the inlet in the unlock state. An operation unit is operated when switching the operational state of the lock mechanism between the lock state and the unlock state. A door lock state confirmation unit confirms whether the door of the machine is locked. A controller controls the operational state of the lock mechanism based on the operation of operation unit whether the door is locked.

  • Patent number: 8678847
    Abstract: A power plug locking device arranged in a vehicle includes a lock member moved between a lock position, in which the lock member prohibits removal of a power plug from a vehicle inlet, and an unlock position, in which the lock member permits removal of the power plug from the vehicle inlet. A drive source is activated to move the lock member from the lock position to the unlock position. An unlock switch is manually operated to move the lock member to the unlock position. An unlock circuit activates the drive source to move the lock member to the unlock position when the operation of the unlock switch and an unlock state of a vehicle door are both detected.

  • Patent number: 8523596
    Abstract: A power plug locking device used with a door lock drive source that locks a vehicle door includes a lock mechanism switched between a lock state, in which removal of a power plug from an inlet is prohibited, and an unlock state, in which the removal is permitted. A plug lock drive source performs an unlocking operation that switches the lock mechanism to the unlock state. A plug lock detector, which detects whether the lock mechanism is in the lock state, is connected between the plug lock drive source and an unlock terminal of the door lock drive source. A power supply circuit supplies the plug lock drive source with current and switches the lock mechanism to the unlock state when the door lock drive source is performing an unlocking operation while the plug lock detector is detecting that the lock mechanism is in the lock state.
