An electronic key device includes: a communication device; and a processor including hardware, the processor being configured to determine whether the electronic key device is in a predetermined state, excluding a stationary state and a state where the electronic key device is positioned far away from a vehicle by a predetermined distance or more, disable execution of a function of locking or unlocking the vehicle through information communication with the vehicle via the communication device when the electronic key device is in the predetermined state, and enable execution of the function when the electronic key device is not in the predetermined state.

A mobile device is carried by a person to be authenticated. An acceleration sensor is installed in the mobile device and configured to output an acceleration signal corresponding to acceleration applied to the mobile device. A processing device is configured to execute determination processing for determining whether the person is walking based on the acceleration signal. A control device is configured to control transmission of a radio signal, and to control an operation of a controlled device based on a result of the determination processing and a result of authentication processing for authenticating, by way of the mobile device, the person as a user of the controlled device. The determination processing is activated in response to reception of the radio signal by the mobile device.

A control device is configured to control operation of a controlled device based on a result of the determination processing and a result of processing for authenticating, by way of the mobile device, the person as a user of the controlled device. The control of the controlled device based on the authentication processing is disabled from time when the determination processing is initiated by the processing device until when a determination as to whether the person is walking is initially made.

A vehicle control device includes: an on-vehicle-user-number recognizing unit that performs recognition of an on-vehicle-user-number, and stores the on-vehicle-user-number in a storage unit, the on-vehicle-user-number being a number of users who have got on a vehicle; an off-vehicle-user-number recognizing unit that recognizes an off-vehicle-user-number, the off-vehicle-user-number being a number of the users who have got off the vehicle after the recognition of the on-vehicle-user-number by the on-vehicle-user-number recognizing unit; and a power door control unit that causes at least one power door to perform closing operation when the on-vehicle-user-number stored in the storage unit equals the off-vehicle-user-number recognized by the off-vehicle-user-number recognizing unit, the at least one power door being a power door that the user has used at a time of getting off the vehicle.

A vehicle control device includes: an unregistered-user-face-image acquiring unit that acquires an unregistered-user-face-image when an unregistered-user-getting-on recognizing unit recognizes that an unregistered user gets on the vehicle, the unregistered-user-face-image being a face image of the unregistered user; and a vehicle entry control unit that sets vehicle to a first entry-enabled-state when a matching degree between a user-candidate-face-image and the unregistered-user-face-image is equal to or higher than a first determination level, after the unregistered-user-getting-on recognizing unit recognizes that the unregistered user gets on the vehicle until a predetermined time elapses, the user-candidate-face-image being acquired by a user-candidate-face-image acquiring unit.

A vehicle control device includes: a power-supply control unit that sets a power supply to an off state when either a first power-off condition in which a user performs a power-off operation or a second power-off condition in which a first predetermined time elapses from the time when the user U gets off the vehicle with the power supply in an on state is satisfied; and a power-on-condition setting unit that: sets a power-on condition to a first power-on condition, when the power supply is set to the off state because the first power off condition is satisfied; and sets the power-on condition to a second power-on condition that is different from the first power-on condition, when the power supply is set to the off state because the second power off condition is satisfied.

An independent add-on automated vehicle lift gate system utilizing existing key fob authentication circuits in combination with an independent voice control system. The system uses microphones in connection with audio acquisition hardware and voice recognition hardware that actively listen for one or more voiced commands from a user outside of a vehicle. Before activating the mechanical system, which is for example the actuator of the lift gate and lock mechanism for the lift gate, the system will wait for confirmation from a separate vehicle system that monitors and notifies the vehicle lift gate system when an identification code is received from a key fob transponder located in a predetermined proximity of the vehicle, thereby authenticating the one or more voiced commands detected by the microphones.

An authentication pattern generation unit, if a signal from a portable device is received, prompts a user who uses the portable device to perform a specific action. A checking unit determines whether or not the user has performed the specific action. If the checking unit determines that the user has performed the specific action, the checking unit authenticates that the portable device is an authorized device.

A biometric information authenticating device includes a control unit to perform authentication by comparing biometric information read from an operator to pre-registered biometric information of a registered person, and to prohibit to give an instruction to execute an assigned function thereto when the number of authentication failures exceeds a predetermined number.

An authentication device includes a last session information storage portion that stores data of a first registered person successfully authenticated in the last session, an input unit to which information of a second registered person successfully authenticated by another authentication device is input, an information acquisition unit that acquires identification information of a user via an information sensor, a registered person information storage portion that stores registered person information in which a plurality of registered persons including the first and second registered persons are associated with their registration identification information, an authentication order information storage portion that stores information about an authentication order of the registered persons, and an authentication unit that authenticates the user by comparing the identification information acquired from the information acquisition unit with the registration identification information stored in the registered person information storage portion according to the stored authentication order.
