Abstract: A management server manages multiple digital keys for a vehicle. The management server determines, based on a type TY of the vehicle, whether to apply a prescribed condition RC to deletion of one of the digital keys when a request for deletion of that digital keys is obtained. The management server sets the digital key to an unusable state in accordance with a result of the determination.

Abstract: A management server manages multiple digital keys available for a vehicle. The multiple digital keys include a target digital key and one or more registration-involved digital keys that have been involved in registration of the target digital key. The multiple digital keys are respectively registered in multiple devices. The multiple devices include an involved device to which a predetermined one of the registration-involved digital keys is registered. The management server performs determining whether to apply a prescribed condition to deletion of the target digital key based on a user attribute of the involved device, and setting the target digital key to an unusable state in accordance with a result of the determination.

Abstract: A vehicle includes a wireless communication device and a proximity communication device. The vehicle receives a registration request for an owner key from a management server. The vehicle executes an activation process for the owner key via wireless communication using the wireless communication device in a case in which the received registration request includes information indicating that an owner device is a virtual device implemented on a server. The vehicle executes the activation process for the owner key via proximity communication using the proximity communication device in a case in which the received registration request does not include the information indicating that the owner device is the virtual device.

Abstract: A vehicle is configured to communicate with multiple devices that store information related to a digital key. The vehicle includes a locking means. The vehicle detects a locking request for the vehicle via communication with a requesting device. At this time, if the requesting device is located outside the vehicle (step S63: YES) and another device storing information related to the digital key of the vehicle is located inside the vehicle (step S62: YES), the vehicle checks the information of the other device (step S61) and determines whether to lock the vehicle based on the checked information of the other device (step S64).

Abstract: A management server manages multiple digital keys for a vehicle. The multiple digital keys include a target digital key, and digital keys that have been involved in registration of the target digital key. The management server determines whether to apply a prescribed condition RC to deletion of the target digital key based on a device type TY of an involved device to which predetermined one of digital keys involved in registration of the target digital key is registered. The management server sets the target digital key to an unusable state in accordance with a result of the determination.

Abstract: When receiving a deletion request specifying a registered shareable key, a management server executes a deletion process that deletes the shareable key of a target shareable device, which is specified in the received deletion request, and a shareable key that has been registered to a different shareable device based on a request from the target shareable device.

Abstract: An information processing device is configured to communicate with both a vehicle and a mobile information terminal in which a digital key for the vehicle is registered. The information processing device includes a processing circuit and a storage device. The storage device stores a database, in which a correction value for calibration of the ranging, performed by the vehicle to determine that the mobile information terminal is within an operating area of the digital key, is recorded in advance for each model of the mobile information terminal. The processing circuit is configured to execute acquiring of information identifying the model from the mobile information terminal, extracting of the correction value corresponding to the model of the mobile information terminal from the database, based on the information that is acquired, and transmitting of the correction value that is extracted to the vehicle.

Abstract: A management device manages a digital key. The digital key is registered in a mobile information terminal to operate a vehicle. This management device includes a processor configured to execute a process for issuing a password on a condition that an owner key that is a digital key registered in the mobile information terminal of a vehicle owner is deleted from the mobile information terminal, the password being needed to reregister the owner key.

Abstract: A vehicle configured to utilize a digital key registered in a mobile information terminal of a user, in which the vehicle includes a processor configured to transmit, to a management server for the digital key, log information of an event occurring in the vehicle when registering the digital key to the mobile information terminal.

Abstract: A casing has a housing section adapted to house an electronic key. The casing is formed of a material capable of blocking a particular frequency band. A controller is configured to cause an actuator to actuate a movable portion of the electronic key to transmit a signal for controlling a controlled device with the particular frequency band while switching a part of the casing into a state that the signal is allowed to pass, in a case where a transceiver receives a trigger signal from a mobile device.

Abstract: A car sharing system includes a car share device and a communication control unit. The car share device is configured to perform wireless communication with a mobile terminal that is operable as an electronic key. The communication control unit controls the wireless communication between the mobile terminal and the car share device so that an authentication process through bidirectional communication is executed only when a communication connection establishment process is performed. After the wireless communication has been established, the communication control unit controls the wireless communication so that actuation of an on-board device is permitted in accordance with operation of the mobile terminal through unidirectional communication from the mobile terminal to the car share device.

Abstract: The car sharing system includes a car share device and an encryption code updating unit. The car share device is configured to perform wireless communicate with a mobile terminal that is operable as a vehicle key. The encryption code updating unit updates a first encryption code, which was used during a previous connection of the mobile terminal and the car share device, to a second encryption code, which differs from the first encryption code, when the mobile terminal and the car share device are reconnected.

Abstract: A sharing system includes a sharing device arranged in a shared subject and a valet key that is allowed to operate the shared subject. The sharing system further includes a portable terminal that obtains key information required to use the shared subject and is allowed to operate the shared subject when the key information is authenticated through communication with the sharing device. The sharing system further includes a privilege granting unit that grants privilege to operate the shared subject from the portable terminal to the valet key, and a restriction imposing unit that imposes a restriction on use of the portable terminal when the operation privilege for the shared subject is granted from the portable terminal to the valet key.

Abstract: A car sharing system includes a car share device and a usage right lending unit that allows multiple users including a first user and a second user to use the vehicle. If the second user requests for usage of the vehicle when the vehicle is being rented to the first user, the usage right lending unit allows the second user to use the vehicle as long as the second user satisfies a lending condition.

Abstract: A car sharing system includes a car share device installed in a vehicle. The car share device includes a key function unit configured to verify an electronic key ID used by an electronic key system of the vehicle. The car sharing system further includes a key function invalidating unit that invalidates the key function unit when a condition is satisfied for switching the key function unit from a valid state to an invalid state.
