This key information generation system generates key information necessary when using a shared device and imparts this key information to a mobile terminal. Authentication is performed between a mobile terminal which has imported key information, and an authentication device provided to the device, and if said authentication is successful, the mobile terminal enables operation of the device via the authentication device. The key information generation system includes: an information management unit which manages, by associating with one another, individual information for the authentication device, a key information generating code, and usage information pertaining to the use of the authentication device; and a key information generation unit which specifies a key information generation code from the individual information and usage information managed by being associated with one another by the information management unit, and generates key information on the basis of the key information generation code.

Key information generation system and key information generation method

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.

Car sharing system

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.

This key information generation system generates key information required when using a shared vehicle, and imparts this key information to a mobile terminal. Authentication is performed between a mobile terminal containing the imparted key information, and an authentication device provided to a vehicle, and if said authentication is successful, the mobile terminal enables operation of the vehicle via the authentication device. The key information generation system includes: an information management unit which manages, by associating with one another, individual information for the authentication device, a key information generation code, and usage information pertaining to the use of the authentication device; and a key information generation unit which specifies a key information generation code from individual information and usage information managed by being associated with one another by the information management unit, and generates key information on the basis of the key information generation code.

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.

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.

A mobile device possessed by a user is equipped with: a motion sensor which is capable of detecting the motion of the mobile device; a receiver which is capable of receiving a polling signal transmitted from equipment; and a control unit which is configured so as to set, in response to whether or not the polling signal has been received by the receiver, the sampling speed with which the motion sensor detects the motion of the mobile device.

Mobile device

A portable device for preventing communication errors caused by disturbance such as noise. The portable device receives a first request signal from a communication controller and transmits a first response signal corresponding to the first request signal. A transmitter transmits the first response signal with a selected one of a plurality of frequencies. A transmission control unit transmits the first response signal from the transmitter with the one of the plurality of frequencies. The portable device further receives a second request signal from the communication control unit, which receives the first response signal. When the second request signal cannot be received, the portable device retransmits the first response signal from the transmitter with a frequency that differs from the one of the plurality of frequencies.
