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

There is provided a housing device configured to store an electronic key configured to perform wireless communication with an in-vehicle device, the housing device comprising: a housing formed by using a material that shields a first signal of a first frequency band transmitted by the in-vehicle device; a trigger signal reception antenna configured to receive a trigger signal transmitted by a portable device; and an actuator disposed inside the housing, and configured to operate an operation section installed in the electronic key based on the trigger signal, wherein the housing includes a passage structure that allows a second signal of a second frequency band to pass outside, the second signal being transmitted by the electronic key, and having a shorter wavelength than a wavelength of the first signal, and the second signal is used to control a control target device installed in the vehicle.

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.

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.

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.
