Valet key control system and valet key
A valet key control system includes a time monitoring unit and a communication subject setting unit. The time monitoring unit is configured to monitor a remaining time of a reserved period during which the valet key is allowed to be used as the vehicle key. The communication subject setting unit is configured to set a communication subject of the valet key in accordance with the remaining time of the reserved period.
1. A valet key control system that controls a valet key usable as a vehicle key when lending a vehicle to a third person, the valet key control system comprising:
a time monitor that monitors a remaining time of a reserved period during which the valet key is allowed to be used as the vehicle key; and
a communication subject setter that switches a communication subject of the valet key between the vehicle and a mobile terminal, differing from the valet key, of a user of the vehicle in accordance with the remaining time of the reserved period,
wherein when the remaining time of the reserved period is shorter than a threshold time, the communication subject setter sets the communication subject of the valet key to the mobile terminal to obtain permission to allow the valet key to be continuously used after the reserved period ends from the mobile terminal or an external device that communicates the mobile terminal, and
wherein when the remaining time of the reserved period is greater than or equal to the threshold time, the valet key is allowed to be used as the vehicle key.
2. The valet key control system according to claim 1 , further comprising a time extension processor that extends the reserved period of the valet key, wherein
the communication subject setter sets the communication subject of the valet key to the mobile terminal when the remaining time of the reserved period is zero or close to zero, wherein the mobile terminal is allowed to be used as the vehicle key, and
the time extension processor, in response to the communication subject of the valet key being set to the mobile terminal, transmits a request for extension of the reserved period to the mobile terminal or the external device via the mobile terminal to request for permission of extension of the reserved period so as to allow the valet key to be continuously used after the reserved period ends.
3. The valet key control system according to claim 2 , wherein the time extension processor sends the request for extension of the reserved period via the mobile terminal to the external device, wherein the request for extension includes designating a new reserved period to extend the reserved period.
4. The valet key control system according to claim 1 , wherein
the valet key is used in a car sharing system including the vehicle,
the car sharing system includes a car share device that performs wireless communication with the mobile terminal that functions as the vehicle key when code information is registered to the mobile terminal, and
the car share device authenticates the code information through wireless communication with the mobile terminal and permits actuation of an on-board device of the vehicle with an electronic key system of the vehicle if the mobile terminal is operated after the code information is authenticated.
5. A valet key usable as a vehicle key when lending a vehicle to a third person, the valet key comprising:
a time monitor that monitors a remaining time of a reserved period during which the valet key is allowed to be used as the vehicle key; and
a communication subject setter that switches a communication subject of the valet key between the vehicle and a mobile terminal, differing from the valet key, of a user of the vehicle in accordance with the remaining time of the reserved period,
wherein when the remaining time of the reserved period is shorter than a threshold time, the communication subject setter sets the communication subject of the valet key to the mobile terminal to obtain permission to allow the valet key to be continuously used after the reserved period ends from the mobile terminal or an external device that communicates the mobile terminal, and
wherein when the remaining time of the reserved period is greater than or equal to the threshold time, the valet key is allowed to be used as the vehicle key.
