Vehicle control system
A vehicle control system includes a vehicle apparatus and a key. A confirmer of the vehicle apparatus is configured to confirm existence or non-existence of a second key, which is different from a first key, in a vehicle interior in response to locking of a vehicle by the first key. An authenticator of the key is configured to perform an authentication for authenticating that a user using the key is an authenticated user. An effectivity controller of the vehicle apparatus is configured to disable a function of a permitter concerning the second key when the second key exists in the vehicle interior and the authentication concerning the second key is unsuccessful. The effectivity controller is configured to enable the function of the permitter concerning the second key when the second key exists in the vehicle interior and the authentication concerning the second key is successful.
1. A vehicle control system comprising:
a vehicle apparatus configured to be mounted to a vehicle; and
a key configured to be carried by a user of the vehicle and to have wireless communication with the vehicle apparatus, wherein
the vehicle apparatus includes a permitter configured to permit predetermined manipulation on the vehicle based on wireless communication with the key,
the key includes:
an authenticator configured to perform an authentication for authenticating that the user using the key is an authenticated user; and
a transmitter configured to transmit an authentication result signal corresponding to a result of the authentication to the vehicle apparatus,
the key includes a first key and a second key different from the first key,
the vehicle apparatus further includes:
a confirmer configured to confirm existence or non-existence of the second key in a vehicle interior by attempting wireless communication with the second key in the vehicle interior in response to locking of the vehicle by the first key; and
an effectivity controller configured to:
disable a function of the permitter concerning the second key when the confirmer confirms the existence of the second key in the vehicle interior and the authentication result signal concerning the second key indicates that the authentication is unsuccessful; and
enable the function of the permitter concerning the second key when the confirmer confirms the existence of the second key in the vehicle interior and the authentication result signal concerning the second key indicates that the authentication is successful.
2. The vehicle control system according to claim 1 , wherein
the authenticator is configured to perform the authentication based on communication with a portable apparatus configured to be carried by the authenticated user and having a communication function.
3. The vehicle control system according to claim 2 , wherein
the confirmer is configured to transmit, toward the vehicle interior, a confirmation signal for confirming the existence or non-existence of the second key in response to the locking of the vehicle by the first key,
the confirmer is further configured to determine the existence or non-existence of the second key in the vehicle interior based on existence or non-existence of a response signal transmitted from the second key in reply to the confirmation signal, and
the authenticator is configured to start the authentication with the portable apparatus in response to receiving the confirmation signal.
