On-vehicle apparatus and control method
An on-vehicle apparatus includes: a storage that stores apparatus information related to an external apparatus, the apparatus information being stored for registering the external apparatus as a first apparatus capable of using the on-vehicle apparatus; and a controller that deletes the apparatus information stored in the storage when a use of the on-vehicle apparatus using the external apparatus registered as the first apparatus is determined to have ended.
1 . An on-vehicle apparatus, comprising:
a storage that stores apparatus information related to an external apparatus, the apparatus information being stored for registering the external apparatus as being capable of using the on-vehicle apparatus; and
a controller configured to delete the apparatus information stored in the storage when a use of the on-vehicle apparatus using the external apparatus is determined to have ended,
wherein the controller:
accepts a selection as to whether or not to set the external apparatus to be registered as a first apparatus, and when the selection to set the external apparatus to be registered as the first apparatus is accepted, stores in the storage the apparatus information that uniquely identifies the external apparatus in association with a flag indicating registration as the first apparatus; and
when determining that the use of the on-vehicle apparatus using the external apparatus registered as the first apparatus has ended, does not delete the apparatus information that uniquely identifies the external apparatus stored in association with the flag in the storage.
2 . The on-vehicle apparatus according to claim 1 , wherein
the storage stores the apparatus information for registering the external apparatus as a second apparatus capable of using the on-vehicle apparatus, and
the controller does not delete the apparatus information stored in the storage when a use of the on-vehicle apparatus using the external apparatus registered as the second apparatus is determined to have ended.
3 . The on-vehicle apparatus according to claim 2 , wherein the storage includes:
a first storage area that stores the apparatus information for registering the external apparatus;
a second storage area that stores the apparatus information for registering the external apparatus as the second apparatus; and
a third storage area that stores the apparatus information that uniquely identifies the external apparatus in association with the flag.
4 . The on-vehicle apparatus according to claim 1 , wherein
the controller accepts the selection on whether to register the external apparatus as the first apparatus, and when the selection to register the external apparatus as the first apparatus is accepted, registers the external apparatus as the first apparatus.
5 . The on-vehicle apparatus according to claim 1 , wherein
when the apparatus information that uniquely identifies the external apparatus and the flag are stored in association in the storage, the controller registers the external apparatus as the first apparatus without requiring the selection on whether to set the external apparatus to be registered as the first apparatus.
6 . The on-vehicle apparatus according to claim 1 , wherein
the controller determines that the use of the on-vehicle apparatus using the external apparatus has ended when communication between the on-vehicle apparatus and the external apparatus is cut off.
7 . The on-vehicle apparatus according to claim 1 , wherein
the controller determines that the use of the on-vehicle apparatus using the external apparatus has ended when a power supply of the on-vehicle apparatus is turned off.
8 . A control method for an on-vehicle apparatus, the control method comprising:
storing, in a storage, apparatus information related to an external apparatus, the apparatus information being stored for registering the external apparatus as being capable of using the on-vehicle apparatus;
deleting, by a controller, the apparatus information stored in the storage when a use of the on-vehicle apparatus using the external apparatus is determined to have ended;
accepting, by the controller, a selection as to whether or not to set the external apparatus to be registered as a first apparatus, and when the selection to set the external apparatus to be registered as the first apparatus is accepted, storing, in the storage, the apparatus information that uniquely identifies the external apparatus in association with a flag indicating registration as the first apparatus; and
when determining, by the controller, that the use of the on-vehicle apparatus using the external apparatus registered as the first apparatus has ended, maintaining the apparatus information that uniquely identifies the external apparatus in association with the flag in the storage.
