Vehicular communication system
First Claim
1. A vehicular communication system including (i) an in-vehicle apparatus in a vehicle and (ii) a portable apparatus held by an occupant of the vehicle,the in-vehicle apparatus containing a database storage device to store an application program and an activation section to activate the application program in the database storage device of the in-vehicle apparatus,the portable apparatus containing a database storage device to store an application program and an activation section to activate the application program in the database storage device of the portable apparatus,the in-vehicle apparatus and the portable apparatus intercommunicating with each other when a short range wireless communication link is connected,the vehicular communication system comprising:
- a changeover determination section to determine whether a changeover operation is made based on a manipulation by the occupant to cause a changeover in an application program in a database storage device of one of the in-vehicle apparatus and the portable apparatus; and
a synchronization section to perform an application program synchronization operation in cases that the changeover determination section determines that the changeover operation is made in the one of the in-vehicle apparatus and the portable apparatus under a state that the short range communication link is connected between the in-vehicle apparatus and the portable apparatus,the application program synchronization operation ensuring that the application program stored in the database storage device of the in-vehicle apparatus and the application program stored in the database storage device of the portable apparatus become identical to each other.

Abstract
Under a state where an in-vehicle navigation apparatus and a cellular phone intercommunicate with each other by connecting a Bluetooth communication link, when a changeover relative to an application program is determined in one of the in-vehicle navigation apparatus and the cellular phone, an application program synchronization operation is executed such that the application program stored in the in-vehicle navigation apparatus and the application program stored in the cellular phone become identical to each other.

9. A method in a vehicular communication system including an in-vehicle apparatus in a vehicle and a portable apparatus held by an occupant of the vehicle, the in-vehicle apparatus and the portable apparatus intercommunicating with each other when a short range wireless communication link is connected therebetween in the vehicle,
the in-vehicle apparatus having a database storage device storing an application program group containing different application programs in association with identification information of the different application programs, the portable apparatus having a database storage device storing an application program group containing different application programs in association with identification information of the different application programs, the method for synchronizing between the application program group of the in-vehicle apparatus and the application program group of the portable apparatus, the method comprising: -
determining that a changeover operation is made based on a manipulation by the occupant to cause a changeover in an application program group in a database storage device of one of the in-vehicle apparatus and the portable apparatus; performing, upon the determining, a collation to collate between the application program group of the in-vehicle apparatus and the application program group of the portable apparatus, to determine a difference therebetween; applying, based on the difference determined in the collation, an application program synchronization operation to an other of the in-vehicle apparatus and the portable apparatus, the application program synchronization operation ensuring that the different application programs stored in the in-vehicle apparatus and the different application programs stored in the portable apparatus become identical to each other; and activating concurrently a first application program stored in the in-vehicle apparatus and a second application program stored in the portable apparatus, the second application program being identical to the first application program to enable cooperative processing in two of the in-vehicle apparatus and the portable apparatus via the short range wireless communication link connected between the in-vehicle apparatus and the portable apparatus.
