VEHICLE COMMUNICATION APPARATUS
First Claim
1. A vehicle communication apparatus for communicating to/from an external portion through a communication terminal independent of a vehicle by performing short-range radio communications to/from the communication terminal by using short-range radio communication means, the vehicle communication apparatus comprising:
- vehicle information storage means for storing vehicle information acquired in accordance with travel of the vehicle in order in an updatable manner; and
information transfer means for transferring the vehicle information stored in the vehicle information storage means in order in the updatable manner to the communication terminal, wherein;
where there exists another short-range radio communication means for performing short-range radio communications to/from the vehicle, the short-range radio communication means establishes the short-range radio communications between the vehicle and the communication terminal after lapse of a predetermined time period after the vehicle information is stored in the vehicle information storage means; and
the information transfer means transfers the vehicle information stored in the vehicle information storage means next to the communication terminal.

Abstract
An information transfer ECU provided to a vehicle acquires and accumulates vehicle information output from a plurality of vehicle ECUs connected to a CAN communication line. Then, the information transfer ECU transfers the accumulated vehicle information to a portable information terminal to/from which short-range radio communications have been established by a short-range communication control unit. The portable information terminal transmits the transferred vehicle information to a vehicle information center through an external communication line network in order. When acquiring information for identifying the vehicle information whose transmission has been completed from the vehicle information center, the portable information terminal supplies the information to the information transfer ECU. The information transfer ECU erases the vehicle information whose transmission has been completed based on the acquired information.

4. A vehicle communication apparatus for communicating to/from an external portion through a communication terminal independent of a vehicle by performing short-range radio communications to/from the communication terminal by using short-range radio communication means, the vehicle communication apparatus comprising:
-
vehicle information storage means for storing vehicle information acquired in accordance with travel of the vehicle in order in an updatable manner; vehicle information discrimination means for discriminating the vehicle information stored in the vehicle information storage means between the vehicle information to be used by the external portion and the vehicle information to be used by the communication terminal; encryption processing means for encrypting respective pieces of vehicle information obtained by the vehicle information discrimination means through discrimination in different encrypted states; and information transfer means for transferring the respective pieces of vehicle information encrypted by the encryption processing means in the different encrypted states to the communication terminal, wherein the communication terminal decodes only the vehicle information to be used by the communication terminal of the respective pieces of vehicle information encrypted in the different encrypted states and transferred by the information transfer means, and transmits the vehicle information to be used by the external portion as it is in the encrypted state. - View Dependent Claims (5, 6, 7)

8. A vehicle communication apparatus for communicating to/from an external portion through a communication terminal independent of a vehicle by performing short-range radio communications to/from the communication terminal by using short-range radio communication means,
the vehicle comprising: -
a dedicated communication terminal mounted to the vehicle, for communicating to/from the external portion and the communication terminal through the external portion; and vehicle control means for acquiring instruction information for controlling the vehicle from at least one of the communication terminal and the dedicated communication terminal, and controlling the vehicle in accordance with the instruction information, the vehicle communication apparatus comprising; vehicle information storage means for storing vehicle information acquired in accordance with travel of the vehicle in order in an updatable manner; information transfer means for transferring the vehicle information stored in the vehicle information storage means in order in the updatable manner to the communication terminal and the dedicated communication terminal; direct communication means for allowing the vehicle and the communication terminal to directly communicate to/from each other through the short-range radio communications established by the short-range radio communication means; and indirect communication means for allowing the vehicle and the communication terminal to indirectly communicate to/from each other through the external portion by using the dedicated communication terminal, wherein the vehicle control means acquires the instruction information from the direct communication means more preferentially than from the indirect communication means when the vehicle and the communication terminal are allowed to perform the short-range radio communications to/from each other by the short-range radio communication means. - View Dependent Claims (9, 10, 13)
