1. A vehicle onboard unit comprising:
- a vehicle probe data collecting section configured to collect host vehicle probe data relating to external traveling conditions of a first vehicle having the onboard unit; and
a vehicle communication section,the vehicle onboard unit being configured to operate ina host vehicle mode in which the vehicle communication sectioncommunicates with the vehicle probe data collecting section to receive the host vehicle probe data of the first vehicle,prepares a host vehicle common message set by associating the host vehicle probe data with host vehicle identifying information of the first vehicle,communicates with at least one surrounding vehicle onboard unit disposed in at least one surrounding vehicle to collect at least one surrounding vehicle common message set which includes surrounding vehicle probe data associated with corresponding surrounding vehicle identifying information, andtransmits at least one of the host vehicle common message set and the at least one surrounding vehicle common message set to a vehicle onboard unit disposed in a different vehicle from the first vehicle, the different vehicle operating in a carrier vehicle mode of the vehicle onboard unit of the different vehicle; and
a carrier vehicle mode in which the vehicle communication sectioncommunicates with a vehicle onboard unit of a second vehicle operating in a host vehicle mode to receive at least one of a host vehicle common message set of the second vehicle and at least one surrounding vehicle common message set of at least one vehicle surrounding the second vehicle,disassociates host vehicle identifying information associated with the second vehicle and surrounding vehicle identifying information associated with the at least one vehicle surrounding the second vehicle to isolate host vehicle probe data and surrounding vehicle probe data after receiving the at least one of the host vehicle common message set and the at least one surrounding vehicle common message set, andtransmits at least one of the isolated host vehicle probe data and the isolated surrounding vehicle probe data to an external communication device.

Abstract
A vehicle information communication system is provided in which probe data or other private data relating to a host vehicle can be collected with anonymity. Basically, the host vehicle collects the probe data and sends the probe data to a carrier vehicle that disassociates the host vehicle'"'"'s identifying information (e.g., MAC address) from the data before the carrier vehicle sends the probe data to a roadside unit or other external communications station.

1. A vehicle onboard unit comprising:
-
a vehicle probe data collecting section configured to collect host vehicle probe data relating to external traveling conditions of a first vehicle having the onboard unit; and a vehicle communication section, the vehicle onboard unit being configured to operate in a host vehicle mode in which the vehicle communication section communicates with the vehicle probe data collecting section to receive the host vehicle probe data of the first vehicle, prepares a host vehicle common message set by associating the host vehicle probe data with host vehicle identifying information of the first vehicle, communicates with at least one surrounding vehicle onboard unit disposed in at least one surrounding vehicle to collect at least one surrounding vehicle common message set which includes surrounding vehicle probe data associated with corresponding surrounding vehicle identifying information, and transmits at least one of the host vehicle common message set and the at least one surrounding vehicle common message set to a vehicle onboard unit disposed in a different vehicle from the first vehicle, the different vehicle operating in a carrier vehicle mode of the vehicle onboard unit of the different vehicle; and a carrier vehicle mode in which the vehicle communication section communicates with a vehicle onboard unit of a second vehicle operating in a host vehicle mode to receive at least one of a host vehicle common message set of the second vehicle and at least one surrounding vehicle common message set of at least one vehicle surrounding the second vehicle, disassociates host vehicle identifying information associated with the second vehicle and surrounding vehicle identifying information associated with the at least one vehicle surrounding the second vehicle to isolate host vehicle probe data and surrounding vehicle probe data after receiving the at least one of the host vehicle common message set and the at least one surrounding vehicle common message set, and transmits at least one of the isolated host vehicle probe data and the isolated surrounding vehicle probe data to an external communication device. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8)

9. A vehicle information communication system comprising:
-
a host vehicle including a host vehicle onboard device having a vehicle probe data collecting section configured to collect host vehicle probe data relating to external traveling conditions of the host vehicle, and a host vehicle communication section configured to communicate with the host vehicle probe data collecting section to receive the host vehicle probe data, create a host vehicle common message set by associating the host vehicle probe data with host vehicle identifying information, and communicate with a surrounding vehicle onboard device of at least one surrounding vehicle to receive at least one surrounding vehicle common message set comprised of surrounding vehicle probe data associated with surrounding vehicle identifying information; and a carrier vehicle including a carrier vehicle onboard device having a carrier vehicle communication section configured to communicate with the host vehicle onboard device to receive a carrier request signal and to subsequently receive at least one of the host vehicle common message set and the at least one surrounding vehicle common message set in response to a reply sent from the carrier vehicle to the host vehicle, the carrier vehicle onboard device being further configured to disassociate the host vehicle identifying information from the host vehicle probe data and the surrounding vehicle identifying information from the surrounding vehicle probe data after receiving the at least one of the host vehicle common message set and the at least one surrounding vehicle common message set, and to transmit at least one of the host vehicle probe data and the surrounding vehicle probe data to an external communication device. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A vehicle information communication method comprising:
-
collecting host vehicle probe data and surrounding vehicle probe data in a host vehicle; transmitting the host vehicle probe data and the surrounding vehicle probe data from the host vehicle to a carrier vehicle; disassociating host vehicle identifying information from the host vehicle probe data and surrounding vehicle identifying information from the surrounding vehicle probe data after transmission from the host vehicle; transmitting the host vehicle probe data and the surrounding vehicle probe data from the carrier vehicle after disassociating the identifying information to an external communication device when the carrier vehicle is within a communication area of the communication device. - View Dependent Claims (21, 22, 23, 24, 25)
