CONVOY TRAVEL APPARATUS
First Claim
1. A convoy travel apparatus disposed in a subject vehicle that is equipped with a position measurement unit for regularly having a measurement of satellite positioning coordinates of the subject vehicle, the convoy travel apparatus comprising:
- a wireless communication unit regularly transmitting convoy travel information of the subject vehicle, the convoy travel information including latest satellite positioning coordinates of the subject vehicle and travel locus information made from one of (a) a predetermined number of latest measurements of the satellite positioning coordinates of the subject vehicle and (b) a travel locus defined by the predetermined number of latest measurements of the satellite positioning coordinates of the subject vehicle measured by the position measurement unit;
a convoy travel control unit performing convoy travel control of the subject vehicle based on the convoy travel information from other vehicles received by the wireless communication unit; and
a sender vehicle identification unit identifying a sender vehicle transmitting a convoy travel information currently received by the wireless communication unit, based on a comparison between the travel locus information included in the convoy travel information currently received and the travel locus information previously received, whereinthe convoy travel control unit determines, based on the sender vehicle identified by the sender vehicle identification unit, the convoy travel information transmitted by a forward vehicle to be followed by the subject vehicle, and performs the convoy travel control based on the convoy travel information of the forward vehicle.

Abstract
A convoy travel apparatus enables a convoy travel of a subject vehicle by regularly transmitting convoy travel information including the latest measurement of GPS positioning coordinates and predetermined number of preceding measurements of GPS positioning coordinates. By receiving the convoy travel information from other vehicles, the convoy travel apparatus of the subject vehicle identifies a sender vehicle of a current convoy travel information based on a comparison between a travel locus generated from the current convoy travel information and a past travel locus generated from a convoy travel information previously received. The identification of the sender vehicle leads to the identification of the information from a leader vehicle to be followed in the convoy travel control of the subject vehicle, thereby enabling a convoy travel of the subject vehicle based on the identified information.
