Platoon travel system
First Claim
1. A platoon travel system for organizing plural vehicles into platoon vehicles and performing a platoon travel of the platoon vehicles at a preset travel speed and a preset inter-vehicle distance from each other, the system comprising:
- at least one processor located in an Engine Control Unit (ECU), the at least one processor is configured to;
(i) organize, in a platoon organization unit, a platoon by acquiring, from each of the plural vehicles, projection area information indicative of a projection area of each vehicle and (ii) position, from a front of the platoon, vehicles in a larger projection area vehicle first manner in which the vehicles are arranged in a descending order of the projection areas from the front of the platoon;
determine whether a particular departing vehicle is departing from the platoon;
determine whether a particular joining vehicle is joining in the platoon; and
adjust, in an inter-vehicle distance adjustment unit, an inter-vehicle distance between the platoon vehicles at a vehicle joining time and at a vehicle departure time;
the vehicle joining time defined as when the particular joining vehicle is determined to be joining in the platoon;
in the vehicle joining time, the at least one processor is configured to adjust the inter-vehicle distance to the preset inter-vehicle distance by controlling, to be decelerated, deceleration target vehicles in the platoon which are traveling behind a particular join position that is reserved for the particular joining vehicle; and
the vehicle departure time defined as when the particular departing vehicle is determined to be departing from the platoon;
in the vehicle departure time, the at least one processor is configured to adjust the inter-vehicle distance to the preset inter-vehicle distance by controlling, to be decelerated, deceleration target vehicles in the platoon which are traveling ahead of the particular departing vehicle.

Abstract
A platoon travel system organizes a platoon having plural platoon vehicles traveling in two vehicle groups, in which a preset inter-vehicle distance is reserved between each of the platoon vehicles. When a new vehicle joins in the platoon, the platoon travel system adjusts the inter-vehicle distance by decelerating, among all platoon vehicles, deceleration target vehicles that are the platoon vehicles behind a join position in the platoon, which are included in a latter one of the two vehicle groups.
