Method and system for controlling a plurality of vehicles as a group unit
First Claim
1. A running vehicle group controlling method for automatically controlling a plurality of vehicles shifting from a branch road to a main road, wherein said method operates on the basis of a moving target method wherein a plurality of vehicles running on an actual road are associated to a plurality of moving targets on a computer, the moving targets are allocated to an imaginary road on the computer which corresponds to the actual road, and wherein said moving targets are used to track and control the vehicles running on the actual road, said running vehicle group controlling method comprising the steps of:
- detecting the vehicles that are shifting from the branch road to the main road as a joining vehicle group, wherein the joining vehicle group is operating under vehicle-to-vehicle distance control; and
associating only a head vehicle of the joining vehicle group with only one of the moving targets created by the computer, andallocating the one moving target to the head vehicle of the joining vehicle group so that a space adjacent to the one moving target is created by the computer on the imaginary road, whereby said space has a length corresponding to at least a length of the joining vehicle group, and whereby none of the non-associated moving targets are assigned to any of the vehicles in the detected vehicles.

Abstract
A system and method for controlling a group of vehicles running on a road under vehicle-to-vehicle control where a joining group of vehicles (10) approaching from a branch road (7) is controlled by a system employing a moving target control method applied to only the head vehicle (1) in the joining group (10). Vehicle joining is achieved when a head moving target (21) in a continuous null (not-allocated) group (40) of moving targets on the main road that has an overall length larger than that of the joining vehicle group approaching from the branch road (7) and the head moving target of the null group (40) is synchronized with the head vehicle of the joining group (10).

3. A running vehicle group controlling method for automatically controlling a plurality of vehicles running on a road, comprising the steps of:
-
allocating a moving target for joining to only a head vehicle in a joining vehicle group, wherein the joining vehicle group comprises a group of approaching vehicles joining a main road from a branch road, when the vehicles in the joining vehicle group are controlled as a unit under vehicle-to-vehicle control in order to maintain a constant vehicle-to-vehicle distance; and determining a length of the joining vehicle group approaching the main road from the branch road; and determining a length of a continuous, non-allocated group of moving targets on the main road; and setting a head moving target of a continuous, non-allocated group of moving targets on the main road in synchronism with the moving target for joining, when the length of the continuous, non-allocated group of moving targets on the main road is longer than the length of the joining vehicle group, in order to achieve joining of the joining vehicle group with the continuous moving target group on the main road. - View Dependent Claims (4)

5. A running vehicle group controlling system for automatically controlling a plurality of vehicles shifting from a branch road to a main road, wherein said system operates on the basis of a moving target method wherein a plurality of vehicles running on an actual road are associated to a plurality of moving targets on a computer, the moving targets are allocated to an imaginary road on the computer which corresponds to the actual road, and wherein said moving targets are used to track and control the vehicles running on the actual road, said running vehicle group controlling system comprising:
-
a detecting unit for detecting the vehicles that are shifting from the branch road to the main road as a joining vehicle group, wherein the joining vehicle group is operating under vehicle-to-vehicle distance control; and an associating unit for associating only a head vehicle of the joining vehicle group with only one of the moving targets created by the computer, wherein said associating unit allocates the one moving target to the head vehicle of the joining vehicle group so that a space adjacent to the one moving target is created by the computer on the imaginary road, whereby said space has a length corresponding to at least a length of the joining vehicle group, and whereby none of the non-associated moving targets are assigned to any of the vehicles in the detected vehicles. - View Dependent Claims (6, 7, 8)
