SYSTEM AND METHOD FOR CONTROLLING VEHICLE AT INTERSECTION
First Claim
1. A system for controlling vehicles at an intersection, comprising:
- a simultaneous starting group designating unit configured to designate a simultaneous starting group of vehicles, which are to enter the intersection in a same batch, among all vehicles to be entering the intersection, the simultaneous starting group having a session key issued thereto, different simultaneous starting groups having different session keys;
a message generating unit configured togenerate a start request message for the simultaneous starting group, andencrypt the start request message using its corresponding session key; and
a control unit configured to control the transmission of the session key and the start request message to the vehicles in the simultaneous starting group.

Abstract
Disclosed are a system and a method for controlling a vehicle at an intersection, and more particularly, disclosed is a technology that can efficiently control a start time of a vehicle that is waiting for a signal at an intersection. The system includes: a simultaneous starting group designating unit which designates vehicles of a simultaneous starting group, which are capable of starting simultaneously, among waiting vehicles when receiving an intersection entering state message from vehicles; a session key generating unit generating a session key for the simultaneous starting group; a message generating unit which generates a start request message for the simultaneous starting group; and a control unit which receives the intersection entering state message and transmits the session key and the start request message to the vehicles corresponding to the simultaneous starting group.

11. A system for controlling vehicles at an intersection, comprising:
-
an intersection control device configured to designate a simultaneous starting group of vehicles, which are to enter the intersection in a same batch, among all vehicles to be entering the intersection, the simultaneous starting group having a session key issued thereto, different simultaneous starting groups having different session keys, and to transmit a start request message to the vehicles in the simultaneous starting group; and a vehicle guide device of each of the vehicles, configured to transmit an intersection entering state message to the intersection control device when said each vehicle is to enter the intersection, and transmit a vehicle start response signal to the intersection control device when the start request message is transmitted to said each vehicle and said each vehicle is in the simultaneous starting group. - View Dependent Claims (12, 13, 14, 15, 17)

18. A method for controlling vehicles at an intersection, comprising:
-
receiving an intersection entering state message from each of the vehicles to be entering the intersection; determining whether a position of each of the vehicles that receive the intersection entering state message is within a simultaneous start range; registering all vehicles of which the positions are determined to be within the simultaneous start range in a simultaneous starting group, and storing information on the vehicles in a storage unit; generating a start request message and a session key for the simultaneous starting group, different simultaneous starting groups having different session keys, and encrypting the start request message using the session key; and transmitting the start request message and the session key to each vehicle upon registering said each vehicle in the simultaneous starting group. - View Dependent Claims (19, 20)
