System and method for controlling safety message transmission between group driving vehicles
First Claim
1. A system for controlling safety message transmission between group driving vehicles, the system comprising:
- a setting unit configured to set a transmission time interval and a transmission power of a safety message;
a message type determination unit configured to analyze a safety message received, and determine whether the safety message is a general safety message or an emergency safety message;
a reception state determination unit configured to determine a reception state of the safety message transmitted from the message type determination unit; and
a control unit configured to generate a new transmission time interval and a new transmission power for safety message transmission based on a value of the reception state determined by the reception state determination unit, and transmit the generated new transmission time interval and new transmission power to the setting unit,wherein the reception state determination unit determines the reception state of the safety message transmitted from the message type determination unit by calculating a mean reception time difference based on the safety message currently received and previously received safety messages.

11. A method for controlling safety message transmission between group driving vehicles, the method comprising:
-
receiving a safety message transmitted from outside; determining whether the received safety message is a general safety message or an emergency safety message by analyzing the received safety message; determining a reception state of the received safety message if it is determined that the received safety message is an emergency safety message as a result of the determining of whether the safety message is a general safety message or an emergency safety message; generating a new transmission time interval and a new transmission power for safety message transmission if it is determined that the reception state of the received safety message is not good as a result of the determining of the reception state; and transmitting a safety message based on the new transmission time interval and the new transmission power, wherein in the determining of the reception state of the received safety message, calculating a mean reception time difference based on the received safety message and previously received safety messages. - View Dependent Claims (12, 13, 14, 15, 16, 17)
