Abstract: Disclosed is a technology for controlling safety message transmission between group driving vehicles. A system for controlling safety message transmission between group driving vehicles includes 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.
