Abstract
Disclosed is an adaptive cruise control system using v2v communication and a control method thereof. The adaptive cruise control system for a vehicle using V2V communication includes: a relative distance/speed input unit receiving a relative distance and a relative speed between a recognized preceding vehicle and an own vehicle; a communication unit receiving road surface information from the recognized preceding vehicle; a constant changing unit comparing the received road surface information with road surface information received at a previous time and changing a V2V distance constant when the road surface information is changed in accordance with a result of the comparison; a target V2V distance calculation unit calculating a target V2V distance between the recognized preceding vehicle and the own vehicle based on the changed V2V distance constant; and a target acceleration calculation unit calculating the target acceleration of the own vehicle by using the received road surface information.
