PURPOSE: A smart cruise control device and a method are provided to virtually determine at least one peripheral vehicle as a target, and to control the target in order to minimize the sense of difference and the sense of resistance for a driver, thereby implementing autonomous driving of which the pattern is similar to general driving. CONSTITUTION: A smart cruise control method comprises: a first step of detecting whether or not the approach motion of a peripheral target in the direction of a subject vehicle exists; a second step of determining a smart cruise control target using target information outputted from a first target determining part when the approach motion of the peripheral target does not exist; and a third step of determining the smart cruise control target using target information outputted from a second target determining part when the approach motion of the peripheral target exists. In the second step, the closest target in the direction of the subject vehicle is determined as the smart cruise control target only using a curvature radius and a front target position. In the third step, the approaching probabilities of targets approaching in the direction of the subject vehicle are digitized, and then the closest target of which the approaching probability is more than a certain value among the targets is determined as a candidate target. A smart cruise control device comprises the first target determining part, the second target determining part, and a condition based target determining part. The first target determining part determines the target based on the direction of the subject vehicle. The second target determining part determines the candidate target based on the motional analysis of the target. The condition based target determining part determines the target using either of the first target determining part or the second target determining part depending on whether or not the approach motion of the peripheral target exists.
