Disclosed are an apparatus and a method for controlling vehicle collision avoidance. The apparatus includes: a warning signal receiver configured to receive an emergency braking warning signal for a forward collision of a host vehicle; a traveling environment detector configured to detect object information, road information, and space information pertaining to areas in front of, to the side of, and in back of the host vehicle when the warning signal is received; an emergency braking determiner configured to determine whether a risk of a forward collision of the host vehicle is larger than or equal to a first threshold value when the warning signal is received; an avoidance area determiner configured to search for drivable lanes of the host vehicle and one or more candidate areas in the space according to the determined risk of the forward collision, calculate a score of each of the candidate areas, determine an avoidance area, and set an avoidance path for the avoidance area; and a control signal output unit configured to output steering and speed control signals for moving the host vehicle to the avoidance area along the avoidance path.
