Apparatus and method for preventing vehicle collision

An apparatus for preventing a vehicle collision, comprising:

• a communication unit configured to wirelessly communicate with a surrounding vehicle;
• a sensing unit configured to detect the surrounding vehicle and a lane;
• a traveling control module configured to control steering or braking of an ego vehicle;
• and
• a controller configured to:
• check whether a vehicle ahead is present and a vehicle ahead of the vehicle ahead is in a stopped state through the communication unit;
• control the ego vehicle to enter a collision avoidance mode from a normal driving mode in response to the vehicle ahead being present and the vehicle ahead of the vehicle ahead being in the stopped state;
• receive driving information including a driving mode of the vehicle ahead through the communication unit in the collision avoidance mode;
• determine whether the ego vehicle is capable of steering avoidance driving toward a neighboring lane through the sensing unit based on the driving information of the vehicle ahead in the collision avoidance mode;
• and
• control the ego vehicle to perform the steering avoidance driving toward the neighboring lane or to urgently brake, by controlling the traveling control module, based on a result of the determination so as to avoid a collision with the vehicle ahead of the vehicle ahead in the collision avoidance mode.
