The invention relates to a vehicle and a method for controlling same. A vehicle includes: a sensor configured to detect an object moving in front of the vehicle; a controller configured to determine alongitudinal driving time taken for the vehicle to drive to the object, and configured to transmit a deceleration avoidance control signal gradually reducing a driving speed of the vehicle so that the vehicle is stopped before colliding with the object or a cross avoidance control signal stopping the vehicle until the object escapes from a driving lane of the vehicle, based on the longitudinal driving time and a transverse moving time of the object; and a speed regulator configured to regulate the driving speed of the vehicle in response to the transmitted control signal.
