Abstract: The purpose of the present invention is to provide a method for preventing vehicle collision in consideration of environment capable of ensuring safety by reducing the possibility of collision in the process of varying the timing of control such as warning and braking control if a danger of collision is detected in a dark environment narrowing the view of a driver such as driving in a tunnel or in the dark, and in case of rain affecting a braking distance. To achieve the purpose, the method for preventing vehicle collision in consideration of environment according to the present invention comprises the steps of: operating a control system for preventing collision; calculating the danger of collision with a preceding vehicle; applying the offset of a relative distance in case of receiving a detection signal from a rain sensor; changing the reference value of the danger of collision in case of receiving a detection signal from an illuminance sensor; and conducting warning and braking control after determining the danger of collision. The warning and braking control such as warning, pre-fill, pre-brake, brake assist, and active brake are conducted based on the danger of collision. And safety is enhanced based on the environment by ensuring a sufficient braking distance in case of rainfall and headlights turned on.
