An emergency braking method, for motor vehicles that enables the vehicle to brake in an automatic manner that is triggered when the distance between the vehicle in front is calculated to be less than the minimum distance (d_z), enables determining the starting time for braking by calculating the time when the speed of the ego vehicle and the vehicle in front are equalized, initiates braking at said time, enables three-phase braking within the braking sequence, the method comprising the following steps; - receiving measurement data from a camera and a radar located on the vehicle, - calculating the time until it stops, in case the braking sequence is initiated according to the measurement data received from the camera and the radar by a control unit (if braking sequence has started); and characterized in that - calculating the time elapsed until the speed of the ego vehicle is equalized with the vehicle in front, in case the braking sequence is initiated according to the measurement data received from the camera and the radar by the control unit (if braking sequence has started), - finding at which warning/braking stage the time of speed equalization with the vehicle in front occurs, - calculating the latest and minimum braking initiation distance (d_safe) by means of selecting one of the six different equations according to the result of the comparisons of whether the stage of warning/braking when the speed equalization moment is realized or not and the moment at which the vehicle in front reaches the stopping point is realized in the braking process or not, - starting the braking sequence if the distance to the vehicle in front measured instantly is less than or equal to the calculated minimum braking start distance, - going back to the beginning in order to make the calculation again, observing the changing vehicle dynamics again, - receiving measurement data from a camera and a radar located on the vehicle, - calculating the time until it stops, in case the braking sequence is initiated according to the measurement data received from the camera and the radar by a control unit (if braking sequence has started); and characterized in that - calculating the time elapsed until the speed of the ego vehicle is equalized with the vehicle in front, in case the braking sequence is initiated according to the measurement data received from the camera and the radar by the control unit (if braking sequence has started), - finding at which warning/braking stage the time of speed equalization with the vehicle in front occurs, - calculating the latest and minimum braking initiation distance (d_safe) by means of selecting one of the six different equations according to the result of the comparisons of whether the stage of warning/braking when the speed equalization moment is realized or not and the moment at which the vehicle in front reaches the stopping point is realized in the braking process or not, - starting the braking sequence if the distance to the vehicle in front measured instantly is less than or equal to the calculated minimum braking start distance, - going back to the beginning in order to make the calculation again, observing the changing vehicle dynamics again, - finding at which warning/braking stage the time of speed equalization with the vehicle in front occurs, - calculating the latest and minimum braking initiation distance (d_safe) by means of selecting one of the six different equations according to the result of the comparisons of whether the stage of warning/braking when the speed equalization moment is realized or not and the moment at which the vehicle in front reaches the stopping point is realized in the braking process or not, - starting the braking sequence if the distance to the vehicle in front measured instantly is less than or equal to the calculated minimum braking start distance, - going back to the beginning in order to make the calculation again, observing the changing vehicle dynamics again,
