description | The present invention relates to a method for generating a real-time speed profile, capable of predicting a stopping distance based on the vehicle motion characteristics of a self-driving tram and generating a driving trajectory by referring to a speed limit of a driving route, and a trajectory generating unit therefor. More specifically, provided are the method for generating a real-time speed profile of a self-driving tram, capable of estimating the maximum stopping distance based on the current state of a self-driving tram trajectory, the maximum acceleration of a system, and a jerk limit, and generating a target trajectory by referring to a speed limit value of the corresponding location, to effectively implement real-time trajectory regeneration according to a change in driving conditions on a route, and the trajectory generating unit therefor.
