A computer implemented method and computer system for automatically limiting the swing angle of a vehicle door to not hit nearby moving objects, including predicting that a moving object will move to be within a predetermined distance of the door and predicting the distance the moving object will be from the door, determining a swing angle extent of an opening of the door that will avoid hitting the moving object and actuating a door controller to limit the swing angle of the door. Historical data on the speed the door is opened can be used in determining the door swing angle. The current position and velocity of the moving object relative to the door of the vehicle is estimated based on signals received from sensors attached to the vehicle.
