A system for operating a door of a vehicle is disclosed. The system may include an actuator configured to move the door between an open position and a closed position. The system may also include a controller configured to determine a first open-door angle associated with a predetermined first velocity profile, determine a second open-door angle based on the open position relative to the closed position, determine a second velocity profile based on the first open-door angle, the second open-door angle, and the first velocity profile, and control the actuator to operate the door according to the second velocity profile.
