Intelligent side step apparatus for vehicle

An intelligent side step apparatus for a vehicle, comprising:

• fixing rails, which are fixed with opposing ends positioned in a left-right direction of the vehicle, in which a door of the vehicle is positioned;
• a movable rail disposed along the fixing rails and slidable along the fixing rails in an axial direction of the fixing rails;
• a rotary link module that is combined with the movable rail and can adjust a height by rotation thereof;
• a step panel integrally combined with the rotary link module, wherein the step panel moves to the left and right of the vehicle together with the movable rail in the axial direction of the fixing rails, and adjusts a vertical height of the rotary link module;
• a rail actuator that provides power to slide the movable rail;
• a link actuator that provides power to rotate the rotary link module;
• a control unit that is configured to control operation of the rail actuator and the link actuator in response to a getting-on mode signal and a getting off mode signal of a passenger;
• a lower bracket fixed to the moveable rail;
• a pair of rotary links rotatably coupled to the lower end of the lower bracket;
• and
• an upper bracket rotatably coupled to the upper ends of the rotary links to connect the pair of rotary links and fixes the step panel.
