Transfer system for diagnosing vehicle and method thereof

A transfer method of diagnosing a vehicle, comprising:

• determining, by the controller, whether the vehicle is introduced into an input side of a diagnosing region;
• when the vehicle is introduced, moving, by the controller, the vehicle to a diagnosing position by clamping a forward wheel tire of the vehicle using a transfer unit;
• and
• diagnosing, by the controller, a performance of the vehicle, when the diagnosing is terminated, moving the vehicle to an output side of the diagnosing region by clamping the rear wheel tire of the vehicle by the transfer unit,
• wherein the transfer unit includes:
• a guide rail disposed in a moving direction of the vehicle in both sides of the diagnosing region;
• a moving body movably disposed along the guide rail;
• swing arms rotatably connected with a forward side and a rear side of the moving body, respectively, and concentrated inward to be disposed forward and rearward of a lower portion of a front wheel tire or a rear wheel tire of the vehicle;
• free rollers rotatably disposed at each side of each swing arm concentrated inward to rotatably clamp the tire, respectively;
• a swing arm driving unit configured to provide a driving force to concentrate the swing arms inward or unfold the swing arms outward;
• and
• a moving body moving unit configured to move the moving body along the guide rail forward and rearward, and
• wherein when the vehicle is introduced into the diagnosing region, the transfer unit is configured to clamp and move a forward tire of the vehicle forward, and when the vehicle is discharged from the diagnosing region, the transfer unit is configured to clamp the rear wheel of the vehicle to move the vehicle to an outside.
