System and method for adjusting pressing feeling by seat belt

A system for adjusting seat belt pressure, the system comprising:

• multiple markers attached at regular intervals on an outer surface of each of an upper webbing and a lower webbing;
• a body pressure sensor attached on an inner surface of each of the upper webbing and the lower webbing, and configured to detect a body pressure applied to a passenger's body by each of the upper webbing and the lower webbing;
• a camera configured to photograph positions of at least some of the markers, an upper webbing pull-out guiding D-ring, a buckle, and a lower webbing fixing body;
• a controller configured to determine whether the body pressure at a maximum protrusion point of each of the upper webbing and the lower webbing is greater than or equal to a reference pressure based on a captured signal of the camera and a detection signal of the body pressure sensor;
• and
• webbing pressure adjustment drive devices configured to be driven to relieve the body pressure to be less than the reference pressure based on a control signal of the controller in response to the body pressure at the maximum protrusion point being greater than or equal to the reference pressure.
