The invention provides a safety belt control system comprising a safety belt, a ranging radar unit, a first analog-digital converter, pressure sensors, a second analog-digital converter, an electric reel and a controller. The safety belt comprises an outer fabric layer and an inner cushion layer. The ranging radar unit is disposed on front and rear bumpers of a vehicle and side door pillars thereof and is used for outputting ranging signals. The first analog-digital converter is connected to the ranging radar unit and is used for converting the ranging signals into digital signals. The pressure sensors are disposed on the periphery of a frame and are used for testing vehicle collision pressure and outputting pressure signals. The second analog-digital converter is connected to the pressure sensors and used for converting the pressure signals into digital signals. The electric reel is used for tensioning the safety belt. The controller is connected to the first analog-digital converter and the second analog-digital converter and controls the electric reel to tension the safety belt when the ranging signals reach a preset value. When the pressure signals reach the preset value, a safety airbag in the inner cushion layer of the safety belt is controlled to start up.
