The invention relates to the field of vehicle safety, in particular to a safety belt locking system and a vehicle. The safety belt locking system comprises a ratchet wheel, a voltage comparator, a magnet set and a coil, the magnet set is arranged on the outer side portion of the ratchet wheel, the coil is arranged outside the ratchet wheel, when the safety belt drives the ratchet wheel to rotate, the coil can cut magnetic lines of force of the magnet set, and the coil is connected with the normal phase input end of the voltage comparator. The inverted input end of the voltage comparator is provided with a reference value, and when the electromotive force of the normal input end is larger than the reference value, the voltage comparator controls the safety belt to be locked. According to the safety belt locking system, the problems that an existing belt sensing mechanism is prone to vibration in the automobile running process, noise is generated, and durability and sensitivity of products are affected are solved.
