The invention discloses a motor pre-tightening active safety belt control system. The motor pre-tightening active safety belt control system comprises: an impact sensor, a power tightening device, ananti-reversion structure, a tension limiter and an electronic control unit. In this way, according to the motor pre-tightening active safety belt control system, the safety belt is tightened in time through the power tightening device, a person is fixed to a seat at the first moment when an accident happens, after the accident happens, the safety belt is properly loosened through the tension limiter, when an impact force peak is reached or the person can be protected by an air bag, the length of the safety belt is properly loosened, and the situation that ribs of the person are injured due totoo large tension is avoided.

    本发明公开了一种电机预紧主动式安全带控制系统,包括:冲击传感器、动力收紧装置、防逆转结构、拉力限制器和电子控制单元。通过上述方式,本发明电机预紧主动式安全带控制系统,通过动力收紧装置,及时收紧安全带,在事故发生的第一时刻把人固定在座椅上,事故发生后,通过拉力限制器适度放松安全带,待冲击力峰值过去,或者人已能受到气囊的保护时,适当放松安全带长度,避免因拉力过大而使人肋骨受伤。
