The invention discloses a safety belt control method and system.The control method comprises the steps that after a safety belt controller receives a body type signal and a collision signal, the explosion moment of a safety belt is determined; the safety belt controller sends out an explosion instruction according to the explosion moment, and the retractor conducts pre-tightening; when the stress of the safety belt reaches a preset pre-tightening threshold value, the safety belt controller sends a pre-tightening stopping instruction to the retractor after receiving the pre-tightening stopping signal; when the force borne by the safety belt reaches a preset force limiting threshold value, a force limiting instruction is sent out, and the safety belt starts to be loosened; during pre-tightening, pre-tightening force and force limiting values generated on different body types are different, damage to passengers caused by pre-tightening is reduced, and the passengers of different body types are protected; the explosion moment of the safety belt is comprehensively judged according to the body type of the passenger and the collision strength, so that the passengers with different body types can be protected; passengers with different body types are reminded to correctly wear the safety belts, and secondary injury of the safety belts to the passengers is prevented.

    本发明公开了一种安全带控制方法及系统,其中,控制方法包括当安全带控制器接收体型信号和碰撞信号后,确定安全带点爆时刻;安全带控制器根据点爆时刻发出点爆指令,卷收器进行预紧;当安全带受力达到预设的预紧阈值,安全带控制器接收停止预紧信号后,向卷收器发出停止预紧指令;当安全带受力里达到预设的限力阈值,发出限力指令,安全带开始放松;本发明预紧时对不同体型产生的预紧力和限力值是不同的,减少预紧对乘员造成的伤害以及对不同体型乘员起到保护作用;安全带的点爆时刻根据乘员体型和碰撞强度综合来判断的,对不同体型乘员都起到保护作用;提醒不同体型的乘员正确佩戴安全带,防止安全带对乘员造成二次伤害。
