Vehicle safety belt control system and vehicle safety belt control method

Abstract

The invention provides an automobile safety belt control system, and further relates to an automobile safety belt control method. The automobile safety belt control system comprises a safety belt assembly and a controller; the safety belt assembly comprises an ultrasonic motor, a safety woven belt, a spring bolt, a lock latch and a guiding rail; the ultrasonic motor is fixed to one side of an automobile seat, one end of the spring bolt is movably connected to the safety woven belt, the lock latch is fixed to the guiding rail, the guiding rail is connected with the ultrasonic motor, and the spring bolt is connected to the lock latch in assembling, disassembling and clamped modes; the controller is connected with the ultrasonic motor and used for controlling the ultrasonic motor to drive theguiding rail to move; and the controller is connected with the ultrasonic motor and used for controlling the ultrasonic motor to drive the guiding rail to move. The automobile safety belt control system has the force limiting function, safety and comfortableness are improved, and meanwhile, the structure of a traditional safety belt mechanism is simplified.

Description

technical field [0001] The invention relates to the technical field of car seat belts, in particular to a car seat belt control system and a car seat belt control method. Background technique [0002] Seat belts in vehicles are designed to be used in the event of a collision, sudden braking or emergency stop, by preventing the person wearing the seat belt from striking a hard part of the vehicle interior or other occupants of the vehicle and by preventing the wearing of the seat belt from Persons are thrown from the vehicle to minimize injury to passengers. [0003] Many vehicles are equipped with three-point seat belts, which include a shoulder belt placed diagonally across the occupant's chest and a pelvic restraint placed across the occupant's pelvis to distract the vehicle Impact forces on the occupant's chest, pelvis and shoulders. It is the future development trend of seat belts to have force limiting function, vibration function, active pretensioning function and em...

AI Technical Summary

Problems solved by technology

Therefore, the more functions of existing seat belts, the more complex the structure and the heavier the weight

[0004] Moreover, for the emergency pretensioning function of the seat belt, once the gas generator is detonated, it cannot be used again next time, and the entire set of seat belts must be replaced immediately.

[0005] In addition, for the force-limiting function of the seat belt, when the tension of the seat belt is very large, once the tension of the seat belt reaches the limit value, the force-limiting rod will be permanently damaged, and the entire set of seat belts must be replaced.

[0006] In addition, when the gas generator is detonated, it will produce an instantaneous impact force, which will cause great damage to the elderly and weak, and the ribs and collarbone will be broken

[0007] The existing safety belts have even bigger defects, because the existing whole set of safety belts has a complex structure, and each function is integrated by different mechanisms to form a force-limiting function, a vibration function, an active pre-tightening function and an emergency pre-tightening function. When the seat belt cooperates with the vehicle safety system, according to the various early warning signals generated by the vehicle safety system, the various mechanisms on the retractor perform corresponding functions, that is to say, the early warning signals generated by the vehicle safety system are different. The mechanism of the corresponding function is different, which makes it difficult to cooperate with the seat belt and the vehicle safety system
