Embodiment Construction

[0028] figure 1 It is a schematic structural diagram of an intelligent active safety belt control system according to an embodiment of the present invention. Such as figure 1 As shown, an intelligent active seat belt control system provided by the present invention may generally include: a seat belt buckle sensor 1, an occupant monitoring sensor 2, a webbing tension sensor 3, a control unit 4 and an active pretensioning seat belt 5. The seat belt buckle sensor 1 is used to monitor the switch state of the seat belt buckle. When the seat belt buckle sensor 1 detects that the seat belt buckle is open, the seat belt is not fastened; when the seat belt buckle sensor 1 detects that the seat belt buckle is closed (not opened), the seat belt is fastened. The occupant monitoring sensor 2 is installed in the vehicle seat, and is used for monitoring whether there is a passenger on the seat. The webbing tension sensor 3 is installed on the webbing of the safety belt, and is used for m...

Abstract

The invention provides an intelligent active safety belt control system, and relates to the technical field of automobiles. The intelligent active safety belt control system comprises a safety belt latch sensor, a passenger monitoring sensor, a woven tape tension sensor, a control unit and an active pre-tightening safety belt, wherein the woven tape tension sensor is mounted on a safety belt woven tape and used for monitoring the tension of the safety belt woven tape, the control unit receives monitoring signals of the safety belt latch sensor, the passenger monitoring sensor and the woven tape tension sensor, vehicle gear signals and engine signals, judges safety belt use requirements and transmits control signals, the active pre-tightening safety belt comprises a motor, a retractor and the woven tape. The motor controls the retractor to push, retract or pre-tighten the woven tape according to the control signals. According to the intelligent active safety belt control system, an intelligent safety belt comfort adjusting function is developed according to different use scenes of drivers, use convenience and practicability of the safety belt are effectively improved, and driving experience is improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an intelligent active safety belt control system. Background technique [0002] Seat belt is one of the main protection devices of occupant restraint system, and it is an indispensable device on the seat of high-speed sports vehicles. Ordinary seat belts realize the protection function by restraining the rapid displacement of the occupant caused by the rapid acceleration generated when the vehicle collides. When the car collides, the seat belt restrains the occupant on the seat, so that the occupant's head and chest will not hit the steering wheel, instrument panel and windshield forward, reducing the risk of secondary collision of the occupant. [0003] The pre-tensioned seat belt is the same as the general seat belt under normal driving conditions, and the webbing can be freely stretched and retracted according to the needs of the occupants to ensure comfort. When the veh...
