Problems solved by technology
[0005] However, the prior art only considered the safety function of the pre-tightening motor safety belt itself, but failed to consider the great significance of the pre-tightening times of the pre-tightening motor safety belt
Therefore, since there is no clear definition of the exact times or mileage of the retractor pre-tightening, it is not conducive to after-sales services such as analyzing the driving state and replacing the seat belt in the later period.

The invention discloses an auxiliary device and an auxiliary method for a pre-tightening motor type safety belt. The auxiliary device comprises a detection device, a record storage unit, an analysis unit and a promoting unit, wherein the detection device is used for detecting a pre-tightening operation of the pre-tightening motor type safety belt, the record storage unit is used for recording and storing times of the detected pre-tightening operation, the analysis unit is used for comparing the times with a scheduled threshold to obtain a comparison result, and the promoting unit is used for performing vehicle condition and safety measures promotions according to the comparison result. The auxiliary device and the auxiliary method for the pre-tightening motor type safety belt have the advantages that significances of the pre-tightening times of the safety belt can be fully exerted to improve the vehicle condition and safety measures.
Description
technical field [0001] The invention relates to automobile safety technology, in particular to an auxiliary device and an auxiliary method for a pre-tightened motor safety belt. Background technique [0002] Pre-tensioned seat belts (PRETENSIONER SEAT BELT) are also called pre-shrunk seat belts. The feature of this kind of seat belt is that when the car has a collision accident and the occupant has not moved forward, it will first tighten the webbing, immediately tie the occupant tightly to the seat, and then lock the webbing to prevent the occupant from leaning forward. , effectively protect the safety of the occupants. The retractor that plays the main role in the pre-tensioned seat belt is different from the ordinary seat belt. In addition to the function of retracting the webbing of the ordinary retractor, it also has the ability to strengthen the restraint of the occupant in about 0.1s when the vehicle speed changes sharply. force, so it also has controls and pretensi...
