The invention provides a safety belt lock catch, a safety belt device and a vehicle control method, and relates to the technical field of automobile safety belts, the safety belt lock catch comprises a lock catch body and a detection device, the detection device comprises a tension-compression sensor, when a spring bolt connected with a safety belt braid is inserted into the lock catch body, a locking structure in the lock catch body is used for locking the spring bolt, and the tension-compression sensor is used for detecting the tension-compression sensor. The tension and compression sensor is connected with the locking structure, and the tension and compression sensor is used for detecting the pull-back force of the safety belt braid connected with the spring bolt relative to the lock catch body through the locking structure. The vehicle body control module can be combined with the pull-back force to judge whether the safety belt is correctly worn or not and judge the type of the passenger, for example, the passenger is judged to be a young child passenger or a passenger with the body shape larger than that of a fifth-percent woman, and the safety belt wearing recognition accuracy of the vehicle is improved.
本发明提供了一种安全带锁扣、安全带装置及车辆控制方法,涉及汽车安全带技术领域,安全带锁扣包括扣本体和检测装置,检测装置包括拉压传感器,当连接有安全带织带的锁舌插入锁扣本体时,锁扣本体内的锁定结构用于锁定锁舌,拉压传感器与锁定结构连接,且拉压传感器用于通过锁定结构检测连接有锁舌的安全带织带相对于锁扣本体的回拉力。车身控制模块可以结合该回拉力进行判断安全带是否正确佩戴及判定乘员的类型,例如判定乘员是年龄较小的儿童乘员,还是体型大于第五百分位女性的乘员,提高了车辆对安全带佩戴识别的准确性。
