摘要：

       集成主动预紧式安全带(IAPS) 是集成了若干高级驾驶辅助系统(ADAS) 的乘员约束保护系统。为开发和应用IAPS，该文研究了乘员对IAPS 的可接受度，提出了提高接受度的措施。进行了装有50% th 男性假人的座椅台架试验和20 名志愿者参与的实车道路实验；分析了IAPS 的一级预紧力、预紧频次、预紧噪音值3 因素对乘员可接受度的影响。结果表明：不同志愿者对一级预紧力感觉不舒适的最小阈值存在差异，可将一级预紧力定为124 N ；原IAPS 有较高的预紧频次，可优化触发一级预紧功能的即碰时间(TTC) 来降低此阈值；预紧噪音值不会对乘员造成额外的干扰。因而，这些优化措施，可提升乘员对IAPS 的可接受度。

Abstract:

Integrated active pretension seatbelt (IAPS) is an occupant restraint protection system integrated with several advanced driving assistance systems (ADAS). This paper investigated the occupant acceptance to IAPS, and gave some measures to improve the acceptance for developing and applying the IAPS. The bench test with a 50% th male dummy and the road test with 20 volunteers were carried out. The effects of three factors on occupant acceptability, i.e. the first-level pre-tensioning, the pre-tensioning frequency and the pre-tensioning noise value, analyzed. The results show that the minimum threshold of discomfort caused by the primary pre-tensioning is different among different volunteers, when the primary pre-tensioning is set at 124 N. Optimizing the TTC (time to crash) reduces the threshold value when original IAPS has a higher pre-tensioning frequency while the pre-tensioning noise value does not cause additional  interference to the occupants. Therefore, these optimization measures improve occupants' acceptability to the IAPS.
