Passenger self-adaptive lower limb restraint system and method and vehicle

Abstract

A passenger adaptive lower limb restraint system, method and vehicle, the system comprising: a passenger monitoring system, the passenger monitoring system monitoring a passenger position and a sitting posture, the sitting posture comprising a passenger pelvis position and a safety belt waistband position; the information processing system is used for judging the passenger diving risk according to the passenger position and the riding posture; and the execution system is opened or closed according to the diving risk, and the positions of knees and feet of the passenger are restrained by combining the position and the sitting posture of the passenger. By means of the self-adaptive lower limb restraint system, the problem that a passenger dives when a traditional instrument panel and a glove box cannot prevent lower limb movement due to the fact that the included angle between a backrest and a cushion of the passenger is increased or a seat is adjusted backwards is solved. Meanwhile, the moving posture of the passenger is adjusted in the frontal collision process, so that the co-driver air bag and the safety belt shoulder strap can play a role more effectively, and the injury to the passenger is reduced.

Description

technical field [0001] The present invention relates to a member safety system and method, and more particularly, to an occupant adaptive lower limb restraint system, method and vehicle. Background technique [0002] With the development of advanced assisted driving and autonomous driving, the seats in smart cockpits take on various forms. At present, the more popular front passenger seat uses new scenarios, including seat postures with different backrest angles, and a large range of front and rear movement of the long seat rails, which makes passengers more willing to adopt a semi-recumbent posture during long-distance travel. [0003] However, this frequently used new scenario can lead to security risks. Due to the rapid changes in the cockpit scene, the formulation of collision safety regulations and standards is relatively lagging behind. At present, the evaluation standards for occupant safety are still at the design positions stipulated in the evaluation standards, an...
