Outline
Based on the vehicle-vehicle oblique collision accident scenario caused by cooperative obstacle avoidance, this paper analyzes the displacement response and occupant injury. 2 variables are selected, namely the barrier residual vehicle speed and the collision overlap rate: 4 types of barrier vehicle speeds and 3 types of collision overlap rates are set respectively. The displacement phenomenon of occupants caused by cooperative obstacle avoidance and occupants injuries during the collision process are analyzed; the active pre-tensioning seat belt is matched and its restraint effect on the displaced occupants is analyzed. The results show that cooperative obstacle avoidance can cause obvious lateral displacement of the occupants, reducing the protective effect of the basic restraint system, especially for right-leaning seated occupants, the seat belt has completely detached from the occupants' shoulders. From the analysis results of the test matrix, the occupant will suffer the highest comprehensive damage when the collision overlap rate is about 30%. The restraint system equipped with active seat belt has good restraint effect on the displacement movement of the occupants during the cooperative obstacle avoidance process. The lateral displacement of the occupants is significantly reduced, and the comprehensive injury risk of the occupants decreases, whereas there is still a high risk of injury to the occupants' heads in the collision condition with a 50% overlap rate.
