“…The Hybrid III is the most widely used crash test dummy globally and has been employed by numerous researchers to assess occupant injuries in frontal crash tests. Audrey et al 29 used a Hybrid III dummy to simulate the kinematic response of a driver’s upper extremities to investigate damage caused by airbags. Through slide experiments, Devon et al 30 demonstrated that the Hybrid III dummy has a favorable kinematic response and biomimetic properties.…”

The safety of vehicle occupants in oblique collision scenarios continues to pose challenges, even with the implementation of Automatic Emergency Braking (AEB) systems. While AEB reduces collision risks, studies indicate it may heighten injury risks for out-of-position (OOP) occupants. To counteract this issue, the integration of active seat belts in vehicles equipped with AEB systems is recommended. Firstly, this study established an oblique angle collision scenario post-AEB activation using data from the Chinese National Automobile Accident In-depth Investigation System (NAIS) database, analyzed through Prescan software. The dynamic response of the vehicle was examined. Following this, finite element (FE) models were validated to assess the effects of collision overlap rate, AEB braking strategy, and active seat belt pre-tensioning on occupant injuries and kinematics. Under specific collision conditions, the impact of the timing and amount of seat belt pre-tensioning, as well as airbag deployment timing on occupant injuries, was also explored. Findings revealed that a 75% collision overlap rate significantly increases driver injury risk. Active seat belts effectively mitigate injuries caused by OOP statuses during AEB interventions, with the lowest Weighted Injury Criterion (WIC) observed at a pre-tensioning time of 200 ms for active seat belts. The study further suggests that optimal results in reducing occupant injuries are achieved when active pre-tensioning seat belts are complemented by appropriately timed airbag deployment.

How to evaluate driver spontaneous reactions in various collision patterns in a quantitative way is one of the most important topics in vehicle safety. Firstly, this paper constructs representative numerical crash scenarios described by impact velocity, impact angle and contact position based on finite element (FE) computation platform. Secondly, a driver cabin model is extracted and described in the well validated multi-rigid body (MB) model to compute the value of weighted injury criterion to quantitatively assess drivers’ overall injury under certain circumstances. Furthermore, based on the coupling of FE and MB, parametric studies on various crash scenarios are conducted. It is revealed that the WIC (Weighted Injury Criteria) value variation law under high impact velocities is quite distinct comparing with the one in low impact velocities. In addition, the coupling effect can be elucidated by the fact that the difference of WIC value among three impact velocities under smaller impact angles tends to be distinctly higher than that under larger impact angles. Meanwhile, high impact velocity also increases the sensitivity of WIC under different collision positions and impact angles. Results may provide a new methodology to quantitatively evaluate driving behaviors and serve as a significant guiding step towards collision avoidance for autonomous driving vehicles.

“…The variability in the postural orientation of the driver, during emergency vehicle manoeuvres, was recorded in a volunteer survey on a car driving simulator, through videos of occupants, in a virtual frontal collision scenario with a truck (Hault-Dubrulle, Robache, Pacaux, et al 2011). The main result was that none of the subjects adopted the standard driving position used in crash experiments.…”

“…Since airbags are usually mounted in the hub, this may represent a rather risky position. The influence of this outof-position (OOP) on injury outcome was extensively investigated with Hybrid III dummy but was restricted by a limited insight on upper extremity skeletal injury patterns (Hault-Dubrulle, Robache, Drazetic, et al 2011).…”
