Further Advancing Vehicle Safety for Everyone
Whenever you step into a car, you are surrounded by safety systems working to help prevent crashes and help protect you if one occurs. These systems, constantly refined through safety testing, have made vehicles safer year after year. However, current safety testing cannot evaluate all aspects of the crash and occupant characteristics. This research takes a closer look at the variability in crash and occupant characteristics, aiming to support further advancement in vehicle safety.

The research utilizes advanced computer simulations to understand the dynamics of crashes and occupant safety. It reveals that while automatic braking systems are getting better in preventing crashes, they also alter the characteristics of crashes that are not avoided. The remaining crashes might more frequently occur closer to the vehicle’s corners. This insight is key to developing more effective safety systems.

Further, the thesis examines seat belt interactions with occupants of varying sizes and shapes, using methods to quantitatively assess seat belt effectiveness for each individual. Such analysis could facilitate the development of adaptive safety systems, tailored to the unique needs of each occupant and crash scenario.

Ultimately, the goal is to contribute to more comprehensive methods for safety testing, supporting the development of safer vehicles and ensuring safer journeys for everyone.
