Collision mitigation and vehicle transportation safety using integrated vehicle dynamics control systems

- Integrated vehicle dynamics control systems for collisions improvement.
- Development of a new dynamics/crash mathematical model for vehicle collisions.
- Development of a new occupant-based lumped mass-spring-damper mathematical model.
- Vehicle response and occupant behaviour are captured and analysed accurately.

The aim of this paper is to investigate the effect of vehicle dynamics control systems (VDCS) on both the collision of the vehicle body and the kinematic behaviour of the vehicle's occupant in case of offset frontal vehicle-to-vehicle collision. A unique 6-degree-of-freedom (6-DOF) vehicle dynamics/crash mathematical model and a simplified lumped mass occupant model are developed. The first model is used to define the vehicle body crash parameters and it integrates a vehicle dynamics model with a vehicle front-end structure model. The second model aims to predict the effect of VDCS on the kinematics of the occupant. It is shown from the numerical simulations that the vehicle dynamics/crash response and occupant behaviour can be captured and analysed quickly and accurately. Furthermore, it is shown that the VDCS can affect the crash characteristics positively and the occupant behaviour is improved.
