Collision model for vehicle motion prediction after light impacts

Abstract: This article presents a collision model that predicts vehicle motions after a light impact. The focus of this work is on the characterisation of changes in vehicle kinematic states due to the impact; hence detailed analysis of vehicle component deformations is disregarded. Colliding vehicles are each modelled as rigid bodies with four degrees of freedom (longitudinal, lateral, yaw, and roll), which is different from the approach commonly used in the literature. The energy loss during impacts is accounted for t… Show more

“…This model should not only compute the collision forces generated within the short time span of contact, but also dictate the initial kinematic conditions for the ensuing motions after the impact. In this section, a previously developed model [9] for light impacts is applied to the PIT scenario. Unlike typical circumstances encountered in the studies on vehicle passive safety, usually no substantial structural deformation occurs in a PIT maneuver.…”

“…Therefore additional software has been adopted in simulating the collision phase of the errant vehicle behaviour. [9]. The successful development of these mathematical collision models, especially the momentum-based model, demonstrates that vehicle kinematic behaviour right after the collision could be calculated by using these models.…”

“…However, it seems to be an disadvantage because road monitoring could be expensive and impracticable. The suitable trajectory prediction and the lane change prediction are also studied in [7], [8], [9] and [10] in order to predict collisions and avoid accidents. This paper presents a method for predicting the future accidents using the estimation obtained with a lateral forces state observer (based on the Dugoff's tire model and FourWheel Vehicle model -FWVM) developed in Heudiasyc laboratory.…”
