Abstract
The paper presents the use of the evolutionary algorithm in the reconstruction of vehicle collisions to look for the point of the force impulse – Point of Impact (POI) and the Angle of the Tangent Plane (ATP) during the collision of two cars. The location of this point and the angle of the tangent plane of the collision are often decisive for the simulation of the vehicles' motion and the calculated pre-crash speeds. The simulation calculations have shown that the evolutionary algorithm allows the location of POI in the area of the highest energy consumption of a given collision. This is the area with the highest stiffness of the car's structure. The search for ATP has also been successfully completed. This allowed for a reliable calculation of vehicle pre-crash speeds. Calculations were validated based on the actual crash test. The presented quality and limitation functions (vehicle stopping area and track run) are based on checking whether the vehicle in the simulation movement has stopped at the place determined by the surface with given dimensions, and the trajectories of the wheels tracks coincide with the set corridors. The uncertainty of calculations is indicated.
