Presentation

Method development of test track testing of a head on scenario

Head on collisions are high speed collisions and these mostly cause severe injuries of the persons in the vehicle. The speed at the impact is inevitably the sum of the two oncoming vehicle speeds. Volvo Cars decided to investigate how to address these types of accidents with our active safety function collision mitigation by braking. The aim is to primarily mitigate the injuries by reducing the speed at the impact, and not to have full avoidance in all cases. As the function is developed, the question on how to test it was raised. This presentation describes the development of the test methods for testing of such a function. A function that focus on high speeds and interact at a timing of very low time to collision.
