VRU Protection Systems

Protecting vulnerable road users (VRUs) like pedestrians, cyclists, and vehicles is paramount in road traffic. However, determining the most effective system or combination of systems to minimize VRU injuries in real-life conditions poses challenges due to the vast possibilities and the need for early product development insights.

VIRTUAL VEHICLE’s method addresses this by enabling the evaluation of active, passive, and integrated VRU protection systems using identical injury criteria through simulation. This comprehensive approach, featuring an end-to-end tool chain for simulating various accident scenarios, facilitates the identification of optimal VRU protection configurations, enhancing road safety for all.

Structural Design and Crash Simulation

Predicting structural failure in vehicle crashes remains a significant challenge in virtual vehicle development, especially with the increasing use of lightweight materials and innovative joining techniques, which heightens material variety and structural complexity. Robust calculation methods are crucial for managing this complexity and ensuring reliable prediction results.

 

VIRTUAL VEHICLE’s L2 tool offers a modular framework that accurately models material failure under localized stress without compromising computing efficiency. Central to this methodology are efficient metamodels that consider relevant production and joining processes. Developed in collaboration with partners like VW, Audi, and Magna since 2004, this methodology has become an integral component of the industrial vehicle development process.
