Simulation and emulation of waterspray for validation of optical sensors (SEVVOS)
Research Project, 2022 – 2024

Purpose and goal: The purpose of the project is to be able to establish a method for simulation of water spray, emulation of water spray in rigs, and to check that the achieved results correlate with real data.
The project is also expected to provide a better foundation for rig and test method developed by AstaZero and Veoneer in the industry in the form of large European vehicle manufacturers. The goal is to collaborate with, among others, CARISSMA in the project AI-SEE in Euripides2 Penta to strengthen relations internationally through participation in workshops and coordinated demos between the projects Expected results and effects: Veoneer completes a vehicle (sensor carrier) that will collect data from public roads in different weather conditions. Collected data and databases (both open and from AI-SEE) then form the basis for simulation of water spray. A method for reproduction of spray is developed based on the simulations and measurement data from the method is then used to validate the existing spray rig spray and to see that it simulated the spray correlates with actual, collected spray data.The sensor carrier will also be used to help evaluate the reproduction of spray scenarios.
