Simulering och Emulering av Vattenspray för Validering av Optiska Sensorer

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 AI-SEE project in Euripides2 Penta to strengthen relations internationally through participation in workshops and coordinated demonstrations between the projects.

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 spray of the existing spray rig and to see that the simulated spray correlates with actual, collected spray data. The sensor carrier will also be used to help evaluate the reproduction of spray scenarios.

The project is divided into four work packages. AP1 is responsible for project management, demonstration and synchronization of the work with AI-SEE. AP2 will identify and build water spray scenarios in simulation based on data collected by e.g. Veoneers test vehicle. In AP3, dynamic spray tests are set up on AstaZero where measurement data on aerosols formed by vehicles can be produced under well-defined conditions. AP4 will recreate similar scenarios as AP3 in spray rigs in order to be able to validate and recreate aerosol and turbulence as previously observed with a similar measurement method.
