About this Webinar

Today, automotive vehicles have optical and electronic support systems like cameras or distance sensors. In the future, automated driving will require even more assisting systems like Lidar and Radar. Webasto has a long history in the development and production of roof systems. The company develops a Roof Sensor Module (RSM) for autonomous driving and built a functional RSM prototype vehicle.

What You Will Learn

In this webinar, you will learn:

  • How Webasto uses CFD to improve the functionality of the RSM cleaning system
  • How CFD allows Webasto engineers to understand the behavior of the cleaning spray under specific driving scenarios
  • How the application of several transition mechanisms, VOF-to-DPM, DPM-to-EWM and EWM-to-VOF has been successfully applied for RSM cleaning simulation
