Driver Assistance Systems have evolved dramatically during the last decade. In the early stage their use was limited due to high cost und technological restrictions in the premium segment. Today we witness a massive rollout phase into every car segment.
On the one hand this leads to higher volume on the other hand the accepted price from the customer is much lower than before without accepting too much compromises in functionality. This describes the challenge for OEMs as well as suppliers.
One approach of Volkswagen is to constantly question today’s hardware concepts concerning sensors and electronic control units (ECUs) for driver assistance systems. E.g. high cost radar sensors dominate the market for adaptive cruise control and side assistance systems. Focusing on the demand of the customers in the volume market leads to a dedicated design which is more cost effective and allows reaching low end platforms. The goal here is not to switch sensor technology completely but to find the important “minor” improvements.
Another motivation for such solutions are the new EU NCAP aims in the following years. The discussed regulations concerning pedestrian detection and active safety require very cost effective systems with the potential of added functionality. Without changing sensors and systems a functional update must enable extra benefits for the driver.
The paper will address these topics with examples from Volkswagen.
