DEVELOPMENT METHODS USING AI TO COPE WITH TODAYS AND FUTURE NVH CHALLENGES

摘要

With respect to future mobility scenarios, acoustic aspects of the brake systems will become more and more important. To avoid noise, the source itself - the hydraulic system and its functionality - and the entire transfer path - from the hydraulic unit to the driver's ear - are to be taken into account. A deep understanding of both and their impact on sound is necessary to cope with todays and future Noise, Vibration and Harshness (NVH) challenges. Here we use a multiple method approach by using e.g. model based engineering, simulation and a deep understanding of the forces transferred from the hydraulic unit to the chassis. All this helps to get a full understanding of the cause effect relationship within these complex systems. By knowing this, we can - together with our customer - frontload a good sound engineering from the very beginning of the development circle. If we are in need of a fast and efficient solution we learned, that by adding artificial intelligence, we reach faster and with less effort a good solution. This is especially interesting with respect to the transfer path in a vehicle.
