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.
