NVH has always been an important performance parameter for Automotive requirements, both from comfort standpoint as well as regulatory perspective. Over the years, lots of refinement has happened in a vehicle in NVH field, especially in the powertrain, vehicle structure, aerodynamic and tyre side. However, the customer sensitivity and expectations have only increased and even a slight discomfort from lesser contributing sources like mechatronic systems, which are increasingly getting commoditized with the introduction of newer safety regulations, have potential to create annoyance for the customer. The objective of this work is to investigate and subsequently mitigate the noise issues emanating from a small mechatronic brake system, using experimental (objective and subjective testing) and numerical modelling approaches. The paper highlights the details, which goes into identification of systemic root causes and how design corrections (including software changes) could lead to increased comfort for the rider and meet future safety regulatory requirements, which are only going to get stringent, with more and more electric vehicles populating the market.
