Better Understanding Factors of Impact on Brake System Corner Performance
Abstract:
The automotive industry continues to focus heavily on new electrified mobility strategies. Whether this electrified mobility consists of battery electric vehicles or electrified brake boost systems, there is a level of system sensitivity which presents new challenges throughout the industry during development of a new product. Most specifically in brake system development, much of the critical performance targets that have come along with electrification are cascaded down to the vehicle corner and its component performance. These corner level requirements have transformed to be more stringent in order to improve the overall system efficiency. It is important that the factors which lead to less than desirable performance are identified and understood. Some of the factors that influence the brake system corner performance are driven by multiple components, and this paper will go into identifying & explaining the following.
