Zusammenfassung

The automotive sector is undergoing significant changes. Most of those are driven by stricter legislation and higher sensitivity of customers to environmental issues. Electrification of the powertrain is one of the key elements for OEMs to meet the strict CO₂ emission targets, especially in Europe. A mild hybridization with 48V systems can be a cost-efficient means to reduce CO₂ emissions. In addition, a 48V power supply system enables efficient electrification of other components like pumps and the usage of electrified air boosting devices to provide additional benefits.
The BorgWarner product portfolio does not only cover combustion engine technologies but includes products for every possible hybrid and electric vehicle configuration. Our claim in Corporate Advanced Engineering is to understand the operating strategies, benefits and potentials of each configuration to support our business units as well as our customers in their development process.
This is the motivation for developing a toolkit that enables us to make reliable predictions on fuel economy and performance and additionally allows us to analyze and understand potential benefits and where they originate from.
This toolkit, consisting of models, libraries and evaluation scripts can be used to derive requirements for future product generations or to configure demonstrator vehicles.
