The current massive changes in the electrification of vehicles are also causing a lot of new challenges for the foundation brake development.
New considerations and tools necessary, which allow the development of new techniques for the brake development processes.
Due to the heavy battery packages in BEV (battery electric vehicle), the GVW (gross vehicle weight) increases, which requires larger brake systems. But at the same time, due to the kinetic energy recuperation, the usage of the foundation brake decreases significantly.
The effects to the braking system are varied, due to the different blending algorithms, which are available from car manufacturer to car manufacturer and even vary from vehicle to vehicle.
The topic of this paper is to address this problem. The aim is to develop new approaches and testing techniques for standard brake shaft dynamometers to consider all those effects and make the dyno much smarter in order to close the gap between dyno-level and vehicle-level tests.
The implementation of a real time HiL (hardware in the loop) system into the dyno would allow users to simulate different vehicle components models, which typically impact the brake in real vehicles and allow new maneuvers and brake applications.
As a results this approach, a wider variety of brake maneuvers could be simulated. Maneuver variations could be based on tire models, road surface models, battery management models, etc.
The complexity of the electric vehicle transition has presented the need to established this project to ensure that all new challenges in regards of to brake testing are considered sufficiently in the future.
The above described is an addition in the ALPHA project, which is a consortium of some European vehicle manufacturers, brake system suppliers, test equipment manufacturers, and vehicle simulation providers.
