A Study on Optimization of Brake Feeling and Method for Flexible Brake with Integrated Electronic Booster

Throughout the automotive industry, the application of an integrated electronic booster (IEB) system has been actively applied following with diversify powertrain types and expand autonomous vehicles.[1, 2] Compared to the existing vacuum boosters, the performance advantages of IEB are 1) robustness against environmental changes, 2) rapid hydraulic reactivity, etc., and the advantages of cost / university are 1) flexibility for powertrain changes 2) weight saving 3) package simplification. Although IEB has a great advantage in performance and cost, it still needs a lot of research in various fields to realize the braking feeling, which is the performance of the emotional aspect, similar to the existing system.
