LSP’s Leiber on the Future of Brake Systems

Dr. Thomas Leiber, chief executive officer of the engineering and development company LSP Innovative Automotive Systems GmbH, posted a short piece on Linkedin describing his thoughts about future brake-system developments. His predictions flowed from the recent, in his words, restructuring of the company’s intellectual property rights. This was his post:

In light of the realignment of our innovation and collaboration strategy of LSP Innovative Automotive Systems GmbH and IPGATE AG and interaction with my honorable father, I have restructured our intellectual property rights into different IP portfolios A, B, C, D and E and I dare to make some statements and predictions about the development of brake system and chassis control technology with three mainstreams:

#1: Vacuum booster technology will be replaced by 1-box braking systems and will reach vehicle equipment rates of 50% by 2nd generation 1-Box and 70% by 3rd generation 1-Box…. in time period between 2030 and 2035.

#2: 2-box braking systems such as iBooster + ESChev were initially ideal for HEV and the 1st generation of BEV vehicles, but are reaching their limits (limited regeneration, no real zero drag brake possible, limited to SAE AD level 2+, critical effects of failures) and will be replaced by X-Boost technology (www.idbc2.com, https://braketechnews.com/) designed in 2017 and published in ATZ extra article in 2019 with the ultimate goal of achieving SAE AD level 5 with three levels of redundancy. In the future, we will have fewer vehicles and the operating hours per vehicle will increase from currently only 4%. Therefore the availability and safety of a braking system in service will become more important than the unit cost of the braking system installed.

#3: Back in 2017 when filing the first patents, I had the vision that BEV vehicles and powerful central/domain computing will arrive, causing another paradigm shift in vehicle chassis control eventually disrupting the automotive supply chain, opening the door for new business models and Tier2 suppliers to enter the currently protected Tier1 market by offering smart actuators. Pressure actuators such as IBSe (https://lnkd.in/d9d_cNQ) first introduced into the race series Formula E, conceptionally designed for multi-channel brake torque control (https://lnkd.in/d3tFih-X) have significant cost advantages in comparison to electromechanical brake (EMB) and no relevant disadvantages as claimed by protagonists of EMB. This statement is yet to be explained and proven.
