Integrated Braking Systems

IPGATE's patent estate covers the foundational technologies of modern electrohydraulic braking — from first-generation pressure-control concepts through second-generation pressure supply units to one-box brake-by-wire production integration. The portfolio extends into autonomous driving and centralized vehicle chassis control for SAE Level 3-5 applications.

From First Concept to Production Standard

IPGATE’s innovations span three distinct generations of integrated braking technology, each building on the last to advance pressure control precision, system integration, and fail-safe architecture.

Portfolio A · 2005 – 2012 · 2 sub-portfolios · 9 patent families

IBS Generation 1 — Pressure Control Foundations

Establishes the core architecture of integrated brake systems: piston pressure control (PPC), multiplexing valve control, fail-safe accumulator design, electrohydraulic brake booster, and the first 1-box brake-by-wire concept. Sub-portfolios A1 (IBS Basic) and A2 (IBS Premium) — 84 core innovations across 9 patent families.
