Analysis of JTEKT's Patent Layout for Steer-by-Wire and its Enlightenment to China's Automotive Industry

Abstract

Against the backdrop of the rapid iteration of intelligent connected vehicles and autonomous driving technologies, Steer-by-Wire (SBW) has become the core technical direction for the upgrading of automotive steering systems. As a global leader in the electric power steering sector, as well as a pioneer and mass-production promoter of SBW technology, JTEKT has laid out a large number of core patents worldwide, forming significant technological barriers and intellectual property advantages. Based on global SBW patent data, this paper combs the technical architecture, analyzes the patent application trends, and dissects the competitive landscape of major applicants. It focuses on the patent application status, subdivided technical layout characteristics, and technological route evolution of JTEKT in the SBW field, summarizes its patent layout strategy and core technical advantages, and puts forward targeted suggestions for technological R&D and patent layout combined with the current situation of China's automotive industry, so as to provide a reference for domestic automakers and component enterprises to break through foreign technological blockades and achieve independent control of SBW technology.
