Automotive lightweighting is one of the most important goals in automotive industry, energy strategy and environmental engineering, that helps reduce CO_2 emissions and improve fuel economy. The approaches of vehicle mass reduction focus on the design, optimization and analysis of structures, the application of lightweighting materials, advanced manufacturing technology, and et al. In this paper, we discuss in depth four key aspects of automotive lightweighting by collecting and analyzing data from Patent databases which involve Derwent Innovations Index, ProQuest Dialog and Chinese state intellectual property office. The discussion includes: 1) The current global situation, R & D trends and focus areas; 2) R & D direction among major countries and companies, as well as patent distribution; 3) Design optimization of structures, the application of lightweighting materials and the advanced manufacturing technology; 4) Analysis of patent value evaluation index for high-value and core patents in the automotive lightweighting field. |
