Technology trends related to automatic adjustment of headlamp directional illumination
Study of patent applications submitted by Koito, Hella, Hyundai Mobis, Daimler, and Stanley Electric
This report created by MarkLines focuses on a number of technical topics surrounding the automotive industry, and is based on patent information obtained from the "Technical Information Distribution Service-swimy" information service provided by Toyota Technical Development Corp. (TTDC). The two business areas of TTDC are in the fields of intellectual property (IP) and measurement control solutions. The intellectual property (IP) side of TTDC is involved in the collection and analysis of information on automotive technology developments globally, and provides services such as consulting for research planning, applying for patents in foreign languages, and technical translation.
This report describes the trends of patent applications, by company, regarding technologies related to the automatic adjustment of headlamp directional illumination.
Following the trend of an increasing number of patent applications concerning automatic adjustment of headlamp directional illumination between 2010 and 2012, there was a temporary decrease, but since 2014 there is again a trend in the increasing number of applications. The companies submitting a large number of patent applications include Koito Manufacturing Co. Ltd (Koito), Hella KGaA Hueck & Co. (Hella KGaA Hueck), Hyundai Mobis Co., Ltd. (Hyundai Mobis), Daimler AG (Daimler), and Stanley Electric Co., Ltd. (Stanley Electric).
Focusing on the development items among the applicants submitting a large number of patent applications, the most applications have been submitted by Koito for “Vehicle lamp control device (Development Group 1)”; by Hella KGaA Hueck for “Method for controlling positioning velocity of vertical light-dark boundary relative to light function of object in vehicle, involves adjusting positioning velocity of vertical light-dark boundary to determined rate of change of object “; by Hyundai Mobis for “Control method of a vehicle lamp”; by Daimler for “Method for controlling external light distribution of vehicle e.g. bus, involves enabling deviation from driving light distribution hazard light distribution, while driving predetermined range, when predetermined range is descended”; and by Stanley Electric for “Lighting control device for vehicle headlamps, vehicle headlamp system (Development Group 1)”.
