Abstract—The paper aims to present the application of fuzzy logic to correct distances obtained from the UWB system. Positioning using the Ultra-Wideband (UWB) system for nautomotive purposes has many applications (including support for Advanced Driver-Assistance Systems (ADAS) applications in making driving decisions more safe and comfortable). Based on the research carried out by the authors of the article, it appears that the data maintain high precision in certain ranges, but they depend on the many factors like environment, obstacles and the distance in which the positioned objects are located. By using data fusion using fuzzy logic, it is possible to improve the distance value of the UWB system as presented in this article. The result of the research and the proposed correction is the receipt of a wireless system enabling the determination of distances with accuracy to centimeters for a large range of distances.
Index Terms—Fuzzy Logic, lidar, localization, ultra-wideband
