Microphone Array for Speaker Localization and Identification in Shared Autonomous Vehicles

With the current technological transformation in automotive industry, autonomous vehicles are getting closer to Society of Automative Engineers (SAE) automation level 5. This corresponds full vehicle automation, where driving system autonomously monitors and navigates environment. SAE-level 5, concept a Shared Autonomous Vehicle (SAV) will soon become reality mainstream. The main purpose an SAV is allow unrelated passengers share without driver/moderator inside shared space. However, ensure their safety well-being until they reach final destination, active monitoring all required. In this context, article presents microphone-based sensor that able localize sound events SAV. solution composed Micro-Electro-Mechanical System (MEMS) microphone array with circular geometry connected embedded processing platform resorts Field-Programmable Gate Array (FPGA) technology successfully process hardware localization algorithms.
