Detection of vulnerable road users in blind spots through Bluetooth Low Energy

摘要

Around a vehicle, a blind spot is an area, which cannot be seen by the driver. Blind spot accidents are a frequently occurring problem. Annually, dozens of deaths are caused by this phenomenon despite legally compulsory prevention tools and large investments in raising awareness and developing prevention systems. Because this is not enough to reduce the number of accidents, proactive solutions must be found. This article describes the evaluation of a new blind spot system based on BLE (Bluetooth Low Energy). In this paper, a complete system is designed with on-the-shelf products and finally realized in a proof-of-concept. The final design requirements are fixed, by figuring out where the blind spots are and which various advantages and disadvantages the existing systems have. In a further stage, the system is tested in several possible critical situations, proving that it is very robust. Vulnerable road users are indeed detected by visualization on the LCD display.
