Wireless Bluetooth Car Collision Detection System
Yuying Wang, Kaixuan Hu, Ya Zhou · 2019
In view of the increasing serious road traffic accidents and the frequent rear-end collisions of motor vehicles, a car collision prevention and early warning system based on wireless Bluetooth technology is proposed. The system is divided into three modules: main control, ranging and Android mobile phone terminal program. The results show that when driving at low speed, the ranging error is 0 ~ 10cm, which is the same as the radar ranging error, the acoustic-optical alarm and the real-time display of distance can better remind the driver to control the vehicle distance, so as to avoid rear-end collision when following up at low speed, backward collision when reversing and side collision caused by blind area. Custom alarm distance parameter setting, receiving distance information transmitted by the main control end real-time display, suitable for ordinary household car wireless car collision alarm. The warning installation of acousto-optic system extends the visual and sensory functions of drivers and plays an active role in early warning for improving road traffic safety.
