Fusion Sensor for Driving Assistance System

The development of driving assistance systems that improve automobile convenience and safety is being promoted throughout the world, primarily by automobile manufacturers. One such system is the Adaptive Cruise Control (ACC) System, which controls the vehicle speed and maintains a safe head-up distance while driving at high speeds. The ACC has been installed in luxury cars, and its recognition capabilities have been improved. This system makes use of state-of-the-art sensing technologies such as laser radar and millimeter-wave radar. With the aim of creating a "Driving Support System for Congested Traffic" as a next-generation driving assistance system, we have developed a "fusion sensor" as an optimal sensor for this system by blending millimeter-wave radar with an image recognition sensor. This sensor achieves both distance and angle accuracy, which an independent sensor cannot achieve. We manufactured a test vehicle that was equipped with the Driving Support System for Congested Traffic and fusion sensor, and were thus able to verify the sensor's practical use. This report will introduce the Driving Support System for Congested Traffic and fusion sensor that we have conceived.
