DENSO Corp. has developed a new standard vision sensor that detects pedestrians, cyclists, road signs, driving lanes and other road users that are difficult to see at night. Working in conjunction with a millimeter-wave radar sensor, the new vision sensor allows automobiles to automatically activate emergency braking when obstacles are identified, helping reduce accidents and improve overall vehicle safety. It is featured in the 2018 Toyota Alphard and Vellfire, which were released in January this year.
The new sensor illustrates how DENSO supports the widespread adoption of safety technologies that will play a critical role in the advancement of future mobility, according to the company. It improves night vision by using a unique lens specifically designed for low-light use, and a solid-state imaging device with higher sensitivity. These innovations help the sensor better identify other road users and different-shaped road signs, such as triangular, rectangular and octagonal signs used in Japan, Europe and the United States. An improved white-line detection algorithm and road-edge detection algorithm also broaden the operating range of lane-keeping assistance and lane departure alert functions, while a 40 percent size reduction from previous models reduces costs and makes installation easier.
DENSO has been developing technologies and products to help create a society free from traffic accidents. The company says these technologies support its continued pursuit to deliver a safe and secure automotive society for all people around the world.
