DENSO has developed a new vision sensor that detects pedestrians, cyclists, road signs, driving lanes and other road users 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.

It improves night vision by using a unique lens specifically designed for low-light use, and a solid-state imaging device with higher sensitivity. 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% size reduction from previous models reduces costs and makes installation easier.
