DENSO develops standard vision sensor

DENSO Corporation has developed a standard vision sensor that detects pedestrians at night, cyclists, road signs, driving lanes and other road users. The sensor is featured in the 2018 Toyota Alphard and Vellfire, which were released in January this year.

The vision sensor works in conjunction with a millimeter-wave radar sensor and allows automobiles to automatically activate emergency braking when obstacles are identified, helping reduce accidents and improve overall vehicle safety.

The night vision sensor uses 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% size reduction from previous models reduces costs and makes installation easier.
