Denso launches vision sensor for improved night driving safety

Japan-based Denso has developed a new standard vision sensor that aims to detect pedestrians at night, cyclists, road signs, driving lanes and other road users. It works with a millimetre-wave radar sensor, enabling automobiles to activate emergency braking when obstacles are identified to help reduce accidents and improve safety.

Japan-based Denso has developed a new standard vision sensor that aims to detect pedestrians at night, cyclists, road signs, driving lanes and other road users. It works with a millimetre-wave radar sensor, enabling automobiles to activate emergency braking when obstacles are identified to help reduce accidents and improve safety.


The solution uses a lens specifically designed for low-light use and a solid state imaging device with higher sensitivity to 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 are also said to broaden the operating range of lane-keeping assistance and lane departure alert functions, while a 40% size reduction from previous models aims to reduce costs and make installation easier.

    David Crawford investigates progress in a key safety area - work zones. Highway construction zone safety is taken seriously enough in the US to merit a special spring National Work Zone Awareness Week, which in 2010 ran from 19-23 April. Headed by the US Department of Transportation's Federal Highway Administration (FHWA), this aims to reduce an annual toll of work zone deaths - 720 in 2008 (an average of one every 10 hours) with more than 40,000 traffic injuries (an average of one every 13 minutes).

The competitive nature of the car market has seen an increase in protection for those travelling inside the vehicle and this is reflected in the casualty statistics -but the same does not apply to those outside the vehicle. And with current societal trends such as ageing populations, an increasing number of pedestrians and cyclists encouraged by environmental policies, this is an area that authorities such as the European Uni
