KARIYA, Japan, Nov. 20, 2012 /PRNewswire/ --DENSO Corporation has developed a
new and higher-performing millimeter-wave radar that has a longer and wider
detection range, which helps improve the responsiveness of an active safety
technology, such as Pre-crash Safety (PCS) and Adaptive Cruise Control (ACC)
systems. DENSO's new, multi-zone radar is significantly lower in cost due to
an improved material selection and also is approximately the same size as the
company's previous model. The new millimeter-wave radar system is available as
a factory option on the Mazda6, which launched first in North America and then
in Japan, Europe and other regions this past fall.

"For enhanced performance, in addition to the longer detection range, the
radar's wider detection area improves the systems response in lane-intrusion
situations," said Ron Schubert, Director Body Control Systems at DENSO
International America, Inc. "The wider radar detection is especially important
in the United States where we are a nation of multiple lane highways."

Achieving a Higher and Wider Detection Angle
DENSO's new radar has a detection distance of 205 meters and a +/- 18 degree
detection radius within a distance of 35 meters from the vehicle. This is
compared to 151 meters and +/- 10 degreesin the conventional product.

To achieve a longer detection distance, DENSO improved the electronic circuit
design in a way that reduces electromagnetic interference that could limit the
receiver's detection of reflected radio waves. This allows the sensor to have
an enhanced receiving ability for objects at a longer distance. This longer
detection range enables ACC-equipped vehicles to maintain a safe and constant
distance to the vehicles in front of them – even when traveling at higher
speeds. Also, by better positioning the receiving antenna, the radar has a
wider detection angle, which improves system responsiveness.

In addition, to improve manufacturing efficiency a motor was installed in the
sensor to automatically adjust the antenna's axis, which was done by hand in
the previous version.

In an effort to realize an accident-free automotive society, DENSO has
developed and commercialized both passive and active safety technologies to
protect vehicle occupants, as well as to prevent traffic accidents. Based on
the technologies it has developed, DENSO will continue toward a safe and
reliable automotive society for all people in the world, including drivers and

DENSO will progressively make the new millimeter wave radar system available
for a greater number of vehicle models across the globe.
