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