Bosch and Sony Semiconductor
Solutions have agreed to cooperate with the aim to develop a highly innovative
camera technology that will enable cars to reliably sense their surroundings
even in difficult lighting conditions.
Difficult lighting conditions
can arise out of different conditions. One can be suddenly dazzled with your
vision getting restricted. This is something drivers experience regularly when
driving on a sunny day when the sun is low in the sky. Briefly driving blind is
often also required due to the glare when driving out of a tunnel on a bright
day. Changing or poor lighting conditions provide a challenge not only for the
human eye, but also for video sensors such as those required for driver assistance
systems and automated driving.
"Bosch and Sony
Semiconductor Solutions are bringing together the technological know-how of the
market leader for image sensors and the automotive know-how of the world's
biggest supplier," says Gerhard Steiger, president of the Bosch Chassis
Systems Control division.
Along with radar and
ultrasonic sensors, video sensors are the sensory organs of modern cars. To
create driver assistance systems, such as automatic emergency braking for
pedestrians, lane keeping support systems, and road sign recognition, cameras
are becoming increasingly integral to modern vehicle models. The advantage of
video sensors is that they can detect objects and the images produced have a
huge information density.
For many years, Bosch has been
producing video sensors in mono and stereo technology to provide a360 degree
all-round view, and is one of the leading suppliers in this sector of the
automotive industry. In the future, video sensors will be a crucial component
of the sensor concept for automated driving. This requires cameras that operate
reliably when there is a sudden change of lighting conditions from dark to
light and vice versa. In addition, they must be able to instantaneously
differentiate when there are drastic differences in brightness within a shot.
"Automated driving cars will only be safe on the road if they can
accurately sense their surroundings at all times," says Steiger.
