About EyeSight
The characteristics of the stereo camera are similar to those of human
eyes. For this reason, conditions that make it difficult for the driver to see
in the forward direction have the same effect on the stereo camera. They
also make it difficult for the system to detect vehicles, obstacles, and traf-
fic lanes.
Detection by the EyeSight system is limited to objects that are within the
range of the stereo camera's field of view. Also, after an object enters the
range of the camera's field of view, it may take some time for the system
to detect it as a controllable target and to warn the driver.
Low objects surrounding the vehicle
cannot be detected.
Under the conditions listed below, it will become more difficult for the sys-
tem to detect the vehicle in front, motorcycles, bicycles, pedestrians and
obstacles on the road, and lane markers. Also, EyeSight may temporarily
stop operating. However, the temporary stop will be canceled once these
conditions have improved and the vehicle is driven for a short period of
time.
- Bad weather (for example heavy rain, a blizzard or thick fog). In particu-
lar, the system is more likely to temporarily stop operating when there is
an oil film adhering to the windshield, a glass coating has been applied,
or poorly performing wipers are used.)
- When affected by strong light from the front (sunlight or headlight beams
of oncoming traffic, etc.)
- When the windshield washer is being used.
- When raindrops, water drops, or dirt on the windshield are not wiped off
sufficiently
- The windshield has become fogged, or snow, dirt, dust or frost has
adhered to it, reducing the stereo camera's field of view.
- The vehicle is tilted at an extreme angle due to loaded cargo or other
factors.
- When visibility is poor due to sand, smoke or water vapor in the air, or
when the vehicle in front or oncoming traffic causes water, snow, dirt or
other substances to obscure the view
