\n
\n
On-coming vehicle recognition function<\/div>\n<\/dd>\n<\/dl>\n
\n
\n
\u2022 The forward sensing camera (FSC) recognizes a light-emitting object which meets any of the following conditions and is at least within 600 m {1,968 ft 6 in}<\/span> from the monitoring vehicle as an on-coming vehicle.<\/div>\n

\n
\n
Note<\/div>\n<\/dd>\n
\n
\n
\u2022 If the on-coming vehicle and the surrounding conditions are as follows, the forward sensing camera (FSC) may require time until it recognizes an on-coming vehicle.<\/div>\n
\n
\n

\n
\n
\u2015 Red light emitted from light-emitting object is detected<\/div>\n
\u2015 Determines that there is a pair of light-emitting objects<\/p>\n
\n
\n
Note<\/div>\n<\/dd>\n
\n
\n
\u2022 If visibility is poor, the system could recognize reflecting objects on the road surface or a guard rail as a vehicle ahead.<\/div>\n
\u2022 If visibility is poor due to rain or fog, the system may not recognize a vehicle ahead even though one may exist.<\/div>\n<\/div>\n<\/dd>\n<\/dl>\n\n\n\n

Town\/city streets recognition function<\/div>\n
\u2022 In the following cases, the forward sensing camera recognizes that the vehicle is traveling on town\/city streets.<\/div>\n
\n
\n
\u2015 Several light-emitting objects of certain height or more from road surface along same line are detected<\/div>\n
\u2015 Camera image gray color is certain level or more<\/p>\n
\n
\n
Note<\/div>\n<\/dd>\n
\n
\u2022 Even during travel other than on town\/city streets at night, if the road surface is bright from moonlight, the system may recognize that the vehicle is traveling on town\/city streets.<\/div>\n<\/dd>\n<\/dl>\n\n\n\n

Vehicle lane lines and travel lane recognition function<\/p>\n

\n
\n
\u2022 The forward sensing camera (FSC) recognizes lineal objects which are white\/yellow and paler than the surrounding color as vehicle lane lines by the contrast (color density) of the camera image.<\/div>\n
\u2022 If the vehicle lane lines are continuous they are recognized as actual lines and if discontinuous they are recognized as broken lines.<\/div>\n
\u2022 The travel lanes recognized from the vehicle lane lines on the left and right of the vehicle are used to calculate the width.<\/div>\n
\u2022 Traveling in a straight line or cornering is determined by the status of the vehicle lane lines.<\/p>\n\n\n\n

Aiming correction function<\/p>\n

\n
\n
\u2022 The forward sensing camera (FSC) adjusts the camera shot angle by aiming, and stores the vanishing point *1<\/sup>. The stored vanishing point and the current vanishing point are compared and if there is a deviation of a certain value or more in the vanishing point, the current vanishing point is stored as the new vanishing point.<\/div>\n<\/dd>\n<\/dl>\n
*1 :The vehicle lane lines on the road surface are parallel and do not intersect, however, when viewed by the camera image, the lines converge in the distance and eventually cross. The point at which the lines cross is called the vanishing point.<\/div>\n\n\n\n

On-board diagnostic function<\/p>\n

\n
\n
\u2022 The forward sensing camera (FSC) detects internal malfunctions and outputs DTCs. Regarding dirt and fogging of the camera lens and windshield glass and FSC communication errors, the body control module (BCM) outputs DTCs based on the signal from FSC.<\/div>\n<\/dd>\n<\/dl>\n



\n<\/a><\/p>\n

Construction<\/p>\n

\u2022 The forward sensing camera (FSC) is positioned on the windshield.<\/div>\n

\n
\n
\u2022 The forward sensing camera (FSC) shoots in the following range.<\/div>\n<\/dd>\n<\/dl>\n
\n
\n
Note<\/div>\n<\/dd>\n
\n
