SYSTEM DESCRIPTION
LANE DEPARTURE ALERT SYSTEM DESCRIPTION
(a) The lane departure alert system is a system which uses the forward recognition camera to recognize and determine the lane and the position of the vehicle when the vehicle is being driven on highways and other roads with white (yellow) lines. Based on the situation, this system provides information and warnings for the driver.
SYSTEM SPECIFICATION
Operation speed |
Approximately 50 km/h (32 mph) or more. |
Operation lane width |
Approximately 3 m (10 ft.) or more. |
Operation curve radius |
Approximately 150 m (493 ft.) or more. |
OPERATING CONDITIONS
(a) Lane departure alert function can operate if all of the following base conditions are met:
(b) Vehicle sway warning can operate if all of the following base conditions are met:
CONTROL OF EACH FUNCTION
(a) Lane departure alert function:
(1) Sensitivity: "Standard (graphic display)"
A warning is output when a front wheel starts to cross a lane marker.
HINT:
When the deviation speed (lateral travel speed) is slow, the warning may be output after the front wheel crosses over the lane marker.
(2) Sensitivity: "High (graphic display)"
A warning is provided when a front wheel nears a lane marker.
HINT:
When the deviation speed (lateral travel speed) is slow, the warning may be provided when the front wheel starts to cross the lane marker.
(b) Vehicle sway warning:
(1) A warning is output when any of the following occurs:
