Kia Sorento: Description

Kia Sorento (XM, 2011-2015) Service Manual / Body Electrical System / Lane Departure Warning System (LDWS) / Description

System Operation

Typically, lane departure warning is activated at a speed over 60 km, but suppressed in case of unintentional lane departure when driver do not operate turn signal.

System Operation Conditions

User Conditions

(1)	When unintended lane departure is occured, warnings are generated.

(2)	When driver operates a turn signal for lane departure, no warnings are generated.

(3)	When driver operates wiper, no warnings are generated according to operating coditions (Wiper High)

Vehicle Conditions

(1)	When the accelerated velocity of vehicle exceeds certain speed, LDW system is activated.

(2)	When a turn signal is not used. LDW system activates.

(3)	LDWS system is not activated when wipe motor speed is more than 45 RPM, even if the vehicle is equipped with rain sensor.

Lane Conditions

(1)	lanes are visible and recognizable , LDWS can be on normal operation mode.

(2)	Operate on all roads, including highways, country roads and urban freeways at a speed of 60 km/h and from 2.7 to 5.0 meters of lane width.

(3)	Lane material: asphalt roads, concreat roads

(4)	Lane color: White, Yellow, Blue,

(5)	Temporary lane marker for repairing road

(6)	lanes are visible and recognizable, LDWS can be on normal operation mode independent of season or time,

(7)	Operate under partially visible lane markers such as and regardless of inclement weather, including rain and wet roads, and time limit

(8)	Be performed in a curve of radius 250 meters

Lane Departure Warning

This lane Departure Warning Algorithm is for HKMC whole vehicle that will apply to LDWS

Lane departure warning start speed: 60KPH

(1)	Warning Start Speed: 60KPH

(2)	Warning Stop Speed: 55KPH

To prevent repetation of system warning on and off according to vehicle speed variation, This specification establish warning stop speed as 55 KPH for hystheresis characteristic.

Lane Recognition Standard Speed : 40KPH

(1)	Lane recognition start speed : 40KPH Lane recognition is started at 40KPH less than warning start speed to minimize recognition time after vehicle is drived into lane.

(2)	Lane recognition stop speed: 35KPH Lane recognition stop speed is setted 35KPH with hysteresis to avoid repetition of lane recognition on and off.
