Lane Departure Warning Plus

Haptic Lane Departure Warning Plus (LDW+)  - This system is an available option offered on vehicles equipped with Electric Power Steering (EPS) and the Forward Facing Camera Module (FFCM). The system can be turned ON or OFF with a single hard button in the Integrated Center Stack (ICS) below the Uconnect® display. The LED on the button will inform the driver of the system status when the driver is not on the Drive Assist screen. The system operates when enabled above 60 km/h (37 mph) and below 180 km/h (112 mph).

The LDW+ system issues a warning alert to the driver in case of an unintended lane departure (for example, the driver did not use turn signals beforehand to confirm a planned lane change). The LDW+ system uses the FFCM to detect lane markings and measure vehicle position within those lane boundaries. The warning can be visual or haptic feedback to the driver, for example through a vibration in the steering wheel that feels like a virtual "rumble strip" induced by the Electric Power Steering (EPS) system. If the driver continues to unintentionally drift out of the lane, the system provides a visual warning to prompt the driver to adjust the vehicle's trajectory to remain within the lane boundaries. When only a single lane marking is detected and the driver unintentionally drifts across the lane marking (again, no turn signal), the LDW+ system provides a visual warning through the instrument cluster to prompt the driver to remain within the lane. When only a single lane marking is detected, as haptic warning will not be provided. The driver may manually override the haptic warning by applying torque into the steering wheel at any time. The use of the turn signal suppresses the warning.

No Hands Recognition Strategy  - When operating conditions have been met, the LDW+ system will employ a "No Hands Recognition Strategy". The system monitors the torque sensor inside the EPS to verify the driver's hands remain on the wheel. If the hands are not detected, this will cause an audible warning to the driver consisting of left front and right front chimes as well as displaying a visual warning message. The strategy will cancel LDW+ activation if the driver does not return their hands to the wheel.

The driver can configure the torque feedback amount and warning zone start point through personalization settings in the Radio. Three settings for each are provided.

The LDW+ system will indicate the current lane drift condition through the Electronic Vehicle Information Center (EVIC). When the LDW+ system is ON, the lane lines are gray when the lane boundaries have not been detected and the LDW+ indicator is solid white.

Changing LDW+ Status: 

When in the Safety & Driving Assistance screen, the customer can configure the intensity of the torque warning and the warning zone sensitivity (early/late) through the personalization settings.

1. Press the "Controls" button on touchscreen located on the bottom of the Uconnect® display.
2. Press the "Settings" button.
3. Press the "Safety & Driving Assistance" button.

Personalization Settings: 

• The LDW+ system can be enabled/disabled via an ON/OFF switch with indicator (indicator ON when system is OFF). The indicator will remain ON when a fault is detected in the LDW+ system.
• The LDW+ system retains the last system state (enabled or disabled) from the last ignition cycle when the ignition is changed to the ON/RUN position.
• The LDW+ system has a lane warning sensitivity setting to adjust earliest to latest haptic feedback warning levels (for example, early, medium, late) located within the personalization settings.
• The LDW+ system retains the last lane warning sensitivity setting from the last ignition cycle when the ignition is changed to the ON/RUN position.
• The LDW+ system has a torque intensity setting to adjust the torque level (for example, low, medium, high) of the haptic warning located within the personalization settings.
• The LDW+ lane sensitivity and torque intensity settings will not be locked out during driving.

LDW Warning Message: 

• Driver Information Display (DID) Screen 

  - When the LDW+ system is ON; the lane lines are gray when both of the lane boundaries have not been detected and the LDW+ indicator is solid white.

• Left Lane Departure - Only Left Lane Detected 

  - When the LDW+ system is ON, the LDW+ indicator is solid white when only the left lane marking has been detected and the system is ready to provide visual warnings in the DID if an unintentional lane departure occurs. When the LDW+ system senses the lane has been approached and is in a lane departure situation, the left thick lane line flashes yellow (ON/OFF), the left thin line remains solid yellow and the LDW+ indicator changes from solid white to flashing yellow.

• Lane Approached (Flashing Yellow Thick Line, Solid Yellow Thin Line/Flashing Yellow Indicator)  - When the LDW+ system is ON, the lane lines turn from gray to white to indicate that both of the lane markings have been detected. The LDW+ indicator is solid green when both lane markings have been detected and the system is "armed" to provide visual warnings in the DID and a torque warning in the steering wheel if an unintentional lane departure occurs.
• Lanes Sensed (White Lines/Green Indicator)  - When the LDW+ system senses a lane drift situation, the left thick lane line and left thin line turn solid yellow. The LDW+ indicator changes from solid green to solid yellow. At this time torque is applied to the steering wheel in the opposite direction of the lane boundary.
• Lane Sensed (Solid Yellow Thick Line, Solid Yellow Thin Line/Solid Yellow Indicator)  - When the LDW+ system senses the lane has been approached and is in a lane departure situation, the left thick lane line flashes yellow (ON/OFF) and the left thin line remains solid yellow. The LDW+ indicator changes from solid yellow to flashing yellow. At this time torque is applied to the steering wheel in the opposite direction of the lane boundary.
