Lane Departure Warning System: Description
WARNING: This page is about a different car, the 2020 Jeep Renegade. However, it is still accessible from the selected car via links, so may be relevant.
By means of a video sensor mounted behind the rear view mirror and in contact with the windshield, the Lane Departure Warning Plus (LDW+) system is able to detect the lines on the road and keep the vehicle on its own lane preventing involuntary lane changes.
If the vehicle starts to drift into another lane and the driver, having their hands on the steering wheel, does not use the direction indicator, the system alerts the driver that the vehicle is going to depart from the lane through two feedbacks: a visual indication on the instrument panel and a haptic signal by applying a torque on the steering wheel.
Details below:
- The system uses a camera-based sensor to detect and measure the position of the vehicle within the borders of the lane.
- During a drift towards another lane (direction indicator not active), the system will provide a visual warning and a haptic warning by applying a torque to the Electric Power Steering (EPS) system.
- The system checks if the driver's hands are on the steering wheel; if they are not present the system provides a warning to induce the driver to position them. The system is deactivated if the driver does not place their hands on the steering wheel within 5 seconds.
- The system can be partially activated or deactivated via a button located in the switch pod. The LED on the switch pod will inform the driver on system status.
- The driver can configure the amount of torque applied to the steering wheel as a feedback and the distance from the area where the visual warning will start using the radio customization settings.
- When activated, the system works at speeds higher than 60 km/h (37 mph) and lower than 180 km/h (110 mph).
- The driver can bypass the system in different ways, including: use of direction indicators, torque applied by the driver higher than that applied by the EPS system.
- The system is deactivated automatically when a safety system such as Antilock Brake System (ABS), Traction Control System (TCS), Electronic Stability Control (ESC), Forward Collision Warning (FCW) etc. is activated.
