Lane Departure Warning, Important Safety Features for Wuling Cars
30 June, 2023
One topic that will always be relevant for discussion about vehicles, especially cars, is their safety features that can help drivers and passengers drive more safely. One of the car products that prioritizes driver safety is Wuling with a safety and security supporting technology called the Advanced Driver Assistance System (ADAS). This technology has a wide range of feature options, one of which is Lane Departure Warning (LDW). What is the meaning of the Lane Departure Warning feature?
Lane Departure Warning or LDW is a security support feature on Wuling vehicles that uses sensors to monitor the vehicle’s position whether it deviates from the safe limits of lane markings or not. The main purpose of this feature is to warn the driver when the vehicle leaves the lane unexpectedly.
How Lane Departure Warning Works
How the LDW feature works can be described in the following points:
- The LDW system continuously monitors road markings using sensors in the form of cameras placed on the top of the windshield. This sensor captures an image of the road markings, which becomes a reference point for determining the car’s position.
- The data captured by the sensor is then processed by the LDW system software. The LDW system will analyze road markings and identify lane boundaries. This allows the system to establish the base position of the car within the detected path.
- When the car is moving, the LDW system will track the car’s position relative to the road markings. Then, the system will compare the trajectory and alignment of the car with the previously recognized lane boundaries.
- If the LDW system detects that the car is deviating from the lane without activating the turn signal, the system will consider it a potential for the car to go off the lane unexpectedly. The specific criteria for determining a car off the track involves various factors, such as the duration and magnitude of the car’s deviation.
- Once the car is detected to have accidentally left the lane, the LDW system will automatically warn the driver. This alert will be visible on the instrument cluster and accompanied by an audible alert. This warning aims to make the driver immediately control the car to get back on track.
- After receiving a warning from the LDW system, the driver is expected to take corrective action by directing the car back to the right lane or activating the turn signal when changing lanes.
What Conditions Make Lane Departure Warning Work?
Lane Departure Warning works when the car is traveling at speeds between 60-180 km/hour. In addition, this system will also work when the driver leaves the lane without turning on the turn signal, so that it is considered an unwanted lane deviation. In addition, the LDW system will also work normally if the road marking lines are clearly visible so that the sensor camera can capture the road markings properly.
However, there are several external conditions that can interfere with the LDW system to work normally due to the closed camera sensor so that the camera cannot capture clear images. These external conditions include the following:
- Extreme weather, such as heavy rain, storms, snow, hail, or smog
- The presence of foreign objects such as piles of dirt and dust blocking the view of the camera
- Road marking lines that are not clearly visible due to road damage, snow piles, or puddles
- Sharp turns or narrow roads (lane width less than 2.5 m) or lanes that are too wide
- There are shocks that make the car sway hard
- There are more than two lane lines on the left and right of the lane
- The number of paths increases or decreases, or the lines of the path are complicated to traverse
These factors can interfere with or cover the camera sensor in the LDW system which can affect the performance of the LDW system. Therefore, before driving, make sure you are always aware of external things that can interfere with the car’s security system to function optimally.
With the Lane Departure Warning security system, the driver is helped to remain aware and understand the position of the car on the road. LDW can also help the driver to assess the traffic situation and respond actively, thereby reducing the risk of an accident. Lane Departure Warning can also reduce the risk of a car crashing or being hit by another vehicle, as well as hitting a road divider due to a sudden or unreasonable exit from the lane.
However, the driver must always be vigilant and responsible when driving to avoid unwanted hazards. Drivers are expected to always be careful and aware when driving because external disturbances sometimes occur which prevent the car’s security system from operating normally.
In addition, drivers are also not allowed to normalize driving when they are not focused or when they are drowsy. It is better if the driver feels that he cannot drive with focus due to drowsiness or other reasons, immediately pull over to the nearest rest area to rest for a while. Drivers can continue their journey when they are refreshed and more focused on driving
This is an explanation of the Lane Departure Warning safety system on Wuling vehicles. Apart from LDW, there are many other safety features on Wuling vehicles that can help drivers drive safely and safely.
