Question 8024
Regarding advanced driver assistance systems or ADAS, how does the LDW or "side assist" system work?
- It automatically maintains a constant distance from the vehicle traveling ahead.
- It alerts the driver when it detects a lane change caused by a distraction.
- It analyzes the objects ahead and, if there is a possibility of hitting a pedestrian, it brakes.
Show answer and explanation
Correct answer: It alerts the driver when it detects a lane change caused by a distraction.
LDW, which also appears on the exam as “side assist,” uses a camera to monitor lane markings. If you drift out of your lane without using your turn signal, for example because you're distracted, it treats this as an unintentional lane change and warns you with an indicator light, a sound, or a vibration. In the image, the head-up display highlights the left lane marking in yellow next to a vibrating steering wheel symbol. Maintaining the distance from the vehicle ahead is ACC's job.
