What is the effective working speed range for LKA Lane Keeping Assist System?
2 Answers
LKA Lane Keeping Assist System only activates when the vehicle speed reaches 65km/h or above. Relevant details are as follows: 1. Definition: As part of intelligent driving assistance systems, Lane Keeping Assist builds upon Lane Departure Warning System (LDWS) by controlling the steering system to help maintain lane discipline. It utilizes a camera to identify lane markings and supports keeping the vehicle within its lane. 2. Function: If the vehicle approaches detected lane markings with potential departure risk, it alerts the driver through steering wheel vibration or audible warnings while making minor steering corrections to maintain proper lane position. If no driver intervention is detected over an extended period, the system issues an alarm to prompt driver awareness.
I've repaired many cars and understand how the Lane Keeping Assist System works. It is most effective at speeds between approximately 60 to 140 km/h because the system relies on cameras to identify lane markings. At speeds too low, such as below 50 km/h, the images are too slow and may lead to misjudgments. At speeds too high, such as exceeding 150 km/h, the images become blurry, and the system may shut off to prevent errors. The minimum activation speed is typically 60 to 70 km/h, depending on the car model—systems from brands like Volkswagen and Honda vary. During high-speed driving, it can automatically correct minor deviations, but it becomes ineffective if driving too slowly or too fast. I recommend car owners check their manuals to confirm the specific range and experience its assistance on highways. Regular maintenance of the sensors is also crucial to ensure accurate operation.
