What do ACC and LKAS mean?

[RobertMarie]

ACC refers to the Adaptive Cruise Control system, and LKAS refers to the Lane Keeping Assist System. When these two words appear on the dashboard, it indicates that the corresponding systems are activated. Both ACC and LKAS functions can have a certain impact on actual driving, so in some road conditions, it is more appropriate to turn them off. ACC is more intelligent compared to traditional cruise control systems. Its function is to monitor the vehicle ahead through radar sensors, digital processors, and control modules. When the vehicle ahead slows down, the car automatically brakes to reduce speed. When the distance to the vehicle ahead increases, it accelerates automatically, always maintaining a reasonable safe distance. The role of LKAS is to prevent the vehicle from deviating from its lane. When the vehicle drifts out of the driving lane, the system alerts the driver through a warning, prompting the driver to consciously maintain the vehicle within the lane. LKAS can be used as long as the vehicle speed is above 65 kilometers per hour and driving on straight roads or curves with a radius of 230 meters or less.

ACC stands for Adaptive Cruise Control, and LKAS stands for Lane Keeping Assist System. The ACC function is like an intelligent following assistant. When I set the speed while driving, it uses radar to monitor the car in front. If the car ahead slows down, it helps me brake, and if the car speeds up, it automatically resumes the set speed. It's especially handy for long highway drives, eliminating the need to constantly press the accelerator. However, don't rely on it too much, as the radar might get confused in heavy rain or fog. As for LKAS, it's even more amazing—the camera scans the lane markings and the steering wheel automatically makes minor adjustments to avoid crossing the lines. Once when I was drowsy while driving, the car corrected the direction on its own, which was a huge help. These two features are super practical when used together, and most modern cars are equipped with them.
