What does ACC mean in driving?

ACC stands for Adaptive Cruise Control. Adaptive Cruise Control can also be referred to as Active Cruise Control, similar to traditional cruise control, but the system includes radar sensors, digital signal processors, and control modules. More information about Adaptive Cruise Control is as follows: 1. In the Adaptive Cruise Control system, the system uses radar or infrared beams to determine the exact position of the vehicle ahead. If it detects that the vehicle ahead is slowing down or a new target is identified, the system sends signals to the engine or braking system to reduce speed, thereby maintaining a safe distance between the vehicle and the one ahead. 2. When the road ahead is clear, the system accelerates back to the set speed, and the radar system automatically monitors the next target. ACC takes over speed control from the driver, avoiding frequent cancellation and resetting of cruise control. Adaptive Cruise Control is suitable for various road conditions, providing drivers with a more relaxed driving experience.
Last time I drove on the highway, I finally understood that ACC stands for Adaptive Cruise Control. This thing is way smarter than regular cruise control! After setting the speed, it uses radar to monitor the distance to the car ahead and automatically controls the throttle and brakes. If the car in front speeds up, I speed up; if it slows down, the system automatically decelerates. The following distance can also be adjusted to three levels. However, when encountering sharp turns or sudden lane-cutting vehicles, the system might not react in time, so I never take my hands off the steering wheel. It does make long-distance driving much easier, but remember to turn it off in rainy weather as the radar can be easily interfered with. I recommend trying it out on a less crowded road first to get a feel for it.
ACC is a lifesaver in traffic jams! It works by using front radar or cameras to detect the position of the vehicle ahead. I always use it during my highway commute, setting the speed limit to 120 km/h and choosing a medium following distance—the system then automatically maintains the gap. The moment the car in front hits the brakes, my car slows down immediately without me needing to touch the pedals. But don’t rely on it too much—once, I got distracted checking the navigation, and even though the ACC activated when the car ahead braked suddenly, the tires still screeched a bit. Now, I stay alert when using it, since it can’t recognize road signs or traffic lights. Pairing it with lane-keeping would make it even better.
