What does the Active Cruise Control System mean?
2 Answers
Active Cruise: The full name is Active Cruise Control System, which includes radar sensors, digital signal processors, and control modules. The working mode uses low-power radar or infrared beams to obtain the exact position of the vehicle ahead. When it detects that the vehicle ahead is slowing down or a new target is detected, the system sends an execution signal to the engine or braking system to reduce the vehicle speed, maintaining a safe driving distance from the vehicle ahead. Below is an introduction to Cruise Control: The function of Cruise Control: After setting the desired speed and turning it on, the vehicle automatically maintains the speed without the need to press the accelerator pedal, allowing the vehicle to travel at a fixed speed. Using this device, after long-distance driving on highways, drivers no longer need to control the accelerator pedal, reducing fatigue and unnecessary speed changes, which can save fuel. Requirements for installing Cruise Control: To install Cruise Control, check whether the top configuration of the vehicle model includes Cruise Control. If the top configuration has Cruise Control, the vehicle will have the wiring harness interface for Cruise Control, and you can go to a 4S store to have a professional install the Cruise Control system.
The Active Cruise Control system, also known as ACC, is a high-tech feature in cars. When driving on the highway, I just need to set my desired cruising speed, and it automatically uses radar or cameras to scan the distance to the vehicle ahead. If the car in front slows down, my car also slows down; if the car in front speeds up, it automatically accelerates to maintain my preset distance. This way, I don’t need to frequently press the accelerator or brake, making long-distance driving much easier. I’ve used several cars with ACC, and it works best on smooth highways—just press a button to activate it, reducing fatigue. However, it’s important to note that ACC relies on sensors, so in bad weather or if there’s debris on the road, the system may malfunction. That’s why I still manually monitor road conditions and never rely on it completely. The real benefit is safety—it automatically maintains a safe distance to prevent rear-end collisions.
