What is the function of cruise control system?

Cruise control system (CRUISE-CONTROL-SYSTEM), abbreviated as CCS, also known as cruise control device, speed control system, or autonomous driving system, mainly has the functions of cruise control, electronic fuel saving, throttle acceleration, speed limit setting, and brake failure alarm. The following is a related introduction to the cruise control system: 1. The cruise control system reads the pulse signal from the speed sensor and compares it with the set speed, then issues commands to mechanically adjust the throttle opening via the servo to increase or decrease, ensuring the vehicle always maintains the set speed. 2. The electronic multifunctional cruise control system eliminates the mechanical control part of the cable-type cruise control, adopting precise electronic control entirely, making the control more accurate and avoiding the risk of mechanical failure.
As someone who frequently uses this feature on long drives, I find the biggest advantage of the cruise control system is that it eliminates the need to constantly press the accelerator on highways. It automatically maintains a steady speed—for example, set at 80 km/h, the car keeps that speed without fluctuation, so I can drive for hours without leg fatigue or frustration. Especially on flat stretches, it saves effort and reduces distraction, helping avoid accidents caused by fatigue. I’ve also noticed that steady-speed driving may slightly improve fuel efficiency, as the engine doesn’t waste fuel with frequent acceleration and deceleration. However, it’s not a cure-all—it performs poorly in traffic jams or mountainous roads, often requiring manual control. Overall, this system makes driving more comfortable and safer, especially suited for travel lovers or those who often drive on highways.
