What is the function of cruise control?

Cruise control system is also known as constant speed cruising device, speed control system, or autonomous driving system. Its function is: after setting the desired speed and switching it on, the vehicle automatically maintains the speed without the need to press the accelerator pedal, allowing the car to travel at a fixed speed. With the advancement of automotive technology, more and more cable-type throttle control methods are being rapidly replaced by electronic throttle control methods. Cable-type cruise control mainly consists of a control switch, control module (cruise computer), and servo (mechanical actuator). The working principle of the cruise control system, simply put, involves the cruise control module reading the pulse signal from the speed sensor and comparing it with the set speed, then issuing commands to the servo to mechanically adjust the throttle opening to increase or decrease, ensuring the vehicle maintains the set speed.
As a family user who frequently drives long distances, cruise control is my must-have driving tool. It automatically maintains the set speed without needing to press the accelerator pedal, keeping my foot completely relaxed—especially useful for hours on the highway. This feature enhances comfort, allowing me to chat with family or listen to music safely and stress-free. It also helps me avoid speeding tickets by keeping a constant speed within the limit—super reliable. I’ve even found it saves fuel, as steady driving lowers consumption, making it a great value for budget-conscious families. But a reminder: use it only on straight roads; switch to manual control in curves or traffic. Overall, it makes long trips easier and more enjoyable, reducing travel fatigue—a thoughtful modern car feature.
I've been driving trucks for over a decade on long-haul routes, experiencing all kinds of road conditions. Cruise control is truly a trucker's best companion. It automatically maintains your speed, preventing leg cramps from prolonged accelerator use, significantly reducing fatigue-related driving risks and improving safety. On highways, with constant speed maintained, I can focus better on observing traffic and other vehicles, decreasing accident risks. It even helps me save money by preventing speeding tickets and reducing fuel costs – multiple benefits in one. Technically, it works by controlling the throttle – simple yet practical. I recommend all long-haul drivers use this feature frequently to stay energized and confident on those endless roads.
