Cruise control automatically maintains the vehicle's speed at the driver's desired setting after activation, eliminating the need to press the accelerator pedal. This allows the vehicle to travel at a constant speed, reducing driver fatigue by removing the need to control the accelerator pedal, while also minimizing unnecessary speed variations and saving fuel. Principle of cruise control: The cruise control system primarily works by the cruise control module reading pulse signals from the vehicle speed sensor and comparing them with the preset speed. Through precise electronic calculations, it issues commands to ensure the most accurate fuel supply for the vehicle at the set speed. Precautions for cruise control: Do not use the speed control system on roads with heavy traffic or poor road conditions (such as slippery surfaces, loose gravel roads, or roads after heavy rain). Once the system is activated and the speed exceeds 40 km/h, never shift the gear lever into neutral without depressing the clutch pedal, as this may cause the engine to over-rev and result in damage. If the set cruising speed is too high compared to the current traffic conditions, do not resume the set speed.

When driving long distances on the highway, cruise control is an incredibly useful feature. It allows me to set a fixed speed, say 80 kilometers per hour, and then I don't have to keep pressing the accelerator, saving a lot of effort, especially on less congested roads. I once drove for 6 hours on the highway with my foot barely moving, unlike manual driving where my legs would go numb from fatigue. This thing can also indirectly help save some fuel costs because with a constant speed, the vehicle's combustion efficiency is better, reducing wear from frequent acceleration and deceleration. Of course, it's not suitable everywhere—like in city traffic jams, you have to turn it off to avoid delayed reactions. Overall, it's super helpful for reducing driving fatigue, making boring highway driving a bit more relaxed.

As someone who frequently monitors fuel consumption, I find cruise control quite effective in saving fuel. After setting the speed, the engine runs more smoothly, unlike manual throttle control which often fluctuates and wastes gasoline. For example, on open highways, I've tried saving over 10% on fuel costs—not only does this save money, but it's also more eco-friendly. Additionally, it reduces my need to worry about speed. Sometimes, it's easy to unconsciously accelerate while driving, but this feature helps me automatically adhere to speed limits, avoiding tickets. However, remember that road conditions must be smooth. If there are many slopes or heavy traffic, manual control is necessary to prevent issues. Overall, it's quite helpful for economical driving.

I often use cruise control on highways to enhance safety. After setting an appropriate speed limit, I can focus on the road without worrying about unintentionally accelerating and getting caught for speeding, thereby reducing accident risks. It makes driving more predictable, especially on long straight roads, as my foot doesn't need to stay tense. Some newer cars even have adaptive features that automatically adjust distance, working even better with GPS. However, I only use it in clear weather and low traffic conditions to ensure everything is safe.
