What does active cruise control do?


Active cruise control is an advanced feature found in many modern vehicles that enhances the traditional cruise control system. This technology not only maintains a set speed but also adjusts the vehicle's speed based on the traffic conditions ahead. In this article, we will explore how active cruise control works, its benefits, and why it is becoming an essential feature for drivers.


How Active Cruise Control Works


Active cruise control utilizes a combination of radar and cameras to monitor the distance between your vehicle and the one in front of you. Here’s a breakdown of its functionality:



  • Speed Maintenance: Just like traditional cruise control, active cruise control allows you to set a desired speed.

  • Distance Monitoring: The system continuously measures the distance to the vehicle ahead using sensors.

  • Automatic Adjustments: If the vehicle in front slows down, active cruise control automatically reduces your speed to maintain a safe following distance.

  • Acceleration and Braking: Once the road is clear, the system will accelerate back to your set speed without any input from the driver.


Benefits of Active Cruise Control


Active cruise control offers several advantages that enhance both safety and comfort during driving:



  • Reduced Driver Fatigue: By automatically adjusting speed, it allows drivers to relax during long trips, reducing fatigue.

  • Improved Safety: Maintaining a safe distance from other vehicles helps prevent rear-end collisions.

  • Enhanced Fuel Efficiency: By optimizing speed and reducing unnecessary acceleration and braking, it can contribute to better fuel economy.

  • Convenience in Traffic: In stop-and-go traffic, some systems can even bring the vehicle to a complete stop and resume driving when traffic starts moving again.


Conclusion


Active cruise control is a significant advancement in automotive technology that not only makes driving more enjoyable but also safer. As vehicles continue to evolve, features like active cruise control will likely become standard, making our roads safer and our driving experiences more pleasant. If you're considering a new vehicle, look for this feature to enhance your driving experience.


Frequently Asked Questions

Can you use cruise control all the time?


Cruise control is best suited for long drives on large, straight roads such as an interstate highway with cars traveling at a relatively constant speed. It's inappropriate in stop-and-go traffic; when weather conditions are snowy, icy, or even heavy rain; on narrow, curvy roads; or with frequent speed limit variations.



How does Active Cruise Control work?


With Adaptive Cruise Control technology, you choose the speed you want to drive at and the system will maintain it. If the built-in RADAR sensor detects a vehicle ahead, it will slow the car to maintain a pre-set distance. Once the road in front is clear, the system will accelerate to your chosen speed.



At what speed can the cruise control be activated?


In order to start the cruise control from the standby mode, the car's current speed must be 30 km/h (20 mph) or higher.



What happens if you take a turn too fast?


Speeding into curves reduces reaction time and control, making collisions with other vehicles, pedestrians, or roadside obstacles more likely.



What is the difference between active and dynamic cruise control?


Dynamic Cruise Control (DCC) regulates the riding speed set by the rider. Active Cruise Control (ACC) regulates the selected speed in consideration of the distance to preceding vehicles set by the rider.



What are the disadvantages of cruise control in a car?


Con: Difficulty in Navigating Curves and Hills
Cruise control is less effective on roads with steep hills or sharp curves, where speed adjustments are frequently necessary. On steep inclines, the vehicle may struggle to maintain the set speed, causing it to downshift suddenly or accelerate too rapidly.



When should you not use adaptive cruise control?


The system can't detect traffic lights or traffic signs, so you still need to brake when necessary at intersections and lights. Avoid using Adaptive Cruise Control when the rear of the vehicle or truck bed is heavily loaded.



What are the disadvantages of adaptive cruise control?


Bear in mind that the adaptive cruise control is primarily intended for use when driving on level road surfaces. The function may have difficulty in keeping the correct distance from the vehicle ahead when driving on steep downhill slopes - in which case, be extra attentive and ready to brake.



When should you use adaptive cruise control?


Since many ACC systems are not designed for travel at less than 25 mph, the ACC system may turn off in a slow, heavy traffic scenario. How should you respond? Use ACC in conditions where you can drive greater than 25 mph.



Which is better, cruise control or adaptive cruise control?


Conventional Cruise Control can maintain a steady speed that you set. Adaptive cruise control (ACC) is an enhancement of conventional cruise control. ACC automatically adjusts the speed of your car to match the speed of the car in front of you. If the car ahead slows down, ACC can automatically match it.
