“How to Use Adaptive Cruise Control

how to use adaptive cruise control


Adaptive Cruise Control (ACC) is an automotive technology that allows a vehicle to maintain a safe distance from the car ahead by automatically adjusting its speed. This system uses sensors, cameras and radar to detect the presence of other vehicles on the road and adjust its speed accordingly. ACC can be used in both highway and city driving conditions, making it an important safety feature for drivers.

Steps for Using Adaptive Cruise Control

Using adaptive cruise control is fairly simple once you understand how it works. Here are some basic steps for using this system:

  • Turn on your ACC by pressing the "ON" button located near your steering wheel or dashboard display panel.
  • Once activated, set your desired cruising speed with either buttons or a knob located near your steering wheel or dashboard display panel.
  • The ACC will then activate when you reach speeds above 25 mph (40 km/h). When another vehicle enters into range of your sensor, camera or radar, the system will automatically adjust its speed so that there is always a safe distance between you and other cars on the road.

Additional Features of Adaptive Cruise Control

  • In addition to maintaining a safe following distance between vehicles, many modern ACC systems also include additional features such as:
  • Lane Keeping Assist - which helps keep your vehicle in its lane during highway driving;
  • Stop & Go - which keeps track of traffic patterns around you and adjusts acceleration and deceleration based on those patterns;
  • Collision Warning System - which warns drivers when they are too close to another object;
  • Emergency Braking Assistance - which assists with sudden braking situations if needed;
  • Pre-Collision Mitigation System – which detects potential collisions before they happen and takes action to minimize damage if necessary.

Understanding Adaptive Cruise Control


Adaptive Cruise Control (ACC) is an advanced driver assistance system that uses sensors and algorithms to adjust a vehicle's speed in response to the flow of traffic. ACC works by monitoring the speed, direction, and distance of vehicles ahead on the road and automatically adjusting its own speed accordingly. This helps drivers maintain a safe following distance while cruising at their desired speed.


  • ACC can detect when another vehicle enters its lane or changes lanes in front of it.
  • It can also identify obstacles such as pedestrians or cyclists.
  • The system will then reduce the car's speed until it reaches a safe following distance from the other vehicle or obstacle before resuming its set cruise control speed.
  • Some systems also offer additional features such as automatic lane-keeping assist which help keep cars within their designated lane boundaries even if there are no other vehicles nearby.


The main benefit of using ACC is increased safety for both drivers and passengers by reducing instances of rear-end collisions caused by misjudging distances between cars on highways or busy city roads. Additionally, ACC provides convenience for drivers who want to maintain a steady cruising pace without having to manually adjust their speeds every time they encounter slower moving traffic ahead of them.

Operating Adaptive Cruise Control Systems


Adaptive Cruise Control (ACC) systems are a type of driver assistance technology found in many modern cars. ACC helps drivers maintain a safe speed and distance from the vehicle ahead, allowing for smoother, more comfortable journeys. It is an important part of autonomous driving technologies as it allows vehicles to react quickly to changing traffic conditions.


  • ACC reduces fatigue by taking over some of the mundane tasks associated with driving such as maintaining a constant speed and keeping a safe distance from other vehicles.
  • It can help improve fuel efficiency by avoiding sudden acceleration or deceleration when travelling at higher speeds.
  • By automatically adjusting its speed according to the flow of traffic, ACC can reduce the risk of accidents caused by human error or inattention.
  • The system can be used in conjunction with lane-keeping assist systems which help keep your car on track even if you drift out of your lane unintentionally.

How Does it Work?

ACC uses sensors such as radar and cameras to detect objects around your vehicle and adjust its speed accordingly. When another vehicle is detected ahead, the system will slow down until there is enough space between them before accelerating back up again once they have passed safely by. This process repeats itself continuously while you are driving so that you always remain at an appropriate distance from other vehicles on the road without having to manually intervene yourself every time something changes on the road ahead

Limitations of Adaptive Cruise Control

Adaptive Cruise Control Limitations

Adaptive cruise control (ACC) is a driver assistance system that helps maintain the speed of a vehicle and its distance from other vehicles on the road. While ACC can improve safety, it has some limitations that should be considered before using this feature.

Speed Limitation

The most common limitation of adaptive cruise control is its maximum speed limit. Most systems are only able to operate up to speeds of around 130 km/h, meaning they cannot be used for high-speed highway driving or racing. Additionally, some systems may not work at all in certain conditions such as heavy traffic or low visibility due to fog or rain.

Other Limitations

Other limitations of adaptive cruise control include:

  • It cannot detect objects outside its field of view such as pedestrians crossing the road;
  • It can become confused when merging lanes;
  • It does not always respond quickly enough in emergency situations;
  • It requires frequent recalibration if the car is driven over rough terrain;
  • Some models do not have an override function allowing manual control when needed; and
  • The system must be turned off manually after each use instead of automatically resetting itself once stopped.

Customizing ACC Settings for Your Vehicle


Customizing ACC settings for your vehicle is an important step towards ensuring a safe and comfortable driving experience. This process involves adjusting several parameters to suit the driver's preferences, such as speed limits, following distances and braking sensitivity. By customizing these settings, drivers can make sure their vehicles are optimized for their particular needs.

Adjusting Speed Limits

One of the most important steps in customizing ACC settings is setting appropriate speed limits. This can be done by selecting an appropriate maximum speed limit from the available options or manually entering a desired value into the system. It is recommended that drivers set realistic speed limits based on local traffic laws and conditions.

Factors to Consider When Setting Speed Limits:
  • Road type (rural vs urban)
  • Traffic density & flow rate
  • Local weather conditions

Modifying Following Distances & Braking Sensitivity

In addition to setting suitable speed limits, drivers must also adjust following distances and braking sensitivity according to their individual requirements. The ideal values should provide enough space between vehicles while still allowing for smooth acceleration/braking transitions when needed. Drivers may need to experiment with different values before settling on one that works best for them.

Staying Safe with Adaptive Cruise Control Technology
