What is Adaptive Cruise Control?

If you've shopped for a new car lately, you may have come across a high-tech sounding feature called adaptive cruise control (ACC). This technology is starting to become more common on newer vehicles.

ACC builds on traditional cruise control. It uses advanced sensors to adjust your speed automatically based on traffic flow. This helps reduce driver fatigue on long trips.

Here's an in-depth look at how ACC works and the key benefits it offers compared to standard systems.

What is Adaptive Cruise Control?

How Adaptive Cruise Control Works

ACC uses a forward-facing radar and/or camera plus sophisticated software. It constantly scans for vehicles ahead of you in your lane.

When ACC detects slower traffic, it can automatically slow your car down to match their speed. This helps maintain a safe following distance.

If that car changes lanes or speeds up, ACC will then accelerate you back up to your preset speed. The system aims to perform a lot of the speed adjustment tasks on its own.

ACC also includes basic cruise control capabilities. So you can still manually set your desired speed like normal.

ACC vs. Standard Cruise Control

Standard cruise control locks onto one preset speed. You have to brake yourself when needed. ACC adds extra convenience and safety:

Automatically slows/stops in traffic - Regular cruise control will not brake. ACC slows you down when it senses slower cars ahead.

Maintains following distance - ACC uses radar to keep a safe space cushion between you and the next vehicle.

Resumes preset speed - After braking, ACC will re-accelerate back to the speed you set once the lane is clear.

Works at low speeds - ACC can operate at very low speeds and even come to a complete stop. Basic systems deactivate below 25-30 mph.

Benefits of Adaptive Cruise Control

Here are some of the useful advantages this upgraded system offers:

  • Reduce driver fatigue - The constant speed adjustments are tiring for humans over long distances. ACC does the work for you.
  • Cut down on traffic jams - By smoothling slowing down, ACC helps prevent phantom traffic jams caused by repeated braking.
  • Improve safety - Maintaining safe following distances and steady speeds improves overall traffic flow and reduces accidents.
  • Enable partial self-driving - Advanced ACC systems keep you in your lane and can bring the car to a full stop, allowing brief hands-free operation.
  • Ease congested commutes - Stop-and-go traffic is less stressful when you don't have to constantly brake and accelerate manually.

For many driving scenarios, ACC can help create a more comfortable and convenient experience. Test driving a car with well-implemented ACC can help you better appreciate the benefits.

How to Use Adaptive Cruise Control

Using ACC is simple after you learn the basics. Here are typical steps for enabling it:

  1. Press the ACC button on the steering wheel to activate the system. A light will illuminate.
  2. Get up to your desired cruising speed like normal. The current speed will show on your dash.
  3. Press Set on the steering wheel. This locks in your speed.
  4. ACC will now take over accelerating and braking to maintain speed while preventing collisions.
  5. To manually override, tap the brakes or press the gas. To fully disable ACC, press the button again.

Refer to your owner's manual for specifics on your vehicle. Controls and displays can vary between car brands.

ACC Considerations

While ACC has many benefits, it's important to know its limitations too:

  • Works above certain speeds - ACC only activates above 25-45 mph depending on the vehicle. It won't brake at very low speeds.
  • Can't detect all objects - While great at tracking cars, ACC may not see pedestrians, animals, or debris. You have to remain alert.
  • Weather can interfere - Heavy rain, snow, or fog can disrupt the sensors, forcing you to turn ACC off.
  • Hilly roads may confuse it - ACC relies on line of sight. Steep up-and-down terrain can affect its efficiency.
  • Tight curves can disable it - Some ACC systems won't work on winding or mountain roads since they can't see far enough ahead.
  • Only a driving aid - Drivers still need to pay attention and be ready to brake manually when required. ACC isn't autonomous driving.

Overall though, ACC removes a lot of the monotony and effort from cruising on straight highways with steady traffic flow. Just be prepared for situations where you'll need to take control again.

Vehicles Offering Adaptive Cruise Control

ACC technology continues to drop in price, allowing more car brands to offer it. Here are some vehicles that feature standard or optional adaptive cruise control:

Luxury Makes: Mercedes-Benz, BMW, Lexus, Audi, Tesla, Cadillac

Mainstream Brands: Subaru, Toyota, Nissan, Chevrolet, Honda, Ford

ACC is frequently bundled with other advanced driver aids as part of a package. For example, Subaru's EyeSight system includes adaptive cruise plus pre-collision braking and lane keep assist.

When shopping, look for terms like dynamic cruise control, intelligent cruise control, or autonomous cruise control. These all refer to ACC.

Test driving cars with ACC can help you determine if the functionality is refined enough to warrant the price.

ACC Cost Considerations

Adaptive cruise prices vary greatly depending on the vehicle:

  • Mainstream vehicles: Typically $500 - $2,000 when not bundled with other features. Often requires upgrading to a higher trim level.
  • Luxury vehicles: Can be standard even on base models. When an option, usually $2,000 - $4,000 packaged with other aids like lane centering.

ACC subscription services: Some automakers now offer ACC as a monthly software subscription. For example, BMW charges $25/month to add ACC to cars equipped with the required hardware.

DIY aftermarketACC: Solutions like Comma.ai's OpenPilot system add ACC to certain compatible vehicle models and trims for around $1,000 in hardware. Professional installation is recommended.

When comparing prices, take into account factors like whether ACC is bundled with other features and the level of sophistication. Higher-end ACC systems generally perform better but cost more.

The Future of Adaptive Cruise Control

Looking ahead, ACC is set to play a crucial role in the development of autonomous vehicles. As sensor technology and artificial intelligence continue to advance, we can expect ACC systems to become even more sophisticated and capable.

For instance, future ACC systems may be able to communicate with other vehicles and infrastructure (a concept known as V2X communication), allowing them to anticipate traffic conditions and adjust accordingly. This could lead to smoother, more efficient driving and even greater safety benefits.

Moreover, as electric vehicles become more common, ACC will likely be a key feature in managing battery life. By optimizing speed and acceleration, ACC can help maximize an electric vehicle's range, making it an even more valuable feature.

In conclusion, while ACC is already a transformative technology, its true potential is just beginning to be realized. As we continue to move towards a future of autonomous driving, ACC will undoubtedly be at the forefront of this exciting journey.

FAQs

What is adaptive cruise control?

Adaptive cruise control (ACC) is an advanced driver assistance technology that uses radar and cameras to automatically adjust your vehicle's speed based on traffic. It's an upgrade from traditional cruise control that only maintains a fixed speed. ACC slows down when it senses slower vehicles ahead, then speeds back up when the lane is clear.

How does adaptive cruise control work?

ACC uses sensors like radar and cameras to detect the speed of surrounding traffic. When it spots slower cars, ACC can slow your vehicle down by coasting or braking to keep a preset following distance. If those cars move or change lanes, ACC will smoothly accelerate you back up to your set speed. This provides more convenience and safety versus standard cruise control.

What's the difference between adaptive cruise control and regular cruise control?

Regular cruise control only works at higher speeds to maintain a steady preset speed. You have to brake manually when needed. ACC adds the ability to slow down and stop with traffic, resume your speed, and work at lower speeds. It aims to reduce fatigue on long drives by handling more of the speed adjustments for you.

What vehicles offer adaptive cruise control?

Many new vehicles now offer ACC, especially luxury and higher trim models. Some common brands with ACC include Mercedes, BMW, Subaru, Toyota, Ford, Nissan, and more. ACC can be standard or a $500 - $4000 add-on depending on the vehicle. Some automakers also offer it through software subscriptions.

Is adaptive cruise control worth it?

For drivers who do a lot of highway driving or long road trips, ACC can definitely be worth the cost. Key benefits include lower driver fatigue, improved safety from consistent speeds and distances, and greater comfort in stop-and-go traffic. However, ACC has limitations like problems seeing pedestrians or working on curvy roads. It shouldn't replace attentive driving.
