It works in the same way as conventional cruise control by allowing you to set a speed at which the car should maintain. Other than BlueCruise and Super Cruise, the ADA systems we tested don’t make it clear to drivers when they are safe to use. Plus, we find that most vehicle owner’s manuals are overly vague, making the systems seem more like tools used to reduce manufacturer liability rather than to help drivers fully understand, and use, these high-tech features. A big difference between Ford’s BlueCruise, compared with GM’s Super Cruise and Lucid’s Highway Assist, is that BlueCruise can be used even when you’re not driving on the highway, while Super Cruise and Highway Assist cannot. Ford is able to incorporate LCA on regular, nonhighway roads because the system requires not just eyes on the road (via the DDMS) but also hands on the steering wheel in certain situations.
About Adaptive Cruise Control
Utilizing the system may add to your fatigue, as you give your vehicle more control of the journey. If you’re even the least bit tired, you should never turn on cruise control. When cruise control is no longer needed, or you need to quickly make a maneuver, simply apply pressure to the brakes to disengage the system. Once deactivated, you will be in full control of your vehicle once again. Founded in 1937, Progressive is the third largest personal car insurer in the U.S. with over 26 million drivers enrolled.
Adaptive Cruise Control FAQs
Less fuel equals more sustainability and a step closer to a greener future on the road with fewer emissions. For example, the Hyundai Elantra SEL ($22,795 with destination fee) offers its Smart Cruise Control with Stop and Go in its optional Convenience Package ($1,900). It also includes forward collision warning with automatic emergency braking, Junction-Turning Detection, navigation, wireless phone charging, heated front seats, and more. On the other hand, the same ACC system is standard for the $27,395 Elantra Limited. Here’s a rundown of the terms the various carmakers use for ACC, even those that simply call it adaptive cruise control. Although the state of autonomous driving today is Level 2, a few carmakers are on the precipice of Level 3.
Adjust speed as necessary
Such systems may use a radar, laser sensor or a camera setup allowing the vehicle to brake when it detects the car is approaching another vehicle ahead, then accelerate when traffic allows it to. The cruise control takes its speed signal from a rotating driveshaft, speedometer cable, wheel speed sensor from the engine's RPM, or internal speed pulses produced electronically by the vehicle. Most systems do not allow the use of the cruise control below a certain speed - typically around 25 or 30 mph (40 or 48 km/h). The vehicle will maintain the desired speed by pulling the throttle cable with a solenoid, a vacuum-driven servomechanism, or by using the electronic systems built into the vehicle (fully electronic) if it uses a 'drive-by-wire' system.

Cruise control systems, even adaptable cruise control, may not always detect these streets correctly, causing accidents. Heavy, or stop-and-go traffic is not ideal for safely using cruise control. When engaging cruise control on the highway, ensure your lane is clear and there are no vehicles stopping ahead. While cruise control is a convenient feature for modern drivers, it is not perfect for all circumstances. In fact, utilizing the system can be quite dangerous if you’re not careful. Quick acceleration and deceleration change the vehicle’s momentum drastically and wastes fuel.
The white Adaptive Cruise Control icon will change to green, which means the system is in use. While driving through the city, you’ll face a number of stop lights and stop signs that will require manual braking. As mentioned, cruise control may become inconsistent in rainy, snowy, or otherwise hazardous conditions.

It works largely the same as adaptive cruise control, but assists drivers with lane guidance and steering. There are several variations of semi-autonomous cruise control that include additional convenience features for the driver. If you want to speed up or slow down, use the appropriate control. Accelerating with the cruise control system in a car is like using the pedal in terms of acceleration rates and should feel familiar.
City Driving
Slowing down is akin to taking your foot off the gas and won’t slow the car as fast as applying the brake. When decelerating using the cruise control, give yourself adequate time to change speeds or use the brakes to slow down and hit the “set speed” button again. While knowing how to use cruise control can reduce leg fatigue, it can require more mental concentration.
Then there’s the concern that automatic cruise control could cause drivers to pay less attention to the road. However, this isn’t necessarily a drawback of the technology itself. If your vehicle has this available feature, Adaptive Cruise Control† allows you to set a cruise control speed and automatically follow a detected vehicle ahead at a driver-selected following gap. If no vehicle is detected in your path, the feature works like regular cruise control. Once familiar with your car’s cruise control system, you can try it out. Wait for a moment when it’s appropriate to use cruise control before turning it on.
Once Highway Driving Assist 2 determines that the driver is unresponsive, the system deactivates the LCA aspect, but the ACC will maintain the vehicle at a speed of 40 mph, without steering assistance, rather than letting the vehicle roll to a stop. Similarly, Subaru’s system also shuts off the LCA but keeps ACC on at the set speed without slowing. It’s alarming that, with the Honda and Kia systems, if a driver becomes unresponsive to warnings to put their hands on the steering wheel, the ADA systems will shut off before bringing the vehicle to a stop. This means that if the driver is distracted or medically impaired, the vehicle will just continue to roll forward—potentially off the road at speed—without any steering assistance or speed control, until it eventually rolls to a stop or runs into something. CR reached out to automakers that have an ADA system but that don’t have a camera-based driver-monitoring system, seeking comment and information on their plans.
Your vehicle will default to the type of cruise control you last used when you turned your vehicle off. When the system is turned on, you’ll see a white Adaptive Cruise Control icon in your cluster display or on your Head-Up Display, if your vehicle has that feature. The icon may look like a speedometer with a vehicle on top of it or an arc with a small triangle pointing through it. Every ACC system works slightly differently, says Kelly Funkhouser, manager for vehicle technology at CR. Some do a better job than others at recognizing merging traffic and automatically apply the brakes, while others wait too long to slow your car, requiring the driver to take control—especially when a vehicle in front of you cuts you off with a close merge. Cameras contribute with visual information, helping the system identify and track vehicles ahead.
The Mercedes and Lexus/Toyota ACC systems scored top marks for their well-tuned following-gap distance settings. Our testers found the closest setting to be comfortable in high-traffic areas while still not allowing so much space that other vehicles would continually cut in ahead. We also like that the Mercedes and Subaru ACC systems have settings that allow the driver to adjust the deceleration and acceleration force with which it slows down and speeds back up for traffic ahead. The origins of normal cruise control go back to 1948, when Ralph Teetor invented the speedostat. Having greatly improved since, its focus on throttle control is still central to automation today. One example is automatically pressing the acceleration pedal, which enables drivers to take their foot off the pedal for a few moments when they are on a motorway with low traffic.
The driver must be prepared to resume control in case of an emergency but otherwise doesn’t have command of the car. That is, the driver’s hands can be off the steering wheel and their attention elsewhere. Level 2 – To qualify as Level 2, a vehicle must have at least two driver-assistance technologies. This typically includes ACC and another technology like lane-centering assist or lane-keeping assist.
