That depends on how quickly you’re traveling, as faster-moving vehicles need more room to stop than slower ones, and your comfort level, as many systems allow drivers to adjust the gap length via a button on the steering wheel. BlueCruise is what’s known as an active driving assistance (ADA) system. In the simplest terms, ADA is the simultaneous use of a car’s adaptive cruise control (ACC) to control speed and lane centering assistance (LCA) to control steering. ACC is an advanced form of cruise control that brakes or accelerates to keep the car a set distance from vehicles traveling ahead of you in your lane. LCA provides steering support to keep the vehicle at or near the center of the lane. Adaptive cruise control or Active Cruise Control (ACC) is an advanced driver assistance system (ADAS) that automatically adjusts a vehicle’s speed when there are slow-moving vehicles ahead, with the aim of maintaining a safe following distance.

Forward collision alert and collision mitigation braking attempt to reduce the chances of drivers being involved in rear-end collisions, which are on the rise in the U.S. in part due to distracted driving from cellphone use. With semi-autonomous active safety systems becoming commonplace, more and more vehicles are beginning to offer adaptive cruise control as either optional or standard equipment. Camera-based systems use a totally different operational method, using computers to attempt to recognize objects and features from their visual representations, rather than using time-of-flight of a beam of directed energy like laser or radar.

Like other ADAS systems, ACC needs to have sensors recalibrated after a collision and many vehicle services like windshield replacement. Some ACC systems offer advanced traffic sign recognition, while others utilize GPS speed limit data. These optional ACC features help to combat the use of ACC technology to speed. In this article, we will explain adaptive cruise control and how it works, provide examples of ACC features in ADAS packages, and explain the importance of adaptive cruise control calibration.

Most of these systems also come with accident avoidance and collision warning features, like emergency braking and alert lights, to help the driver maintain a safe distance. Either a radar or laser-based system that can maintain speed, but reduces speed if the gap to the car in front falls below a preset distance. This constitutes Level One automation on the automated vehicle classification chart, as they driver is required to take control at any time. A radar and camera-based system, like Mercedes-Benz’s Distronic Plus system, uses both radars and cameras to scan the road ahead.
The sensors alert drivers to potential forward collisions and can control automatic braking and acceleration abilities as well. Luxury features on the Soul include a heated steering wheel, adjustable seats, and climate control. For an SUV specific list, view the compact SUVs with adaptive cruise control. Unlike other cruise control systems, the Pilot Assist doesn’t need a car ahead of you to determine vehicle speed.
If your vehicle has the Driver Attention System (DAS) on the steering column, Adaptive Cruise Control may automatically resume and follow the vehicle ahead for longer stops if the system detects that you're paying attention to the road. Adaptive cruise control is a system that keeps your car running at a steady set speed and reacts to changes in the pace of the car in front of you. The automatic emergency braking on vulnerable road users helps to avoid collisions, particularly with cyclists and pedestrians. The lane keeping assist detects lane markings via video camera and actively supports the driver to remain in the marked lane.

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. “The result is that Pilot Assist isn’t all that helpful to the driver. Much of this could have been solved had Volvo simply installed a driver-facing camera,” Funkhouser says. 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. We also like that even when driving on pre-mapped divided highways that are theoretically “hands-free zones,” BlueCruise requires drivers to place their hands back on the wheel in advance of risky upcoming scenarios, such as sharp curves or lane merges.
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. Both point infrared cameras at the driver’s face and sound an alert if he or she stops paying attention to the road, even if just for a few seconds.
Automatic emergency braking
When carmakers pitched cruise control to the American public more than half a century ago, they framed it as a way to maintain a safe, consistent speed on the highway and a path to conserving fuel. The major car manufacturers are all hurriedly looking to adopt adaptive cruise control technology in their latest models. If you're in the market for a car with adaptive cruise control in the UK, check out this chunky list of models (brand new ones exclusively) that might interest you. If you want a car that doesn't come with adaptive cruise control as standard, you can get it added on in the factory. Do some shopping around and also take some time to think about whether you'll actually use it and get your money's worth.
The latest ADA systems are safest to use either on long highway drives or when you’re stuck in a traffic jam—situations in which they can best reduce driver fatigue and stress. On the other hand, using these systems on narrow, curvy roads or around pedestrians can be dangerous and stressful for drivers. Volvo/Polestar’s Pilot Assist system lost points because it frequently goes into “standby” mode—which is when the system is not giving steering assistance—without a clear warning to the driver. The periodic mode changes create uncertainty as to whether the system is actively providing steering assistance or not, resulting in the driver frequently looking at the instrument panel for verification rather than keeping their eyes on the road. Fisher and other safety experts say that many of them are designed in a way that may lull drivers into complacency, giving them a false impression that the car is handling everything on their behalf.
The Insight’s cruise control system comes with a Low-Speed Follow feature. With the ProPilot Assist system activated, your vehicle can follow vehicles safely. The Pilot Assist system works to maintain a reasonable distance from other road users. The S60’s cruise control system is called the “Pilot Assist” feature. To choose a cruise speed, press the Set button while driving at the desired speed.
As such, you can easily activate it when there are no vehicles near you.

He's a die-hard motorsports fan with a passion for performance cars of all sorts. But it‘s impossible to evaluate every edge case scenario an ACC system may encounter once on the road. With so many automakers offering ACC, it‘s now an expected convenience feature for car buyers.
For most involved electric-system installations, it’s best to get them done by a dealership or certified mechanic. Installation cost depends on the sophistication of the system and the vehicle model. “Most ACC systems can only be set to speeds above 20 mph but will slow the vehicle to speeds below that in stop-and-go traffic,” she says. “There are a few systems out there that don’t bring the car all the way to a stop but instead just shut off at low speeds. That can be dangerous when you’re traveling behind another slowing vehicle.” She recommends reading the automaker’s website closely and learning about the speed ranges before using ACC while on your test drive. Every ACC system works slightly differently, says Kelly Funkhouser, manager for vehicle technology at CR.
The first adaptive cruise control (ACC) system appeared in Japan in the early 1990s, although the first systems simply warned the driver of slower traffic ahead, and didn't control the car's throttle or brakes. Hyundai’s newer system—Highway Driving Assist 2—isn’t any better than the original system in this regard. 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.
