Here’s a rundown of the terms the various carmakers use for ACC, even those that simply call it adaptive cruise control. They begin with no automation and wrap up with full automation, including vehicles without pedals or steering wheels. We evaluated the systems in terms of how clearly they communicate in real time about when drivers should—and should not—be using the technology. We also looked at how well they "explain" themselves in instances when the system won’t engage or suddenly turns itself off.

Setting the Gap
This model has camera sensors that can estimate your vehicle’s proximity to other vehicles, ensuring you follow at a safe distance. The ProPilot system helps with automatic acceleration and braking to control your vehicle’s distance and speed. It also provides automatic braking and acceleration to limit driver input in situations like stop-and-go traffic. Adaptive Cruise Control calibration takes place when the camera, lidar, and radar sensors that inform your vehicle’s actions are re-aligned to improve or re-establish sensor accuracy. Like other ADAS systems, ACC needs to have sensors recalibrated after a collision and many vehicle services like windshield replacement.
Multi-sensor systems
A few internal calculations and your vehicle can tell the car’s distance and speed. Data from the radar distance sensors and the vehicle speed sensors are used to adjust your speed and keep your car a set distance from the one ahead of you. All adaptive systems control the accelerator and brake, but some go beyond that. Some can do most of the steering for you on the highway (we call this lane-centering steering assist), but require you to keep a hand firmly on the wheel. Some can go even further than that by making automated lane changes once the driver signals and the car determines it’s safe to proceed. Although adaptive cruise control is typically considered a premium feature and is often offered as an option, an increasing number of car companies are including it along with those other driver-assist technologies as standard equipment.
Ford Adaptive Cruise Control
If the vehicle has automatic transmission, and the traffic hold-up is only brief, ACC stop & go can set the vehicle in motion once again. When the vehicle remains stopped longer, the driver needs only to reactivate the system, for example by briefly stepping on the gas pedal to return to ACC mode. In this way, ACC stop & go supports the driver even in heavy traffic and traffic jams. 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.
Abilities of Adaptive Cruise Control Systems
Other safety-focused features on the F-150 models include lane-keeping system, automatic braking, hill descent control, and automatic high-beam headlights. Ford offers cruise control with the Super Duty models, along with forward-collision warning, and other safety features. The sensors alert drivers to potential forward collisions and can control automatic braking and acceleration abilities as well. Bad weather that affects road surface traction or visibility may impact its performance.
Jaguar/Land Rover, Lexus/Toyota, Tesla, and Volvo rank toward the bottom of the chart in terms of making it clear when they are (and are not) safe to use. Tesla’s Autopilot and Lexus’ Safety System+ 3.0 are both capable of being used even when there’s only a single lane line down the middle of the road, which can lead to the driver using them in an unsafe situation. The systems try to create a “center” of the lane but often end up steering too close to the unlined edge of the road. In our testing, the system consistently allowed our drivers to keep their hands fully off the steering wheel for 2 minutes and 15 seconds before the first audible warning was given to put their hands back on the wheel. “That’s simply irresponsible on the part of the automaker,” Funkhouser says. The Volkswagen Passat is another great sedan from Volkswagen that offers adaptive cruise control.
ACC + Forward Collision Warning & Automatic Braking
It maintains a set speed for your vehicle, like a conventional cruise control system, but it also adjusts the speed based on the traffic flow. Better systems can come you a full stop in heavy traffic and continue when congestion lightens. This technology can make cruise control more useful by taking some (but not all) of the workload off the driver.
Since ACC is a comfort and convenience system, brake interventions and vehicle acceleration only take place within defined limits. Even with ACC switched on, it remains the driver’s responsibility to monitor the speed and distance from the vehicle in front. Systems that are capable of controlling the steering and speed of a vehicle should also be designed to help the driver at moments of greatest need, such as an incapacitating health emergency or if the driver falls asleep at the wheel. Other than BlueCruise and Super Cruise, the ADA systems we tested don’t make it clear to drivers when they are safe to use.
Different names for Adaptive Cruise Control Systems
Radar-based ACC is often sold together with a precrash system,[43] which warns the driver and/or provides brake support if there is a high risk of a collision. Also in certain cars, it is incorporated with a lane maintaining system which provides a power steering assist to reduce steering input burden on corners when the cruise control system is activated. To increase comfort and safety of this function, a multi purpose camera can be installed in addition to the radar sensor.
This feature encourages drivers to be ready to steer if needed and doesn’t turn the LCA system off when they do. In our tests, both Mercedes-Benz and Tesla allowed the vehicle to drive down the highway hands-free for about 30 seconds before the first audible alert was given to the driver to put a hand back on the steering wheel. “That means the car could travel more than half a mile on a highway with hands off the wheel and the driver not paying attention at all—that’s a risky situation,” Funkhouser says. This improvement significantly expanded the continuous operation time of the cruise control function, as automation allowed to control both the acceleration and braking of a vehicle. This allowed the driver to travel for longer distances with their feet off the pedal, even in moderate traffic situations on the motorway.
On the other hand, using these systems on narrow, curvy roads or around pedestrians can be dangerous and stressful for drivers. GM’s Super Cruise would have scored the lowest for “displays” if it weren’t for the bright green LED indicator on the top of the steering wheel rim, which makes it clear when the system is engaged. Beyond that, Super Cruise offers little information in the instrument panel beyond a small, steering wheel icon that indicates the system is active. It doesn’t, for example, show a display of the car, lane lines, or the car ahead, as other systems do. This helps drivers understand what the system is “seeing,” and thus why the system is behaving the way it is. When there’s a seamless collaboration between the lane centering assistance system and the driver’s own steering inputs, it encourages the driver to stay alert and in control.
