The car will maintain speed even if road conditions change, so you must carefully pay attention to the road and traffic. When you’re using your car’s cruise control feature, don’t forget your defensive driving skills. In our most recent survey, we asked CR members to rate their experiences with the advanced safety and driver assistance systems on their model-year 2017 to 2022 cars. Respondents answered questions about their satisfaction with the systems. The systems use lasers, radar, cameras, or a combination of those. If traffic slows to a stop, most ACC systems will bring the car to a complete stop, then bring it back up to speed when traffic gets going again.
Fatigued Driving
It allows the driver to maintain a constant speed of 25 mph without holding their foot on the accelerator. Although the feature has been around for 70 years, automotive manufacturers continue to improve upon the technology to provide drivers with increased comfort, luxury, and convenience whenever they’re behind the wheel. Cruise control is best suited for long drives on large, straight roads such as an interstate highway with cars traveling at a relatively constant speed.

Subaru EyeSight Adaptive Cruise Control
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.
Car with automatic cruise control can practically drive themselves. What are the pros and cons of this technology?
If it’s longer than three seconds, driver action is needed to re-engage the system. As these systems become available on more new cars, it’s important that consumers understand their limitations. No matter what the automakers might imply in their marketing, none of the systems we tested here are capable of doing the driving for you. 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.
Cruise control is one feature you’ll want from a good car for road trips and other frequent highway driving. It can not only potentially help you get better gas mileage but also make driving much more comfortable. So, if you’ve set the speed limit to 90km and there’s no vehicle in front of you or the preceding car exceeds 90km/h, your automobile will automatically break down to the limit. Because it’s not an autonomous car, those with stop and go capabilities will only “go” again within three seconds if traffic flow allows.
The TomTom ADAS Map: designed for intelligent cruise control use cases
Mercedes equips some models, like the EQS and S-Class, with a driver-facing camera to detect inattention, but the ADA system continues to operate even if the system deems the driver to be inattentive. And the driver-monitoring camera can be switched off, even when using ADA. While some other systems do have cameras, we found that they will still function even if their cameras are covered, and in some cases the cameras can actually be turned off—neither of which is the case with BlueCruise or Super Cruise. The systems without driver-monitoring cameras require only that the driver place their hands on the wheel every once in a while, which doesn’t necessarily mean the driver is looking at the road ahead.
What is the difference between normal cruise control and adaptive cruise control?
It also implies that the system is more capable than the sum of the two features alone. Our testers evaluated how easy it was for drivers to engage the systems and make adjustments to the settings. They also reviewed the types and amount of information displayed to drivers, and how easy it was to know and understand what the system was doing.
Guide to Adaptive Cruise Control
The "resume" feature has to be used each time after selecting the new gear and releasing the clutch. Therefore, cruise control is most beneficial at motorway/highway speeds when top gear is used virtually all the time. Cruise control (also known as speed control, cruise command, autocruise, or tempomat) is a system that automatically controls the speed of an automobile. The system is a servomechanism that takes over the car's throttle to maintain a steady speed set by the driver. What I really wanted to try was the advanced driver-assistance system, and specifically the automatic lane change feature, which I had yet to test. On properly equipped 2024 model year vehicles, you can set an Adaptive Cruise Control speed while you’re stopped (the system must be on, you must apply the brake pedal and your vehicle must be in a forward gear).
With these technologies, the vehicle can steer, accelerate, and brake on its own in certain conditions. Level 2 still requires the driver’s hands on the wheel and eyes on the road. The cruise control systems of some vehicles incorporate a "speed limiter" function, which will not allow the vehicle to accelerate beyond a preset maximum; this can usually be overridden by fully depressing the accelerator pedal. Most systems will prevent the vehicle from increasing engine speed to accelerate beyond the chosen speed.
Life Lanes helps you do just that, from owning a car and home to other life moments and adventures. The most important input is the speed signal; the cruise control system does a lot with this signal. First, let's start with one of the most basic control systems you could have -- a proportional control. Mike Monticello is the manager of road tests and reviews for the autos team at Consumer Reports. Mike has been evaluating and writing about cars for nearly 25 years, having previously worked at Road & Track magazine and Edmunds.com. On the weekends, he usually switches from four wheels to two, riding one of his mountain bikes or motorcycles.
Also, if the forward-looking camera or radar sensors, if equipped, are obstructed in any way, the system will not perform as expected. Adaptive Cruise Control systems may not perform as expected where lighting is poor or when following vehicles with unusual shapes. 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. Looking ahead, as adaptive cruise control systems continue evolving, technological advancements and improved location data capabilities are set to make ACC even more predictive and adaptive. This could lead to even greater safety and efficiency benefits, further cementing the role of ACC in the sustainable transportation revolution. Toyota’s automated cruise control system, also known as Dynamic Radar Cruise Control, helps to reduce driver fatigue and offer greater comfort and security during your journey.
The 77-GHz Autocruise radar system made by TRW has a forward-looking range of up to 492 feet (150 meters), and operates at vehicle speeds ranging from 18.6 miles per hour (30 kph) to 111 mph (180 kph). Delphi's 76-GHz system can also detect objects as far away as 492 feet, and operates at speeds as low as 20 mph (32 kph). Many cars use actuators powered by engine vacuum to open and close the throttle. These systems use a small, electronically-controlled valve to regulate the vacuum in a diaphragm. This works in a similar way to the brake booster, which provides power to your brake system.

This information also provides additional data that supports accurate speed and distance adjustments. Radar technology provides critical information to the vehicle's control system. It uses sensors to emit radio waves that bounce off objects in front of the vehicle. Based on this reflection, the ACC system calculates the distance, direction and relative speed of the detected objects so it can modify the vehicle's speed and behavior accordingly. They begin with no automation and wrap up with full automation, including vehicles without pedals or steering wheels. By the early 1990s, Japanese carmakers were adding a form of forward collision warning to their cruise control, but it was still up to the driver to react and apply the brakes.
In short, this smart driving assistance makes sure everyone doesn't follow too closely behind each other, improving the safety of all traffic members from autonomous trucks to passenger cars. As stated earlier, some systems will bring your vehicle to a complete stop to match traffic flow. Even more intelligent systems can then accelerate as the traffic flow resumes. The National Transportation Safety Board (NTSB) said the driver of a Ford Mustang Mach-E who crashed into a stationary car in Texas in February was using the hands-free driver-assistance system known as BlueCruise.
Several automakers did not respond, while others declined to provide further details, saying the information is proprietary. Of those that did respond, Polestar (Volvo’s EV sub-brand) said DDMS will be included as a standard feature in its upcoming 2024 Polestar 3 SUV. Audi told us that DDMS “is not available at this time.” Rivian acknowledged that its camera is turned off in most vehicles while its Highway Assist system is active, and said it would keep CR posted on its plans for adding DDMS.
HysetCo SAS, a startup that rents hydrogen-powered EVs to taxi drivers in Paris, raised nearly €200 million ($218 million) in a round led by Hy24. To find out if your vehicle has this feature, contact your dealer or refer to your vehicle’s equipment list. Please check your Owner’s Manual for more information about features.
